Fibrotic myopathy in the horse
Authors: Turner A. S. , Trotter G. W. 
Published: February 2025

Summary
The case histories of 18 horses with hindlimb lameness attributed to fibrotic myopathy were reviewed. In 14 horses, the problem developed after trauma. In 5 others, it developed secondary to intramuscular injections. Other causes of the lameness were surgery, exertional injuries, and purpura hemorrhagica. Eleven of the horses were treated by resection of scar tissue or by semitendinosus myotenotomy. Postoperative complications included pressure necrosis under quill sutures (9 horses), acute disruption of the skin incision (2 horses), dehiscence of the wound during healing (2 horses), and prolonged hemorrhage from the wound (1 horse). Of the 9 horses that were available for follow-up examination, 1 was free of lameness, 7 had various degrees of improvement, and 1 had no improvement.
Preparation of veterinary gross anatomy specimens: A method that allows storage at room temperature for four years
Authors: Kinnamon Kenneth E. , Holborow George S. , Simmonds Richard C. , Sheridan Michael N. 
Published: February 2025

SUMMARY
On the basis of methods used to prepare human anatomic specimens, 2 Yucatan miniature pigs were embalmed over 4 years ago. Results obtained suggest that specimens commonly used in the teaching of veterinary gross anatomy may be fixed in this manner. Advantages include no requirement for refrigeration, superior long-term preservation, less offensive odor, and better tissue texture qualities, including less evidence of dehydration.
Porcine Haemophilus pleuropneumonia: Microbiologic and pathologic findings
Authors: Didier Peter J. , Perino Louis , Urbance John 
Published: February 2025

SUMMARY
Haemophilus pleuropneumoniae was isolated from 11% of porcine lung specimens submitted to the University of Illinois Diagnostic Laboratory during 1979-1982.
Acute necrotizing fibrinous bronchopneumonia was the most common diagnosis; 65% of lungs had severe involvement of the caudal lobes; 10% of lungs had unilateral involvement only. In 46% of lungs, a second pathogen was isolated.
Isolates of H pleuropneumoniae tested by the Kirby-Bauer disk method were most sensitive to nitrofurazone (100%), polymyxin B (97%), chloramphenicol (95%), gentamicin (94%), sulfachloropyridazine (87%), ampicillin (83%), and penicillin (77%). Isolates were less sensitive to 9 other antimicrobials tested. Over 4 years in 1 herd, succeeding isolates of H pleuropneumoniae developed resistance to ampicillin, streptomycin, bacitracin, lincomycin, penicillin, and tetracycline.
Small intestine incarceration through the epiploic foramen of the horse
Authors: Turner Tracy A. , Adams Stephen B. , White Nathaniel A. 
Published: February 2025

SUMMARY
Fifteen horses were referred to Purdue University or to the University of Georgia because of colic. Each of these horses had small intestine incarcerated through the epiploic foramen. However, signs of pain, gastric reflux, and small intestine distention were not consistent signs, as would have been expected with small intestine strangulation/obstruction. In 10 of the 15 cases, abdominal fluid analysis provided the decisive information needed for surgical intervention.
Surgery was performed in 14 cases. The small intestine was incarcerated through the epiploic foramen in a right-to-left direction in 12 cases and in a left-to-right direction in 3 cases. The intestinal incarceration was reduced by gentle traction on the adjacent unaffected intestine. Resection and anastomosis were performed in 10 cases. Twelve of the 14 surgical patients died, and it was believed that the failure to intervene surgically at an earlier time contributed to these poor results. Surgery was delayed in most cases because of the inconsistent clinical signs observed in these horses. It was concluded that small intestine incarceration through the epiploic foramen should be suspected in any case of colic that has inconsistent physical findings and does not resolve in short time. Further, serial abdominal fluid analysis should be used in such cases in order to detect changes or trends that would indicate a lesion requiring surgical intervention.
Cytauxzoonosis in domestic cats: Report of two cases in Oklahoma, with a review and discussion of the disease
Authors: Glenn Bertis L. , Stair Ernest L. 
Published: February 2025

SUMMARY
In 2 cases of cytauxzoonosis in domestic cats in Oklahoma, the clinical features, gross lesions, and microscopic findings were of similar nature and degree to those previously reported by others, both in the naturally occurring and experimentally induced disease. Intraerythrocytic forms of Cytauxzoon felis organisms were demonstrated in stained blood smears from one cat. Blood from the other cat was not examined. The diagnosis was established by the finding of schizonts in endothelial-associated macrophages within vascular channels in tissues from both cats.
Thermodilution curves for diagnosis of ventricular septal defect in cattle
Authors: McGuirk S. M. , Welker F. H. , Muir W. W. , Hull B. L. 
Published: February 2025

Summary
An indicator dilution method developed for detection of intracardiac shunts and determination of cardiac output in man and domestic animals was evaluated in 4 calves and 1 cow with holosystolic cardiac murmurs. Thermodilution curves recorded from the pulmonary artery and the right ventricle confirmed a left-to-right intracardiac shunt and provided a means for its quantitation. Ventricular septal defect was confirmed in 2 cows, which were euthanatized. The data obtained by thermodilution were evaluated along with information obtained from other diagnostic procedures (auscultation, oximetry, echocardiography, measurement of intravascular pressures). It was concluded that the procedure is a simple and accurate method for diagnosis of ventricular septal defect in cattle.
Factors relating to urine spraying and fighting in prepubertally gonadectomized cats
Authors: Hart Benjamin L. , Cooper Leslie 
Published: February 2025

Summary
The fact that male cats are routinely castrated prior to full sexual maturity for behavioral reasons prompted a survey of the prevalence of these behaviors in prepubertally gonadectomized male and female cats. About 10% of the 134 male and 5% of the 152 female cats studied engaged in spraying on a frequent basis later in adult life. Problem spraying and fighting in males was of the same order of magnitude as in males castrated in adulthood after the problem behaviors had appeared. The age of prepubertal castration, ranging from 6 to 10 months, had no influence on spraying or fighting later in life. It was found that male cats are more likely to spray and fight if they are in households with female cats than with other male cats. With regard to female cats, spraying or fighting was less than that of male cats. Age at the time of gonadectomy was not a factor in their tendency to spray or fight. Possible prenatal masculinization of female fetuses by male fetuses, as revealed by littermate composition, was not a factor in the predisposition of female cats to spray or fight.
Pelvic bladder in dogs without urinary incontinence
Authors: Mahaffey M. B. , Barsanti J. A. , Barber D. L. , Crowell W. A. 
Published: February 2025

SUMMARY
Double-contrast cystography was performed simultaneously with cystometrography in 6 male and 6 female dogs. All dogs were continent, and results of urinalyses were normal. Initial radiographs were made following intravesical infusion of 0.88 ml of positive contrast medium/kg of body weight. Additional radiographs were made during infusion of CO2. The last radiographs were made at the time of detrusor reflex (11 dogs) or when intravesical pressure reached 50 cm H2O (1 female). An average of 34% range, 11% to 67%) of bladder length was within the pelvic canal when only the positive contrast medium was infused into the bladders. By the end of CO2 infusion, the bladder neck was more cranially located in 5 of 6 males and in 5 of 6 females. On the last radiographs made, an average of 19% (range, 10% to 35%) of bladder length was within the pelvic canal in 3 of 6 males and in 4 of 6 females. The bladder neck was rounded in 10 of 12 dogs. Thus, it was concluded that previous reports associating pelvic urinary bladder with urinary incontinence and other urologic abnormalities are questionable.
Treatment of central tarsal bone fractures in the racing Greyhound
Authors: Boudrieau Randy J. , Dee Jon F. , Dee Larry G. 
Published: February 2025

SUMMARY
Methods of repair of central tarsal bone (Tc) fractures in the racing greyhound can involve coaptation, single-screw fixation, or 2-screw fixation. Successful management, defined as a return to competitive racing, was obtained in 71% of 114 affected dogs treated by these methods. Both 1- and 2-screw fixation, with interfragmentary compression, was used to repair Tc fractures in 81 dogs. It was concluded that satisfactory results can be expected by use of open reduction and screw fixation in all types of Tc fractures except those that are severely comminuted.
Mycoplasma as a cause of canine urinary tract infection
Authors: Jang Spencer S. , Ling Gerald V. , Yamamoto Richard , Wolf Alice M. 
Published: February 2025

SUMMARY
Mycoplasmas were isolated from 60 specimens of urine obtained by cystocentesis from 41 dogs (23 males and 18 females) with urinary tract infection. Mycoplasmas were isolated in pure culture from 41 (68%) of the specimens, and were isolated in conjunction with one or more bacterial species from 19 (32%) specimens. Clinical signs of urinary tract infection were noted in 20 of 31 dogs in which mycoplasmas were isolated in pure culture, and numbers of wbc in the urine sediment were above the reported normal range in 22 of 25 urine specimens from those 20 dogs. Twenty-four of 29 mycoplasma isolates were found to be Mycoplasma canis, 4 were found to be M spumans, and 1 was identified as M cynos.
Results of surgical excision of perianal fistulas in dogs
Authors: Vasseur P. B. 
Published: February 2025

SUMMARY
Eighty-seven dogs that had perianal fistulas diagnosed at the Veterinary Medical Teaching Hospital, University of California, Davis, were treated by excision of the diseased tissues and bilateral anal sacculectomy. Males were affected more often than females (66 to 21), and the German Shepherd Dog was the predominant breed (59 of 87). Information from owners regarding long-term postoperative progress was available for 41 dogs. Twenty-two of the 41 dogs had been euthanatized, 15 (36.6%) because of complications related to perianal fistulus and 7 because of unrelated causes. The mean postoperative period, ie, from the time of surgery to the time of euthanasia, was 34.7 months (range, 1 to 82 months). The remaining 19 dogs were examined after a mean postoperative period of 42.3 months (range, 13 to 100 months). Postoperative complications included development of clinically evident fistulas in 23 of the 41 dogs (56.1%), lack of normal continence (26.8%), tenesmus (19.5%), flatulence (17.1%), and anal stricture (14.6%). Twenty-one of the 41 dogs (51.2%) were judged by their owners to be satisfactory pets or to have been satisfactory pets before euthanasia for unrelated reasons.
Results of tube gastrostomy as treatment for gastric volvulus in the dog
Authors: Flanders James A. , Harvey H. Jay 
Published: February 2025

SUMMARY
The Dragstedt modification of the Stamm tube gastrostomy was used in 29 dogs with gastric volvulus. A total of 17 dogs were monitored for 14 to 40 months after surgery. Volvulus recurred in one dog. All dogs with a presumptive diagnosis of gastric volvulus were treated surgically by gastric derotation and gastrostomy on an emergency basis. Mortality during the first week after surgery was 31%.
Effects of dietary chloride restriction in lactating dairy cows
Authors: Fettman M. J. , Chase L. E. , Bentinck-Smith J. , Coppock C. E. , Zinn S. A. 
Published: February 2025

SUMMARY
Early-lactation Holstein cows fed a corn silage-based diet low in chloride and supplemented with sodium bicarbonate were observed for clinical, metabolic, and production alterations over the course of 8 to 11 weeks. In 3 of the more severely affected cows, metabolic derangements included a rapidly developing primary hypochloremic, secondary hypokalemic and hyponatremic metabolic alkalosis, and hemoconcentration. Clinical signs included severe hypophagia, weight loss, muscle weakness, hypogalactia, dehydration, constipation, cardiopulmonary depression, and a depraved appetite. It was concluded that the rapid progression of these derangements, apart from any anatomic abnormalities or infectious causes, emphasizes the need for rapid assessment and therapeutic intervention in primary imbalance associated with body chloride depletion and metabolic alkalosis.
Evaluation of techniques for diagnosis of canine prostatic diseases
Authors: Barsanti Jeanne A. , Finco Delmar R. 
Published: February 2025

SUMMARY
Bacterial culture and cytology of semen, bacterial culture and cytology of prostatic fluid washings, urinalysis, bacterial culture of urine, and blood leukocyte counts were performed on specimens from dogs with prostatic hyperplasia, chronic prostatitis, or prostatic neoplasia.
Hemorrhage was the most frequent abnormal finding in semen from dogs with prostatic hyperplasia. Inflammation was the most frequent abnormal finding in dogs with chronic prostatitis. Bacterial culture of semen was sensitive but not specific for chronic bacterial prostatitis, due to false-positive results from urethral contamination.
Hemorrhage was the most frequent abnormal finding in prostatic fluid washings from dogs with prostatic hyperplasia. Inflammation was the most frequent abnormal finding in dogs with chronic prostatitis. Abnormal epithelial cells were found after prostatic massage in 4 dogs with neoplasia, although these cells were difficult to identify as neoplastic. Prostatic fluid washings were not useful for detecting chronic bacterial prostatitis, due to an inability to detect increases in bacterial counts in the fluid when urine bacterial counts were high.
Hematuria was the predominant abnormal finding in urinalysis from dogs with hyperplasia and neoplasia. Pyuria was the most frequent abnormal finding in dogs with chronic prostatitis. Urine was usually culture-positive when there was prostatic infection.
Blood leukocyte counts were normal in dogs with prostatic hyperplasia and usually normal in dogs with neoplasia. Leukocytosis, a left shift, and toxic white blood cells were predictive of abscessation, although the blood leukocyte count was not a very sensitive indicator for infection without abscessation.
Prognostic factors for feline mammary tumors
Authors: MacEwen E. Gregory , Hayes Audrey A. , Harvey H. Jay , Patnaik Amiya K. , Mooney Samantha , Passe Sharon 
Published: February 2025

SUMMARY
The case records of 100 cats with malignant mammary tumors were reviewed. All cats were staged clinically according to the staging system of the World Health Organization. The following information was obtained from the medical records: age at time of diagnosis, breed, tumor size, date of surgery, type of surgical procedure performed, histologic type of tumor, disease-free interval, survival time, and cause of death. Factors of no prognostic value were age (≤ 10 years vs >10 years) and breed. Tumor size was the most significant prognostic factor (P<0.0001). Cats with small tumors (1 cm3 to 8 cm3) had the best prognosis. The type of surgery, conservative vs radical, was significantly (P<0.01) related to disease-free interval, but was of no significance in prolonging survival time.
Serratia spp infection in 21 horses
Authors: Colahan P. T. , Peyton L. C. , Connelly M. R. , Peterson R. 
Published: February 2025

SUMMARY
Twenty-three isolations of Serratia spp were made from 21 horses at the University of Florida Veterinary Medical Teaching Hospital between Jan 1, 1979 and July 1, 1983. Three Serratia spp were involved in single-organism and mixed infections of various tissues. Eight horses of this group died. All horses that died had massive, mixed, gram-negative infection. The other 13 responded to treatment, including systemic antibiotic therapy. Most of these horses were stressed and under antibiotic therapy prior to the time of culture. Possible nosocomial infection, variable antibiotic sensitivity, and a trend toward decreased antibiotic sensitivity after antibiotic administration were noted.
Prostaglandin treatment and subsequent cystic ovarian disease in Holstein cows
Authors: Jasko David J. , Erb Hollis N. , White Maurice E. , Smith R. David 
Published: February 2025

SUMMARY
Using computerized herd health data, a prospective cohort study was devised to determine whether cows treated with prostaglandins had a higher incidence of cystic ovarian disease than comparable cows not treated. Of 744 cows selected as having diseases for which prostaglandin administration may be indicated, 240 received prostaglandin. Sixteen cows had cystic ovarian disease following prostaglandin administration. Chi-square analysis showed no association (P>0.10) between cystic ovarian disease and the use of prostaglandin.
Incidence of cystic ovarian disease within 150 days of calving in clinically normal cows was compared with that of cows with reproductive disorders. Cows with reproductive disorders had a significantly (P<0.01) higher incidence of cystic ovarian disease.
Effect of atropine sulfate on tear production in the cat when used with ketamine hydrochloride and acetylpromazine maleate
Authors: Arnett Beth D. , Brightman Alan H. , Musselman Eugene E. 
Published: February 2025

SUMMARY
Schirmer I tear tests were done on 10 cats before and during anesthesia induced with ketamine hydrochloride in combination with acetylpromazine maleate, with and without atropine sulfate as a preanesthetic agent. Use of atropine sulfate alone decreased tear production from a mean base-line value of 16.9 ± 3.7 mm/min to 8.2 ± 4.9 mm/min, 10 minutes after its subcutaneous administration. Tear production continued to decrease from 8.2 ± 4.9 mm/ min to a mean of 2.3 ± 2.5 mm/min at 30 minutes after the administration of the ketamine hydrochloride and acetylpromazine maleate combination.
Radiographic appearance of pulmonary metastases from transitional cell carcinoma of the bladder and urethra of the dog
Authors: Walter P. A. , Haynes J. S. , Feeney D. A. , Johnston G. R. 
Published: February 2025

SUMMARY
Eleven cases of histologically proven transitional cell carcinoma of the bladder or urethra of the dog were selected for evaluation and characterization of the varied radiographic appearances of the lungs. In the 8 dogs with metastases, those appearances included radiographically normal pulmonary parenchyma, a semidense, diffuse, lacelike haze referred to as interstitial opacity, nodular interstitial opacity, and consolidations. One affected dog had hilar lymphadenopathy. In the 3 dogs without pulmonary metastases, the radiographic appearance was either normal pulmonary parenchyma or increased unstructured interstitial opacity.
Of all dogs in the study, 6 had a radiographic appearance of increased unstructured interstitial opacity. Four of those 6 had histologically proven metastases in the peribronchiolar lymphatics or alveolar capillaries. Dyspnea was not identified in any of the affected dogs.
The radiographic appearance for 3 of the 8 dogs with pulmonary metastases was misinterpreted as opacity compatible with age. The radiographic appearance for 1 of the 3 dogs without pulmonary metastases was misinterpreted as highly suspect for metastases.
Paraovarian-omental bands as a cause of small intestinal obstruction in cows
Authors: Richardson D. W. 
Published: February 2025

SUMMARY
Small intestinal obstruction caused by a fibrous band extending from the free edge of the greater omentum to the ovary or the tip of uterine horn was found in 4 cows. The band and distended small intestine were palpable per rectum in each cow. In 3 cows, severance of the fibrous band relieved the small intestinal obstruction and the cows recovered without complication. In the fourth cow, the compromised portion of intestine ruptured during manipulation and the animal was euthanatized.
Effect of immunosuppressive drug therapy on blood urea nitrogen concentration in dogs with azotemia
Authors: Finco Delmar R. , Barsanti Jeanne A. , Rawlings Clarence A. 
Published: February 2025

Summary
Azotemic dogs receiving prednisone and azathioprine to enhance renal allograft survival had higher blood urea nitrogen (bun): serum creatinine (sc) ratios, when compared with nontreated dogs with induced azotemia. The difference in ratios probably was attributable to increased bun content secondary to the catabolic effects of the drugs used. However, dogs with naturally occurring renal failure had bun:sc ratios that were similar to those for dogs receiving the catabolic drugs. It was concluded that even though catabolic drugs may influence bun:sc ratios, the multiplicity of other factors affecting bun and sc may interact to cause a wide range of bun:sc ratios under conditions of naturally occurring primary renal failure in the dog.
Medial condylar fractures of the third metatarsal bone in horses
Authors: Richardson D. W. 
Published: February 2025

Summary
Fifteen longitudinal fractures involving the medial condyle of the third metatarsal bone were diagnosed in racing Thoroughbreds and Standardbreds. Twelve were repaired surgically with lag screws placed through stab incisions. Two of the horses suffered catastrophic fracture of the third metatarsal bone during recovery from anesthesia, and 3 more sustained complete fractures within 4 days of the repair. Of 3 horses with fractures treated without surgery, 2 healed without complication. Preoperative radiography did not demonstrate a nonlongitudinal fracture component in any of the horses that sustained complete fractures. The complete fractures were uniformly “Y” shaped. Horses in which the fractures healed had a good prognosis for return to racing.
Equine plasma banking: Collection by exsanguination
Authors: Eicker Steven W. , Ainsworth Dorothy M. 
Published: February 2025

Summary
A procedure was developed for the collection, preparation, storage, and administration of equine plasma. The technique involved exsanguination of anesthetized donor horses via carotid artery catheterization with a large-bore cannula. Blood was collected into plastic bags, allowed to settle by gravity, then transferred into storage bags and frozen. These were quickly thawed when needed.
A survey of adverse effects associated with ivermectin use in Louisiana horses
Authors: Karns P. A. , Luther D. G. 
Published: February 2025

Summary
In a survey of 13 Louisiana equine practices, it was determined that 366 of 3,316 horses developed adverse reactions following use of ivermectin, with 3 of the horses having more than 1 reaction. Almost all of the reactions were of minor to moderate concern; however, 1 death was reported. Three hundred and thirty-two (91% of all reactions) were reported as ventral midline pruritus or edema (10% of all doses). Fifteen (0.45%) were transient injection site swelling and/or stiffness. Eleven horses (0.33%) developed limb edema. Eyelid edema was reported in 4 horses (0.12%). Two horses (0.06%) had fever. Rate and depth of respiration was increased in 1 horse (0.03%). One horse (0.03%) became disoriented. Three horses (0.09%) developed signs of colic. One horse (0.03%) died a few minutes after injection, and 1 horse (0.03%) became depressed. The survey covered the period from March to August of 1983.
