title: EFFECTS OF A NEW INTRAVENOUS ELECTROLYTE SOLUTION FOR USE IN VETERINARY PRACTICE ON THE ELECTROLYTE AND ACID-BASE BALANCES OF HEALTHY CATTLE

description: Abstract The effects of a new intravenous polyionic solution on electrolyte and acid-base balances in cattle were evaluated. Eight healthy adult, crossbred Bos taurus cattle received two treatments in a cross-over design: isotonic saline solution (IS) and test solution (TS) with 145 mEq of Na+, 5 mEq of K+, 4 mEq of Ca++, 2 mEq of Mg++, 96 mEq of Cl-, 60 mEq of lactate, 50 g of dextrose, and 4 mg of cyanocobalamin per liter. The solutions were IV infused in a volume corresponding to 5% of BW, through 3 hours. Venous blood samples were taken before the infusion and 3, 6, 9, and 24 hours after the beginning of the infusion. Glucose, L-lactate, Ca, P, Mg, pH, pCO2, HCO3-, BE, Na+, K+, Cl-, and Ca++ were measured. Data were analyzed through repeated measures ANOVA. IS caused acidifying effect due to hyperchloremia and decreased plasma strong ion difference (SID). On the contrary, TS induced mild and transient alkalinization without changes in Na+ and Cl- plasma levels. Transient hypokalemia and hyperglycemia were presented at the end of the ST infusion but did not provoke apparent clinical signs. We concluded that TS is a safe choice for fluid therapy in cattle, inducing low magnitude iatrogenic changes as an advantage.

title: ANTIMICROBIAL ACTIVITY OF COPAIFERA SPP. AGAINST BACTERIA ISOLATED FROM MILK OF COWS WITH MASTITIS

description: Abstract The antimicrobial activities of the oleoresin (OR) and the essential oil (EO) of Copaifera spp. were checked against microorganisms isolated from milk samples of cows diagnosed with grade III subclinical mastitis. The OR had good antimicrobial activity (MIC ≤ 100 µg/mL) against samples of coagulase-positive Staphylococcus, coagulase-negative Staphylococcus, Streptococcus of groups C, F, and G, and Corynebacterium spp. Meanwhile, the EO had good antimicrobial activity (MIC≤100 µg/mL) against coagulase-negative Staphylococcus and Corynebacterium spp. The OR and the EO were inactive and weak to inactive, respectively, against Escherichia coli. Overall, the OR had better antimicrobial activity than the essential oil against the 55 bacterial isolates (p&lt;0.0001). The GC/MS analysis identified sesquiterpenes in EO and by the ESI FT-ICR MS method, the identification of diterpenic acids in OR was possible. Therefore, this raw plant material is promising for the development of phytotherapeutic drugs against bovine mastitis.

title: SEROEPIDEMIOLOGY OF TOXOPLASMOSIS IN HUMANS AND DOGS FROM A SMALL MUNICIPALITY IN PARANA, BRAZIL

description: Abstract Toxoplasmosis is a worldwide zoonosis with important public health implications. The aims of this study were to determine and identify factors associated to the seroprevalence of anti-Toxoplasma gondii antibodies in humans and dogs from Jataizinho, Parana State, Brazil. Serum samples from 280 humans and 766 dogs, from rural and urban areas, were tested by indirect immunofluorescent antibody test. Positive dilutions were ≥ 1:16. Epidemiological informations were obtained through an individual questionnaire and data tabulation was performed using EpiInfo 3.5.3 (CDC, Atlanta). Statistical significance was evaluated by chi-square (ᵪ2) or Fisher's exact tests with a 5.0 % significance level. The seroprevalence in humans was 70.00% (196/280), as follows: 69.08% (143/207) in rural and 72.60% (53/73) in a slum urban community. The seroprevalence in dogs was 52.35% (401/766), as follows: 71.74% (99/138) in rural and 48.08% (302/628) in urban area. In rural areas, there was no factor associated to risk of infection. In urban slum community, visualizing more than four rats at home was a factor statistically associated to seropositivity for human toxoplamosis. Infection of urban dogs was associated to age, contact with stray dogs or rodents, and free access to street. The results indicated a similar possibility of contact with Toxoplasma gondii between dogs and humans living in rural or slum urban areas of small municipalities.

title: Brucella ovis IN SHEEP: SEROPOSITIVITY AND RISK FACTORS

description: Abstract Seroepidemiological study of Brucella ovis in sheep from Sergipe State was carried out to determine the seropositivity and infection distribution in rural properties and possible factors associated with infection. A total of 54 sheep properties were studied and 932 blood serum samples from animals older than six months were collected in the three regions of Sergipe State. All sera samples were examined by agar gel immunodiffusion (AGID). According to the serological tests, 46.30% (25/54) of the properties had serologic evidence of infection by B. ovis, with 4.40% of positive animals (41/932). Presence of sheep handler (OR=2.31) and properties with an area bigger than 50 ha (OR=1.98) were observed as factors associated with B. ovis infection, whereas the use of stall (OR=0.37) worked as a protective factor (OR=0.40). Thus, the presence of antibodies against B. ovis in Sergipe State was confirmed, and it highlights the importance of complementary studies to determine the specific health measures in herds to prevent this disease.

title: CURRALEIRO CATTLE BREED HEALTH STATUS FOR NEOSPOROSIS AND TOXOPLASMOSIS

description: Abstract This study compared the health status of Curraleiro cattle and other breeds (Nellore, Girolando, Guzera, and Caracu) for toxoplasmosis and neosporosis screening against anti-Neospora caninum and anti-Toxoplasma gondii antibodies, respectively. We used 119 female bovines of Curraleiro, Guzera, Nellore, Caracu, and Girolando breeds from four farms in Goias and Tocantins states and in the border of Goias, Minas Gerais, and Bahia states. All the farms had seropositive bovines for N. caninum. The number of seropositive Curraleiro cattle was significantly higher than the number of Guzera and Nellore cattle. Also, antibodies against toxoplasmosis were found in animals from all properties. There was no significant difference between the number of seropositive Curraleiro cattle and the breeds Nellore, Girolando, and Guzerá; however, it was significantly higher than the number of seropositive animals of Caracu breed.

title: ERADICATION PROGRAM OF FOOT AND MOUTH DISEASE IN THE STATE OF SÃO PAULO: EVALUATION OF OFFICIAL DATA OBTAINED BETWEEN 1997-2012

description: Abstract Foot and mouth disease (FMD), a highly contagious disease that affects cloven-hoofed animals, is known by the economic losses it causes in farms and in regions where it is endemic. The State of São Paulo has not recorded FMD outbreaks since 1996. Based on official data from 1997 to 2012, this study organized, analyzed, and confronted the following information with the current literature: a) the FMD vaccination rates from 1997 to 2012 in São Paulo; b) the results of the official monitoring designed to demonstrate the effectiveness of vaccination against FMD; c) the passive surveillance procedures and compliance with reports of suspected vesicular disease in the State of São Paulo; d) the results of the official monitoring designed to demonstrate the absence of viral circulation in the State of São Paulo; e) the relation between the preventive measures adopted by the veterinarian official service with the challenge of FMD outbreaks in other neighboring states. Finally, the description of the free area without vaccination implementation prospects for the State of São Paulo, classification granted by the World Organization for Animal Health (OIE). The data analysis showed that sanitary measures, strategies, and the methodology to assess the efficacy of the FMD eradication program in the State of São Paulo were efficient. Even though the data suggest that the state is able to upgrade to a FMD free area without vaccination, some aspects should be taken into account, such as the structure of the state's Official Veterinary Service, disease control programs in states epidemiologically related with São Paulo and the commitment of the whole supply chain with surveillance and eradication of FMD.

title: PLURIPARITY IN MARES: RELATIONSHIP WITH MATERNAL, PLACENTAL, AND NEONATAL CHARACTERISTICS

description: Abstract The placenta connects the mare and the foal and it is one of the main organs responsible for fetal development and newborn’s morphometric characteristics. This function becomes even more important because a number of studies indicates that foals physical characteristics are able to predict their development in adult life. Therefore, the aim of this study was to correlate mares parity (1-5) and maternal characteristics with placental characteristics as well as foals size. Mares were categorized according to parity in G1: 1 parturation (n=4); G2: 2 parturations (n=6); G3: 3 parturations (n=7); G4: 4 parturations (n=5); and G5: 5 parturations (n=3). Results indicate that the mares pre- and post-parturition thoracic perimeter and weight had a positive correlation on foals weight (p=0.004/ R= 0.51; p=0.002/ R= 0.55; p=0.01/ R= 0.43), height (p=0.0005/ R= 0.60; p=0.001/ R= 0.57; p=0.005/ R= 0,50), and thoracic perimeter (p=0.0001/ R= 0.65; p≤0.0001/ R= 0.71; p=0.0002/ R= 0.64) at birth. Mares that were heavier at pre-partum had greater placental weight (p=0.01/R= 0.45) and delivered heavier foals (p=0.003/ R= 0.52) with greater thoracic perimeter (p=0.01/ R= 0.45). Foals of mares in G4 were heavier, probably indicating that the greater uterine size in multiparous mares allows greater placental coverage, greater fetomaternal surface contact and probably greater supply of nutrient to the fetus.

title: ISOLATION AND CULTURE OF MESENCHYMAL STEM CELLS DERIVED FROM ADIPOSE TISSUE AND BONE MARROW OF DOGS

description: Abstract The objective of this study was to establish a protocol for the isolation and culture of mesenchymal stem cells (MSC) from bone marrow and adipose tissue of dogs. Three 6-month-old male dogs were used. Approximately 3.0 cm3 of adipose tissue and 3.0 mL of bone marrow were collected. The samples were processed and the isolated cells were cultured in DMEM. The cells were subjected to phenotypic characterization and to osteogenic, adipogenic, and condrogenic differentiation to confirm the isolation of the MSC. The cells showed elongated and fusiform morphology and they were able to differentiate into osteoblasts, adipocytes, and chondrocytes. Phenotypic characterization revealed high expression of the MSC markers CD90(80.04%) and CD29(96%) in the cells from bone marrow and high expression of CD90(60.94%) and CD29(77.08%) in the cells from adipose tissue. In addition, phenotypic characterization revealed low expression of hematopoietic markers CD45(1.45%) and CD34(1.53%) in the cells from bone marrow and low expression of CD45(1.45%) and CD34(1.53%) in the cells from adipose tissue. Based on these results, the modifications applied to classical protocols simplified the process and proved to be efficient in the isolation, culture, and expansion of MSC isolated from the bone marrow and adipose tissue of dogs.

title: EFFECT OF PLATELET-RICH PLASMA GEL ON GRAFT SKIN HEALING IN EQUINES

description: Abstract The platelet-rich plasma (PRP) gel is an autologous platelet concentration in a small plasma volume with the potential to improve the integration of the grafts. Eight adult equines were used, performing skin grafts, with 2.5x2.5 centimeters, on both sides of the neck, in which one was the treatment side, using the PRP gel, and the other side was the control. The animals were assessed after the surgery on days 0, 7, 14, 21, and 28, by clinical, histological, morphometric, and culture analysis of the grafts. The clinical, morphological, and biological analysis of tissue grafts revealed no significant differences between the control group and the treatment group with PRP. Histologic evaluation revealed an increase in acute inflammation on day 7 and collagen concentration on day 14, resulting from the release of growth factors by the platelets present in the gel, which did not differ in further moments. According to the experimental conditions used in this study, we concluded there were no significant differences between the side treated with PRP and the control side in skin grafts in horses.
