Published: August 2012

Abstract
Previous studies have suggested that forest management practices can influence bark beetle populations as well as those of some associated insects. However, the impact on bark beetle-associated mites, which occur in bark beetle galleries in large numbers, have not yet been studied. The objective of this study was to compare mesostigmatid mite communities associated with the Norway spruce pest Ips typographus in managed and natural forest stands separated by spruce-free belt. The study sites were located in Białowieża National Park (NE Poland) as well as in the Izery Mountains (Szklarska Poręba Forest District — SW Poland), which were destroyed in 1981–1987 by an ecological disaster. In total, 30 Borregard pipe traps containing the commercial attractant Ipsodor W (Chemipan, Poland) were set up at each study site and collected in August 2010. In total, 7214 bark beetles and 1804 mites were collected which were classified into 16 species. We observed differences in the total abundance of mites as well as the total number of recorded mite species. The communities were quite similar, and were generally dominated by populations of Trichouropoda polytricha, Dendrolaelaps quadrisetus and Uroobovella ipidis. The Shannon and Evenness indexes as well as the mean number of mites per sample were not significantly different between forests.
Decolorization of Remazol Brilliant Blue (RBBR) and Poly R-478 dyes by Bjerkandera adusta CCBAS 930

Published: August 2012

Abstract
An anamorphic Bjerkandera adusta CCBAS 930 strain isolated from soil was found to decolorize two anthraquinonic dyes: Remazol Brilliant Blue R and Poly R-478. The reduction in the level of phenolic compounds in liquid B. adusta cultures containing RBBR and Poly R-478 was correlated with decolorization of studied dyes, which suggested their biodegradation. It was shown that this process was coupled with induction of secondary metabolism (idiophase) and peak peroxidase activity in culture medium, and the appearance of aerial mycelium. Decolorization of dyes depended on the presence of glucose (cometabolism).

Abstract
Chemical composition of the essential oil (analysed by GC-FID and GC-MS), the content of macroelements and trace elements (analysed by ICP-AES), and antimicrobial activities were investigated in Teucrium arduini L. from Mt Biokovo (Croatia). Additionally, a study on the types and distribution of glandular trichomes which produce essential oils was investigated. The oil was characterized by a high concentration of sesquiterpene hydrocarbons (68.5%) of which β-caryophyllene (32.9%) and germacrene D (16.4%) being the major compounds. Among the macroelements, the content of calcium was the highest (9772 mg/kg), while the content of sodium was the smallest (117.74 mg/kg). Among the micronutrients, the most represented element was iron (72.07 mg/kg). The content of each investigated toxic metal (As, Hg, Pb, Cd and Cr) was below permissible levels. The essential oils showed antimicrobial activity against bacterial species tested, with MIC values ranging from 6.25 mg/mL to 37.50 mg/mL. Fungal species were susceptible with MIC values from 7.81 mg/mL and 25.00 mg/mL.

Abstract
The aim of the investigations was the determination of the Cu contents in the liver, kidneys and skeletal muscles of canine females. Material for research was collected post mortem from 45 animals aged 1 to 18 years coming from the Warsaw area. The effect of the health state, age and life conditions on the distribution of copper in the investigated organs was estimated. That element was determined using the method of inductively coupled plasma-atomic emission spectrometry (ICP-AES). In the liver, the average Cu contents amounted to 24.04 mg kg−1 wet weight, in kidneys to 2.90 mg kg−1 wet weight and in muscles to 0.94 mg kg−1 wet weight. The highest values of copper content in particular tissues and organs were noted in the group of animals with neoplastic changes. In respect to the animal age the highest mean values of the copper content were noted in the oldest animals. They amounted to 30.97 mg kg−1 in the liver, 3.34 mg kg−1 in kidneys and 1.18 mg kg−1 wet weight in muscles. Considering life conditions of the dogs it was observed that the higher mean values in all the investigated organs occurred in dogs coming from the urban areas.

Published: August 2012

Abstract
Uncinaria spp. parasites were collected from two Tsushima leopard cats found on Tsushima Island, Nagasaki prefecture, Japan. One Uncinaria sp. was observed in the large intestines, and the other was observed in the small intestines. The nematode found in the large intestines was determined to be Uncinaria felidis by morphological identification. The other Uncinaria sp. found in the small intestines was morphologically different from U. felidis in the short-length of prevulvar flap. After isolation of genomic DNA of these worms, a second internal transcribed spacer (ITS2) of ribosomal DNA was amplified and sequenced using PCR techniques. The ITS2 region of U. felidis had 222 nucleotide sequences in length. The alignments of ITS2 sequence for Uncinaria felidis and Uncinaria sp. showed one nucleotide (0.45 %) replacement. These differrences may be regarded as intraspecific variation.

Abstract
We present a case of 53 years old patient with transplanted kidney, chronic hepatitis C and alveolar echinococcosis who was treated with pegylated interferon α which resulted in regression and calcification of Echinococcus multilocularis loculi. Patient had been diagnosed with chronic hepatitis C two years after kidney transplantation. Hepatitis was left untreated because of immunosuppressive treatment and satisfactory graft function. Nine years after transplantation the patient was diagnosed with alveolar echinococcosis and treated with mebendazole 2 × 200 mg daily for 6 months. Cessation of temporary treatment resulted in echinococcosis progression with appearance of secondary loculi and a small ascites after which mebendazole was restarted. Ten years after transplantation, kidney graft failure occurred and the patient was started on hemodialysis in conjunction with pegylated-interferon alpha 2a for treatment of chronic viral hepatitis C. Complete early viral response was observed 3 months after therapy initiation while a follow-up CT scan after 4 months did not document any changes in the number or size of E. multilocularis loculi. A completed course of antiviral therapy resulted in sustained viral response while a subsequent second follow-up CT scan 6 months after cessation of antiviral therapy documented regression and calcification of main E. multilocularis loculi along with resolution of secondary loculi and ascites.

Abstract
The aim of the present experiment was to assess the clinical, haematological, biochemical and immunological responses of pigs experimentally infected with Trichinella spiralis. One group of 6 pigs was infected with 1500 larvae/kg body weight and one group of 7, was maintained as control. The highest larval density was in the diaphragm (504.3 ± 8.2). During the experimental T. spiralis infection in pigs, increased values of total granulocyte number, eosinophils, blood glucose, K+ concentration, CK, ALT, AST and ALP were registered in different stages of infection. A slight increase of the phagocytic activity was registered 14 days p.i., in the infected group. Significantly increased values in lymphocyte activity, in infected group, was observed 30 and 60 days p.i. comparative with control. The specific IgG antibodies were detectable by ELISA at 14 days p.i. The results obtained in this study provide a better understanding about complete interactions occurring during Trichinella infection in pigs.
Presence of Bucephalus polymorphus, Echinoparyphium recurvatum and Aspidogaster limacoides (Platodes, Trematoda) in the visceral mass of Dreissena polymorpha (Mollusca, Bivalvia)
Authors: Lajtner J. 
Published: August 2012

Abstract
The invasive bivalve species Dreissena polymorpha (Pallas, 1771) has become one of the most dominant spe-cies in many lakes and rivers of Europe and North Ame-rica. The aim of this study was to investigate changes in the structure of the visceral mass depending on the repro-ductive cycle and to determine the presence and effects of trematodes on the zebra mussel. Mussels were collected from the Dubrava dam reservoir during eight sampling sessions from January to December 2000. For histological analysis, 80 mussels were placed in Bouin’s fixative for 24 hours, embedded in paraffin and cut with a microtome into 10 μm slices. The sections were then stained with haema-toxylin and eosin. Analysis of non-infected bivalves indi-cated that gametogenesis started in late summer, while spawning began in April. In July, the majority of mussels were in the post-spawning stage. Two mussels were in-fected with Bucephalus polymorphus, one with Echi-noparyphium recurvatum and one with Aspidogaster lima-coides. Obtained results demonstrated that the gonads were the most affected organs in mussels infected by B. poly-morphus, the infection by A. limacoides resulted in a sig-nificant reduction of all investigated organs, while the infection by E. recurvatum had no visible pathogenic changes in the structure of visceral mass.

Published: August 2012

Abstract
To determine whether canine faecal contamination may represent a source of environmental contamination with Toxocara canis eggs within the urban area of Florence, a total number of 754 dog faeces were collected in 7 public places and examined by routine floatation technique during one-year period. The total prevalence of intestinal nematode eggs was 8.6 %. Trichuris vulpis (4.6 %) eggs were the most prevalent followed by T. canis (3.6 %) and Ancylostomidae (1.7 %) eggs. Mixed infections included T. canis/T. vulpis (0.7 %), Ancylostomidae/T. canis (0.4 %), and Ancylosto-midae/T. vulpis (0.3 %). Total prevalence of intestinal nematode eggs was significantly higher in spring than in winter (OR = 2.06). Our results indicate a low prevalence of T. canis eggs suggesting that dog faeces left on soil are unlikely to cause high environmental contamination with T. canis eggs in the town of Florence.

Published: August 2012

Abstract
During December 2007 and November–April 2008/2009, 128 gastrointestinal tracts and 1680 faecal samples of hares from different parts of the Czech Republic were examined. Evaluation of the faeces samples indicated that the samples could have been infected with any one of the following parasites: Eimeria spp., Trichostrongylus retortaeformis, Trichuris leporis, Graphidium strigosum, Strongyloides sp., Protostrongylus spp. and Anoplocephalidae tape-worms. Trichostrongylus retortaeformis was the most common nematode (75.8 %). 39.8 % of the animals were infected with Trichuris leporis. Only four hares were in-fected with Graphidium strigosum. Eimeria spp. was the most commonly occurring parasite (90.5 %). The follow-ing species were found: Eimeria coquelinae, E. cabareti, E. leporis, E. babatica, E. europea, E. pierrecouderti, E. macrosculpta, E. orbiculata and E. stefanski. Eimeria coquelinae was the most prevalent species (68.4 %). Eimeria cabareti and E. leporis were the next most frequently found species (64.5 % and 57.8 %, respectively).

Published: August 2012

Abstract
We examined the endoparasites of wild nutria from the native region of South America. Individuals were infected with nineteen species, including Nematoda (82.0 %), Protozoa (46.1 %), Trematoda (33.3 %) and Cestoda (12.8%). Coccidia (Eimeria sp. or Isospora sp.), Strongyloides myopotami and Trichuris myocastoris were the most abundant and prevalent parasites. The diversity of parasite collected on individual hosts ranged from one to four species. There was no significant association between either the age or the sex of the nutria and the prevalence of parasitism, except that the number of infested nutria less than 1 year by Nematoda was significantly higher than in older individuals. Additionally, Cryptosporidium spp. and Giardia spp. were demonstrated in fecal samples, although scarcely. In general, the accessions were found in good bodily condition and carrying low parasite burdens. These numbers appeared insufficient to indicate gastrointestinal parasitism or parasitic disease.
Morphometrical analysis of Taenia taeniaeformis and Taenia crassiceps in the common vole (Microtus arvalis) and the water vole (Arvicola terrestris) in Vorarlberg, Austria
Authors: Fuehrer H. , Siehs C. , Schneider R. , Auer H. 
Published: August 2012

Abstract
Taenia taeniaeformis and Taenia crassiceps are cestodes with voles as intermediate hosts and Felidae, Canidae and Mustelidae as definitive hosts. To evaluate the influence of T. taeniaeformis metacestodes on voles in Vorarlberg (Western Austria), a helminthological survey was performed on 318 common voles (Microtus arvalis) and 93 water voles (Arvicola terrestris). Furthermore the metacestodes themselves were analysed by morphometric methods. Our results demonstrate that both T. taeniaeformis and T. crassiceps are endemic in Vorarlberg, and that there is a significant difference between those infected with larvae of T. taeniaeformis and uninfected voles regarding body weight, but not sex or body length.

Abstract
A new species of ascaridoid nematode, Hysterothylacium anguillae sp. n. (family Anisakidae), is described based on specimens recovered from the stomach and intestine of the giant mottled eel Anguilla marmorata Quoy et Gaimard from the Mngazi River, South Africa, collected in March–April 2011. It is characterized mainly by poorly developed lateral alae, a very short intestinal caecum and a long ventricular appendix, spicules 1.11–2.14 mm long (representing 5.2–5.8 % of body length), number of caudal papillae (19–21 pairs of preanals, 2 adanals and 5 postanals), presence of a median precloacal papilla (= ventromedian organ), tail tips of both sexes covered by minute spines, and by the shape and structure of lips. This is the first nominal species of Hysterothylacium described from an African freshwater fish and the second species of this genus reported from freshwater eels of the family Anguillidae. The following Indian congeneric species are considered species inquirendae: Hysterothalacium aetobathum Lakshmi, 2005, H. carutti Lakshmi, Rao et Shyamasundari, 1993, H. channai Lakshmi, 1995, H. fossillii Lakshmi, 1996, H. japonicum Rajialakshmi, 1996, H. kiranii Lakshmi, 1993, H. longicaecum Lakshmi, Rao et Shyamansundari, 1993, H. narayensis Lakshmi, 1997, H. nellorensis Lakshmi, 1996, H. neocornutum Rajialakshmi, Rao et Shyamasundari, 1992 and H. punctati Lakshmi, 1995. Of them, H. japonicum and H. neocornutum are transferred to Iheringascaris Pereira, 1935 as I. japonica (Rajialakshmi, 1996) comb. n. and I. neocornuta (Rajialakshmi, Rao et Shyamasundari, 1992) comb. n.

Published: August 2012

Abstract
Males of Aphelenchoides limberi are described and illustrated for the first time from mushroom plate cultures of Botrytis cinerea. The original parthenogenetic population was extracted from the soil of a hop garden in Senice na Hané, Czech Republic. The males are characterized by a stylet about 11 μm long, a prominent spicula, with the dorsal limb longer than the ventral limb, and a ventrally curved tip. The tail is arcuate, conoid, ending with a short, mostly ventrally bent hook-shaped mucro, the lateral field appears to have four lines under light microscopy.

♦Background The leptin/adiponectin (L/A) ratio has been suggested to be an atherosclerotic index for diabetic patients and a useful marker of insulin resistance in patients with and without diabetes. Even though end-stage renal disease (ESRD) patients on peritoneal dialysis (PD) are well characterized by abnormal adipocytokine metabolism, the significance of alterations in the L/A ratio is largely unexplored in these patients. In this prospective study, we investigated the associations of leptin, adiponectin, and the L/A ratio with clinical outcomes in nondiabetic PD patients. ♦Methods The study included 131 stable nondiabetic ESRD patients who had been on PD for more than 3 months. Serum leptin and adiponectin levels were determined at baseline. Mortality was evaluated over a 5-year follow-up period. ♦Results During the follow-up period, 22 patients died (16.8%), including 10 (45.5%) as a result of cardiovascular disease. The L/A ratio showed a significant positive correlation with body mass index [BMI ( r = 0.47, p < 0.001)], high-sensitivity C-reactive protein ( r = 0.32, p < 0.001), and triglycerides ( r = 0.43, p < 0.001). In addition, we observed significant inverse correlations between the L/A ratio and percentage lean body mass ( r = –0.30, p = 0.001) and high-density lipoprotein cholesterol ( r = –0.31, p = 0.001). In contrast to individual leptin and adiponectin levels, the L/A ratio was found to be independently associated with an increased mortality risk (relative risk: 1.15; 95% confidence interval: 1.05 to 1.27; p = 0.003) even after adjustments for age and BMI. ♦Conclusions The L/A ratio might be better related to patient outcomes than adipocytokines are individually in nondiabetic patients undergoing PD.
Predicting 12-Month Mortality for Peritoneal Dialysis Patients Using the “Surprise” Question

Published: August 2012

♦Background Studies in hemodialysis patients suggest that the “surprise” question can help to identify a group of patients with a high mortality risk who should receive priority for palliative care interventions. However, the same instrument has not been tested in peritoneal dialysis (PD) patients. ♦Method We studied 367 prevalent PD patients from a single dialysis center. Three clinicians independently answered the “surprise” question (Would I be surprised if this patient died within the next 12 months?) according to their clinical impression of the individual patient. Patients are then classified into “yes” (yes, surprised) and “no” (no, not surprised) groups. All patients were followed for 12 months. ♦Results In this cohort, 109 patients (29.7%) were allocated to the “no” group, and 258 (70.3%), to the “yes” group. Patients in the “no” group were older and had high prevalences of pre-existing ischemic heart disease, cerebrovascular disease, and peripheral vascular disease. The “no” group had a higher score on the Charlson comorbidity index and a higher malnutrition–inflammation score. At 12 months, 44 patients had died. Mortality was 24.8% in the “no” group and 6.6% in the “yes” group. Multivariate analysis showed that an opinion of “Not surprised if dies in the next 12 months” was an independent predictor of 12-month mortality, with an associated 3.594 excess mortality risk (95% confidence interval: 1.411 to 9.151; p = 0.007). The positive predictive value of this opinion was 24.8%, and its negative predictive value was 93.4%. ♦Conclusions The “surprise” question has the potential to help identify a group of PD patients with high short-term mortality. Its use may contribute to a decision to refer PD patients for early palliative care assessment.

Published: August 2012

Objective.To determine the prevalence of renal disease and the course of renal function over time in patients with systemic sclerosis (SSc).Methods.We performed a multicenter, longitudinal study of 561 patients with SSc followed in the Canadian Scleroderma Research Group registry. Renal function was measured by the estimated creatinine clearance rate (eCcr) using the Cockcroft-Gault formula. Longitudinal changes in renal function were modeled using statistical analyses that adjusted for patient dropout.Results.Among the study subjects, 112 (20%) had abnormal renal function with no history of scleroderma renal crisis (SRC) and 29 (5%) had a history of SRC at baseline. In models adjusting for patient dropout, we found that patients with abnormal baseline renal function experienced the same annual decline in eCcr as patients with normal baseline renal function (−0.89% per year, 95% CI −2.02%, 0.26%), which is similar to that observed in the general population. Patients with a history of SRC also showed the same rate of decline, although starting from a lower baseline.Conclusion.Renal dysfunction is common in SSc, even among those without a history of SRC. It is generally mild and renal function declines at a rate similar to the general population. These data are of considerable prognostic value for clinicians caring for patients with SSc.
