Introduction: Recently in Europe an increase in the population of red deer (Cervus elaphus), roe deer (Capreolus capreolus), and fallow deer (Dama dama) has been observed. Research on the prevalence of Leptospira infections in Polish cervids has been performed for the first time.

Introduction: Although HEV infection in pigs does not pose a major economic risk to pork production, the risk of zoonotic transmission to humans is an important aspect of public health. HEV genotype 3 infections were reported in developed countries in individuals who had consumed raw meat or meat products from deer, wild boars, or pigs. The aim of the study was the analysis of the occurrence of HEV-specific antibodies among wild boars and domestic pigs in Poland. Material and Methods: A total of 290 samples from wild boars and 143 samples from pigs were tested. The antibodies were tested by ELISA. Results: The presence of anti-HEV IgG was demonstrated in 44.1% of pigs and 31.0% of wild boars. Anti-HEV IgG antibodies were detected in 1.4% of samples from pigs and in 2.1% of samples from wild boars at borderline level. The statistical analysis shows significant differences in the positive results for anti-HEV IgG between the groups of pigs and wild boars (P = 0.0263). Conclusion: Regular surveillance of the occurrence of HEV in swine and wild boars should be performed in the future.

Serum samples from 83 free living wild pigs (Sus scrofa) from the Nhecolândia region, Pantanal do Mato Grosso, Brazil, were examined for the presence of antibodies against Neospora caninum by means of the indirect fluorescence antibody test (IFAT) with a cut off of 50. Antibodies were present in 10.8%, with titers of: 1:200 in one animal, 1:400 in four and 1:800 in four. Analysis using the χ2 test showed an association between sex and presence of antibodies, with females showing occurrence of 20.5% and males 2.3% (p = 0.017). No association was found between age and occurrences of antibodies against this parasite. This was the first observation of N. caninum antibodies in Brazilian wild pigs from Pantanal.

Toxoplasmosis and neosporosis are diseases that may affect production animals and cause significant economic losses. Given the importance of this fact, risk factors and occurrence of antibodies anti-Toxoplasma gondii and anti-Neospora caninum were determined for 81 sheep in seven farms of the Guarapuava region, state of Paraná, Brazil. Indirect fluorescence antibody test (IFAT) showed antibody frequency of 40.74% for T. gondii and 3.70% for N. caninum. The risk factors evaluated were: for T. gondii, direct contact of sheep with cats and for N. caninum, with dogs; abortion in the herd; and access of other animal species to the same water tank used by the sheep. CI (95%), Odds Ratio, and p value were determined by Fisher Exact Test. No statistical difference was observed between the occurrence of antibodies and risk factors associated with the presence of antibodies against both parasites. It may be stated that the protozoa T. gondii and N. caninum are found in the sheep herds of this region.

Objective: Caprine arthritis encephalitis (CAE) infection is existing worldwide causing economic loss in goat production. This work was conducted to investigate the prevalence of CAE in local and foreign goat breeds and sheep in different localities in Sudan.Materials and methods: A total of 368 sera samples were prepared; among these, 112 were collected from cross (n=39) and foreign (n=73) breeds of goat in Khartoum state, equal number of sera (n=23) were collected from goats and sheep from each of River Nile, Gedarif, Sinnar and North Kordofan states. Eighteen cross bred goats were tested from River Nile state. From foreign bred goats, 28 and 26 sera were collected from Gazira and Northern states, respectively. The collected sera were examined for the presence of antibodies to CAE virus using Enzymed-Linked Immunosorbent Assay (ELISA).Results: The overall seroprevalence of CAE was 2.99% (n=11/368). Positive results were found only in 11 of foreign breed of goats (Cyprus shami) collected from Gazira (39.29%; n=11/28). Statistically, there was an association between breed and location (P=0.001 and P=0.671, respectively). Conclusion: The CAE virus infection exists only in foreign goat breeds. Gazira state showed the highest seroprevalence as compared to other states considered in this study. Strict hygienic measures should be adopted to control the disease and to prevent its spread to local breeds. [J Adv Vet Anim Res 2016; 3(3.000): 259-262]
