This work presents the results of findings for brucellosis in wild boars and domestic swine in two regions of Croatia. In the region of Djakovo the blood samples of 211 wild boars were analysed and in 29.4% of the samples serologically positive reactions were established. In the same region the blood samples of 1080 domestic swine on pastures were also analysed and positive serological reactions were established in 12.3%. In the regions around Lonjsko Polje the blood samples of 53 wild boars were analysed and in 22.6% of them positive serological reactions were established. On several locations around Lonjsko Polje the blood samples of 901 domestic swine were serologically analysed and 13.5% of the swine were found to be seropositive. Bacteriological analyses of submitted materials from 24 wild boars resulted in isolation of Brucella from seven (29.2%) samples, and from 43 samples originating from domestic swine that had aborted and had been serologically positive, Brucella were isolated from 25 (58.1%) swine, as well as from 10 (62.5%) out of 16 aborted piglets. In all the isolates Brucellasuis biovar 2 was identified. Wild boars are carriers and reservoirs of Brucellasuis biovar 2 in Croatia.

ABSTRACT: Family Tayassuidae in the suborder Suina include two species of peccaries in Brazil: the white-lipped peccary (Tayassu pecari) and the collared peccary (Pecari tajacu). These animals share common pathogens with domestic swine (Sus scrofa); however, their role as potential carrier remains unclear. This study focused on detecting the prevalence of influenza A antibodies in Tayassu pecari and Pecari tajacu from commercial rearing farms from two states in Brazil. A set of 50 blood samples from Pecari tajacu and 55 from Tayassu pecari were analyzed using a commercial indirect ELISA in order to investigate anti influenza A antibodies. Pecari tajacu samples presented 22% (11/50) of seropositivity for the virus. Serological surveillance is an important tool to identify the presence and the spread of the influenza virus in feral pigs.

During the years 2001 and 2002 on seven localities in Croatiaa survey on the prevalence of brucellosis in wild boar was carried out. The survey included 271 (52.7%) female and 243 (47.3%) male animals between 7 months and 4 years of age and weighing from 14 to 135 kg. On that occasion 514 blood samples of wild boar were serologically analysed. For serological analysis indirect enzyme immunoassay (iELISA), Rose Bengal test (RBT), complement fixation test (CFT) and slow agglutination test (SAT) were used. In all of the wild boar from all of the localities investigated positive reactions to brucellosis were established. Most of the positive reactions were established by iELISA (13.6%), then by RBT (11.5%), CFT (10.5%) and SAT (8.9%). Tissue samples of 106 animals: testes samples from 67 animals, uterus tissue from 38 animals and 5 fetuses of piglets from 1 mother were analysed bacteriologically. Brucella suis biovar 2 was isolated from 18 (17.0%) animals that originated from all of the localities investigated. Isolates were identified by PCR using BRU-UP and BRU-LOW primers specific for genus Brucella and primers specific for IS711. Based on our results it could be concluded that in Croatia wild boar are natural vector and/or reservoirs of B. suis biovar 2. This permanent risk factor is hazardious for domestic and wild animals in theRepublic ofCroatia.

SUMMARYHigh brucellosis seroprevalence rates in domestic swine herds have been reported in Wallis and Futuna Islands and are associated with a significant burden of human infection by Brucella suis, a species that is rarely incriminated in human disease. Between 2003 and 2010, seven patients had a positive blood culture for B. suis biovar 1, 11 symptomatic patients had a positive Rose Bengal test (RBT) and a positive serum agglutination test (SAT) and three asymptomatic cases were found to be positive for RBT, SAT or ELISA IgM (after systematic screening of 52 family members of 15 index cases). Overall, Brucella infection was diagnosed in 21 people, corresponding to a mean annual incidence of 19 cases/100 000 inhabitants. Compared to series of patients infected with other more commonly encountered Brucella spp. such as B. melitensis and B. abortus, clinical presentation and percentage and distribution of complications were similar, apart from a marked observation of significantly increased median alanine aminotransferase levels, 20 times greater than upper normal rates, but not accompanied by any particular hepatic pathology. Wallis and Futuna, where people live in close proximity to animals and where the cultural significance of pig-raising precludes the implementation of adequate veterinary preventive measures, thus represents one of the few known B. suis foci worldwide and allows for evaluation of the peculiarities of this infection.

Epidemiological Situation

Abstract The research aimed at evaluating the epizootic and epidemiological situation of trichinosis during the last 8 years in Lublin province on a background of progressing increase in wild boar population within the region and in the whole country. Data for the study were taken from the report on the results of the official examination of slaughter animals and meat, poultry, game, lagomorphs and aquaculture animals and six reports on the number of trichinosis cases found at wild boars and domestic swine. In order to evaluate the trichinosis epidemiological situation within the region, reports of the National Institute of Public Health-National Institute of Hygiene on the number of identified trichinosis cases in people, as well as the number of hospitalised patients were presented. In addition, information on the population and hunting achievement of wild boars in hunting circuits of Lublin province during the last 8 years was enclosed. The number of identified trichinosis cases in meat of wild boars from Lublin region increased 9 times, while the percentage of trichinosis occurrence in reference to the number of examined carcasses almost 3-fold. At the same period, the number of porcine carcasses, in which trichinosis was found, decreased by over 4 times. Over double increase in wild boar population on the studied area was observed during the evaluation. Dynamic increase in the population size - in an aspect of the species population interaction with the living habitat, and in the form of the increase in the number of damages of crops and cultivation fields - contributed to intensified hunting pressure towards the species expressed as almost 3-fold increase of wild boar hunting. Analysis of epizootic and epidemiological situation of Poland indicates that wild boar meat was the principal source of trichinosis during the studied period. Considering Lublin province, the number of identified trichinosis cases is still high as compared to eastern and central provinces. Meanwhile, when compared to western and northern Poland, the level of trichinosis invasion can be considered as low. Furthermore, the trichinosis morbidity among people, that does not exceed 0.18/100 thousand inhabitants, can be regarded as low. Nevertheless, the fact of underestimating the necessity of both wild boar’s and swine’s meat examination seems to be alarming

Hepatitis E virus (HEV) infection is widespread among domestic pigs, industrial swine, and wild boars in Bulgaria. The aim of the current research was to present the HEV seroprevalence among blood donors in Bulgaria. In the present study, 555 blood donors (479 males and 76 females) were enrolled from five districts in the country (Shumen, Pleven, Stara Zagora, Plovdiv, and Sofia districts). All blood samples were tested for anti-HEV IgG using the recomWell HEV IgG ELISA test (Mikrogen GmbH, Neuried, Germany). Each participating donor completed a short, structured, and specific questionnaire to document data on the current study. Anti-HEV IgG positive results were detected in 144 (25.9%) blood donors, including 129 (26.9%) males and 15 (19.7%) females. The established HEV seropositivity was 28.8% (23/80) in Shumen district, 23.2% (22/95) in Pleven district, 27.1% (38/140) in Stara Zagora district, 27.5% (44/160) in Plovdiv district, and 21.3% (17/80) in Sofia district. A high HEV seroprevalence was found for persons who declared that they were general hunters (48.7%; 19/39; p = 0.001) and hunters of wild boars (51.6%; 16/31; p = 0.001). We present the first seroprevalence rates of HEV infection in blood donors from Bulgaria. The results of our research showed high HEV seropositivity among blood donors.
