Viruses cause many diseases in plants, animals, and humans. They are strict intracellular parasites with cellular specificity. Viral particles can be transmitted by different routes, such as contaminated food and water. People usually get infected orally, after ingestion of products contaminated during processing or subsequent handling or preparation. This review article is focused on the most severe foodborne viruses specific for humans, of the following genera: Norovirus, Enterovirus, Hepatovirus, Astrovirus, and some others. Methods for detecting viruses in food and strategies for preventing virus transmission via food are also discussed.

A geographic information system was used for the analysis of ecological conditions of distribution of natural foci of brucellosis in the European hare (Lepus europaeus) and their long-term persistence in the Czech Republic. The European hare is a reservoir host of Brucella suis biotype 2. A close correlation was found between the geographic distribution and numbers of natural foci of brucellosis in the Czech Republic in 1971 to 1985 and 1986 to 2000 (r = 0.65, n = 814, P = 0.01). Natural foci of brucellosis were persistent, but not stationary, over the period of 30 years. Natural foci of brucellosis were...

Ninety-three rectal swabs of lambs and young goats from two extensively and two intensively managed herds in Jordanwere taken and examined for Shiga toxin-producing Escherichia coli (STEC). The bacteriological examination included the preenrichment of rectal swabs in EC broth with novobiocin, and a subsequent parallel isolation on enterohemolysin agar and immunomagnetic separation with cultivation on CT-SMAC. The STEC O157:H7 strains were demonstrated in 8 of 32 diarrheic lambs 1- to 3-weeks old in one sheep herd with intensive milk production. In the remaining three herds, serogroups O128, O78, O15 and serotype O128:K85 of STEC strains were...
Immunohistochemical characterisation of cholinergic nerve fibres supplying accessory genital glands in the pig

Our previous immunohistochemical investigations revealed three major populations of nerve fibres supplying the porcine accessory genital glands (AGG) including noradrenergic, non-noradrenergic putative cholinergic and sensory nerve terminals (Kaleczyc et al., 1997). However, it is still unclear whether the non-noradrenergic nerve fibres are cholinergic in nature. The knowledge of the population of cholinergic nerve fibres in mammalian AGG based upon vesicular acetylcholine transporter (VAChT) immunohistochemistry is very limited. Therefore, the aim of the present investigation was to disclose the occurrence and colocalization patterns of VAChT, dopamineâ-hydroxylase...

: The circulus arteriosus cerebri of the porcupine was investigated in this study. Five porcupines were used. Coloured latex was given from the left ventricles of three and from the communis carotid artery of two porcupines. The circulus arteriosus cerebri was examined after dissection was done. The basilar artery was formed by a merge of the right and left vertebral artery. The caudal communicans artery which was the caudal part of circulus arteriosus cerebri was formed by the basilar artery on crus cerebri. From caudal to cranial, the branches originating from the basilar artery and circulus arteriosus cerebri to cerebrum and cerebellum were as follows:...
Transmission electron microscopy of the vitreous body tissue in chronic hemophthalmos

Haemolytic products arising in chronic hemophthalmos cause cellular infiltration, necrosis of the vitreous structure, and fibrous membrane formation. In this process, retinal pigment epithelium plays an important role for its antioxidant properties and the capability to phagocyte the decay products.
