n this study, 30, 15 and 1 strains of Pasteurella multocida and 9, 8 and 6 strains of Mannheimia haemolytica from cattle, sheep and goats isolated in Elazig province located in the East of Turkey, respectively were typed by random amplified polymorphic DNA (RAPD) assay using a random primer (OPA-11). By RAPD assay, two and three distinct band profiles were obtained in the examination of P. multocida isolates from cattle and sheep, respectively. However, M. haemolytica isolates from cattle, sheep and goats showed only one profile and these strains were not discriminated by RAPD. This study...

A parasitological survey of 255 rats, trapped in rural regions of Croatia, was carried out. The survey revealed infection with 7 helminth species (2 cestodes, 5 nematodes and eggs of 2 accidental parasites). Also, 8 ectoparasite species (2 fleas, 3 lice, and 3 mites) were found. Overall infection rate was 72.6% (185 infected out of 255 rats). Eighty two of 255 rats (32.2%) were infected with ectoparasites and 166 out of 255 (65.1%) with endoparasites. Among endoparasites the most frequent parasite was Hymenolepis diminuta (36.9%) and among ectoparasites Polyplax spinulosa (14.5%). Analysing association of parasite infection...

The level of risk for human health originating from organs of slaughter pigs was determined on the basis of carcass inspection classification at slaughterhouses in the Czech Republic during the period of 1995-2002. The following pig's organs were included in the study: the lungs, heart, liver, spleen, kidneys, stomach, and intestines. A potential level of risk relating to food safety of different organs was determined according to the numbers of the organs condemned by official veterinarians. At the same time total number of slaughtered animals was also considered. The trend of the development of potential risk was determined as an index equal to the...

Since their discovery in 1945, tetracyclines have been used extensively in the therapy and prophylaxis of infectious diseases and as growth promoters. These wide applications have led to the equally fast spread of tetracycline resistant strains of gram-positive and gram-negative bacterial genera, including strains belonging to pathogenic as well as nonpathogenic species. Nonpathogenic bacteria could act as a reservoir of resistance determinants, which can be disseminated by horizontal transfer into pathogens. More than thirty different tetracycline resistance genes have been characterized. They encode two major mechanisms of resistance: 1 - active...
