A total of 924 questing Dermacentor reticulatus (Fabricius), 504 Ixodes ricinus (L.), sixty Haemaphysalis concinna Koch and 718 mosquitoes (Aedes spp.) were examined in a floodplain forest ecosystem during the 1994-95 outbreak of tularaemia in South Moravia, Czech Republic. Francisella tularensis was not isolated from H.concinna ticks or Aedes spp.(More)
In 1984-1991, the incidence of salmonellas was studied in wild birds from various sites in the Czech Republic. On an agricultural farm with salmonellosis in calves, salmonellae were isolated from eight birds (seven Passer domesticus, one Serinus serinus) of 31 birds examined. On various agricultural farms with no salmonellosis in farm animals, salmonellae(More)
Mycobacterium avium subsp. avium (MAA) of serotype 2 and genotype IS901+ and IS1245+ was cultured from 21 naturally infected hens (Gallus domesticus) from one smallholder aviary. From a total of 330 samples taken from hens, 124 mycobacteria were detected. Out of which MAA was detected in 103 (35.7%) of 288 tissues, in 4 (19.0%) of 21 swabs of cloacae and in(More)
A total of 429 specimens belonging to 9 species of small mammals, trapped in various areas of the Czech Republic during the year 2001, were examined for antibodies against leptospires. Antibodies were found in all localities under study in 50 specimens, i.e., 11.6%, belonging to 5 species. Antibodies were most often , i.e., in 42% of positives, found in(More)
European brown hares (Lepus europaeus) coming from the Czech Republic, Slovakia and Austria were tested for serum antibodies against Neospora caninum by a competitive-inhibition enzyme-linked immunosorbent assay and for serum antibodies against Toxoplasma gondii by an indirect fluorescent antibody test. In a total of 925 samples, 280 (30%) and 132 (14%)(More)
Interstitial pneumonia (2/3 of the lungs were affected) and diffusely enlarged bronchial and mediastinal lymph nodes were diagnosed by gross examination of a dead 16-year-old mare. Based on histopathological examination and the detection of acid-fast rods after staining by the Ziehl-Neelsen technique, tuberculosis was suspected. Mycobacterium avium subsp.(More)
The blood serum of game was examined for the presence of antibodies to Leptospiras in 1987-1989. A total of 792 blood sera from animals belonging to 14 zoo-species were examined (Tab. I). The blood serum of red deer (Cervus elephus) was examined the most often within the group of animals, in 398 cases, i.e. 50.2%, followed by 165 blood sera of wild boar(More)
Experimental infections enabled to study susceptibility to M. avium and disease pathogenesis in the turkey and guinea fowl. After intramuscular implantation of M. avium suspension macroscopic tuberculous lesions were observed at the spot of puncture in turkeys in 35 days, and miliary tuberculosis of liver and spleen in 55 days. Cultivation demonstrated(More)
Various species of free living birds play an important role in the epidemiological of avian mycobacteriosis as a source of mycobacteria. Among them of certain importance are feathered game, in this country, particularly pheasant (Phasianus colchicus) and partridge (Perdix perdix). In these species, closer contact with domestic animals can be expected. The(More)
There has recently been a growing interest in checking the state of health of European brown hares in hunting grounds because they are a susceptible bio-indicator of environmental changes and because of the dramatic decline in populations across Europe. A total of 1 051 (384, 302, and 365, respectively) blood sera were collected from hares during autumn(More)
