Several years lasting clinical and microbiological monitoring of a cattle herd infected with paratuberculosis allowed to identify three groups of animals showing different courses of the infection. Group N (non-shedders) included animals negative by faecal culture throughout the monitoring period. Animals of Group L (low shedders) shed sporadically small quantities of mycobacteria (1 to 9 CFU), but remained clinically healthy throughout the monitoring period. Group H (high shedders) included animals shedding repeatedly large quantities of Mycobacterium avium subsp. paratuberculosis (10 CFU) with a progressive deterioration of the...

The effect of a single oral dose of iodinated fatty acid esters (IFAE) on iodine levels in colostrum and milk of goats was tested. In experimental goats that received a single oral dose of IFAE before delivery, significantly higher iodine levels in milk were recorded 60 days after the delivery. In the following period since day 75 after the delivery iodine levels decreased, however, remained higher compared to the control, e.g. on day 152 the levels were twice as high as in the controls. Based on these results, the effect of a single oral and parenteral application of IFAE was tested on dairy cows. The results of the experiment showed that a single...

Canine coronavirus (CCV) and canine parvovirus type 2 (CPV-2) are the causative agents of gastroenteritis in dogs. Seventy fecal samples from dogs with signs of gastroenteritis (vomiting and diarrhea), twenty-five fecal samples from healthy dogs and one CPV-2 vaccine strain were amplified by semi-nested polymerase chain reaction (PCR) and semi-nested reverse transcriptase polymerase chain reaction (RT-PCR), aimed at specifically studying the gene encoding the most abundant capsid protein VP2 of CPV-2 and spike protein of CCV. The specificity of the CCV RT-PCR product was evaluated by sequencing. Positive specimens comprised 44 samples (62.8%) and 9...

Analyses of ornithological field records, direct observations of typical lesions, and examination by electron microscopy revealed leg papillomatosis in six chaffinches (Fringilla coelebs) in theCzech Republic and one chaffinch inGermany. Papillomavirus was identified by electron microscopy using the negative staining technique in skin lesions of one chaffinch caught in theCzechRepublic. This is the first report of papillomatosis in chaffinches recorded in theCzechRepublic.

Vet Med - Czech, 2003, 48(6):175-176 | DOI: 10.17221/5766-VETMED  

Poisoning with acetylcholinesterase inhibitors in dogs is described. Diagnosis is confirmed by presence of carbofuran, chlorpyrifos and their metabolites in livers of poisoned dogs
