The elimination of tuberculosis (TB) among cattle was claimed in Czecho-Slovakia in the middle of the sixties. Experiences from some countries which eliminated TB among cattle earlier than Czecho-Slovakia indicated a sporadic occurrence of TB caused by M. bovis. A long-term investigation of the occurrence of this 'diminishing zoonosis' has been carried out by a special group of experts (epidemiologists, clinicians, bacteriologists, epizootiologists and veterinary surgeons) on the whole territory of Slovakia. During the period of years 1972-1990 there were discovered 68 new cases of TB in humans caused by M. bovis. This paper analyses the results of the epidemiological investigation of this group of patients from several aspects: eg age, sex, occupation and geographical distribution.

are ubiquitous algae and occasional pathogens of humans and animals. While rare, the infection is often fatal and treatment options are limited to antifungals with low efficiency. Here, using growth curve assays, we demonstrate that five pathogenic species of () were fully inhibited by 50-100 μg/mL of herbicide glyphosate, suggesting novel pathways that can be considered for anti-algal drug development.

The domestic dog () is a competent host for () infection but no ante mortem diagnostic tests have been fully validated for this species. The aim of this study was to compare the performance of ante mortem diagnostic tests across samples collected from dogs considered to be at a high or low risk of sub-clinical infection. We previously tested a total of 164 dogs at a high risk of infection and here test 42 dogs at a low risk of infection and 77 presumed uninfected dogs with a combination of cell-based and/or serological diagnostic assays previously described for use in non-canid species.

Mycobacterial infections are an important emerging zoonosis in companion animals for which diagnostic options remain imperfect, and the canine immunological response to these infections has been poorly investigated. We sought to further define the cellular response of peripheral blood mononuclear cells (PBMCs) from dogs infected with , as determined using a commercial interferon-gamma response assay (IGRA). To this end, PBMCs from healthy or infected dogs were collected.

Bartonellae are zoonotic pathogens with a broad range of reservoir hosts and vectors. To examine sylvatic reservoirs, tissue samples of red deer (, = 114) and their associated deer keds (, = 50; , = 272) collected in the Czech Republic were tested for the presence of using PCR at four loci (, , , ITS); PCR sensitivity was increased significantly by using primers modified for the detection of wildlife-associated bartonellae. One-third of the deer and 70% of the deer keds were positive; within the tested animal tissues, usually the spleen was positive.
