BACKGROUND Tuberculosis (TB) is the leading cause of death worldwide from a single infectious agent. An ability to detect the Mycobacterium tuberculosis complex (MTC) in clinical material while simultaneously differentiating its members is considered important. This allows for the gathering of epidemiological information pertaining to the prevalence, transmission and geographical distribution o...

BACKGROUND After 15 years of absence, in 2013 bovine tuberculosis (bTB), caused by Mycobacterium (M.) bovis and M. caprae, reemerged in the Swiss dairy cattle population. In order to identify the sources of infection as well as the spread of the agents, molecular-epidemiologic tracing by MIRU-VNTR analysis in combination with spoligotyping was performed. A total of 17 M. bovis and 7 M. caprae i...

Bovine besnoitiosis is considered an emerging chronic and debilitating disease in Europe. Many infections remain subclinical, and the only sign of disease is the presence of parasitic cysts in the sclera and conjunctiva. Serological tests are useful for detecting asymptomatic cattle/sub-clinical infections for control purposes, as there are no effective drugs or vaccines. For this purpose, diag...

The apicomplexan parasite Besnoitia besnoiti is the causative agent of bovine besnoitiosis that affects livestock, particularly cattle. The definitive host of B. besnoiti is unknown and its transmission only partially understood. Here, we report the first draft genome sequence, assembly, and annotation of this parasite.

Besnoitia darlingi and Besnoitia neotomofelis are cyst-forming tissue apicomplexan parasites that use domestic cats (Felis domesticus) as definitive hosts and opossums (Didelphis virginiana ) and Southern Plains woodrats (Neotoma micropus) as intermediate hosts, respectively. Nothing is known about the prevalence of B. darlingi or B. neotomofelis in cats from the United States. Besnoitia darlin...

A survey of 143 hunter-harvested red deer for tuberculosis was conducted in an Alpine area in Western Austria over two subsequent years. There, single tuberculosis cases caused by Mycobacterium caprae had been detected in cattle and red deer over the preceding decade. The area under investigation covered approximately 500 km(2), divided into five different hunting plots. Lymph nodes of red deer...

A study was conducted to optimise a multiplex serological immunoassay for use in identification of goats infected with Mycobacterium bovis. To assess assay specificity, 31 goats with a history of being free from M. bovis infection were used. To determine assay sensitivity, 180 Single Intradermal Comparative Tuberculin test (SICTT) positive goats were recruited. Additionally, 286 SICTT negative ...

Specific chewing lice from European bison and some selected species of common European ungulate mammals – cattle, horses, goats, roe deer, red deer, were examined. The faunistic research was on four species of chewing lice, including Bisonicola sedecimdecembrii from European bison (prevalence – 46%, mean intensity – 11 specimens), Bovicola bovis from cattle (29%, 5), Bovicola caprae from goat (...

Sixty-one isolates of M. bovis (58 from cattle and three from wild animals) from eight regions of Poland were analysed. Molecular analysis was done using HAIN and spoligotyping methods. Drug susceptibility of the isolates to streptomycin, izoniazid, rifampicin, ethambutol, and pyrazinamide was tested by proportional methods on solid and liquid media. By spoligotyping, 47 (77%) isolates were ide...

Lice have been described on goats in commercial farming systems in South Africa but not from flocks on communal grazing. During a longitudinal survey on the causes of goat kid mortality, conducted in Jericho district, North West Province, lice were collected from communally grazed indigenous goats. These lice were prepared for and viewed by scanning electron microscopy, and micro-morphological ...
