It appears interesting to write on Mycobacterium tuberculosis, primarily pathogen of human tuberculosis (TB) and M. bovis, primarily pathogen of cattle (BTB), other domestic animals and wild life in context of burden of these two closely related species in human and animals. The common notion in the mind of researchers has been their strong believe that M. tuberculosis does not infect cattle vi...

during last two decades studies on endozoochorous seed dispersal indicated that a large numbers of plant seeds are potentially dispersed and suceefully germinated via animal dung. however, very little is known about the relative importance of endozoochory in germination success of plant species in semi-steppe rangelands. in this paper we examined dung germinating seed content, seed deposition p...

Grazing cattle on forest plantations in the interior of British Columbia is a common practice. Soil compaction can occur following cattle use, although this may vary with stocking rate, vegetation type and age, soil type, soil water content, and climate. Several studies have shown that increased soil compaction can have a negative impact on growth of young tree seedlings and on productivity in ...

Recurrent spillover of Brucella abortus from wildlife reservoirs to domestic cattle in the Greater Yellowstone Area (GYA) has prevented the United States from completely eradicating bovine brucellosis. Risks to cattle are a function of the size and location of wildlife and livestock populations, the degree and nature of spatio-temporal interactions between the various hosts, the level of diseas...

Many species are currently undergoing reductions in population size due to widespread habitat loss and expanding human activities. Because interspecific hybridization is often a consequence of population decline and fragmentation, identification of individuals or populations with hybrid ancestry is an increasingly important issue in conservation biology. In many wild cattle and bison species, t...

Interspecific hybrid embryos are useful models for the study of maternal-fetal interactions, transmission pattern of species-specific markers and parental contributions to growth and developmental potential of pre-attachment embryos. In an attempt to investigate the possibility of producing hybrid embryos of domestic cattle (Bos taurus) and water buffalo (Bubalus bubalis), cattle oocytes were e...

Tuberculosis caused by Mycobacterium bovis in domestic livestock and wildlife is a significant problem in many countries worldwide. Wildlife reservoirs of tuberculosis confound programs for tuberculosis eradication from domestic livestock. Successful vaccination against tuberculosis in domestic animals or wildlife could contribute to tuberculosis eradication. Bacille Calmette-Guérin (BCG) has b...

Piroplasmosis caused by different tick-borne hemoprotozoan parasites of the genera Theileria and Babesia is among the most economically important infections of domestic ruminants in sub-Saharan Africa. A survey for piroplasm infection was conducted in three locations in Northern Ethiopia. Of 525 domestic ruminants surveyed, 80% of the cattle, 94% of the sheep and 2% of the goats were positive f...
