microscopy as “field based test” was compared with is900 blood pcr for the diagnosis and estimationof prevalence of mycobacterium avium subspecies paratuberculosis (map) in domestic livestock withclinical johne’s disease (jd). of 252 animals screened, 39.3 and 13.1% were positive by faecal microscopyand blood pcr, respectively. proportional agreement between “microscopy” and blood pcr was subst...

The widespread replacement of wild ungulate herbivores by domestic livestock in African savannas is composed of two interrelated phenomena: (1) loss or reduction in numbers of individual wildlife species or guilds and (2) addition of livestock to the system. Each can have important implications for plant community dynamics. Yet very few studies have experimentally addressed the individual, comb...

introduction & objective: protein is one of the important nutritional groups of which the main source is domesticated animals. parasitic infection of these livestock is a threat to the meat resources as well as trouble to health of the user. so, the infection rate for zoon sis in each region can be an indicator for the health of the people living in that region. concerning the geographical situ...

White-tailed deer (Odocoileus virginianus) experimentally infected with a virulent strain of Mycobacterium bovis have been shown to transmit the bacterium to other deer and cattle (Bos taurus) by sharing of pen waste and feed. The risk of transmission of M. bovis bacille Calmette-Guerin (BCG) vaccine from orally vaccinated white-tailed deer to other deer and cattle, however, is not well underst...

Schistosoma japonicum remains highly endemic in many counties in China and has recently re-emerged, to a large extent, in previously controlled areas. To test the hypothesis that small rodents and less agriculturally important domestic animals such as dogs and cats may play an important role in the transmission and potential re-emergence of this disease, an annual investigation of S. japonicum ...

zoonotic helminths are often transmitted to humans through domestic animals. this retrospective study was performed to estimate the prevalence of some important zoonotic helminthic infections of the liver and lung including echinococcosis, fasciolosis and dicrocoeliasis in kazerun and shiraz abattoirs, fars, iran, during 2011-2013. a total of 12381 sheep, 6473 cattle, 22847 goats, 66 camels, an...

Schistosomiasis japonica, caused by Schistosoma japonicum, is an endemic, zoonotic parasitic disease. Domestic animals, particularly bovines, are thought to play an important role in transmission of the disease. Historically, China was the country mostly severely impacted by schistosomiasis japonica, but now prevalence and morbidity have been greatly reduced. Since the mid-1950s when China laun...

The objective of these experiments was to determine adaptation by ruminants to dietary sulfur. In Exp. 1, lambs (n = 54; BW = 33.6 ± 0.4 kg) were allotted to 3 treatments: 1) 0% added dietary S (0%S), 2) 0.2% added dietary S (0.2%S), or 3) 0.4% added dietary S (0.4%S). Sulfur was added to the diet as Na(2)SO(4). Lambs fed the 0.2%S and 0.4%S diets had greater (P < 0.01) ADG and G:F compared to ...

The cytochrome P450 (P450) superfamily represents a group of relevant enzymes in the field of drug metabolism and several exogenous or constitutional factors contribute to regulate its expression. Cattle represent an important source of animal-derived food-products and studies concerning the P450 expression are needed for the extrapolation of pharmacotoxicological data from one species to anoth...

Tumours of odontogenic origin have been reported in various domestic animals. Ameloblastic fibroodontomais a rare tumour derived from odontogenic epithelium and pulpal mesenchyme. Plain andformalised sections from masses on the front of the cranial aspect of the jaw and the end of the tongue of acastrated beef cattle from an abattoir was submitted to Mt Pleasant laboratories, Launceston, Austra...
