The penicillin allergy is being increasingly recognized as a significant public health problem. Immunological responses to penicillin and other beta-lactam antibiotics are classified as immediate and non-immediate responses. This research aimed to develop an enzyme-linked immunosorbent assay (ELISA) for the detection of the reactive antibody value against penicillin in various species of animals...
East Coast fever (ECF) in cattle is caused by the Apicomplexan protozoan parasite Theileria parva , transmitted three-host tick Rhipicephalus appendiculatus . The African buffalo ( Syncerus caffer ) natural host for T. but does not suffer disease, whereas ECF often fatal cattle. genetic relationship between populations circulating and poorly understood, has been studied sympatric This study aim...
Seminal plasma is complex fluid containing a wide variety of both organic and inorganic components, among which proteins are an important part of the high-molecular-weight substances. The protein composition of mammalian seminal plasma varies in species and has important effect on sperm functions such as sperm motility (Henricks et al., 1998), viability (Brandon et al., 1999) and freezability (...
Over a decade ago, foot-and-mouth disease (FMD) re-emerged in Southern Africa specifically in beef exporting countries that had successfully maintained disease-free areas in the past. FMD virus (FMDV) serotype SAT2 has been responsible for a majority of these outbreaks. Epidemiological studies have revealed the importance of the African buffalo as the major wildlife FMD reservoir in the region....
backgrounds: uterine infection is a amajor problem in reproductive management. objectives: the aim of this study was to find out the common pathological condition of cattle and buffaloes' uteri in the ahwaz region and, also to compare uterilesions. methods: one hundred and thirty eight cattle and 101 buffalo uteri were examined for macroscopic lesions, opening them through the cervix to the ape...
The authors estimated the rates of development of serum antibodies against Brucella abortus, between January 1987 and December 1990, in female Jersey cattle and buffalo weaned from seropositive and seronegative dams, and used logistic regression analysis to examine the epidemiological relationship of these rates with the serum antibody status of dams. The offspring from both seropositive and se...
Adipose tissue in the loin muscle area of beef cattle as a marbling factor is directly associated with beef quality. To elucidate whether properties of proteins involved in depot specific adipose tissue were sex-dependent, we analyzed protein expression of intramuscular adipose tissue (IMAT) and omental adipose tissue (OMAT) from Hanwoo cows, steers, and bulls of Korean native beef cattle by li...
The tribe Bovini comprises cattle and cattle-like species. Reconstructions of their phylogeny have so far been incomplete and have yielded conflicting conclusions about the relationship of American bison and wisent (European bison). We have compared the sequences of three mitochondrial and two Y-chromosomal DNA segments. Mitochondrial DNA indicates that four distinct maternal lineages diverged ...
Cystic echinococcosis (CE), caused by the larval stages of the tapeworm Echinococcus granulosus, is known to be one of the most important parasitic infection in livestock worldwide and one of the most widespread zoonoses known. In the present study, we used a geographical information system (GIS) to study the spatial structure of livestock (cattle, water buffaloes and sheep) populations to gain...
