Primary infection by herpes simplex virus type 1 (HSV-1) can cause clinical symptoms in the peripheral and central nervous system, upper respiratory tract, and gastrointestinal tract. Recurrent ocular shedding leads to corneal scarring that can progress to vision loss. Consequently, HSV-1 is the leading cause of corneal blindness due to an infectious agent. Bovine herpesvirus 1 (BHV-1) has simi...

The physiological and production effects of feeding additional vitamin E and ruminally protected vitamin C were examined in cattle challenged with bovine herpesvirus 1 (BHV 1). Forty-eight individually penned 6-mo-old Angus and Angus crossbred heifer calves with a mean BW of 151 kg were allocated randomly to four diets in a 2 x 2 factorial arrangement of treatments. Pelleted diets provided eith...

Abortion in dairy cattle is generally defined as the loss of fetus on days 47-265 of pregnancy and can significantly reduce the income and capital gain of farmers and producers. Therefore, sufficient economical support and preventive measurements are essential for this issue. In this study, genetic materials were extracted from the abomasum rennet, as well as homogenous preparations of brain, k...

Bovine respiratory disease complex (BRDC) is the major cause of serious respiratory tract infections in calves. The disease is multifactorial, with either stress or reduced immunity allowing several pathogens to emerge. We investigated the susceptibility of bovine airway epithelial cells (BAEC) to infection by the three major viruses associated with the BRDC: bovine respiratory syncytial virus ...

In this study, detection of BHV-1 infections in cattle by using polymerase chain reaction (PCR) and enzyme-linked immunosorbent assay (ELISA) investigation the risk factors associated with spread virus within herd were aimed. Three dairy farms selected Thrace district, Marmara region, Turkey, two visits to these farms. A questionnaire was prepared for farmers. On first visit, 4 (14.81%) 27 anim...

to investigate the xenoreactive immune response directed at Galα1, 3-Galβ1-4GlcNAc-R (α-Gal) which is known to be a major barrier in xenotransplantation, and to identify factors such as age, gender, ABO group and type of implanted tissue that might affect the anti-α-Gal immune response in adults subjected to bioprosthetic heart valve (BHV) implantation. Methods: A total of 103 early survivors a...

Calcification (CALC) is the most frequent cause of the clinical failure of bioprosthetic valves (BHV's). Controlled-release (paravalvar) administration of the anticalcification agent ethanehydroxydiphosphonate (EHDP), as either Na 2 EHDP or in combination (1 : 1) with the less soluble CaEHDP, from a silicone rubber matrix (20% w/w EHDP) was studied both in vitro and in vivo for the prevention o...

A study was conducted to determine the prevalence of bovine herpesvirus-1 (BHV-1), which causes infectious bovine rhinotracheitis, in cattle destined for market in Southern Province, Zambia. A total of 116 nasal secretion samples were tested using the direct fluorescent antibody test, while blood samples from the same cattle were examined by a commercial enzyme-linked immunosorbent assay kit. T...
