Here we report the results of an investigation into the possibility that one mechanism responsible for the establishment of persistent human immunodeficiency virus infection is an early regulatory T (Treg) cell response that blunts virus- specific responses. Using the simian immunodeficiency virus (SIV)–infected rhesus macaque model, we show that, indeed, viral replication and immune activation in lymphatic tissue drive a premature immunosuppressive response, with dramatic increases in the frequencies of CD4+CD25+FOXP3+ Treg cells, transforming growth factor–β1+ cells, interleukin–10+ cells, and indoleamine 2,3-dioxygenase+CD3+ cells.When we compared SIV infection with rhesus cytomegalovirus (RhCMV) …

Dichelobacter nodosus is an essential causative agent of footrot in ruminants, particularly in sheep, goats and cattle. In this study, more than 100 footrot samples were collected from 4 different farming regions in New Zealand (NZ). Selective media were chosen and isolation and routine growth conditions were optimized for NZ D. nodosus serotypes. Approximately 1000 primary plates were anaerobically subcultured several times and examined with Gram staining in order to detect single colonies of D. nodosus. Both the variable region and a part of the conserved region of fimbrial subunit gene (fimA) were amplified from bacterial DNA using polymerase chain …

This study was conducted to determine the serum Cu, Zn, Se and Fe concentrations at 60, 100, and 150 days of pregnancy and at 45 days of parturition in twin and single pregnant sheep. A total of 30 pregnant Akkaraman sheep in 2 groups (15 single pregnancies, 15 twin pregnancies), aged 3-5 years and weighing 40-50 kg were used. The blood samples were analyzed for serum Cu, Zn, Se and Fe concentrations. No statistically significant difference was found for Se, Cu, Fe and Zn concentrations between the twin and single pregnancy groups. Insignificant decreases (P > 0.05) in serum Zn and …

Effects Of Dietary Fluoride Levels On Growth, Serum Indexes And Antioxidant Systems In Growing Pigs, Xin Tao, Zi Rong Xu, Yi Zhen Wang
Turkish Journal of Veterinary & Animal Sciences
Ninety-six growing pigs were used to evaluate the effects of fluoride levels on growth performance, serum indexes and antioxidant systems. Four dietary treatments were formulated by supplementing fluorine (as NaF) to provide the following added fluorine levels: 0, 50, 100 and 150 mg/kg. The results showed that pigs consuming diets with 100 and 150 mg/kg fluorine added had poor growth performance, and most serum biochemical indexes were significantly altered compared to the control (P < 0.05). On the other hand, serum and liver MDA concentration significantly increased due to the addition of 150 mg/kg fluorine (P < 0.05). T-AOC levels and the activities of SOD, GSH-PX, CAT and GST of serum and liver in fluoride added groups decreased, most of which altered significantly (P < 0.05). These results indicated that excessive fluoride ingestion had an adverse effect on animal health and performance.

Coxiellosis is a zoonosis caused by Coxiella burnetii. This study conducted to determine the prevalence of coxiellosis in cattle and farmers in Eastern Turkey. A total of 230 cattle and 92 human sera were collected and tested for antibodies against C. burnetii by a commercial ELISA kit. The antibodies to C. burnetii were detected in 22 (9.56%) cattle and 18 (19.5%) healthy farmers. Seropositivity was found in 12 of 53 (22.6%) cattle with an abortion history, and 10 of 177 (5.6%) cattle without an abortion history (P < 0.05). There was a correlation between animal and human seroprevalence in the same district. It was observed that the seroprevalence of coxiellosis was higher in northern districts (32.4% in farmers and 15.4% in cattle) than in other districts (12.1% in farmers and 6.5% in cattle) both for humans and animals (P < 0.05). Coxiellosis was an important health problem in both humans and cattle, and the disease may cause abortion in cattle in Eastern Turkey.
