Subclinical infection of chicken anemia virus (CAV) at 4 to 6 weeks of age, after maternal antibodies have waned, is implicated in several field problems in broiler flocks. In order to understand the pathogenesis of subclinical infection with CAV, an immunopathological study of CAV-inoculated 4-week-old SPF chickens was performed. Sixty 4-week-old SPF(More)
Bioactive peptides such as bradykinin potentiating factor (BPF), have, anti-oxidative, anti-inflammatory, immunomodulatory and ameliorative effects in chronic diseases and play a potential role in cancer prevention. It is known that the liver and kidney accumulate inorganic mercury upon exposure, which often leads to mercury intoxication in these organs. In(More)
Lead is a heavy toxic metal widely distributed in the environment. Lead exposure in Egypt remains a health challenge among children and among traffic controllers, and is manifested by anemia and poor performance. Recently, natural herbs are believed to protect the body against lead-induced hepato- and nephrotoxicity. Garlic extract, calcium carbonate, and(More)
A three-and-a-half year-old female Rahmani ewe was presented suffering from nervous symptoms. Grossly, a large cyst measuring 7 × 4 cm and weighing 145 g occupied the dilated left lateral ventricle. The overlying cerebral tissue was thin, atrophied and congested. It tore easily, and the cyst was evacuated spontaneously. Microscopically, liquefactive(More)
We investigated the immunomodulatory and parasiticidal effects of garlic extract on coccidiosis caused by Eimeria vermiformis infection in male ICR mice. One group received garlic extract daily until the end of the experiment by the oral route from 10 days prior to oral infection with 300 sporulated E. vermiformis oocysts (infected-garlic+). The other group(More)
Chicken anaemia virus (CAV) is the most important confounding pathogen in Marek's disease virus (MDV) infection. The effect of CAV co-infection at 4 weeks of age after inoculation of virulent MDV (vMDV, KS strain) or very virulent MDV (vvMDV, Md/5 strain) in 1-day-old chicks was investigated by pathological and immunohistochemical studies. CAV increased the(More)
The pathogenesis of the co-infection of CAV to MDV is complicated. In order to investigate the impact of CAV on the transformation phase of MD, MDV and, subsequently, CAV, were inoculated at 1day and 4weeks of age, respectively. Chickens were divided into six groups; vvMDV, vvMDV-CAV, vMDV, vMDV-CAV, CAV and a control group. The CAV inclusions and antigens(More)
INTRODUCTION To determine seroprevalence and risks factors for T. gondii in women with early miscarriage, Sera of 76 women were analyzed infection by indirect enzyme linked immunosorbent assay (ELISA). Seropositive cases were further examined histopathologically for evidence of Toxoplasma gondii organisms. MATERIAL AND METHODS Demographic data were(More)
Recently, excessive losses from Marek's disease (MD) have been noted in adult laying flocks over the age of 40 weeks. We defined these late outbreaks in adult chickens as "late MD", and experimentally reproduced the disease in adult SPF P2 line (50-week-old) or commercial line (74-week-old) chickens inoculated with a virulent strain of Marek's disease virus(More)
Pregnant rats were infected experimentally with equine herpesvirus (EHV)-9, a new neurotropic equine herpesvirus serologically similar to EHV-1, during the first and third trimesters. The inoculated dams had mild to severe neurological signs and gave birth to dead fetuses or undersized pups. Rats inoculated during the first and last trimesters had varying(More)
