Campylobacter jejuni is a major cause of bacterial food-borne infection in the industrial world. There is evidence that C. jejuni is present in eggs and hatchery fluff, opening the possibility for vertical transmission from hens to progeny. Poultry operations in Iceland provide an excellent opportunity to study this possibility, since breeding flocks are established solely from eggs imported fr...

Background: Caregiving for grandchildren has effect on the physical health of older adults. Physical well-being may also affect the daily activities of grandparent caregivers. Therefore, there may be a reciprocal effect between grandparent caregiving and health. However, few studies have tested this dynamic relationship. This study examined how grandparent caregiving and self-rated health (SRH)...

Broiler chickens aged 40 and 46-days-old from two neighboring flocks belonging to a commercial broiler complex, presenting facial edema, severe respiratory signs and 10% mortality were analyzed. Pneumonic lesions and opaque thoracic and abdominal air sacs with foamy exudate were seen at postmortem examination. Histopathology of lungs showed fibrinoheterophilic pneumonia in both cases. Small pin...

The aim of this study was to determine the presence of genes coding for alpha (cpalpha), beta (cpbeta), epsilon (epsilontx), iota (iotaA), enterotoxin (cpepsilon) and beta2 (cpbeta2) toxins in Clostridium perfringens isolates from broiler chickens and parent broiler breeder hens, using multiplex polymerase chain reaction (PCR) assay. The prevalence of C. perfringens in the intestinal segments a...

The study was conducted to know the rate of maternally derived antibodies (MDAs) transfer from parents to their offspring and declining the MDAs in their chicks at 0, 7, 14, and 21 days of age against four major poultry viruses like Newcastle disease virus (NDV), Infectious bronchitis virus (IBV), Infectious bursal diseases virus (IBDV), and Avian Reo virus (ARV).
