Abstract:
... Six clones of monoclonal antibodies (Mabs) to fowl adenovirus (FAV) serotype 1 were produced. All Mabs reacted positively by enzyme-linked immunosorbent assay. Three Mabs recognized the putative 100-kD hexon protein and reacted to serotype 1 specifically by western blot analysis but did not react to other FAV serotypes (2, 3, 4, 5, 6, 7, and 8a). These Mabs will be useful for immunodiagnosis of FA ...

Abstract:
... Colibacillosis accounts for annual multimillion dollar losses in the poultry industry, and control of this disease is hampered by limited understanding of the virulence mechanisms used by avian pathogenic Escherichia coli (APEC). Previous work in our laboratory has found that the presence of the increased serum survival gene (iss) is strongly associated with APEC but not commensal E. coli, making ...

Abstract:
... Long-term feed withdrawal has been shown to increase ileocecal intestinal colonization and fecal shedding of Salmonella enterica serovar Enteritidis in challenged hens. Less information is available regarding effects of fasting on crop colonization. Two trials were conducted to compare effects of 14-day feed withdrawal vs. full feed on crop colonization in hens challenged with Salmonella Enteritid ...

Abstract:
... Avian polyomavirus (APV) and psittacine beak and feather disease virus (PBFDV) are the most common viral diseases of psittacine birds. In Taiwan, however, the existence of these viruses in psittacine birds has not been established. Polymerase chain reaction (PCR) methodology was therefore employed to ascertain whether APV and PBFDV genomes were present in isolates from psittacine birds of Taiwan. ...

The intestinal tract and intestinal contents were collected from 34 stunted, 5-to-14-day-old broiler chicks from eight flocks with runting and stunting syndrome (RSS) in Northern Germany to investigate intestinal lesions and the presence of enteric pathogens with a special focus on rotaviruses (RVs). Seven chicks from a healthy flock were used as controls. Severe villous atrophy was seen in chicks ...

Four strains of APVs, from chickens, a pigeon, and a turkey, were isolated from cutaneous lesions by inoculation onto the chorioallantoic membranes (CAM) of 12-day-old specific-pathogen-free chicken embryos. The resulting proliferative CAM lesions contained eosinophilic cytoplasmic incl ...

A severe impaction of the lower intestinal tract, because of litter, was found on necropsy in two of three recently dead cockerels. Litter could be seen in the markedly distended vent of the most affected bird. This bird also had feces and litter in the body cavity because of a ruptured small intestine. Both birds h ...

The ability of APEC to cause disease is determined by certain virulence markers, some of which are located on pathogenicity islands (PAIs). We recently described one such PAI in an APEC O1:K1 strain (APEC-O1). This PAI, termed PAI IAPEC-O1, carries the genes of t ...
