one hundred sixty two domestic fowls were examined for toxoplasma infection by both indirect haemagglutination tests for toxoplasma antibodies and inoculation of their brains intraperitoneally into mice for the parasite. the overall sero-positive rate (spr) was 29 percent with the titers ranging from 1:20 to 1:6400. the number of each species tested and their spr were: 74 hens (27.0%), 35 roost...

INTRODUCTION The practice of backyard poultry is a very common practice in many homes in Nigeria. Birds raised at home are usually free ranged, which increases close contact between man and birds, thus increasing the risk of transmission of avian influenza virus to man. This study investigated the awareness of bird flu infection and identifies risk factors associated with the practice of backya...

Avian intestinal spirochaetosis (AIS) is a condition arising from colonization of the caeca and colon of birds with anaerobic spirochaetes of the genus Brchyspira. The purpose of the present study was to evaluate PCR amplification from formalin-fixed, paraffin-embedded tissue method for detecting infected laying hens with Brachyspira pilosicoli  with the same primers that have been used for det...

Hepatitis E virus (HEV), the causative agent of hepatitis E, has been reported in a wide variety of animals, including birds, but little is known of HEV infection in pet birds in northwest China. The objective of the present investigation was to examine HEV seroprevalence in three species of pet birds, namely, Eurasian siskin, Oriental skylark, and black-tailed grosbeak from Gansu. Serum sample...

A DNA vaccine for West Nile virus (WNV) was evaluated to determine whether its use could protect fish crows (Corvus ossifragus) from fatal WNV infection. Captured adult crows were given 0.5 mg of the DNA vaccine either orally or by intramuscular (IM) inoculation; control crows were inoculated or orally exposed to a placebo. After 6 weeks, crows were challenged subcutaneously with 105 plaque-for...

This study of infection of southern Australian land snails with Brachylaima cribbi metacercariae has shown that all commonly encountered native and introduced snails are susceptible second intermediate hosts. The range of infected snails is extensive with metacercariae-infected snails being present in all districts across southern Australia. C. virgata has the highest average natural metacercar...

Avian pathogenic Escherichia coli (APEC) can cause significant morbidity in chickens. The thymus provides the essential environment for T cell development; however, the thymus transcriptome has not been examined for gene expression in response to APEC infection. An improved understanding of the host genomic response to APEC infection could inform future breeding programs for disease resistance ...

Newcastle disease (ND) is a highly contagious infection of many avian species, mainly chickens and turkeys, with a devastating impact on worldwide poultry production. The ND accounts for heavy losses in Iranian poultry flocks. There are some reports regarding the epidemiology of this infection in Iran. This study was performed to investigate the infection of turkeys with a Newcastle disea...

background pet birds may carry human infectious agents and some of these can be transmitted to people. campylobacter bacteria are the most common bacteria that cause gastroenteritis worldwide. considering people's interests to keep pet birds and the potential ability of pet birds to transmit campylobacter to humans, the present study was conducted to evaluate campylobacter infection in shahreko...

Clinical respiratory illness was compared in five homozygous chicken lines, originating from homozygous B2, B8, B12 and B19, and heterozygous B2/B12 birds after infection with either of two strains of the infectious bronchitis virus (IBV). All chickens used in these studies originated from White Leghorn and Ancona linages. IBV Gray strain infection of MHC homozygous B12 and B19 haplotype chicks...
