Staphylococcus aureus in commercial breeder layer flocks
Four flocks of Layer breeders, consist of 28000 (7000 birds each) at 25 weeks of age, hatchery and one day old chicks were subjected to swab sampling in order to isolate Staphylococcus aureus during the period from May till June 2008. Results revealed that more than half of the overall swab samples were positive (52.04%). Different isolation rates were recorded between four flocks, ranging from...
متن کاملIntestinal spirochaetes colonizing aborigines from communities in the remote north of Western Australia.
Intestinal spirochaetal bacteria were isolated from 59 of 181 (32.6%) faecal samples obtained from Aboriginal children and a few adults living in communities in the Kimberley region in the north of Western Australia. Colonization was more common in young Aborigines between 2 and 18 years of age than it was in adults, or in babies and children less than 2 years of age. Three of 22 Aboriginal chi...
متن کاملEffects of Egg Size and Eggshell Conductance on Hatchability Traits of Meat and Layer Breeder Flocks
Eggs obtained from 46 and 42 weeks old meat (Hybro) and layer (Leghorn) breeders flocks, respectively were used to examine the effects of genetic type of birds and egg size (small, medium and large) on variables of eggshell characteristics and hatchability traits. The variables measured were egg weight (EW), egg surface area (ESA) and eggshell characteristics (shell conductance (EC), per cent s...
متن کاملPrevalence, Genetic Relationships and Pathogenicity of Intestinal Spirochaetes Infecting Australian Poultry
The prevalence of infection with intestinal spirochaetes in chickens in Western Australia was assessed by selective culture of faecal samples. Colonisation was common, with 35.1% of layer flocks and 53.3% of broiler breeder flocks being positive. Spirochaetes were recovered significantly more frequently from flocks with diarrhoea or reduced production than from clinically normal flocks. The gen...
متن کاملIsolation and characterisation of intestinal spirochaetes.
Faeces or rectal swabs from 1527 subjects were examined for the presence of intestinal spirochaetes by anaerobic culture on blood agar incorporating spectinomycin (400 mg/l). Twenty three specimens (1.5%) were positive, and only one of these came from a patient with diarrhoea. All positive specimens came from either Asians or known homosexuals. Comparative tests showed a close phenotypic simila...
