Brachyspira pilosicoli-induced avian intestinal spirochaetosis
Avian intestinal spirochaetosis (AIS) is a common disease occurring in poultry that can be caused by Brachyspira pilosicoli, a Gram-negative bacterium of the order Spirochaetes. During AIS, this opportunistic pathogen colonises the lower gastrointestinal (GI) tract of poultry (principally, the ileum, caeca, and colon), which can cause symptoms such as diarrhoea, reduced growth rate, and reduced...
متن کاملPenicillin-binding proteins in the pathogenic intestinal spirochete Brachyspira pilosicoli.
Penicillin-binding proteins (PBPs) of slightly different molecular masses (94, 62 or 68, 42 or 50, 25, and 22 kDa) were identified in one human and two porcine Brachyspira pilosicoli strains. Identification of PBPs of B. pilosicoli provides a basis for characterization of the genes encoding these proteins among pathogenic intestinal spirochetes of humans and animals.
متن کاملEvaluation of recombinant proteins of Neospora caninum as vaccine candidates (in a mouse model).
Abortion, resulting from infections by the parasite Neospora caninum, is a major cause of economic loss to both the dairy and beef industries of cattle-producing countries of the world. Vaccination as a means of preventing abortion and/or infection represents a viable control strategy; indeed a commercial vaccine is available in some countries, albeit of unknown efficacy. The commercial vaccine...
متن کاملTreatment of a field case of avian intestinal spirochaetosis caused by Brachyspira pilosicoli with tiamulin.
There has been much confusion over the significance of spirochaetes found in the caeca of laying hens and the impact they may have on egg production. In recent years, the situation has been made clearer and the presence of such species as Brachyspira pilosicoli have been shown to cause a mild, chronic disease in both layers and breeders and to reduce egg production by reportedly 5%. In the Unit...
متن کاملImmunomagnetic separation of the intestinal spirochaetes Brachyspira pilosicoli and Brachyspira hyodysenteriae from porcine faeces.
Porcine intestinal spirochaetes are fastidious anaerobic organisms and, as a consequence, it has been necessary to develop various protocols to enhance their isolation from or detection in faeces. Immunomagnetic separation (IMS) is a method developed recently to improve separation of target cells from mixed cell suspensions. The purpose of the present study was to compare the relative sensitivi...
