Whole cell hydrolysates of Bordetella avium, B. bronchiseptica, B. pertussis, B. parapertussis, Alcaligenes faecalis, A. xylosoxidans ssp. denitrificans, A. xylosoxidans ssp. xylosoxidans, and A. piechaudii were analysed for their cellular carbohydrates by capillary gas-chromatography of per-acetylated aldononitriles and O-methyloximes, respectively. All Alcaligenaceae species could be discriminated on the basis of their carbohydrate profiles and a few conventional features. Taxometric evaluation of the established carbohydrate patterns confirmed previous separation of the taxa and the genetic relatedness within the Alcaligenaceae. One of the advantages of the method is, that the analysis is easy to perform and can be completed within less than 5 h, starting from a pure culture and, therefore, it seems to be applicable as a rapid method in routine diagnostics.

Bacteria can change morphology in response to stressors and changes in their environment, including infection of a host. We previously identified the bacterial species, , which uses nutrient-induced filamentation as a novel mechanism for cell-to-cell spreading in the intestinal epithelial cells of a nematode host. To further investigate the conservation of nutrient-induced filamentation in Bordetellae, we utilized the turkey-infecting species which filaments in vitro when switched from a standard growth media to an enriched media.

An increasing number of reports have described the pathogenic nature of several non-classical spp. Among them, and have been implicated in a myriad of respiratory-associated infections in humans and animals. We report the isolation of a genetically close relative of and from the sputum of a woman in her early 60s with extensive bronchiectasis who presented with fever and brown colored sputum.

Bordetella avium causes a highly infectious upper respiratory tract disease in turkeys and other poultry with high economic losses. Considering the antimicrobial resistance crisis, bacteriophages (phages) may be an alternative approach for treating bacterial infections such as bordetellosis. Here, we describe seven phages, isolated from drinking water and feces from chicken and turkey farms.

Many pathogens that cause chronic diseases in birds use the respiratory tract as a primary route of infection, and respiratory disorders are the main leading source of financial losses in the poultry business. Respiratory infections are a serious problem facing the poultry sector, causing severe economic losses. Avian influenza virus, Newcastle disease virus, infectious bronchitis virus, and avian pneumovirus are particularly serious viral respiratory pathogens.

Introduction: (ORT) causes significant economic losses to the poultry industry around the world. The bacterium often affects poultry as part of multiple infections causing very serious clinical signs that are usually not limited only to the respiratory system. This study's main objective was the retrospective detection and identification of ORT in turkey flocks.
