Glucose-nonfermenting gram-negative bacilli (NFB) have been recognized recently as opportunistic pathogens of humans. With few exceptions, strains of NFB have not been considered important enough to be identified when isolated from animals. In this study, all NFB isolated during a 1-year period in a clinical veterinary microbiology laboratory were identified to determine their prevalence. Of th...

Bordetella hinzii is a Gram-negative bacterium known to infect poultry, humans, rabbits, and rodents. It is an opportunistic pathogen in immunocompromised humans, and some strains cause mild to moderate respiratory disease in turkeys. Little is known as to the degree of genetic diversity within the species or the genetic basis for virulence. Here, we report the genome sequences of six isolates ...

Cell surface proteins of phase I cultures of Bordetella bronchiseptica strains from various species of animals were compared with those of isogenic phase III cultures by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. A protein band with a molecular mass of 74 kilodaltons was found only in various phase I cultures. This protein disappeared in parallel with antigenic modulation and ha...

Pertussis is a respiratory infection that severely affects humans, caused by bacteria of the genus Bordetella, especially species B. pertussis and parapertussis, presenting an important cause infant morbidity mortality. This disease has received little attention from government authorities over years, which can to re-emerge in future. study aimed carry out systematic literature review on epidem...

In nmany species of Granm-negative bacteria one of the surface components of the bacterial cell is a material composed of polysaccharide, protein and phospholipid residues (Boivin, Mesrobeanu & Mesrobeanu, 1933; Morgan, 1937, 1949; Miles & Pirie, 1939 a; Morgan & Partridge, 1940, 1941, 1942; Freeman, 1943; Davies, Morgan & Mosimann, 1954). These substances are antigenic, toxic and pyrogenic and...

bordetella pertussis is a gram negative bacterium that causes respiratory tract infection in human (whooping cough). pertussis toxin (pt) is the main component of current acellular pertussis vaccine and the s1 (subunit1) is the main immunogenic part of it. thus, s1 has been the target of many studies as a potent candidate of acellular vaccine against bordetella pertussis, lacking the side effec...

results among the specimens, 11 cases (1.4%) were culture-positive. among these isolates, only two isolates had high mic values for erythromycin and clarithromycin. pulsed-field gel electrophoresis analysis of the isolates revealed 6 pfge profiles (a-f) among which three and two isolates had the same patterns in profiles a and b, respectively. conclusions azithromycin can be a good drug of choi...
