Isolation of Actinobacillus lignieresii and Actinobacillus equuli from laboratory rodents.
Actinobacillus lignieresii and Actinobacillus equuli were cultured from a total of 36 guinea pigs, rats, and mice. The organisms were isolated from the oropharynx, the conjunctiva, and middle ear. Isolates were initially screened by eight biochemical tests to determine whether they were of the genus Actinobacillus. Actinobacillus spp. were then differentiated by fermentation reactions of nine c...
متن کاملGenetic diversity of Actinobacillus lignieresii isolates from different hosts
Genetic diversity detected by analysis of amplified fragment length polymorphisms (AFLPs) of 54 Actinobacillus lignieresii isolates from different hosts and geographic localities is described. On the basis of variances in AFLP profiles, the strains were grouped in two major clusters; one comprising strains isolated from horses and infected wounds of humans bitten by horses and another consistin...
متن کاملBacteriological and serological studies on Mannheimia haemolytica infection in cattle slaughtered at Ahvaz (southwestern Iran) abattoir
In order to investigate the prevalence of Mannheimia haemolytica infection in cattle, nasal andnasopharyngeal swabs and blood samples were obtained from 250 cattle after slaughter at Ahvaz(southwestern Iran) abattoir. Nasal and nasopharyngeal swabs were cultured on blood agar and incubated at37°C for 24-48 h. The suspected bacterial cultures were processed for isolation of M. haemolytica follow...
متن کاملSerological characterisation of Actinobacillus pleuropneumoniae
In the most recent study on the serological characterisation of Australian isolates of A pleuropneumoniae, a large percentage of isolates either gave cross-reactions with serovars 3 and 6 (47/256 isolates) or no reaction at all (91/256 isolates).11 This study was performed using slide agglutination and GD, techniques which had performed effectively in the past.5 The high incidence of isolates t...
