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...

Rapid slide agglutination (RSA), quantitative plate agglutination, slow tube agglutination (STA), and ring precipitation (RP) tests were performed on 200 isolates of Haemophilus pleuropneumoniae by using the type sera produced in rabbits against five known serotype strains and one strain 202. RSA and RP tests both yielded the same results as those by STA. None of the agglutination procedures co...

Multilocus sequence typing (MLST) based on the 16S RNA, pduF, glnA, and manB genes was developed for Salmonella, and its discriminatory ability was compared to those of pulsed-field gel electrophoresis (PFGE) and serotyping. PFGE differentiated several strains undifferentiable by serotyping, and 78 distinct PFGE types were identified among 231 Salmonella isolates grouped into 22 serotypes and 1...

Laboratory detection of specific foot-and-mouth disease virus (FMDV) is routinely carried out by ELISA and RT-PCR. Identification and serotyping of FMDV by ELISA requires polyclonal antibodies raised in rabbits and guinea pigs. The polyclonal antibodies have certain disadvantages such as batch to batch variation, inconsistent yields of antibodies and limited quantity of serum obtained from indi...

BACKGROUND In Burkina Faso dirty water in particular those of the stoppings and the gutter ones are used for vegetables irrigation in the gardens. The aim of this study was to determine the prevalence and antibiotic susceptibility of Salmonella serotypes from humans and lettuce samples inBurkina Faso. Materials and Methods:Salmonella strains isolated from patients in 2009 to 2015 and lettuce sa...

Rapid and accurate detection of Shiga toxin-producing Escherichia coli (STEC) of all serotypes from patients with diarrhea is critical for medical management and for the prevention of ongoing transmission. In this prospective study, we assessed the performance of a multiplex, real-time PCR assay targeting stx1 and stx2 for the detection of O157 and non-O157 STEC in diarrheal stool samples enric...
