Heat-labile serotyping of two Campylobacter jejuni strains isolated from patients with Guillain-Barré syndrome and belonging to serotype O19 (Penner)
Misawa et al. (3) recently reported a PCR-based method for differentiating Campylobacter serotype O19 strains from nonO19 strains. In another study (2), the same investigators used restriction fragment length polymorphism analysis of flaA genes and random amplified polymorphic DNA analysis of C. jejuni strains to conclude that all serotype O19 strains are closely related, regardless of their ge...
متن کاملUse of pcr-rflp of the fla a gene for detection and subtyping of Campylobacter jejuni strains Potentially related to Guillain-barré syndrome, isolated from humans and animals
The objectives of the present study were the subtyping of Campylobacter jejuni subsp. jejuni strains obtained from humans and different animal species using PCR-RFLP, and the detection, by means of the same technique, of strains related to serotype PEN O19:LIO 7, the main C. jejuni serotype linked to Guillain-Barré Syndrome (GBS). Seventy C. jejuni strains isolated from human feces (n=33), prim...
متن کاملPrevalence of cdt Gene in Campylobacter jejuni Strains Isolated from Surface Waters of Rasht, Iran
ABSTRACT Background and Objective: Campylobacters are infectious zoonotic agents, and among the main bacterial causes of gastroenteritis in humans. Studies have shown that Campylobacter jejuni is of the main causes of infection among humans. Detection of these infectious agents in water resources is of great importance for maintaining the health of hu...
متن کاملStructure of the O-polysaccharide of Proteus mirabilis O19 and reclassification of certain Proteus strains that were formerly classified in serogroup O19.
INTRODUCTION Bacteria of the genus Proteus are a common cause of urinary tract infections. The O-polysaccharide chain of their LPS (O-antigen) defines the serological specificity of these bacteria. Based on the immunospecificity of the O-antigens, two species, P. mirabilis and P. vulgaris, were classified into 49 O-serogroups, and more O-serogroups for strains of these species and P. penneri ha...
متن کاملCampylobacter jejuni strains from patients with Guillain-Barré syndrome.
Campylobacter jejuni was isolated from stool cultures from 14 (30%) of 46 patients with Guillain-Barré syndrome and from 6 (1.2%) of 503 healthy persons, and the difference was highly significant (p < 0.0001). In addition, serological evidence of recent C. jejuni infection was found in 5 of 29 patients with negative stool cultures. Therefore, 41% of patients were associated with C. jejuni infec...
