Differentiation of Neisseria gonorrhoeae isolates requiring proline, citrulline, and uracil by plasmid content, serotyping, and pulsed-field gel electrophoresis.

چکیده
A combination of DNA macrorestriction analysis using pulsed-field gel electrophoresis and a serotyping method using three panels of monoclonal antibody was used to discriminate 43 epidemiologically unrelated Neisseria gonorrhoeae isolates requiring proline, citrulline, and uracil (PCU-) into 35 groups. This indicates that PCU- isolates of N. gonorrhoeae are not clonal.

One hundred and thirty eight penicillinase producing Neisseria gonorrhoeae (PPNG) and 239 non-PPNG strains were characterised serologically using a panel of seven monoclonal antibodies directed against protein 1A and seven against protein 1B. An association between serovar and susceptibility to antimicrobial agents, auxotype, and plasmid content was observed. Serogroup WI strains were more sens...

A panel of 18 strains of Neisseria gonorrhoeae, known to be temporally and geographically diverse, was used to evaluate a number of typing systems, including conventional auxotyping and serotyping and the molecular methods of arbitrarily primed PCR (AP-PCR), amplified ribosomal-DNA restriction analysis (ARDRA), opa typing, and pulsed-field gel electrophoresis (PFGE). The discriminatory power of...

Thirty three penicillinase producing Neisseria gonorrhoeae (PPNG) and 152 non-PPNG strains were serologically classified in relation to their patterns of resistance to antimicrobials, nutritional requirements (auxotypes), and plasmid contents. Of the 185 strains, 65 (35%) belonged to the WI and 120 (65%) to the WII/III serogroup, the predominant serovars of which were Arost and Bropt, respectiv...

Salmonella infections are the second leading cause of zoonotic bacterial foodborne illness. Main source of infection in human is contaminated food products. The aim of this study was sub typing isolates of Salmonella entericaobtained during our previous study byPulsed Field Gel Electrophoresis (PFGE) technique. All 46 Salmonella isolates were serotyped and then subjected to PFGE. Total isolates...
