Identification of Neisseria gonorrhoeae isolates with a recombinant porA gene in Scotland, United Kingdom, 2010 to 2011.
Three isolates of Neisseria gonorrhoeae have been identified in Scotland in 2010 and 2011, which lack sequences in the porA pseudogene commonly used as the target for confirmatory gonorrhoea polymerase chain reaction assays. Two isolates were clustered temporally and geographically and have the same sequence type and porA sequence. A similar strain was reported in Australia during early 2011. T...
متن کاملCephalosporin susceptibility among Neisseria gonorrhoeae isolates--United States, 2000-2010.
Neisseria gonorrhoeae is a major cause of pelvic inflammatory disease, ectopic pregnancy, and infertility, and it can facilitate human immunodeficiency virus (HIV) transmission. Emergence of gonococcal resistance to penicillin and tetracycline occurred during the 1970s and became widespread during the early 1980s. More recently, resistance to fluoroquinolones developed. Resistance was documente...
متن کاملIdentification of novel mutation patterns in the parC gene of ciprofloxacin-resistant isolates of Neisseria gonorrhoeae.
Of 65 ciprofloxacin-resistant, clinical isolates of Neisseria gonorrhoeae, 5 isolates exhibited ParC mutations previously undescribed in the gonococcus. For isolates containing two ParC mutations (the Ser-87-->Ile and Glu-91-->Gly mutations and the Gly-85-->Cys and Arg116-->Leu mutations) the MICs of ciprofloxacin (8.0 to 64.0 microg/ml) were higher than those for the isolate containing the sin...
متن کاملNeisseria meningitidis porA, fetA and fHbp gene distribution in Western Australia 2000 to 2011
BACKGROUND PorA, fetA and fHbp are three antigen encoding genes useful for meningococcal typing and FHbp is an important component of meningococcal B vaccines. METHODS We performed sequence analysis of meningococcal porA, fetA and fHbp genes on 128 isolates from Western Australia, relating results to age, gender, race and geographic region. RESULTS We found predominantly PorA subtypes P1.22...
متن کاملFalse-negative results using Neisseria gonorrhoeae porA pseudogene PCR - a clinical gonococcal isolate with an N. meningitidis porA sequence, Australia, March 2011.
The gonococcal porA pseudogene is a popular target for in-house Neisseria gonorrhoeae PCR methods. With this study we present two novel findings: the first case of an N. gonorrhoeae porA pseudogene PCR false-negative result caused by sequence variation, and in the same organism, the first description of a clinical N. gonorrhoeae strain harbouring an N. meningitidis porA sequence.
