Abstract
Antimicrobial-resistant Neisseria gonorrhoeae (NG) is a global public health issue that threatens effectiveness of current treatments of NG. Increased use of nucleic acid amplification tests (NAATs) in lieu of cultures makes obtaining clinical isolates for susceptibility testing difficult and samples collected in commercial transport buffer for NAATs do not preserve viable organism, while molecular methods of assessing antibiotic susceptibility do not require viable organism. We evaluated 243 NG-positive samples in Aptima transport media including urine, oral, and rectal swabs from Nigerian men who have sex with men for markers to penicillinase-producing NG, ciprofloxacin ( GyrA and ParC mutations), and extended spectrum cephalosporins (ESCs, PenA mosaic [allele X], PonA, mtrR, PorB mutations) by real-time PCR. NG DNA was recovered in 75% (183/243) of samples. Of these, 93% (171/183) were positive for at least one resistance marker. We observed a prevalence of dual resistance markers to penicillin and ciprofloxacin at 46.2% (79/171). Six percent of samples (10/171) tested positive for the PenA mosaic (allele X) ESC marker. These data indicate that antibiotic-resistant NG is common in Nigeria. Laboratory and clinical capacity building in Nigeria should include development of methods to culture NG and determine antimicrobial susceptibility.

Gonococcal sepsis in a 32-year-old female: a case report. BMC Res Notes 2018; 11:253. [PMID: 29690929 PMCID: PMC5916728 DOI: 10.1186/s13104-018-3346-1] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2017] [Accepted: 04/05/2018] [Indexed: 11/10/2022] Open
Abstract
Background Neisseria gonorrhoeae is a Gram-negative bacterium which affects the urethra, throat, rectum and cervix of patients and often associated with sexually transmitted infections. The global epidemiology of the disease is not well characterised especially in resource constraint countries due to poor diagnostic capacity and inefficient reporting systems. Although important, little is known about the propensity of this bacterium to cause sepsis in immunocompetent individuals. Case presentation A 32-year-old female presented with fever and generalised malaise to a rural hospital in Ghana. The patient had previously been diagnosed as having enteric fever from a neighbouring health facility. Blood and urine samples were collected from the patient and cultured using standard microbiological and molecular techniques. Neisseria gonorrhoeae was isolated from the blood which was resistant to penicillin, ciprofloxacin and cotrimoxazole. The patient recovered following ceftriaxone and azithromycin treatment. Conclusion This case highlights the importance of N. gonorrhoeae in causing sepsis and emphasises the need for blood culture investigation in diagnosis of patients presenting with fever.

Presence of Chlamydia trachomatis and Mycoplasma spp., but not Neisseria gonorrhoeae and Treponema pallidum, in women undergoing an infertility evaluation: high prevalence of tetracycline resistance gene tet(M). AMB Express 2017; 7:206. [PMID: 29150724 PMCID: PMC5691826 DOI: 10.1186/s13568-017-0510-2] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2017] [Accepted: 11/11/2017] [Indexed: 01/07/2023] Open
Abstract
Chlamydia trachomatis, Mycoplasma spp., Neisseria gonorrhoeae and Treponema pallidum are sexually transmitted pathogens that threaten reproductive health worldwide. In this study, vaginal swabs obtained from women (n = 133) that attended an infertility clinic in China were tested with qPCRs for C. trachomatis, Mycoplasma spp., N. gonorrhoeae, T. pallidum and tetracycline resistance genes. While none of vaginal swabs were positive for N. gonorrhoeae and T. pallidum, 18.8% (25/133) of the swabs were positive for Chlamydia spp. and 17.3% of the swabs (23/133) were positive for Mycoplasma species. All swabs tested were positive for tetracycline resistance gene tet(M) which is the most effective antibiotic for bacterial sexually transmitted infections. The qPCRs determined that the gene copy number per swab for tet(M) was 7.6 times as high as that of C. trachomatis 23S rRNA, and 14.7 times of Mycoplasma spp. 16S rRNA. In China, most hospitals do not detect C. trachomatis and Mycoplasma spp. in women with sexually transmitted infections and fertility problems. This study strongly suggests that C. trachomatis and Mycoplasma spp. should be routinely tested in women with sexually transmitted infections and infertility in China, and that antimicrobial resistance of these organisms should be monitored. Further studies are warranted to determine the prevalences in different regions and associated risk factors.
