We sequenced 13 Neisseria gonorrhoeae isolates exhibiting distinct susceptibility profiles and which were recovered over 12 years in the metropolitan region of São Paulo, Brazil. Whole Genome Sequencing (WGS) was performed on an Illumina MiSeq™ 2 × 300 bp paired-end reads. Bioinformatics analyses were carried out using CGE, PATRIC, and BLAST databases for manual curation of obtained genomes. Multilocus sequence typing (MLST) analysis identified seven STs, namely ST1580, ST1590, ST1901, ST1902, ST8161, ST9363, and ST15640. Moreover, a diversity of mutations was observed in MtrR/G45D-A39T, PIB/G120K-A121S, and PBP1/L421P. Mutations associated with sulfonamides (DHPS/R228S) and rifampicin (RNAP/H552N) were also detected, as well as tetracycline resistance determinants, namely rpsJ/V57M and tet(M). The results presented herein can contribute to the knowledge of N. gonorrhoeae strains circulating in Sao Paulo, Brazil.

Background: The Gonococcal Isolate Surveillance Project (GISP) was established to monitor antimicrobial resistance (AR) in N. gonorrhoeae in the United States. Isolates collected in GISP undergo antimicrobial susceptibility testing allowing for estimates of resistance, based on exceeding minimum inhibitory concentrations (MICs), to be calculated.

A 28-year-old man was diagnosed with chlamydial urethritis by his previous doctor and was prescribed minocycline (MINO). The result of a urinary chlamydia polymerase chain reaction (PCR) test later confirmed to be negative. However, the patient visited our hospital because of persistent miction pain.

: Culture-negative vertebral osteomyelitis presents a significant diagnostic challenge. () is a typically benign commensal organism of the upper respiratory tract that rarely causes invasive infections, warranting cautious interpretation if isolated in a single positive culture. This case study details a 62-year-old male diagnosed with vertebral osteomyelitis caused by , examining diagnostic challenges, treatment, and outcomes.

Objectives: Antimicrobial resistance (AMR) in Neisseria gonorrhoeae is compromising gonorrhoea treatment, and enhanced N. gonorrhoeae AMR and genome-based epidemiological surveillance is imperative. Molecular tests are replacing N.
