Emerging presence of urethritis and balanitis by Pasteurella bettyae Rosales-Castillo, Antonio Hidalgo Tenorio, Carmen Navarro Marí, José María Gutiérrez Fernández, José Emerging infection Genital infection Men who have sex men diseases Pasteurella bettyae Abstract Background: Humans can also be infrequent infected by Pasteurella bettyae. We report the first association of P. bettyae with urethritis and balanitis in men who have sex with men practicing unprotected intercourse. Patients and methods: The standard culture for bacteria and fungi in genital samples, and a PCR study for Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis, Mycoplasma spp. and Ureaplasma spp, were performed. Cultured microorganisms were identified by Maldi-Tof mass spectrometry and the susceptibility of the isolates were evaluated with the gradient test. Results: P. bettyae were isolated and were found to be susceptible to penicillin, amoxicillin-clavulanic acid, trimethoprim-sulfamethoxazole, ciprofloxacin, and doxycycline. Conclusion: This novel finding highlights the need for complete microbiological screening in adequate samples to detect possible infectious agents in these cases, not limited to conventional agents. These rare microorganisms can be detected by the application of Maldi-Tof in colonies grown in culture media. 2024-07-08T11:03:57Z 2024-07-08T11:03:57Z 2021-08 journal article Rosales-Castillo A, Hidalgo-Tenorio C, Navarro-Marí JM, Gutiérrez-Fernández J.
