N2  - A bacterial isolate was obtained from the uterine discharge of a rhesus macaque suffering from Endometritis and subsequently characterized. On Columbia blood agar incubated at 37 °C for 24 h, the organism formed circular, elevated, gray-white colonies with smooth surfaces, typically 1–2 mm in diameter. When cultured on salmonella–shigella agar (S.S.) under the same conditions, the colonies appeared flat, transparent, and round. Microscopic examination following Gram staining revealed gram-negative, blunt-ended rods lacking spores. Sequencing of the 16S rRNA gene demonstrated more than 96.9% identity with published Morganella morganii sequences listed in GenBank. Integrating morphological and molecular analyses confirmed the isolate (RM2023) from the rhesus monkey’s cervical secretions as M. morganii. Antibiotic susceptibility profiling showed RM2023 was responsive to ceftriaxone, amikacin, gentamicin, cefazolin, cefuroxime, ceftazidime, levofloxacin, cotrimoxazole, norfloxacin, and tetracycline; had intermediate response to ampicillin; and was non-susceptible to penicillin, vancomycin, ciprofloxacin, and clindamycin. These results enhance understanding of infectious diseases in rhesus monkeys and supply useful data for molecular epidemiological work.
