RESUMEN

BACKGROUND: Salmonella typhi is a specific strain of the Salmonella bacterium, responsible for triggering typhoid fever; a significant public health concern in developing nations. OBJECTIVE: The current study aimed to identify the bacteria from the gallbladder, taken during cholecystectomies of patients, by isolating Salmonella typhi and by using microscopic characteristics, biochemical and polymerase chain reaction (PCR) tests. METHODS: A total of 120 specimens were collected from the Baghdad Teaching Hospital, Iraq. A cross-sectional descriptive study was carried out from October, 2021, to July, 2022. During that study, 26 (54.2%) male patient tested positive for Salmonella typhias well as 22 (45.8%) female patients. The age of the patients varied from < 30 to > 60 years. p-value > 0.05 was considered significant to confirm a relationship between age and Salmonella typhi effect for patients. RESULTS: Out of the 120 blood samples taken for this study, 48 (40%) tested positive by use of PCR test, 40 (33.3%) tested positive by use of the Widal test, 35 (29.1%) were positive for biopsy culture, and 35 (29.1%) were positive for blood culture. All Salmonella typhi isolates were found to be sensitive to the imipenem, cefepime, and ceftriaxone, but were resistant to gentamycin, ciprofloxacin, amikacin, erythromycin, and tetracycline (72%, 29%, 43%, 100%, 100%, respectively). CONCLUSIONS: The real time polymerase chain reaction (RT-PCR) tests and the Vitek 2 compact system showed a high level of accuracy in the detection of Salmonella typhi. Multidrug resistance was observed, which should be a signal to reduce antibiotic consumption.
