A rare urinary tract infection by Salmonella paratyphi A

Urinary Tract Infection (UTI) caused by Salmonella is very rare and occurs mainly in immunocompromised patients, infants and those over 60 years of age. A 12-year-old patient admitted with history of fever, burning micturition and suprapubic abdominal pain, diagnosed with a rare variant of Salmonella from UTI which had showcased abnormal biochemical reaction unlike typical Salmonella paratyphi A reactions. Here, we are communicating the rare H₂S variant Salmonella paratyphi A, causing UTI which caused clinical and microbiological confusion in the diagnosis. A high suspicion is required for adequate diagnosis and treatment when non-lactose fermenting colonies are seen in the culture plate.
