Vibrio cholerae is gram-negative bacilli belonging to the Vibrionaceae family generally found in brackish and marine water. Based on the O antigen on the cell wall of the bacteria, they are divided into three major subgroups – V. cholerae O1, V. cholerae O139, and V. cholerae non-O1/non-O139. The serogroups O1 and O139 harboring cholera toxin gene cause diarrhea, while the non-O1/non-O139 can cause a milder diarrhea and extraintestinal infections. We report a case of acute exacerbation of chronic suppurative otitis media by V. cholerae O39, which is classified in the non-O1/non-O139 group. The patient presented with slowly progressive painful ear discharge which evolved over a period of 3 months. V. cholerae O39 was isolated from the ear discharge by culture and confirmed by serologic and molecular testing. The patient improved symptomatically with 1 week of treatment with intravenous ciprofloxacin and tobramycin ear drops.
The incidence of extraintestinal infection caused by Salmonella spp has been increased during the past decade. Here we report a case of a parotid abscess caused by Salmonella enterica subspecies enterica serotype Typhi (S. Typhi) in an individual without any significant abnormality of the parotid gland. A 68-year-old man presented to the surgical department with high-grade intermittent fever associated with painful swelling over the right side of the face, extending into the neck. An ultrasound of the neck revealed an abscess of the right parotid gland. S. Typhi was isolated from the pus drained from the parotid gland. The patient was treated with intravenous followed by oral cephalosporin for a period of 7 days. This case gives an insight into one of the rarer aetiological agents causing parotid abscess.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
