Paratyphi Pneumonia- Does What You Eat Matter?

Abstract

Most common signs and symptoms of typhoid are localised to gastrointestinal system. Less commonly, extraintestinal infectious complications occur with enteric fever. The present case report is about a 29-year-old female, without risk factors, who presented with fever, loose stools and cough of five days duration. The patient was diagnosed to have paratyphi A bacteraemia, with clinical and radiological features of pneumonia. Her sputum cultures were sterile, and hence paratyphi A pneumonia was diagnosed. She received 14 days of antimicrobial therapy and recovered. Vi-based monovalent vaccines do not offer protection against most paratyphoid fever, because only Salmonella serovars Typhi, and paratyphi C carry the Vi antigen. Further studies are needed on bivalent and polyvalent typhoid vaccines covering all serovars.
