Abstract
Non‐typhoidal Salmonella (NTS) are commonly implicated in causing bacteraemia in infants, the elderly and immunosuppressed individuals in sub‐Saharan African countries. However, NTS bacteraemia in otherwise healthy adults from India has been rarely reported. Here, we report a case of bacteraemia caused by Salmonella enterica serovar Choleraesuis (S. Choleraesuis), isolated simultaneously from the blood and urine of an adult febrile patient from Kolkata, India.
A middle‐aged man was admitted to a private hospital in Kolkata with clinical suspicion of acute enteric fever on 25 October 2013. His blood report showed neutropenia and mild thrombocytopenia, with an elevated C‐reactive protein level. The Widal test was negative. S. Choleraesuis isolates were grown simultaneously by microbiological culture of blood and urine samples. The patient recovered without complications following antibiotic therapy. On further characterization, both of the S. Choleraesuis isolates showed identical antibiotic‐susceptibility patterns and virulence‐gene, plasmid and PFGE profiles, confirming their clonality (100% similarity).
This is the first report of S. Choleraesuis bacteraemia associated with a human infection in India. The identification and reporting of uncommon Salmonella serovars from various countries are important for understanding the global epidemiology of salmonellosis.
