Study of enteric fever and antibiogram of Salmonella isolates at a teaching hospital in Kathmandu Valley.

Enteric fever is one of the common public health problems in Nepal. This study was carried out at Nepal Medical College Teaching Hospital located at peri-urban area in Kathmandu Valley to find out the prevalence of enteric fever and the sensitivity pattern of the Salmonella isolates. A total of 479 patients with fever were included in the study. Venous blood samples collected aseptically were subjected to culture and were studied following the standard bacteriological procedure. The overall prevalence of enteric fever was 5.4% (26/479). Of them more than half (65.4%) were caused by S. paratryphi A whereas remaining (34.6%) by S. typhi. The positive rate was higher in children aged 1-15 years (8.9%) followed by 15-30 years of age (4.3%) and others (1.9%). Gender wise, females to male ratio was 1.4:1. The occurrence of infections was higher in Dalit (7.1%), Khas (Brahmin and Chhetri) (5.9%) and Madeshi (5.9%) whereas lowest was in Adibasi Janajati (4.8%). Prevalence rate of enteric fever among different sex, age and ethnic group was not significant (p > 0.05). Isolates were highly sensitive to Amikacin (100.0%) and Ciprofloxacin (96.1%) whereas least sensitive to Gentamycin (68.7%).
