Abstract

Pharmaceutical manufacturing workers are exposed to significant amounts of product ingredients, including antibiotics. Such exposure could affect their nasal microflora. To assess the effect of exposure to various unidentified pharmaceutical ingredients in cephalosporin-manufacturing and non-cephalosporin plants on the nasal carriage of Staphylococcus spp. and their antibiotic resistance. Nasal swab samples were collected from 39 workers in both plants on three different occasions. Staphylococci were isolated and identified to genus level. Antibiotic resistance profiles were determined and subsequent identification to species level was performed. There was complete absence of S. aureus in the samples collected from workers in both facilities. Multiple drug resistant coagulase-negative staphylococci (MDR CONS) prevalence rates were higher in the non-cephalosporin plant than in the cephalosporin plant, with resistance towards six classes of antibiotics. S. epidermidis was the prevalent species in the non-cephalosporin plant and S. haemolyticus prevailed in the cephalosporin-producing plant. The observed prevalence of CONS in both production plants was the same. However, exposure to intermittent non-cephalosporin pharmaceuticals results in higher prevalence of MDR CONS compared to continuous exposure to cephalosporin.
