New Delhi metallo-beta-lactamase-1 (NDM-1) will soon become the most commonly isolated and distributed metallo-beta-lactamase worldwide due to its rapid international dissemination and its ability to be expressed by numerous Gram-negative pathogens. NDM-positive bacteria pose a significant public health threat in the Indian subcontinent and the Balkans, which have been designated as endemic regions. Our study was focused on urban rivers, a lake and springheads as a potential source of NDM-1-producing strains in Serbia, but also as a source of other metallo-beta-lactamases and extended-spectrum beta-lactamase (ESBL) producing bacteria. A total of 69 beta-lactam resistant isolates, belonging to 12 bacterial genera, were collected from 8 out of 10 different locations in Belgrade, of which the most were from a popular recreational site, Ada Ciganlija Lake. Phenotypic tests revealed 7 (10.14%) ESBL-producing isolates and 39 (56.52%) isolates resistant to imipenem, of which 32 were positive ...for metallo-beta-lactamase (MBL) production. PCR and sequencing revealed the presence of genetic determinants for SHV (3 isolates), DHA-1 (1 isolate) and CMY-2 (1 isolate) beta-lactamases. However, we did not detect any NDM-1-producing strains (previously described cases of NDM-1 from Serbia were limited to Belgrade), so we propose that Serbian NDM-1 is in fact a transplant and a nosocomial, rather than an environmental, issue and that Serbia is not an endemic region for NDM-1.
