ANALYSES OF MICROBIOLOGICAL DATA INDICATES FROM PHYSIC-CHEMCAL PARAMETERS, IN FISH SPECIES FROM SITNICA, LEPENCI AND LUMBARDHI I PRIZRENIT RIVERS (KOSOVA)

The main objective of this study was to isolate enteric pathogenic bacteria from fishes, Shigella spp., Salmonella spp., Coliform and Streptococci, bacteria that might be transmitted to humans after using and consuming fish. Fish samples were collected during March-October 2013-2014 applying electrofishing method alongside Sitnica, Lepenci and Lumbardhi i Prizrenit rivers. Preparation and isolation of Shigella spp., Salmonella spp., Coliform and Streptococci species from fish samples was realized using standard bacteriological procedures. The isolation of enteric bacteria in fish is an indicator of fecal contamination and/or water pollution. From our analyses we found that the level of presence of such bacteria is within the international standard value of 5.0 x 106 CFU/ml that are already approved by many countries. The lack of Salmonella Spp., Shigella spp., Coliform and Streptococci bacteria on the fecal samples of fish can justify the water purity of these rivers according to microbiological aspect, even though there was presence of sewage waste collector, as well as lower water temperatures of these rivers. Also this results could have been impacted from the presence of heavy metals such as Cadmium (Cd) and Plumb (Pb). It is worth mentioning that they values were a bit higher that allowed standards according to the World Health Organization (WHO). As we know, variability of subtypes of different bacterial aspects reflected for research, risk management, and public health strategies.
