BACKGROUND The aim of this study was to detect and characterize Cryptosporidium spp. in water samples collected from recreational ponds of Chaharmahal va Bakhtiyari Province of Iran. METHODS Thirty water samples were collected from November 2009 to May 2010. Each sample contained 10 liters of water. We used the SSU rRNA-based PCR-RFLP technique. RESULTS Out of thirty samples examined, 6 (20...

This review addresses both historical and recent investigations into viral contamination of marine waters. With the relatively recent emergence of molecular biology-based assays, a number of investigations have shown that pathogenic viruses are prevalent in marine waters being impacted by sewage. Research has shown that this group of fecal-oral viral pathogens (enteroviruses, hepatitis A viruse...

Recreational waters should be considered as risks for Enterococcal infections in regions with high utilization and long exposure periods. The aim of this study was to investigate the resistance of Enterococci to selected antibiotics and some heavy metals [Pb, Fe, Zn and Cr]. A total of 75 Enterococcal isolates was obtained from 54 bathing and fishing water samples from 9 bathing and fishing are...

Microbial source tracking (MST) has become a focus of some recreational beach monitoring programs. Suspected sources of contamination include human sewage, agricultural runoff, and feces from wildlife and domestic animals, depending on beach location. Waterfowl have been suggested as a primary source of fecal contamination at many beaches, but techniques to “prove” contaminating microbes are of...

background and objectives: the usepa has suggested faecal enterococci as the primary bacterial indicators. of more importance is their direct correlation with swimmer-associated gastroenteritis in recreation water quality monitoring. in contrast to other seawater bodies with 3.5% salinity, the recreational waters in the southern coast of the caspian sea possess its own salinity (about 1% w/v) a...

Cyanobacteria are prokaryotic, plantlike organisms present in lakes, recreational waters, and reservoirs, and often dominate phytoplankton communities in warm, nutrient-enriched hard waters. A stable water column rich in certain nutrients, especially nitrogen and phosphorus, is associated with favorable environmental conditions that support development of cyanobacterial population maxima or "bl...

This paper presents some issues related to designing forest landscape located close to the areas of watercourses and water reservoirs. Surface waters, beside forests and diverse terrain relief, constitute the main element deciding about tourist and recreation attractiveness of every such area. Some surveys on the evaluation of forest recreational potential prove that the forest attractiveness i...

Cyanobacteria and cyanotoxins have been more and more studied during the last decades with regard to environment and health issues. More recently the consequences of climate change reinforced the need for research in view of a better management of cyanobacteria blooms. In this context the exploitation of the water quality survey of 26 recreational lakes in Brittany (north western France) betwee...
