Article Abstract:
A study was conducted to quantitatively determine and compare the concentrations of viable Cryptosporidium parvum and Cryptosporidium hominis oocysts, Giardia lamblia cysts, and spores of human-virulent microsporidiai in sewage sludge during the activation secondary treatment process and in the corresponding sewage sludge end products. The analysis has shown that the pathogen load must be reduced to a level that does not pose any public health risk so that the sewage sludge end products can be used without restriction on agricultural lands growing ready-to-eat crops, .

Article Abstract:
The study investigated whether Cryptosporidium parvum oocysts or Giardia cysts are present in the fecal droppings of migratory Canadian geese Branta canadensis. Analysis of the fecal droppings indicate the presence of the oocytes. This finding has environmental health implications because C. parvum and other Giardia species cause a number of life-threatening infections in humans. These birds could pose hazards for human health by acting as mechanical carriers of the infectious oocytes.

Article Abstract:
The weekly samples of recreational bathing waters were examined during summer months for human-virulent microsporidian spores and water quality parameters in association with high and low bather numbers during weekends and week days respectively. Findings reveal that bathing in public waters results in exposure to potentially viable microsporidian spores.
