The effect of freezing on photoreactivation of two strains of Escherichia coli (ATCC strain 25922 and O157:H7 strain 961019) and two strains of Enterococcus faecalis (strain ATCC 51299, vancomycin-resistant and strain ATCC 29212, vancomycin-sensitive) following ultraviolet irradiation were examined.

Photoreactivation of microorganisms following UV disinfection can represent a disadvantage to using UV technology for wastewater treatment since recovery may, in some cases, reach several logs. Thus, decreasing photoreactivation can lead to considerable savings in capital and operating costs. Object

Schistosoma mansoni occurs in tropical regions where levels of ultraviolet B (UVB; 290-320 nm) light are elevated. However, the effects of UVB on parasite transmission are unknown. This study examines effects of UVB on the miracidia and sporocysts of S. mansoni, focusing specifically on intramollusc
