“…It is known that C. perfringens survives the longest in polluted water and is therefore, an excellent indicator of fecal contamination (Bezirtzoglou & Romond, 1990;Pinfold, 1990), even in ecosystems submitted to multiple stress factors (Bezirtzoglou et al, 1996;Bezirtzoglou, Dimitriou, Panagiou, Kagalou, & Demoliates, 1994;Mullie et al, 2002). Another advantage is to specifically detect faecal pollution of a remote origin and this is possible because of the presence of resistant spore forms (Bezirtzoglou, Panagiou, Savvaidis, & Maipa, 1997).…”

In the frame of a project concerning the evaluation of the pollution level and the ozone experimental effect upon some bacterial indicators of a protected ecosystem, water samples were estimated microbiologically before and after saturation with ozone gas for 5, 10, 15, 20 and 30 min. We found that the ozone treatment decreased the concentration in all different bacterial indicators by reducing their number for more than six times after 15 min of application. Total inactivation was observed for C. perfringens vegetative cells. Since there are complex relations between the microbial loading the water characteristics and the action of ozone, further studies are needed to determine the optimum conditions of ozone effect, as its use consists of a promising technology.

“…Like E. coli , C. perfringens does not multiply in most water environments and is a highly specific indicator of fecal pollution. Berzirtzoglou et al [70] reported a comparative study on the occurrence of vegetative cells and spores of Clostridium perfringens in a polluted station of the lake Pamvotis, in rural North-West Greece. The numbers of C. perfringens varied according to the water depth.…”

Water is essential to life, but many people do not have access to clean and safe drinking water and many die of waterborne bacterial infections. In this review a general characterization of the most important bacterial diseases transmitted through water—cholera, typhoid fever and bacillary dysentery—is presented, focusing on the biology and ecology of the causal agents and on the diseases’ characteristics and their life cycles in the environment. The importance of pathogenic Escherichia coli strains and emerging pathogens in drinking water-transmitted diseases is also briefly discussed. Microbiological water analysis is mainly based on the concept of fecal indicator bacteria. The main bacteria present in human and animal feces (focusing on their behavior in their hosts and in the environment) and the most important fecal indicator bacteria are presented and discussed (focusing on the advantages and limitations of their use as markers). Important sources of bacterial fecal pollution of environmental waters are also briefly indicated. In the last topic it is discussed which indicators of fecal pollution should be used in current drinking water microbiological analysis. It was concluded that safe drinking water for all is one of the major challenges of the 21st century and that microbiological control of drinking water should be the norm everywhere. Routine basic microbiological analysis of drinking water should be carried out by assaying the presence of Escherichia coli by culture methods. Whenever financial resources are available, fecal coliform determinations should be complemented with the quantification of enterococci. More studies are needed in order to check if ammonia is reliable for a preliminary screening for emergency fecal pollution outbreaks. Financial resources should be devoted to a better understanding of the ecology and behavior of human and animal fecal bacteria in environmental waters.

“…C. perfringens has been suggested as an alternative bacterial indicator of fecal pollution because it is consistently associated with human wastes (3). C. perfringens, and especially its spores, which are more tolerant to various physicochemical parameters than other fecal indicator bacteria, could serve as a useful indicator in ecosystems suffering from stress factors (4,5).…”

The relationships between indicator bacteria and the organic load were conducted over a year in Lake Pamvotis, in northwest Greece. Total coliforms (TC) and fecal coliforms (FC) were found in water samples from ve different sampling stations. Organic load was estimated using biological oxygen demand (BOD) and chemical oxygen demand (COD) parameters. Increased TC and FC levels were found close to heavily polluted areas. Near-bottom samples had higher levels of bacteria and the numbers of TC and FC were increased during rainfall periods. Low or negative correlations were also observed between the bacteriological indices and BOD and COD levels, thus strengthening the hypothesis that indicator bacteria mainly depend upon the origin of pollution rather than the amount of the organic load. It is conceivable that systematic bacteriological and chemical indices must be monitored in order to evaluate the ecosystem and to protect public health.
