“…Sewage effluents, agricultural run-off and direct deposit of faecal materials from wild animals and birds are the major sources of the bacteria in aquatic environments (Alcaide et al, 1984;Baudart et al, 2000;Johnson et al, 2003;Abulreesh et al, 2005). Salmonella species have been found in almost all types of aquatic environments that receive faecal contamination, that include drinking water (Bhatta et al, 2007), rivers (Pianetti et al, 1998;Polo et al, 1998;Polo et al, 1999;Dionisio et al, 2000;Lemarchand & Lebaron, 2003;Arvanitidou et al, 2005;Haley et al, 2009), lakes (Claudon et al, 1971;Arvanitidou et al, 1995;Sharma & Rajput, 1996), ponds (Shellenbarger et al, 2008), marine waters (Matinez-Urtaza et al, 2004a;Martinez-Urtaza et al, 2004b;Martinez-Urtaza & Liebana, 2005;Harakeh et al, 2006), run-off water (Claudon et al, 1971), treated and untreated wastewater (Ho & Tam, 2000;Melloul et al, 2002;Espigares et al, 2006, Mafu et al, 2009 worldwide. Abulreesh et al (2004) were unable to detect salmonellae in water samples from a village pond that receives direct faecal contamination from waterfowl, nevertheless, they managed to isolate the bacterium from bottom sediments of the same pond.…”

“…Furthermore, Salmonella spp. were successfully detected in Spanish fresh and marine water that received faecal pollution in the absence of faecal indicators, as well as in aquatic environments with low degree of pollution (Pianetti et al, 1998;Baudart et al, 2000;Dionisio et al, 2000). Thus, the ability of faecal indicators to predict the presence of salmonellae in polluted environmental waters remains questionable, and the absence of faecal indicators is not always a reliable indication of the absence of Salmonella spp.…”

“…As a result, indicator bacteria such as Salmonella, "total fecal coliforms", and "total fecal streptococci" are commonly used to determine the risk of fecal contamination and the possible presence of pathogens in water and wastewaters [100]. Other emerging pathogenic microorganisms, Campylobacter, Aeromonas, and Yersinia genera [101] and in recent years, also bacteriophages, have been proposed by several groups as indicators for the microbial quality of water since they are more suitable to signal viral contamination of water sources [102]. On the other hand, monitoring of microorganisms is not only of environmental concern; from a military point of view, there are a number of pathogenic bacteria that can be considered possible biological warfare agents [103].…”

Biosensors can be excellent analytical tools for monitoring programs working to implement legislation. In this article, biosensors for environmental analysis and monitoring are extensively reviewed. Examples of biosensors for the most important families of environmental pollutants, including some commercial devices, are presented. Finally, future trends in biosensor development are discussed. In this context, bioelectronics, nanotechnology, miniaturization, and especially biotechnology seem to be growing areas that will have a marked influence on the development of new biosensing strategies in the next future.

The presence of Aeromonas spp. in water can represent a risk for human health. Therefore, it is important to know the physiological status of these bacteria and their survival in the environment. We studied the behavior of a strain of Aeromonas hydrophila in river water, spring water, brackish water, mineral water, and chlorinated drinking water, which had different physical and chemical characteristics. The bacterial content was evaluated by spectrophotometric and plate count techniques. Flow cytometric determination of viability was carried out using a dual-staining technique that enabled us to distinguish viable bacteria from damaged and membrane-compromised bacteria. The traditional methods showed that the bacterial content was variable and dependent on the type of water. The results obtained from the plate count analysis correlated with the absorbance data. In contrast, the flow cytometric analysis results did not correlate with the results obtained by traditional methods; in fact, this technique showed that there were viable cells even when the optical density was low or no longer detectable and there was no plate count value. According to our results, flow cytometry is a suitable method for assessing the viability of bacteria in water samples. Furthermore, it permits fast detection of bacteria that are in a viable but nonculturable state, which are not detectable by conventional methods.During the last decade scientific interest has turned to members of the genus Aeromonas as human and animal pathogens. Many Aeromonas species have been associated with human diseases, including gastroenteritis, hemolytic-uremic syndrome, septicemia, etc. (21, 30, 48).Aeromonas spp. are common aquatic microorganisms that occur in seawater, irrigation water, river water, brackish water, freshwater, groundwater, spring water, sewage-contaminated water, and activated sludge (4,7,9,14,15,23,24,37,43).The wide distribution of aeromonads in different aquatic ecosystems underlines their capacity to adapt to environments with different trophic levels. Several studies have shown that the phenospecies Aeromonas hydrophila is prevalent in cleaner water, whereas Aeromonas caviae is prevalent in water with a high level of fecal pollution; the frequencies of the other phenospecies appear to be unrelated to environmental conditions (3,15,17,23).These bacteria have also been isolated from chlorinated and unchlorinated drinking water and from bottled mineral water, which shows that they are able to withstand long periods of nutrient limitation (6,16,19,20,29,31,46,50). The survival of aeromonads in these ecosystems can be correlated with their capacity to produce and live within biofilms on the surfaces of pipes and bottles (26); on the other hand, it is known that Aeromonas spp. can cope with nutrient limitation conditions by entering into a starvation survival state (33).The growing interest in these organisms addresses aquatic environments, because these environments represent an important reservoir of aeromonads. It is assumed that huma...
