“…These results resemble those previously reported by other authors (Burke et al, 1982;Farmer et al, 1992;Krovacek et al, 1992;Seidler et al, 1980), who found a higher frequency of isolation during the summer months.…”

“…Isolation of Aeromonas spp. was successful, even in heavily contaminated samples, like those from the WWTPs; however, isolation was easier to accomplish when samples had a lower content of mesophilic-aerobic, coliform, and fecal-coliform organisms (Tables 7 and 8), as was the case for the DWPs, which is in accord with the report by Seidler et al (1980). Most of the outflowing water samples (Table 8), from both DWPs containing Aeromonas spp., had numbers of aerobic-mesophilic, coliform, and fecal-coliform organisms within the official Mexican norm (NOM-093-SSA1-1993;Norma Oficial Mexicana, 1993a).…”

“…Aeromonas has been isolated from a variety of water sources: rivers, streams, dams, wells, lakes, drinking-water-treatment plants (Seidler et al, 1980), and even from the municipal distributing pipelines (Kirov, 1993;Krovacek et al, 1992).…”

The frequency of Aeromonas spp in three wastewater‐treatment plants (WWTPs) and two drinking‐water plants (DWPs) in México City was determined. Samples were taken throughout a year by the Moore's swab technique. A total of 144 samples were obtained from WWTPs and 96 from DWPs of both incoming and outflowing water. Aeromonas spp was isolated in 31% of the samples, from both kinds of sources. The technique used for the isolation of the pathogen was suitable for samples with high associate microbiota content and for those with a scarce microbial content. The presence of mesophilic‐aerobic, coliform, and fecal‐coliform organisms was investigated to determine whether there was any correlation with the presence of Aeromonas spp. Most samples from WWTP, which did not comply with the Mexican standards, had the pathogen, and some of the samples from the outflow of the DWP, which were within the limits set by the Mexican standards, also had Aeromonas spp.    Most samples containing Aeromonas spp. had concentrations below 0.1 ppm residual chlorine, and the strains were resistant to 0.3 ppm, which supports the recommendation to increase the residual chlorine concentration to 0.5 to 1.0 ppm, as recommended by the Mexican standards.

Ae.ro.mo' nas . Gr. n. aer air, gas; Gr. n. monas unit, monad; M.L. fem. n. Aeromonas gas(‐producing) monad. Proteobacteria / Gammaproteobacteria / Aeromonadales / Aeromonadaceae / Aeromonas Cells straight, coccobacillary to bacillary with rounded ends, 0.3–1.0 × 1.0–3.5 µm. Occur singly, in pairs, or rarely in short chains. Gram negative. Most species are motile by a single, polar flagellum of 1.7 µm wavelength; peritrichous flagella may be formed on solid media in young cultures and lateral flagella occur in some species. Facultatively anaerobic. Chemoorganotrophic, displaying oxidative and fermentative metabolism of D ‐glucose. Acid and often acid with gas produced from many carbohydrates, especially D ‐glucose. Nitrate is reduced to nitrite. A variety of exoenzymes such as arylamidases, amylase, DNase, esterases, peptidases, and other hydrolytic enzymes are produced. Main cellular fatty acids are hexadecanoic acid (C 16:0 ), hexadecenoic acid (C 16:1 ), and octadecenoic acid (C 18:1 ). Usually oxidase positive and catalase positive . Optimum growth temperature varies between 22°C and 37°C; growth temperature can range from 0 to 45°C, and some species do not grow at 35°C. Generally resistant to 150 μg of the vibriostatic agent 2,4 diamino‐6, 7‐diisopropylpteridine (0/129) . Occur in fresh, brackish, tap, well, and chlorinated water, as well as biosolids and sewage. Some of the species have been associated with disease in a wide variety of warm‐blooded and cold‐blooded animals, including humans, domestic animals, frogs, fresh and salt water fish, and invertebrates. The phylogenetic position of Aeromonas , as determined by 16S rRNA gene sequence analysis, is in the Gammaproteobacteria , with its closest relatives in the families Vibrionaceae and Enterobacteriaceae . 16S rDNA sequences (signature sequences) have been determined for nearly all validly named species and are deposited in GenBank, EMBL, or RDP databases (Table BXII.γ180). The mol % G + C of the DNA is : 57–63. Type species : Aeromonas hydrophila (Chester 1901) Stanier 1943, 213 ( Bacillus hydrophilus Chester 1901 , 235.)
