“…Já o gênero Aeromonas, considerado ubíquo no meio ambiente, é composto por bacilos Gram-negativos amplamente distribuídos no ambiente aquático, podendo ser encontrados tanto em água doce como em salobras, e até mesmo em águas residuais, e são considerados um importante patógeno associado à contaminação alimentar (Cabral, 2010), e responsável por vários surtos alimentares (Beaz-Hidalgo e Figueras, 2013). Indivíduos desse gênero podem causar principalmente gastroenterite em crianças, idosos e pacientes imunocomprometidos, mas também septicemia e óbito (Gowda et al, 2015).…”

RESUMOA contaminação da água do semiárido brasileiro se tornou uma preocupação constante para os pesquisadores no país, principalmente porque essa região é considerada uma das mais carentes no Brasil e a água nessas localidades representa um importante veículo para a transmissão de doenças associadas aos recursos hídricos. Nessa pesquisa foram coletados dados físicos e químicos, bem como uma amostra da água de quatro reservatórios do semiárido potiguar durante o período seco e chuvoso de 2013 e 2014. Na Universidade Federal do Rio Grande do Norte (UFRN) essas amostras foram processadas e avaliadas, em laboratório, quanto às características físico-químicas e microbiológicas. Os procedimentos de isolamento e identificação microbiana seguiram as normas do Standard Methods for Examinations of Water and Wastewater. Em seguida foi usado o sistema Vitek II (Bio-Merieux®) para a identificação dos espécimes e calculada a frequência de ocorrência dos isolados. Ao todo foram isoladas e identificadas 168 bactérias, sendo 97% delas Gram-negativas e apenas 3% Gram-positivas. Dentre os isolados, 73,2% foram identificados como da família Enterobacteriaceae e de um modo geral, os gêneros mais constantes na água dos reservatórios foram Vibrio e Aeromonas. Entre as enterobactérias, as espécies Escherichia coli, Enterobacter complexo cloacae e Klebsiella pneumoniae foram as mais frequentes. Não houve diferença estatistica entre o número ou grupo morfotintorial encontrados nos períodos, p=0,255 e p=0,237 respectivamente. Os dados analisados indicaram uma possível contaminação da água dos reservatórios estudados por uma fonte de material fecal humano e/ou animal.Palavras-chave: contaminação hídrica, enterobactérias, região semiárida.

“…The newly identified etiological agents of diarrheal disease are mesophilic aeromonadswhich have emerged as an important public health hazard [ 2 ]. There is mounting evidence of their involvement in gastrointestinal and extraintestinal infection in human beings [ 3 , 4 ]. The genus Aeromonas comprises of two different groups of bacteria.…”

“…Mesophilic motile aeromonads are ubiquitous and autochthonous aquatic microorganisms occurring in fresh water, sewage and brackish water [ 6 ] and in chlorinated and unchlorinated drinking water [ 7 , 8 ]. Besides these aeromonads occur as the normal microbial flora of many aquatic and terrestrial animals and are proven diseases in various cold blooded and warm blooded animals including fishes, amphibians, reptiles, birds and other domestic animals [ 9 , 10 ]. Not only the aquatic environment plays an important role in the dissemination of aeromonads, different foods, especially, fishes and other seafood, raw and cooked meat,chicken, vegetables, milk and milk products can be a potential vehicle for human infections as well as animals [ 11 - 16 ].…”

Aeromonas is recognized to cause a variety of diseases in man. In humans, they are associated with intestinal and extra-intestinal infections. With the growing importance of Aeromonas as an emerging pathogen, it is important to combat this organism. It is indisputable that Aeromonas strains may produce many different putative virulence factors such as enterotoxins, hemolysins or cytotoxins, and antibiotic resistance against different antibiotics. The ability of these bacteria to grow competitively at 5°C may be indicative of their potential as a public health hazard. Comprehensive enteric disease surveillance strategies, prevention and education are essential for meeting the challenges in the years ahead. It is important for us to promote the value of enteric cultures when patients have a gastrointestinal illness or bloody diarrhea or when multiple cases of enteric disease occur after a common exposure. With the growing importance of Aeromonas as an emerging pathogen, it is important to combat this organism. It is indisputable that Aeromonas strains may produce many different putative virulence factors, such as enterotoxins, hemolysins or cytotoxins. It has been established that aerolysin is a virulence factor contributing to the pathogenesis of Aeromonas hydrophila infection. Fish and chicken play an important role in the transmission of this pathogen to humans. In the present study, the high prevalence of toxin-producing strains was found among the Aeromonas isolates. The ability of these bacteria to grow competitively at 5°C may be indicative of their potential as a public health hazard. The present review was constructed with a view to highlight the zoonotic importance of Aeromonas pathogen in fish and chicken meat.

“…Aeromonas species are widely distributed in soil, foodstuffs, and the aquatic environment, where they are opportunistic pathogens of poikilotherms, causing numerous diseases such as "red leg" disease in frogs, ascites in carp (12), and other diseases in freshwater fish (13). Additionally, Aeromonas species are known to cause gastrointestinal and extraintestinal infections in humans (14,15). Based on human fecal carriage rates, Aeromonas species are present in the gastrointestinal tracts of up to 4% of the healthy population (16).…”

The mobile colistin resistance gene is globally disseminated in both and species, with the latter potentially serving as a reservoir for this gene. Here, we investigated the prevalence of in rectal swabs from humans, in food-producing animals and their products, and in the aquatic environment, and we investigated the genetic relationships between the -positive isolates. An enriched broth screening method was used to detect in samples, and species identification of isolates from positive samples was carried out by matrix-assisted laser desorption ionization-time of flight mass spectrometry and shotgun sequencing. All -positive isolates were subjected to antimicrobial susceptibility testing, conjugation, and whole-genome sequencing. Ten isolates, including 2 from human rectal swabs, 1 from pork, 3 from chicken meat, and 4 from the aquatic environment, were positive for , but only 2 showed resistance to colistin. In addition to the variants identified previously (the novel variants were termed to), all isolates harbored -like genes downstream of the variants. The MCR-3.13 to MCR-3.18 proteins exhibited only 89.2% to 96.1% amino acid identity to the original MCR-3 protein. Whole-genome sequence analysis indicated diversity within the genetic environments of -positive isolates and possible transmission between different sources in China and even worldwide. Close relationships between -positive and-negative isolates suggested that might be common in species, which are not inherent hosts of but may act as an important reservoir of this mobile colistin resistance gene.
