“…Of particular concern is A. veronii as the most frequent aeromonad isolated in summer, having a wide environmental host range, and being pathogenic to humans (Martin-Carnahan and Joseph, 2005). Patients with underlying medical conditions and immunocompromised hosts are more likely to succumb to Aeromonas infections, therefore a thorough history of occupational and recreational exposure is crucial for clinicians in order to provide the appropriate management (Igbinosa et al, 2012).…”

a b s t r a c tA two-season investigation of the wastewater treatment plant (WWTP) effluent, of related waters, sludge and fish across a wide area and 11 stations, with emphasis on Aeromonas spp. was conducted. Aeromonas veronii was the prevailing aeromonad isolated by MALDI TOF MS in the summer period. A rise of Aeromonas hydrophila was observed in summer in raw sewage, treated wastewater and effluent-carrying canal. The ratio of aeromonad species retrieved from fish tissues did not correspond with the water and sludge findings, as in spring in the effluent-carrying canal fish carried Aeromonas salmonicida ssp. salmonicida and Aeromonas bestiarum, while in summer mainly A. veronii and Acinetobacter johnsonii were isolated from fish tissues in the same location. No correlation was established between fecal coliforms/ enterococci and aeromonad occurrence. All retrieved Aeromonas species demonstrated a distinct spectral pattern, with peaks showing unique mass distribution ranging from 4000 to 10,000 Da. Hierarchical clustering separated aeromonads of all isolated species and clustered closely related strains together. Resistance was determined towards amoxicillin, and frequently towards sulfamethoxazole and erythromycin. In summer, a high proportion of water and sludge Aeromonas species demonstrated multiple resistance patterns towards five or more antimicrobials. The quinolone resistance of water aeromonads was mostly related to A. veronii. There are potential health concerns regarding aeromonad exposure amongst recreational fishermen who come into contact with fish inhabiting waters downstream from the WWTP, and WWTP workers who are occupationally exposed to wastewaters and their aerosols.

“…Resistance is particularly relevant in the pathogenic species of Aeromonas spp. in which multidrug resistance have been identified (ALCAIDE et al, 2010;MARTINELI et al, 2010;JANDA & ABBOTT, 2010;IGBINOSA et al, 2012). However, little is known about foodborne and environmental strains, especially in Brazil.…”

SUMMARYBacteria of the genus Aeromonas can be isolated from clinical, food and environmental samples. For dairy products contamination can be caused by the presence of the agent in the feedstock used for production or due to unsatisfactory hygienic conditions during processing. The present study aimed to assess Aeromonas isolates behavior in the presence of common antimicrobials, considering the importance of Aeromonas spp. as an emerging pathogen of foodborne diseases, the indiscriminate use of antimicrobials to treat human pathologies, in addition to the role that milk and its derivatives play in human feeding habits. The processing steps during dairy products manufacturing were studied looking for vulnerable points or products where Aeromonas could be present and, subsequently, either pass it to the final products or disseminate the micro-organism in different processing stages of Minas and Colonial cheeses. The results show high levels of resistance: 33.6% of 98 isolates of Aeromonas spp. were resistant to all 15 antibiotics tested, corresponding to 7.5% of the isolates from Colonial cheese and 51.7% from Minas cheese, thus showing greater resistance among the samples collected in the industry. Multiple antimicrobial resistance was verified in 100% of the isolates, which reveals a profile which is alarming for public health. KEY-WORDS:Antimicrobial. Colonial Cheese. Minas Frescal Cheese. RESUMOBactérias do gênero Aeromonas podem ser isoladas de amostras clínicas, alimentares e ambientais. Para os derivados lácteos a contaminação decorre da presença do agente na matéria prima utilizada para produção, ou devido a condições higiênicas insatisfatórias durante o processamento. Considerando a importância da Aeromonas spp. como patógeno emergente de doenças de origem alimentar, o uso indiscriminado de antimicrobianos nas patologias humanas, além do papel fundamental que o leite e seus derivados representam na alimentação humana, o presente estudo teve por objetivo verificar o comportamento dos isolados frente à ação de antimicrobianos de uso comum. Foram pesquisados produtos e pontos do fluxograma do processamento de derivados lácteos, que poderiam veicular o gênero Aeromonas e permitir sua ocorrência nos produtos finais, ou atuar como disseminadores do micro-organismo nas diferentes etapas do processamento do queijo Minas Frescal e do queijo Colonial. Os resultados demonstram altos níveis de resistência: 33,6% dos 98 isolados de Aeromonas spp. foram resistentes a todos os 15 antimicrobianos testados, correspondendo a 7,5% dos isolados do queijo Colonial e 51,7% do queijo Minas Frescal, ocorrendo, portanto, maior resistência entre as amostras coletadas na indústria. 100% dos isolados apresentaram resistência múltipla, resultado que revela um perfil preocupante para saúde pública. PALAVRAS-CHAVE:Antimicrobiano. Queijo Colonial. Queijo Minas Frescal.
