“…hydrophila strains associated with human gastroenteritis are capable to grow in foods at refrigeration temperatures, currently considered adequate for preventing the growth of foodborne pathogens (Palumbo et al, 1985). Other authors reported wound infections in humans caused by A. hydrophila (Campbell, 2001;Hiransuthikul et al, 2005).…”

Abstract:Different solutions of royal jelly, royal jelly and rape honey mix, and rape honey (2, 5, 10, 20, and 30%) were contaminated with bacterial suspension of Aeromonas hydrophila (ATCC 7965). Colony counts for each test substances were determined after incubation for 24 h and 48 h and those concentrations which completely inhibited the growth of the test strain were assigned as Real Bactericidal Concentration (RBC) or 100% inhibition. Royal jelly and rape honey mixes possessed a lower antibacterial activity than rape honey. The concentrations of royal jelly (10, 20, and 30%) had a total inhibitory effect against A. hydrophila (ATCC 7965). Royal jelly, royal jelly and rape honey mix, and rape honey have a potential as alternative therapeutic agents against A. hydrophila.

“…was isolated by selective enrichment performed initially in tryptic soy broth (TSB) supplemented with ampicillin at a concentration of 30 milligrams per liter (ABEYTA JUNIOR et al, 1990). After incubation, the selective enrichment cultures were plated on phenol-amideampicillin red agar (PALUMBO et al, 1985) and ampicillin-dextrin agar (HAVELAAR & VONK, 1988), which were incubated again at 28°C for 24 hours and examined for the presence of large yellow colonies (3-5 mm) surrounded by a halo resulting from the hydrolysis of starch or dextrin, characteristics of Aeromonas. Up to five colonies were inoculated into tilted tubes of trypticase-soy agar (TSA) and, after confirming the presence of pure cultures; they were plated on triplesugar-iron (TSI) agar and subjected to the tests of motility, oxidase, catalase and resistance to the vibriostatic agent O/129 (POPOFF, 1984).…”

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.
