Atividade dos desinfetantes cloreto de benzalcônio e iodóforo sobre cepas de Escherichia coli patogênica aviária isoladas em frangos de corte

Abstract: RESUMO Os objetivos deste estudo foram avaliar a eficácia dos desinfetantes cloreto de benzalcônio (QAC) e iodóforo (I) sobre 10 cepas APEC (Escherichia coli patogênica aviária), bem como verificar se a característica alta patogenicidade está associada a uma maior resistência a estes compostos. O método utilizado foi o de diluição através do teste qualitativo de suspensão. As variáveis estudadas foram: concentrações do QAC (300, 150, 75 e 50 ppm) e do I (100, 75, 50 e 25 ppm), tempos de contato (5, 10 e 20 min… Show more

“…The biocidal effect of QA has been attributed to the direct action of the drug on the plasma membrane, leading to protein denaturation, membrane rupture, and consequent death of the pathogen [33,34]. QAC has long been used a sanitizer for human and animal safety (i.e., hospital, agricultural, and industrial environments) [36], due to its good stability, low toxicity, lack of odor, low corrosiveness, and biodegradability [35].…”

“…Quaternary ammonium compounds (QAC) are cationic surfactants commonly used as antiseptics and disinfectants in human and veterinary medicine due to their microbicidal action [33], which denatures proteins of microbial cell membranes and cytoplasm [34]. In addition, they possess other properties, such as low toxicity, good stability, biodegradability, lack of odor, little corrosiveness, and low skin irritation potential toward the skin and mucous membranes [35]. These characteristics have enabled their use in domestic, agricultural, and hospital disinfection applications, as well as in food industries, animal facilities, and swimming pools [36].…”

“…Para os animais cujo problema é indicado eutanásia, o método aceito é de deslocamento cervical (Pessoa et al, 2013). Há também a necessidade de os produtores terem planos para situações emergenciais, como surtos de doenças, falha de equipamentos, desordens naturais entre outros, sendo importante a observação do local em que o aviário será construído, a fim de o local minimizar riscos à biossegurança, exposição a situações de risco ambiental e/ou climático (Carvalho et al, 2017).…”
