Foodborne diseases represent a major risk to public health worldwide. Pathogenic bacteria can live in the form of biofilm within the food industry, providing a permanent source of contamination. The aim of this study was to evaluate the influence of the types of adhesion surfaces on Salmonella biofilm formation at eight different times, and analyze the action time of a bacteriophage pool on established biofilms. Most of the samples used were classified as weak biofilm producers, with serovars Enteritidis and Heidelberg showing the highest frequency of biofilm formation. Glass and stainless steel surfaces significantly favored biofilm formation at 60 and 36 h of incubation respectively, but the polyvinyl chloride surface did not favor biofilm production, suggesting that the type of material may interfere with production. The bacteriophage pool action period focused on 3 h, but treatment of 9 h on glass surface biofilms was superior to other treatments because it affected the largest number of samples. These results suggests that some surface types and Salmonella serotypes may promote biofilm formation and indicate bacteriophages as an alternative to control biofilms. But further studies are required to prove the effectiveness and safety of bacteriophage therapy as an alternative in the antimicrobial control in the processing plants.

Entender a percepção da população sobre o risco de enfermidades zoonóticas, configura-se, como uma ferramenta de grande valia para o planejamento e a organização de ações que busquem melhorias na qualidade de vida humana e animal, tais ações dependem, sobretudo do conhecimento da população. Nesse sentido, o presente estudo objetivou enfocar conceitos teóricos básicos sobre zoonoses, entrevistando proprietários ou não de cães e gatos com diferentes faixas etárias e diferentes condições socioeconômicas e culturais. De fevereiro a abril de 2012 foram entrevistadas 2.036 pessoas residentes em área urbana em diversos municípios do eixo Campinas - Ribeirão Preto e feitas as análises descritivas das respostas. Diante dos resultados obtidos, verificou-se que, a maior parte da população conhece ou já ouviu falar sobre as principais enfermidades abordadas. No entanto, o modo de prevenção e as medidas profiláticas ainda não encontram totalmente elucidados para a população, necessitando de ênfase para a adoção de medidas educativas em massa, com abordagem dos principais pontos críticos sobre zoonoses.

Ligações entre o uso indiscriminado de antimicrobianos na produção de animais, que se destinam à alimentação humana, conferindo pressão seletiva sobre microrganismos, e uma emergência na sua existência, surgimento, disseminação e transferência de genes que conferem de resistência a drogas antimicrobianas constituí preocupação global crescente. Processos de resistência antimicrobiana ocorrem de modo natural ou adquirido, sendo a maneira adquirida a mais preocupante. Vários são os mecanismos de transferência de resistência antimicrobiana, sobretudo elementos genéticos móveis são determinantes ao desenvolvimento de cepas bacterianas resistentes. Enterobactérias são frequentemente isoladas em produtos avícolas, sendo relatada múltipla resistência antimicrobiana e surtos de doenças em humanos. O objetivo da presente revisão foi discutir e expor aspectos relacionados à transferência de resistência antimicrobiana, destacando os impactos da utilização de antimicrobianos e o processo de transferência de resistência antimicrobiana entre bactérias patogênicas, zoonóticas e comensais de aves.

The aim of this study was to provide the first report on a new host for the digenean Paratanaisia bragai in the caninde macaw Ara ararauna along with the pathological aspects of the infection in the new host. The microscopic findings revealed the presence of granulomatous interstitial nephritis. This study contributes towards knowledge of parasitism by P. bragai in A. ararauna, and emphasizes the need to use best practices in wildlife conservation parks.Keywords: Parasite, birds, histopathology, wildlife, macaw. ResumoO objetivo deste estudo foi relatar, pela primeira vez, a arara canindé Ara ararauna como um novo hospedeiro para o digenético Paratanaisia bragai, bem como relatar aspectos patológicos relacionados à infecção no novo hospedeiro. Os achados microscópicos revelaram nefrite intersticial granulomatosa. Este estudo contribui para o conhecimento do parasitismo por P. bragai em A. ararauna e ainda faz um alerta para a adoção de boas práticas de criação em criatórios conservacionistas da fauna silvestre.

Fungal infections caused by Macrorhabdus ornithogaster, Aspergillus flavus, Candida albicans has been described as responsible for promoting gastrointestinal, respiratory, neurological and dermatological disorders in several avian species. The present paper describes the clinical signs, histopathological exams, treatment and preventions and of a chronic case of three fungal infections concomitant in australian parakeet (Melopsittacus undulatus). The animals came from a commercial breeding facility and sent to

Three adult birds of the species Ara chloropterus and five of the species Ara ararauna from a conservation breeding facility suffered a massive attack by honeybees. The A. chloropterus birds presented swollen puncture lesions with stingers (mainly in the facial regions without feathers), swelling of the eyelids and subcutaneous tissue, and respiratory distress, and they were treated with intramuscular injections of 1.67 mg/kg of promethazine and 10 mg/kg of hydrocortisone followed by removal of the stingers. Complete remission of the clinical signs occurred 48 hours after start of treatment. The five A. ararauna birds died before they arrived at the veterinary hospital, and the necropsies found stingers in the areas of the face without feathers and the subcutaneous tissue, which were associated with erythema, bruising, and swelling. Food content from the crop was found in the oral cavity and the tracheal lumen, and marked congestion was observed in the heart, liver, spleen, lungs, kidneys, brain, and cerebellum. Among the histopathological findings, significant swelling of the myocytes in the endocardium and vascular dilation with erythroid repletion were observed, and there were multifocal areas of centrilobular necrosis associated with severe congestion and hemorrhaging in the hepatic tissue. Severe acute tubular necrosis and hydropic-vacuolar degeneration were observed in the kidneys. The clinical signs and pathological findings suggest envenomation due to a massive bee attack, the first such report for Psittacidae.

The aim of this study was to report the burrowing owl Athene cunicularia as a new host for the filarid nematode Pelecitus sp. in southeastern Brazil for the first time, as well as reporting the occurrence of this nematode species in the body cavity, near the cervical air sac and lung region. This study contributes towards knowledge of parasitism in Brazilian wild birds and an anatomical region of the host as an infection site for Pelecitus sp.
