Isolation of Aeromonas hydrophila in piglets

The production of Alentejano breed pig started a recovery two decades ago due to increasing demand for gourmet products. These pigs are raised in rotational semi-extensive or extensive outdoor production systems in the “Montado” (green and cork oak forest), grazing and feeding acorns and other associated food resources. Bacteria of the genus Aeromonas are considered as emerging pathogens of importance for man and animals, but its involvement in swine is not well documented. In the context of a study made at the University of Évora to assess the specific diseases of Alentejano swine, diseased piglets from two farms were submitted for pathological and bacteriological examinations. Pathological examinations revealed changes characteristic of septicemia, and Aeromonas hydrophila was isolated in pure culture from multiple organs of piglets from both farms. Antibiotic sensitivity tests showed that the isolates from one of the farms were susceptible to gentamicin, oxitetracycline, neomycin, enrofloxacin, colistin sulfate, trimethoprim, ceftiofur, and amoxicillin plus clavulanic acid. In contrast, the A. hydrophila isolated in the other farm was resistant to all drugs tested but enrofloxacin. This is the first report in the world showing the relationship between septicemia and A. hydrophila infection in piglets. The importance of this finding is further reinforced by the fact that these bacteria can be highly resistant to antimicrobial agents.

Fatores de virulência em Aeromonas hydrophila causadora de septicémia em leitões

This work aims to contribute to determine the resistance profile to different antibiotics (ampicillin, gentamicin, penicillin G, oxytetracycline, lincomycin, neomycin, streptomycin, enrofloxacin, colistin sulfate, trimethoprim, sulfamide, tulathromycin, ceftiofur, amoxicillin/clavulanic acid), to assess genetic determinants associated to aminoglycoside antibiotics resistance, namely the presence of genes encoding acetyltransferases (AAC), phosphotransferases (APH) and nucletildiltranferases (ANT), determined by PCR studies, and to search for potentially pathogenic features as the production of extracellular lipases and proteases and the presence of genes encoding for putative virulence factors as aerolysin and related toxins, lipase proteins and type III secretion system component.

A enfermagem comunitária na transição para a parentalidade - visita domiciliária de enfermagem no puerpério

Atualmente, com a alta precoce após o nascimento emerge a necessidade de cuidados domiciliários no puerpério. A pertinência deste projeto consubstancia-se na reorganização da visitação domiciliária no puerpério na USF Salus, garantindo a continuidade de cuidados após a alta hospitalar. O desenvolvimento do projeto teve por base as necessidades identificadas pelos enfermeiros da USF Salus. Teve como finalidade promover a parentalidade positiva, contribuindo para a melhoria da saúde e bem-estar das puérperas, recém-nascidos e respetivas famílias, definindo-se como objetivo geral: Reorganizar a Consulta de Enfermagem do Puerpério no Domicílio, de forma a promover a parentalidade positiva nos pais com crianças até 3 meses de idade, utentes da USF Salus, até 2016. Neste relatório é feita uma análise reflexiva sobre a visita domiciliária no puerpério e apresentada a proposta de protocolo de atuação na mesma. A avaliação do projeto na perspetiva das puérperas e dos enfermeiros legitima a relevância do mesmo na criação de soluções práticas para um problema concreto; ABSTRACT: Today, with early discharge after birth emerges the need for home care in the postpartum period. The relevance of this project is consolidated in the reorganization of home visitation puerperal at USF Salus, ensuring continuity of care after discharge. The project development was based on the needs identified by nurses USF Salus. It aimed to promote positive parenting, helping to improve the health and well-being of mothers, newborns and their respective families, defining the general objective: Rearrange the Puerpério of Nursing Consultation at Home, in order to promote positive parenting in parents with children up to 3 months of age, users of USF Salus, 2016. This report is made a reflective analysis of the home visit puerperal and presented the proposed action protocol in it. The project evaluation from the perspective of mothers and nurses legitimizes the importance of it in creating practical solutions to a specific problem.
