Phylogenetic Diversity of Aeromonas from “Alheira”, a Traditional Portuguese Me...
Fontes, M. C.; Martins, C.; Martínez-Murcia, A.; Saavedra, M. J.“Alheira” is a traditional smoked meat sausage produced in the north of Portugal, representing an important economic resource for the region. Eventually, this meat product has been subjected to research studies with the aim to detect the presence of common foodborne pathogens but, to our knowledge, isolation of emerging foodborne Aeromonas from “alheira” has never been previously described. Present work attempt...
Laboratory limits on dermatophyte diagnosis in rabbits with clinical lesions
Coelho, A.C; Pinto, M.L; Coelho, A.M; Fontes, M.C; Mourão, J.L; Pinheiro V.Mermatophyte infection or ringworm is a superficial cutaneous infection with one or more of the fungal species of the keratinophilic genera Microsporum, Trichophyton, or Epidermophyton and is a zoonosis with a great impact on public health. Dermatophytes were identified from rabbit sample cultures submitted to mycological examination in the Laboratory of Microbiology of the University of Trás-os-Montes e Alto Do...
Phylogenetic identification of Aeromonas from pigs slaughtered for consumption ...
Fontes, M. C.; Saavedra, M. J.; Martins, C.; Martínez-Murcia, A.In the present study, 710 isolates of Aeromonas spp. have been collected from pig carcasses, diaphragm muscle, faeces, dehairing equipment and water in slaughterhouses at the North of Portugal. The isolates were obtained from a total of 154 samples. All Presumptive Aeromonas isolates were subjected to ERIC-PCR analysis and those which presented a different pattern were taken and the species classified by gyrB g...
Phylogenetic identification of Aeromonas simiae from a pig, first isolate since...
Fontes, M.C.; Saavedra, M.J.; Martins, C.; Monera, A.; Martínez-Murcia, A.The species Aeromonas simiae was first described on the basis of two strains (CIP 107798T and CIP 107797) isolated from faeces of healthy monkeys (M. fascicularis) from Mauritius, which were kept in quarantine in the Centre for Primatology, Louis Pasteur University, Strasbourg, France. In the present study, during a survey to determine the prevalence of Aeromonas at three different pig slaughterhouses at north ...
Diversity of serine-ß-lactamase genes among Aeromonas isolates from pigs slaugh...
Fontes, M. C.; Martínez-Murcia, A.; Martins, C.; Saavedra, M. J.Introduction: Antimicrobial resistance in foodborne pathogens has become a public health issue. The intense and indiscriminate use of antibiotics is undoubtedly the major force associated with the high bacteria resistance worldwide. Some Aeromonas species cause both gastrointestinal and extraintestinal infectious diseases in humans. Many studies suggest members of Aeromonas developed multiple antibiotic resista...
Detection of Metallo-ß-lactamases in Aeromonas isolated from alheira: a tradici...
Fontes, M. C.; Martínez-Murcia, A.; Martins, C.; Saavedra, M. J.Introduction: Members of the genus Aeromonas are facultative anaerobic gram-negative rods, oxidase-positive that are widely distributed in aquatic environments and have also been isolated from different kinds of food. Gastroenteritis is considered the most common Aeromonas clinical presentation. Susceptibility patterns of these species revealed an increase in resistance to ß-lactam antibiotics, which is attribu...
Laboratory limits on dermatophyte diagnosis in rabbits with clinical lesions.
Coelho, A.C; Pinto, M.L; Coelho, A.M; Fontes, m.C; Mourão, J.L; Pinheiro, V.M; Rodrigues, JDermatophyte infection or ringworm is a superficial cutaneous infection with one or more of the fungal species of the keratinophilic genera Microsporum, Trichophyton, or Epidermophyton and is a zoonosis with a great impact on Public Health.

Antimicrobial resistance and resistance genes in Aeromonas isolated from “alhei...
Fontes, M. C.; Saavedra, M. J.; Martins, C.; Martínez-Murcia, A. J.Aeromonas are autochthonous species in aquatic environment and have also been isolated from different kinds of foods, including those of animal origin, seafood and vegetables. Some species are considered important pathogens and water and foods are important sources of transmission of Aeromonas spp.. In the present work we studied the antimicrobial resistance in strains of Aeromonas isolated from “alheira”, a tr...
Estado de frescor e qualidade higiênica do pescado vendido numa cidade do inter...
Fontes,M.C.; Esteves,A.; Caldeira,F.; Saraiva,C.; Vieira-Pinto,M.; Martins,C.Avaliaram-se o estado de frescor e a qualidade higiênica do pescado disponível em alguns estabelecimentos comerciais de Vila Real, uma cidade do interior de Portugal. Vinte e três amostras foram submetidas a uma análise sensorial e a análises fisico-químicas - determinação do teor de azoto básico volátil total (ABVT), do índice de refração do humor aquoso e do pH. A avaliação da qualidade higiênica do pescado f...
