Effect of mannan oligosaccharides on the performance, intestinal morphology and...

A common problem in rabbits is the occurrence of digestive disorders just after weaning. This problem is associated with instability of the cecal microflora and characterized by diarrhea, loss of appetite and increased mortality. In the current study the effects of mannan oligosaccharide (MOS, Bio-Mos®, Alltech Inc., USA), a natural growth promoter, were compared to a commonly used antibiotic growth promoter (A...

Effects of olive leaf on gut microflora of broiler poultry

In 2006 European Union bans the use of antibiotics as growth promoters (AGP) in animal feed. Due to the fact that the use of antibiotics as growth promoters has been banned intensive research has focused on the development of alternative strategies with the aim of maintenance of animal health and performance. Some studies showed that olive leaves have specific organic compounds with antimicrobial activities. Th...

Antagonistic activities of Kefirgel and Kefirgel products against Staphylococcu...

Diabetic foot ulcers are often complicated by infection and among pathogens the Gram-positive Staphylococcus aureus is the most common isolated. Also concomitantly, the high prevalence of methicillin-resistant S. aureus (MRSA) was significant impact on successful treatment of infected foot ulcers. In this context, the purpose of the present study was to evaluate the antibacterial properties of Kefigel®, a natur...

Antibacterial screening of active ethanolic fractions of Urtia dioica L. agains...

Medicinal plants are largely explored source of drug repository. Although a huge number of antibiotics are available for treatment of microbial infections, development of resistance mechanism against antibiotics is nowadays a major health concern. Therefore the needs of discover new antimicrobial compounds with high safety index is always recurrent and medicinal plants have great potential for providing novel d...

Phylogenetic Diversity of Aeromonas from “Alheira”, a Traditional Portuguese Me...

“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...

Phylogenetic identification of Aeromonas from pigs slaughtered for consumption ...

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...

Seasonal effects on bioactive compounds and antioxidant capacity of six economi...

Research on natural and bioactive compounds is increasingly focused on their effects on human health, but there are unexpectedly few studies evaluating the relationship between climate and natural antioxidants. The aim of this study was analyze the biological role of six different Brassica vegetables (Brassica oleracea L. and Brassica rapa L.) as a natural source of antioxidant compounds. The antioxidant activi...

Susceptibilidade a antibióticos em isolados bacterianos do ambiente em lares de...

O envelhecimento populacional traz um número vasto de implicações que incluem, entre outras, condições de baixa imunidade e por isso maior risco de infecções. Algumas situações podem contribuir para aumentar esse risco, nomeadamente má ventilação, aglomerado populacional, condições de humidade e fraca higienização. O tratamento das infecções passa pela administração criteriosa de antibióticos. A identificação ...

Potential virulence factors of Candida spp. isolated from clinical and food sou...

Phylogenetic identification of Aeromonas simiae from a pig, first isolate since...

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 ...
