Antimicrobial and antioxidant activities of Citrus sinensis var. late Valencia fruits at various stages of development

Fruit juice extracts of Citrus sinensis var. late Valencia at different stages of development (3, 6, 10 and 12 months and fallen senescent fruits) were investigated for antimicrobial and antioxidant activities. Antimicrobial activity was determined using a modified Kirby-Bauer agar diffusion method and minimum inhibitory concentrations (MIC) were determined by the micro broth dilution method against strains of Bacillus...

Biopeptides with antioxidant activity extracted from the biomass of Spirulina sp. LEB 18

The microalga Spirulina has been marketed in many countries due to its application in foods, especially for its high protein content, which can be used to obtain protein hydrolysates. Protein hydrolysates are easily absorbed by the gastrointestinal tract and have significant physiological properties, because during the hydrolysis process, peptides with antioxidant activity can be obtained. The objective of this study...

Serological survey of foot and mouth disease virus antibodies in apparently healthy domestic pigs in Nigeria

Despite the endemic nature of foot and mouth disease (FMD) in Nigeria, little is known about the epidemiology of the disease in pigs. FMD could pose a negative economic and social impact in the life of small-holder and commercial pig farmers in the advent of an outbreak. In this report, out of 822 pig sera collected from two states (Plateau and Enugu) in Nigeria, 12 (1.5%) tested positive for antibodies to the highly...

Presence of Helicobacter DNA in hepatic tissues in dogs with nonspecific hepatic lesions

Infection of the gastric mucosa by Helicobacter spp. is an important cause of gastric diseases and neoplasms in humans and animals. The objective of this study was to evaluate the presence of Helicobacter spp. in the livers of dogs with nonspecific histological changes. The association between Helicobacter spp. infection, hepatocyte proliferation and E-cadherin expression was also evaluated. Liver samples from 39 dogs...
