Effect of Piper nigrum, Thymus vulgaris and Syzigiuim aromaticum essential oils on the microbiological and sensory quality of Pork sausages during preservation

The use of essentials oils (EOs) as alternative of nitrites and nitrates in sausages will be proposed in this study. For this purpose, the minimal inhibitory concentration (MIC) of white Piper nigrum of Penja, Thymus vulgaris and Syzigiuim aromaticum EOs were determined in vitro against Escherichia coli ATCC25922, Salmonella enteritidis 155A and Staphylococcus aureus NCTC10652. It follows from this study that, T....

Prevalence of rotavirus group A and associated genotypes detected in calves in Southern Highlands and Eastern Tanzania

Rotavirus group A (RVA) causes neonatal calves diarrhoea, causing massive economic losses in many countries due to deaths, treatment costs, and stunted growth. However, little is known about Tanzanian cattle's RVA burden and genotypes. The prevalence and genetic diversity of rotaviruses circulating in cattle in Southern and Eastern Tanzania regions were investigated. A total of 272 faecal samples collected from...

16S rRNA gene sequence analysis of the microbial community on microplastic samples from the North Atlantic and Great Pacific Garbage Patches

The exponential increase in plastic production has led to their accumulation in the environment, particularly in oceans, polluting these environments from the shore to the open ocean and even sea ice in the pole regions. Microbial communities were compared on plastic particles, known as "Plastisphere", collected from the Atlantic and Pacific ocean gyres in the Summer of 2019 and subsequently inspected for...
