This study was carried out to evaluate the microbial contents of chicken eggs, sold at retail outlets in Sokoto metropolis. A total of 160 eggs were collected from 16 randomly selected retail outlets, in Sokoto metropolis, for microbial evaluation. Samples were cultured and isolated using nutrient and McConkey agar for bacteria while Sabauroud dextrose agar was employed for fungus and identifie...

During the Integrated Ocean Drilling Program (IODP) Expedition 331 at the Iheya North hydrothermal system in the Mid-Okinawa Trough by the D/V Chikyu, we conducted microbiological contamination tests of the drilling and coring operations. The contamination from the drilling mud fluids was assessed using both perfluorocarbon tracers (PFT) and fluorescent microsphere beads. PFT infiltration was d...

Research interest in microbial biodiversity over the past 25 years has increased markedly as microbiologists have become interested in the significance of biodiversity for ecological processes and as the industrial, medical, and agricultural applications of this diversity have evolved. One major challenge for studies of microbial habitats is how to account for the diversity of extremely large a...

Introduction: Maintaining good oral hygiene is an important factor in health.Toothbrushes are commonly used to maintain oral health and prevent dental disease, but unfortunately how keeping the toothbrush is neglected . The aim of this study was to investigate the relationship between toothbrush keeping method and its microbial content. Methods: In this cross-sectional study, 60 volunteers w...

MOTIVATION PCR amplification of highly homologous genes from complex DNA mixtures is known to generate a significant proportion of chimeric sequences. Ribosomal RNA genes are used for microbial species detection and identification in natural environments, and current assessments of microbial diversity are based on these sequences. Thus, chimeric sequences could lead to the discovery of non-exis...

The objective of this study was to assess the impact of metal contamination on microbial functional diversity and enzyme activity in forest soils. This study involved the evaluation of the influence of the texture, carbon content and distance to the source of contamination on the change in soil microbial activity, which did not investigate in previous studies. The study area is located in south...

The microbial safety of foods continues to be a major concern to consumers, regulatory agencies and food industries throughout the world. Many food preservation strategies have been used traditionally for the control of microbial spoilage in foods but the contamination of food and spoilage by microorganisms is a problem yet to be controlled adequately. Although synthetic antimicrobials are appr...

The objective of this study was the in vitro evaluation of the effect of a cell-free microbial supernatant, produced by a luxS-positive Salmonella enterica ser. Typhimurium strain, on the single-cell growth kinetic behavior of two strains of S. enterica (serotypes Enteritidis and Typhimurium) and a methicillin-resistant Staphylococcus aureus strain. The single-cell lag time (λ) of the pathogens...
