Article Synopsis
- The study focused on Group B Streptococci (GBS), a significant risk for neonatal infections, examining its prevalence and antibiotic resistance in pregnant women in Nigeria.
- In 87 pregnant women, the prevalence of GBS colonization was found to be 43.6%, with a notably high resistance to erythromycin and vancomycin at 48.2% and 66.4%, respectively.
- The majority of GBS isolates were strong biofilm producers and there was a high rate of multidrug resistance (MDR) detected, highlighting the need for testing antibiotic susceptibilities in pregnant women to improve treatment and reduce newborn infections.
Article Synopsis
- The study investigates tick populations in South Africa and their potential risks to human and animal health due to tick-borne diseases.
- Morphological and molecular techniques were used to analyze 1,200 tick samples from domestic animals, identifying eight tick species and confirming 27% positive for certain bacteria.
- Results showed that these ticks could harbor zoonotic species, highlighting a significant health risk that has been underreported in the region.
The expected progress in SARS-CoV-2 vaccinations, as anticipated in 2020 and 2021, has fallen short, exacerbating global disparities due to a lack of universally recognized "safe and effective" vaccines. This study focuses on extracts of South African medicinal plants, and , to identify metabolomic bioactive compounds inhibiting the binding of the SARS-CoV-2 spike protein to ACE2 receptors. The extracts were monitored for cytotoxicity using a resazurin cell viability assay and xCELLigence real-time cell analyzer.

Due to their biofilm-producing capacity and the increasing antimicrobial resistance in this microorganism, this study aimed to determine the prevalence, biofilm-producing capacity, antimicrobial resistance patterns, multidrug resistance and plasmid mediated resistance of the recovered isolates. <b>Materials and Methods:</b> A total of 50 urinary samples were collected from May to August, 2018 from patients on indwelling urinary catheters.

Retail meat samples (n = 176) collected from four shops (two from open-air markets and two from closed stores) were analyzed by conventional biochemical and PCR-based molecular confirmatory tests. The confirmed isolates were profiled for antimicrobial susceptibility to a panel of 12 commercial antibiotics: tetracycline, ampicillin, sulphamethoxazole trimethoprim, erythromycin, gentamycin, colistin sulphate, cefotaxime, chloramphenicol, norfloxacin, ciprofloxacin, cefuroxime, and imipenem.
