Abstract

After a year of COVID-19 being distributed in all countries worldwide, several COVID-19 vaccines were invented by different companies. All of these vaccines got emergency approval from WHO because of critical conditions to fight this pandemic, but still, scientists work on clinical experiments to approve the safety of these vaccines and their adverse effects. This research tried to check the safety of vaccines imported from the Libyan Health Ministry. The comparison was among Sinovak, Sinopharm, AstraZeneka, Sputnik V, and Pfizer- BioNTech vaccines. The research aimed to compare the side effects of each vaccine after 24 hours of vaccination, this information was collected from people who work or study at Misurata University. The first notice of survey results was the small number of people who took the second dose of all vaccines, even if all second doses have been provided by the health ministry with the exception of sputnik V. Most side effects were clear in sputnik V, AstraZeneka, and Pfizer- BioNTech, on the other hand, Sinopharm and Sinovac were mostly with little side effects although some people had headache and fever. This research recommends for more action forward campaign that aims to convince Libyan people to get COVID-19 vaccines.

Abstract

Tuberculosis (TB) remains a major global health problem, exacerbated by the emergence of multidrug-resistant strains. Bacteriophages, particularly lytic phages, are gaining increasing attention as alternative antimicrobial agents due to their specificity and low resistance potential. This is a pilot study aimed at isolating lytic bacteriophages from hospital and domestic wastewater that exhibit activity against Mycobacterium smegmatis (M.sm) as a model organism for Mycobacterium tuberculosis (M.tb). Wastewater samples were collected from five locations and tested for lytic activity using a spot test on M.sm. The results confirmed the presence of phages in four of the five samples, as evidenced by plaque formation with varying morphology. Plaques from samples coded ABR and ABM were mostly clear and large, indicating strong lytic activity, while samples coded IS and VB showed more diverse plaque shapes, including turbid and small plaques. This difference reflects the influence of environmental origin on phage diversity. The highest plaque diversity was observed in samples with high organic content and microbial richness, supporting the hypothesis that phage-host interactions are shaped by environmental factors.
