Survey Of Microbial And Molecular Identification Of Pathogenic Microbes In Schools' Canteens
Fahad Dhaifallah Al-Shareef , Mohammad Hussein Fakieh and Mohamed Morsi M. Ahmed
Abstract: Food-borne illnesses can be passed from person to person by eating contaminated food. Microbe infections, toxic byproducts of microbes, or toxic chemicals are thought to be the root cause of diseases transmitted through contaminated food. Food is frequently spoiled and tainted by a wide range of germs in homes, restaurants, canteens, and other public places. As more cases of illnesses caused by consuming contaminated food in school canteens are reported around the world, particularly in Saudi Arabia, this article reviews various journal articles that documented bacterial foodborne illness cases in Saudi Arabian schools and other parts of the world using microbial and molecular identification of pathogenic microbes in school canteens. The purpose of this article is to improve our understanding of bacterial foodborne disease outbreaks and the health consequences of school canteens. This review discovered a variety of harmful bacteria in school canteen food, including Salmonella species, E. coli species, Shigella species, Staphylococcus aureus, Pseudomonas aeruginosa, Clostridium species, Vibrio cholera, Bacillus cereus, and others. This study contributes to the improvement of staff members' knowledge of food contamination in school canteens. This research helps to increase awareness among students of the factors that may contribute to the transmission of food-borne pathogens and the subsequent outbreak of foodborne diseases. To reduce the risk of illness caused by foodborne pathogens, all canteen employees and operators must know the necessary to effectively control all aspects of food quality and safety.

The effects of vitamin D on cardiovascular health
Khadeejah Alsolami, Mohammed Alsolami, Muath Amisbahi
Abstract: Although vitamin D and its metabolites were originally discovered to aid in calcium and bone homeostasis, the discovery that vitamin D receptors are expressed in virtually all human tissues suggests that vitamin D may play a direct or indirect role in many physiological processes. Strong evidence for vitamin D's role in cardiovascular health comes from the expression of vitamin D receptors and the presence of enzymes involved in vitamin D metabolism in the vasculature and the heart. Vitamin D deficiency and the risk of cardiovascular disease have been the subject of numerous observational studies, but this is still an area that needs more research. Multiple cross-sectional studies have found a correlation between low vitamin D levels and various cardiovascular diseases and risk factors like hypertension, heart failure, and ischaemic heart disease. Preliminary prospective studies show that patients with a history of cardiovascular disease have a higher risk of developing hypertension and dying suddenly. There is a dearth of clinical trials reporting the effect of vitamin D supplements on cardiovascular diseases. This article provides a summary of the literature describing vitamin D's correlation with cardiovascular disease and its effect on cardiovascular outcomes like mortality.
