Abstract
Water sources contamination is nearly always the result of human activities and drinking water source is especially vulnerable in areas where population density is high and human use of the land is extensive. When water sources become contaminated, it is difficult to purify. Liquid waste discharged on to the soil initiates solute and microbe movements are the main source that contaminates water sources. Thus far, there are no records of any studies in which Vibrioes contaminations have been studied in aquatic environment in Yemen, so in the present study, we tried to isolate vibrioes in Thiosulfate citrate bile salt media (TCBS) selective media from different sources of drinking water, in addition from swages system in Sana’a city.
Highlights
Members of the genus Vibrio cause a number of important infectious syndromes
We conclude from this study that, the prevalence of Vibrio cholerae in drinking water sources and sewages in Sana’a city was zero, while others Vibrioes as V. algenolyticus and V.fluvialis were isolated
The prevalence rate of other pathogenic bacteria species that transmitted through water ingestion in drinking water sources was high which indicate human fecal contamination of water sources
Summary
Members of the genus Vibrio cause a number of important infectious syndromes. Classic among them is cholera, a devastating diarrheal disease caused by V. cholerae that has been responsible for seven global pandemics and much suffering over the past two centuries. Other Vibrioes caused by other Vibrio species include syndromes of diarrhea, soft tissue infection, or primary sepsis. All Vibrio species are highly motile, facultative anaerobic, curved gram-negative rods with one or more flagella. Vibrioes most commonly reside in tidal rivers and bays under conditions of moderate salinity. They proliferate in the summer months when water temperatures exceed 20°C. The illnesses they cause increase in frequency during the warm months [2,3]
