Abstract

Characterized by this study show the close connection between the components of Lake Saveh and the population density of the types of microbes present and depending on the circumstances surrounding the results indicate that the highest temperature of the air and water recorded at the station (1) during the month of November (22 m) This is consistent with the results of counting of bacterial , which showed the highest value reached (89 × 10-6) during the same month was because of the presence of phytoplankton and the accumulation of organic materials that are food items important to germs at this temperature , which varied compared with the preparation of the bacteria in the months developed and characterized by lower temperature ( 14-19 m) ​​. As noted coincided high basal with a higher total number of bacteria . Showed results and depending on the diagnostic tests that (58%) of the total bacteria, during the month ( December , January , February ) is a bacterium E. coli while ( 33%) due Bacillus spores and during the months ( November , December ) and (5% , 4%) to Gerthomta Klebsiella , Pseudomonas , respectively, and during the month ( February ) . It also showed the results of screening sensitivity microbial direction antibiotics qualitative differences in the resistance and by type of bacteria showed all isolates high sensitivity direction Naldixic acid and by ( (92% and Gentamicin by ( 83% ) and Chloromphenicol by ( 100%) while expressing the sensitivity of medium and low for the rest of antibiotics Ceftizoxime such a rate (42%) and Aztreonam (50% ), while some showed poor sensitivity such as antibiotics Ticarcilin by ( 8%) and Cefinase by ( 28% ) while not showing any sensitivity to certain antibiotics such as penicillin and Amoxicillin.
