A total of 73 drinking water samples were collected from distribution system in Lattakia city, the aim was to search for hetrotrophic bacteria and investigate their resistance to chlorine and antibiotics. The antibiotic susceptibility tests were: carried out by using agar dillution method (MIC) and the antibiotics tested were: Ampicillin, Chloramphenicol, tetracycline, Amikacin, Ciprofloxacin, Cefotaxim, Gentamicin, Erythromycin Piperacilin/ Tazobactam, and cephalothin. A sum of 133 bacterial strains were isolated and included by five genera: pseudomonas, acinetobacter, flavobacter, chromobacter, and methylobacter. The samples content of residual chlorine were ranged between 0.1 to 3.8 mg/l. The majority of bacterial strains isolated were resistance to chlorine. The multiple antibiotic resistances were common amongst isolated bacterial strains.

Pathogenic germs have developed an increasing resistance toward many antibiotics which form a true problem for human being ,because these germs can transport to him by many ways such as water ,food and air that may cause many dangerous diseases to human being. The aim of this study is to investigate the effectiveness of extractions prepared from different parts of the flowing plants: Olea europea Linn(Oleaceae) , Myrtus communis Linn(Liliaceae) ,Majorana syriacus Linn (Laminaceae), Zingiber officinale Linn(Zingiberaceae),and Achillea falcata Linn(Asteraceae), against Pseudomonas Aeruginosa.
Water sources in Syrian coastal area have a great importance due to the variety of the sources and the urgent needs to water for drinking and irrigation. Therefore great efforts are made to protect water sources from contaminants. This research aim ed to study some contaminant indicators in some drinking water sources in the Syrian coastal area. The study included determining the concentrations of nitrates, nitrites and some heavy metals including lead, cadmium and zinc in water samples taken from five sources of water distributed from north Lattakia to north Tartous. The results showed that the concentrations of nitrate, nitrite and heavy metals differ depending on the water source. However, all these concentrations were lower and within the acceptable limits of Syrian standard for drinking water. The study concluded that water resources in the coastal area are distinguished with their relative purity and contaminants little reach.
54 isolates were isolated of the bacteria associated with ear infections which have antimicrobial resistance from the patients in the National Hospital in Qamishly City during the period from 01/08/2008 to 31/10/ 2009. The number of Pseudomonas ae ruginosa was high, followed by Staphylococcus aureus. It has been found that the rate of ear infections was lower in male (44.4%) than female (55.5%), and was (48.10%) in the first age category (1- 15 year) more than the second age category (15- 30 year) (31.37%), while the rate of ear infections was (23.5%) in the third age category(30- 60 year ). We found that all the strains of isolated bacteria showed high susceptibility to Imipenem (100%), and all bacteria of Pseudomonas, klebseilla, Proteus, Enterobacter, showed high sensitivity to ciprofloxacin, levofloxacin (85%), but only staphylococcus (58%). In addition, most isolated bacteria showed intermediate sensitivity to tobramicine, amikacine, gentamycine, and cephalosporinses like ceftazidime, cefaclor and cefotaxime. At the same time, most isolated bacteria showed resistance to Amoxicilline, Ampicillin, Penicillin, Oxacylline, Sulphamethoxasole, erythromycin, vancomycine and tetracyclines.
Fluoride ion is present in high concentration in some regions in Syria. As fluoride occurs naturally in water, We have studied some methods of fluoride removal such as Nalgonda technique and activated carbon method. In Nalgonda technique we add Al um and lime to the water, and we have found that fluoride removal efficiency remains constant when the initial concentrations of fluoride changes, or when the chloride ions exists in water, but it depends on pH, and get better when the method is investigated in two steps. In addition, adsorption of fluoride decreases with increasing sedimentation time, or using Ventilated lime or CaCO3 instead of Ca (OH)2. In activated carbon method we have done different experiments by using charcoal of coconut coir, date seeds and olive seeds. And we have found that olive seeds carbon is better than others, and its fluoride removal efficiency increases after impregnation with solution of 2% Al2(SO4)3.
This research aims to investigate the effectiveness of anti-bacteria shown by the extracts prepared from per carps of different types of Punica granatum ( L) ( from the family Punicaceae), which grow in Syria against Escherichia coli (E.coli) biotype (1), which were resistant to studied antibiotics.
