تم تحليل 73 عينة مياه شرب من شبكة التوزيع العام في مدينة اللاذقية بهدف الكشف عن الجراثيم غيريات التغذية و دراسة مقاومتها للكلورين و للصادات الحيوية. اختبرت حساسية الجراثيم المعزولة تجاه عشرة صادات حيوية بطريقة التمديد في الآغار (طريقة MIC) و الصادات الحيويـة المـستخدمة هـي: امبيسيللين، كلورامفينيكول، تتراسكلين، اميكاسـين، سيبروفلوكـساسين، سيفوتاكـسيم، جينتاميـسين، اريثرومايسين، بيبراسيللين/ تازوباكتام، سيفالوتين. تم عزل 133 سلالة جرثومية توزعت على الأجناس الجرثوميـة الآتيـة: زوائـف, ايرومونـاس, اسينيتوباكتر، كروموباكتر، فلافوباكتر، ميتيلوباكتر. ترواح محتوى العينات من الكلورين المتبقـي بـين 1.0 ملغ/ل و 8.3 ملغ/ل. أظهر القسم الأعظم من الجراثيم المعزولة مقاومة مختبرية للكلورين بالإضـافة إلى مقاومة مرتفعة للصادات الحيوية المستخدمة.
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.
