تم تطبيق طريقة الترسب الجرثومي فوق الأوساط الجرثومية الصلبة لكشف انتقال الجراثيم مع الهواء بواسطة القطيرات و الغبار العضوي بين حظائر الدواجن في بعض مزارع دجاج اللحم و البيض بعد تحديد مستوى الحمولة الجرثومية ضمن الحظائر. لوحظ في هذه الدراسة أن أغلب المزارع المدروسة لم تطبق شروط الرعاية و التربية الصحيحة من ناحية التهوية و الخدمة مما أثر ايجاباً على نمو و تكاثر الجراثيم و ازدياد الحمولة الجرثومية و تناسب مستوى التلوث طرداً مع ارتفاع درجات الحرارة و الرطوبة بالنسبة لبعض الجراثيم و منها الجراثيم العنقودية و العقدية. كما بينَّت النتائج في تصنيف العزلات تبعاً لاختبارات الـ API انتماء الجراثيم للمكورات العنقودية ((Staphylococcus xylosus, Staphylococcus aureus و العصيات القولونية Escherichia coli و الهيموفيلس (Homophilesparagallinarum). كما سُجّل انتقال للعدوى و تشخيص إصابات مرضية متوافقة مع العزلات الجرثومية من هواء البيئة المحيطة بقطعان الدواجن في الحظائر المتجاورة ضمن المزارع المدروسة.
Bacterial deposition method was applied over hard to detect microbial community transmission of the germs with air by droplets and dust combine in some poultry farms chicken broiler and hen layer after determining the level of the microbial load in the barns. - Observed in this study that most of the farms studied the conditions did not apply the proper care and education in terms of ventilation and servicewhich impact positively on the growth and reproduction of bacteria and increased bacterial load and fit the level of contamination parcels with high temperatures and humidity for some bacteria, including Staphylococcus and Streptococcus. - As results showed in the classification of isolates according to the api that tests for Staphylococcus aureus bacteria (Staphylococcus xylosus Staphylococcus aureus), Escherichiacoli and (Homophilesparagallinarum) Also transmission of infection and diagnosis of injury satisfactory bacterial isolates from compatible ambient air in poultry flocks in adjacent pens in farms.

The study of the microbiological pollution of the air of some poultry
farms located in the central region of Syria has been conducted in this research.
Six poultry farms have been chosen, three of them are located in the south
western of Homs governorate and the rest are in the west of it..
The objective of this study was isolate and identify bacteria which was carried
mechanically and biologically on house fly (Musca domestica )in poultry and animal farms
.in this study samples of M. domestica were collected from 6 farms of animal fa
rms in
different areas of Latakia .
Bacteriological laboratory tests were conducted for (80) samples of M. domestica
and (10) samples of dead bird . bacterial cultures on selective or general environments
showed different strains of micrococcus (Staphylococcus spp. ,Enterococcus spp.) and
Bacillus (Pasteurella spp. , E.coli , Salmonella spp. , Pseudomonas spp.) these species were
further classified using the API kit system .
API tests was showed entrant isolations between house fly and ill birds which
important in disease locality : Salmonella choleraes, Staphylococcus aureus, E.coli,
klebsiella pneumonia.
The antibacterial activity of Inula viscosa L. leaves extracts against some pathogenic bacteria, which were isolated from Al-Assad hospital laboratory in Lattakia, was tested by disc diffusion method.
Results showed that water extracts had antibacte
rial activity against all Gram positive and negative bacteria. The diameters of inhibition zones were between 9 mm against Pseudomonas aeroginosa and 41 mm against Proteus vulgaris.
All Gram positive bacteria showed sensitivity to all organic extracts, so they had antibacterial activity, while Gram negative bacteria showed resistance to chloroform extract except for the one of Klebsiella pneumoniae with an inhibition zone of 12 mm, and resistance for dichlormethan extract except for Pseudomonas aeruginosa with an inhibition zone of 15 mm. there was resistance for diethyl extract except for Serratia marcescens with an inhibition zone of 32 mm.
Ethyl acetate extract had antibacterial activity against all bacteria. Ethanol, methanol and acetone extracts showed antibacterial activity against all bacteria except for Escherichia coli with an inhibition zone of 10 mm.
This study indicated that water and organic Inula viscosa L. leaves extracts had antibacterial activity against pathogenic bacteria which also was tested, especially water extract, ethanol, methanol, ethyl acetate and hexane extracts. So the Inula viscosa L. leaves extracts may be sources for natural antibiotic in future.
This research was conducted at the Faculty of Agriculture, Department of
Food Science laboratories to isolate lactic acid bacteria from some Syrian milk
products (milk, yogurt, cheese) and determine some morphological,
physiological characteristic and the ability of these isolates to ferment sugars.
- The objective of this study was to assess the level of air
contamination by bacteria in the broiler houses in salamieh region
that Famed of commercial breedings of broiler and relationship
with some impact factors like (birds age- season-breedin
g system -
dust concentration) .
- The numbers of bacteria (mesophile , staphylococci , streptococci
and gram-negatives) and dust concentration were determined in 5
opened broiler houses and 5 closed broiler houses with chicken
houses in different ages (1-6 weeks old) in summer and winter .
