This study was carried out to detect the bacteria which caused Carp
Erythrodermatitis in the governorate of Hama, by using bacterial
isolation ,and polymerase chain reaction (PCR) , the bacterial species
were defined by biochemical Tests
Pyocyanin was extracted from cultures of Pseudomonas
aeruginosa, which was isolated from sea water by chloroform.
Results study the effect of pyocyanin against human pathogenic
bacteria, which were isolated from Al-Assad hospital laboratory in
La
ttakia, with disk diffusion method showed that pyocyanin has
antibacterial activity against Gram- positive bacteria.
In August 2015 the collected leaf of Arctostaphylos uva-ursi were
gathered. Then the volatile oil from fresh samples was extracted
with n-hexane and other samples with steam distillation.
The red meat is one of the main group of food due to their high
content of protein , mineral salts , vitamins . But the high content of
humidity and its pH value that is suitable to growth of most
microorganisms make it subject to spoilage .
In t
his study different samples of commercial meat which were
taken from market in Homs , were valuated by microbial analysis
and that were done for fresh samples , and after one month of frozen
storage in home .
The study indicated that the most of commercial red meat , were
unacceptable to human consumer because the total number of
Aerobic Bacteria , Listereia, Staphylococcus Aureus , Salmonella ,
E. coli , were unacceptable to Syrian Arab Organization for
Standardization that may be due to disases of animale or the
contamination that was happened during dealing from farm to
consumer .
Two bacterial species were isolated from petroleum hydrocarbon-contaminated soil.
The isolates were characterized based on their gram reaction characteristics, morphological
and biochemical properties.
The results showed two bacteria isolated the
first isolated: gram negative short rod,
urease and nitrate reduction test showed a positive result , and glucose test showed positive
result.
And the second isolated: gram positive cocci, gelatin and Citrate utilization test
showed a positive result , and maltose, mannitol test showed negative result.
They were then incubated at (37) ° C for (48- 72) hours.
This is based on comparison of results with Bergey Manual of systematic
bacteriology.
The isolates were identified to be: Pseudomonas pachastrellae (X1)
Micrococcus brunensis (X2).
أجري هذا البحث بهدف التحري عن بكتريا العصية الشمعية وعزلها من بعض الاغذية المحلية الجاهزة للأكل ( المقبلات الغذائية ) كمتبل الباذنجان والحمص بالطحينية والسلطات الجاهزةوالنودلز المباعة في الاسواق السورية
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 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.
A clinical trial cross over was carried out to compare the clinical effectiveness of the use of conventional toothbrush (Oral-B Indicator Plus) and (Soladey-eco) which is equipped with a rod of semiconductor of titanium dioxide (TiO2) to remove dent
al plaque and their impact on Streptococcus mutans counts (CFU) .
The Sample included 60 patients aged 13-19 years. The sample was equally divided into two groups: the first group used toothbrush (Oral-B Indicator Plus) and the second used toothbrush (Soladey-eco) twice daily for one month, followed by (wash out) period for two weeks, after which the exchange of the two groups for the two types of brushes, the examiner was blind.
To determine the effectiveness of the two brushes, the dental plaque index was calculated for every brush before and after brushing. The S .mutans (CFU) in saliva was calculated too but just for (n=30) before and after brushing.
Results showed that the use of the brush (Soladey-eco) has greater effectiveness in removing dental plaque and caused a reduction of Streptococcus mutans counts compared with the brush (Oral-B Indicator Plus) in the research sample
Proteus volgaris was isolated from costal sea water of Lattakia city port, as it is contaminated with petroleum compositions coming from marine transportations activities. The ability of this bacteria to degrade the petroleum alkanes was studied by
using different concentrations of petroleum as sole source of carbon and energy. The gas chromatography (GC) technique was used to measure the concentration of alkanes. Results showed that the isolated bacteria were able to degrade different alkanes chains. The ratio of biodegradation of C12, C16, C18 were 96.75%, 78.59%, 97.27% respectively, while the rate of biodegradation of the entire amount of alkanes was 77.14% in 10 mg/ml polluting concentration. The percentage of biodegradation at concentration 75 mg/ml of petroleum was 17.26%.
Therefore, the high ability of Proteus volgaris to degrade the long chains alkanes recommended it to be effective in the bioremediation process of the contaminated marine environments.
