Inhibition activity of extracts (acetone, ethanol, water) parts of the (Myrtus
communis L.) (root, stem, leaves, fruits) with concentrations (25,50,75,100%)
was carried out against growth of Gr- and Gr+ bacteria which were isolated and
identified
from the pathogenic specimens of The University Children's Hospital
bacterial laboratory in Damascus, using agar well diffusion method on Mueller
– Hinton medium.
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.
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.
A total of 370 bottles of noncarbonated natural mineral water (domestic and
imported) with different bottling dates, were collected directly from the
markets in Syria one word one year 2006.
Bacterial diversity was approached with tentative
identification of the strains isolated using biochemical and enzymatic criteria
(with the aid of API 20 NE identification system for nonfermenters).
Symptoms of soft rot showed in some fields cultivated with garlic crop in the
Kissweh region (Damascus countryside). Studying this disease, found that the
incidence rates ranging between 2.91% to 5.59%. 55 bacterial isolates were
isolated from inf
ected samples collected during the seasons 2005 and 2006. The
results of five biochemical tests showed that 22 isolates were pectinolitic and
they were pathogenic to garlic plant and gave symptoms similar to those
observed in the field, theses isolates were classified as belonging to the genus
Pectobacterium. To determine the species of the bacteria, they have been
characterized towards nine biochemical tests, which allowed the classification
of 7 isolates as Pectobacterium carotovorum subsp. carotovorum, 6 isolates
belonged to Pectobacterium atrosepticum, one isolate to Dickeya chrysanthemi
(Pectobacterium chrysanthemi), 6 isolates have not been classified and 2 isolate
did not characterized . These results have shown for the first time the isolation
and identification of the Pectobacterium bacteria causing soft rot on garlic crop
in Syria.
Isolation and identification of Pseudomonas aeruginosa was screened from
15 samples of Syrian oily-soils to determine the ability to produce Lipase
enzyme by Cetermide Agar, Tributrin Agar and Brain Heart Broth during
2007-2008 AD. The results sho
wed that there were grown colonies with color of
green or yellow-green surrounded with different diameter of clear zone in three
samples and the identification by Mowasat Hospital revealed that it was
Pseudomonas aeruginosa In addition, the results showed that the optimum
conditions to produce lipase was 35 Cº with the pH degree of 8 and the time of
production of lipase with highest activity of 63.3% was three days in
submerged culture during the optimum conditions. These results illustrated the
important of this isolates to produce and control lipase for industrial
production.
Olive trees are grown in many regions of Syria, especially in wet regions
where the olive knot disease (Pseudomonas savastanoi pv.savastanoi ) prevails
.Symptoms similar to those found on olive trees have been observed on myrtle
shrubs (Myrtus com
munis) growing naturally in some olive-grown regions. This
study aimed at identifying the pathogen isolated from myrtle plant, and testing
the pathogenicity of these isolates on olive trees. Morphological, biochemical
and serological tests of bacteria isolated from myrtle showed similarity to
those from olive and other hosts. Pathogenicity tests showed that the myrtle
isolates were pathogenic on both myrtle and olive trees. Myrtle could be
considered as a source of inoculum for the olive knot disease.
We screening for antimicrobial substances production from marine algae of
Syria. We presented results of ١٦ algal species tested by their lipide and
aqueous extracts agaimst Gram’s negative and positive bacteria, as well as one
fungous species.
T
he lipide not aqueous extracts were the active against Gram’s positive
bacteria especially.
No effect founded on the fongous species. In addition we make comparative
viewing with other studies on other mediterranean contries regarding the same
species of algae tested.
The objective of this research was to study the causes , symptoms
and diagnosis of otitis externa in cats, and to investigation the effect
, breed, season on the rate of affection in the veteriniary faculity in
hama university.
The number of case
s was( 346) wich was broght to the
veterinary teaching hosbital in Hama university and from special
clinics.
