A reverse transcriptase-polymerase chain reaction (RT-PCR) technique was used
to detect infectious bronchitis virus (IBV) in the commercial broiler flocks in
Syria. 50 tissue samples were taken from tracheal tissue, trachea and kidney of
the broil
ers suspected of infectious bronchitis (IB) from different governorates
of Syria i.e. Latakia, Tartous, Hama and Damascus countryside. RNA was
extracted directly from the tissue samples and then RNA was converted to cDNA
by RT-PCR technology; PCR reaction and Nested PCR interaction were carried
out sequentially. The primers used in the RT-PCR reaction were selected from
the S1 gene (spike), where mutations of the virus genome were concentrated in
this region (the hypervariable region). Some positive samples (10) were injected
at an age of 9-11 days old SPFEE-specific pathogen free embryonated eggs
according to the methods adopted in virology. This research was carried out at
the laboratories of Latakia Research Center, General Commission for Scientific
Agricultural Research GCSAR, in cooperation with the PCR laboratory at the
Faculty of Veterinary Medicine in Hama. The results showed the existence of 37
positive case for RT-PCR (74%), and the infectious embryos showed clear and
characteristic anatomical lesions of the infectious bronchitis virus after 5-6 days
post injection, delayed and undeveloped fetal (dwarfism), fingertip entanglement
and hemorrhage compared with the negative control. The results also showed the
sensitivity and speed of the RT-PCR test in the detection of the IBV virus.
The volatile oil of Anthemis scariosa was studied in environmentally
different regions distributed on five locations in the provinces of Homs and
Hama, in order to determine the quantity and quality and effect of the
surrounding environment, on th
e volatile oil specifications. The plants
were gathered during tow phonological phases of the life of the plant
included the vegetative growth stage- the full of flowering stage. It was
then extracted through water extraction method. It was found that the
highest percentage of volatile oil was recorded in Al-hamra location
at the full of the flowering stage during the 2013 season.
This study was conducted to determine the prevalence of salmonella in the
bowels of the broiler carcass in poultry slaughterhouses in southern Syrian
governorates. 216 random samples of giblets included liver, spleen, heart and
gizzard) collected
weekly during March and September of 2011 from small
slaughterhouses in southern governorates were incubated in buffered peptone
water, selinite broth, Salmonella-Shigella agar and Hikton agar media. The
suspected colonies were subjected for staining and microscopically
examination. as well as to biochemical tests.
The aim of this study is to examine the role of oxidative stress (OS) by measuring Malondialdehye (MDA) levels to test Lipid Peroxidation as a marker of oxidative stress in serum samples in toxic injuries resulting from exposure to anticholinesterase
insecticides (organophosphates and carbamates) in greenhouse workers in the coastal region of Syria. The study population comprised two groups (the majority of males): greenhouse workers who prepare and spray pesticides (100 workers, aged 18-61) and Control group (not never handle pesticides, 50 subjects, aged 19-58). Malondialdehye (MDA) levels were measured using enzyme-linked immunosorbent assay (ELISA). There was a significant difference in MDA levels in greenhouse workers group compared to control group (P˂0.05). Therefore, MDA levels could be considered as a biomarker for oxidative stress in greenhouse workers exposed to anticholinesterase insecticides and might be a useful diagnostic aid and monitoring exposure in those workers as well as cholinesterase enzyme.
Carob pod is the fruit of the carob tree (Ceratonia siliqua L.). The
fruit and its products, sold both in large stores and local markets,
contribute strongly to the diet of people living in the Mediterranean areas
of Europe.
This study reports th
e composition of carob pods sampled in
Homs, Hama and Coast Regions
