Spices are becoming increasingly important world-wide due to their effectiveness as natural antibiotics, the thing that makes the world nowadays tend to use spices instead of chemical drugs. However, this doesn’t mean they are free of some dangerous pathogens such as Klebsiella spp. which can lead to a wide range of illnesses, notably pneumonia, urinary tract infections (UTIs), and bacteremia. Although we don’t know the natural habitat of this bacterium we find that it thrives in herbs and spices, concluding thus that plants may be its natural habitat. The primary isolation of this bacterium was based first on its growth on general media and then isolation on selective media. Colonies of the microorganisms were counted on different media then Klebsiella was isolated from a selective media. The isolated colonies of Klebsiella were circular, dome-shaped, 3-4 mm in diameter, with mucoid sticky edges, and surrounded by capsule. After this we chose the typical colony and identified it using Polymerase chain reaction PCR and biochemical tests. Our results showed that 32% of examined specimen contained Klebsiella spp.
Economic losses resulting from the impact of brucellosis on animals have increased, which is reflected in turn on humans. Brucella is pathogenic bacteria shared by humans and pet animals. They still pose a significant risk that threatens health an d economics in Syria. Many efforts have focused to prevent the spread of brucellosis disease, by resorting to the use of vaccines prepared from Brucella strains, where now the target is preparation of vaccine components proteins of Brucella can be used as a vaccine or an improved traditional vaccine.
Thirteen viable and post - frozenthawed Shami cows embryos obtained by super-ovulation and artificial insemination technique in order to determine sex of embryos. Biopsies (1-2 cells) of embryos at morula or blastocyst stage were taken using micro manipulation under inverted microscope. It was concluded that aspiration of 1-2 blastomere (s) from embryos at morula or blastocyst stage was enough to determine sex of embryo using PCR and it is recommended that using this technique can be a useful tool in splitting and transferring of desired sex embryos in genetic improvement program.
This study aimed to investigate the possibility of rapid identification of isolated bacteria Leuconostoc from Syrian white fresh cheese made of cow and ewe milk using Fourier transform infrared spectroscopy (FTIR). 20 isolates (14 from ewe milk ch eese and 6 from cow milk cheese) were isolated. These isolates were pretasted with PCR technique using specific primers. Results indicated that these isolates are belonged to the genus Leuconostoc and 12 of them are belonged to Ln. mesenteroides species. The results of FTIR technique showed in comparison to device library that all isolates are belonged to genus Leuconostoc, and 4 of these isolates are belonged to Ln. citreum species which could not be identified using PCR method (with the used primers), and helped to identify the following subspecies: Ln.mesenteroides subsp mesenteroides and Ln. mesenteroides subsp dextranicum while PCR technique described them belonging only to a Ln. mesenteroides species. Moreover, FTIR technique was able to give the results within 25 hours, thus it can be used in identification of food bacteria more quickly.
This study was conducted in the years 2008-2009-2010, it has analyzed for Staph. aureus and isolated from 100 samples of traditional ice cream sold to customers it has had collected from different regions parts of Damascus and his countryside. The study has been found that there was no violation of the Syrian standard for Staph. aureus. And the results were also diagnosed using the techniques of API Staph and PCR equal.
This research was conducted at the Department of Food Science, Faculty of Agriculture and National commission for posterity energy. Twenty kg of apple juice concentrate (70%) were tooked from company of Natural Aljabal Juice from AL-suidaa Govern orate and prarerd two concentarate (15% and 35%) by using distilled –sterlization water according to pirson .
The aim of this research was detection Listeria in chopped prepared to consumption beef. (100) samples were collected randomly from Damascus and its countryside, Kenitra and Sweida stores and slaughterhouses, from February (2015) to February (2016).
Chronic periodontitis (CP) is an inflammatory disease, characterized by gingivitis, and affecting tooth supporting tissues, forming periodontal pockets with associated attachment loss, alveolar bone resorption. It is common in adults, but can also occur at any age. The rate of disease progression may be influenced by local, systemic conditions, and/or environmental factors that alter the normal host response to bacterial plaque, and affect the susceptibility to disease.It is suggested that periodontitis is partially associated by genetic factors, that many genes are involved in inflammation susceptibility, mainly include the vitamin D receptor (VDR) gene that is implicated in bone metabolism and the host immune response. 80 Syrian subjects were recruited for vitamin D receptor gene polymorphism study, and allocated in two groups: 50 diagnosed with CP and mean age was (64 ± 0.722) years, 30 matched controls. DNA was isolated from peripheral blood cells, and genotyping was performed by polymerase chain reaction (PCR) method and restriction fragment length polymorphism analysis (RFLP) by using FokI enzyme. By using Chi square test, no significant differences were found between the study groups in the frequencies of alleles and genotypes at FokI position of VDR gene, age and sex. These findings suggest that the investigated factors are not associated with periodontal disease in this studied sample of Syrian population.
