[Screening study of changes which have occurred in the prevalence of intestinal parasites species in Syria between 2006-2011]

The aim of the study was to evaluate the changes which have occurred in the prevalence of intestinal parasites species in Syria between 2006-2011. This study was carried on in seven cities in Syria on primary school students in the years 2006-2011. The number of student's fecal samples examined was 4152 from seven Syrian areas included: Damascus and its countryside, Idlib and countryside, countryside of Daraa, Kalamoon, Hama and countryside, countryside of Alraqa and countryside of Tartous. The results showed that there were 1290 stool samples with positive parasites [31.07%], 481 samples of them have pathogenic human's parasites [37.28%]. The pathogenic parasites which have been seen in this study according to their prevalence rate were as follows: Protozoa: Giardia lamblia 8.48%, Chilomastix mesnili 1.06%, Entamoeba histolytica 0.14%. Helminthes: Hymenolepis nana 1.20%, Enterobius vermicularis 0.43%, Strongyloides stercoralis 0.17%, Trichuris trichuria 0.05%, and Ascaris 0.05%. Where the non pathogenic parasite which have been seen in this study according to their prevalence rate were as follows: Blastocystis hominis 13.15%, Entamoeba coli 5.73% and Iodamoeba butschili 0.60%. It was observed that Giardia lamblia and Hymenolepis nana which regarded as pathogenic parasites were the most prevalent in Syria, bt the other types of parasites were very rare

[Detection of Toxoplasmosis antibodies among Arab International University female students in Syria Screening study by direct agglutination latex]

There are no sufficient studies about the prevalence of Toxoplasmosis in Syrian females, so our aim in this paper were 1] Screening study of Toxoplasmosis antibodies among Arab International University female students in Syria, 2] determination of positive percentage to spread the disease, 3] set up a health educational program for prevention means of sero-negative cases. A total of [313] blood samples were collected from female students [age 19-23]. Blood was separated and serum was collected and kept in small labeled eppendorf tubes and stored at -20 degree C until analyzed. A direct agglutination test was used for detection of Toxoplasma antibodies. [Kits from human Ref 50023]. The positive prevalence of Toxoplasmosis antibodies was 47% among female students, while 53% was negative. A health educational program was set up for sero-negative students to explain the risk of this disease. Toxoplasmosis is still making a high pathogenic risk factor in Syria. Food, weather and environment help to spread of this parasite, and infection increases with aging

[Diagnosis and treatment of demodectic belpharitis, the first case in Syria]

Demodex is an acarina parasite belongs to family of Tromidiformes, It is worm-like, with a length of 100-400 micron. There are many kind of Demodex affect on animals, and just two types infect humans and they are: Demodex folliculorum and Demodex brives. This mite, living in the hair follicle, in sebaceous gland of human, on the face, nose, neck and lids. Its complete the whole lifecycle, which is approximately 15 days in hair follicle and it spreads via direct contact. Many researches have shown that Demodex is involved in many kinds of dermatitis especially acne rosacea, and a lot of cases have been diagnosed in our country, that were published in scientific journals. Recently, it has been reported that Demodex mites play an active role in the pathogenesis of Blepharitis. It has been suggested that this parasite cause acne, pityriasis folliculorum, papullo-pustular rosacea, granulomatous rosacea, inflammatory papule and folliculitis. This study is about a female case in twenty year old, explained of a huge dropping of her eyelashes, thick squamous in the base of eyelashes and oedema in the edge of the lids. The case was treated with metronidazole ointment and it is recovered within two months

Prevalence of intestinal parasites in children of elementary educational level in rural of daraa Governorate- Syria

Is to know the prevalence of intestinal parasites among children in elementary educational level in rural ofDaraa - Syria. A total of 766 stool samples were examined, they were collected from children in elementary educational level from 62 villages in rural ofDaraa in the period from July to October, 2009. Of 261 [34.7%] samples positive for parasites, 160 samples of them contained human pathogenic parasites. The pathogenic parasites according to their prevalence were: Giardia lambilia [12.66%], Candida sp. [5.74%], Chilomastix mesnili [1.96%], Hymenolepis nana [1.94%], Strongyloides stercoralis [0.9%] and finally Enterobius vermicularis [0.39%]. Strongyloides stercoralis was detected for the first time in this area. The prevalence of nonpathogenic parasites was: Entamoeba coll [9.4%], Blastocystis hominis [8.62%], Enteromonas intestinalis [0.65%], and Endolimax nana [0.39%]. It is worth mentioning thatAscaris lumbricoides and Entamoeba histolytica were not detected in any of the study samples. Giardia lamblia is the most common pathogenic protozoa in rural area of Daraa in Syria; while Hymenolepis nana is the most common intestinal helminthes in this area followed by Enterobius vermicularis then Strongyloides stercoralis
