Abstract:
اجريت الدراسة الحالية في قسم علوم الحياة - كلية التربية للبنات - جامعة الكوفة للمدة من تموز 2011 ولغاية حزيران 2012 والتي تهدف الى دراسة وبائية طفيلي Giardia lamblia وتحديد الانماط الوراثية للطفيلي لدى المرضى المصابين بالاسهال في محافظة النجف الاشرف باستع | The Present study was carried out in the Department of Biology - College of Education for Girls - University of Kufa for the period from July 2011 until June 2012, it aims to study the prevalence of the Giardia lamblia parasite and identify genotypes of the parasite in patients with diarrhea in the province of Najaf by using the microscopic examination and the polymerase chain reaction (PCR).The results of microscopic examination of 3383 stool samples, 500 samples are infected by the G. lamblia parasite, with a total percentage of 14.8%. The results of the statistical analysis showed that there were significant differences at the level of probability P ? 0.05 where the rate of infection in the liquid samples was higher than it is in semi - liquid samples, reaching 17.2% and 10.7% respectively. As the results show the incidence of the parasite in males are higher than it in females reached 16.8% and 11.1%, respectively, as well as the spread of infection with the parasite in the rural areas more than the urban area where the ratio was 19.6% and 9.1%, respectively, the results also show that the highest infection rate with the parasite was in the age group aged (1ess than year) and the lowest in the group aged (36 - 40) years, reaching 28.0% and 10.0%, respectively. The results also show that the highest percentage of parasite infection was in the September, 44%, while the lowest infection rate was in December, reaching 6.1%. The results of the current study show that the highest infection rate parasite was in patients in the hospital of Manathira which amounted to 16.5% and that the lower infection rate was among patients of the Medical Al - Sader city hospital, reaching 11.7%. The results of extracting (100) Stool Samples by microscopic examination for patients infected with G.lamblia showed the presence of the gentic material DNA of the G. lamblia parasite in (41) samples which constitute 41%, and results of the examination by PCR by using Triose phosphate isomerase (Tpi) Showed that there are signiinficant differences at the level of probability, p ? 0.05 percentage infection with the genotype (B) compared with the genotype (A), which were 61% and 39.1% respectively.The highest rate of infection with the genotype (B) in the semi - liquid samples was 69.3% compared to the liquid samples, which amounted to 67.9%, while the genotype (A) had the highest rate of infection in the liquid samples, which amounted to 32.2% while it was 30.8% in the semi - liquid samples.As the results showed that the percentage of infected male with the genotype (B) was more than it is in females, reaching 62.5% and 58.9%, respectively, and in type (A) the infection of females was higher than the infection males 41.2% and 37.5% respectively. As the results show the spread of genotype (B) in the urban area is more than the rural area, the percentage of infection is, 72.8% and 66.7% respectively, while type (A) was more prevalent in rural than in the urban, where the percentage of infection is 33.4% and 27.3% respectively.The results also showed that the highest incidence of the genotype (B) was in the age group (41 - 45), it reached 75% and the lowest percentage in the age group(1 - 5) (11 - 15) (26 - 30) (36 - 40) years, amounting to 50%, while genotype (A), the highest rate of infection, when age group (1 - 5)(11 - 15)(26 - 30)(36 - 40) years to approximately 50% and the lowest percentage of infection in the age group (41 - 45), was 25%.
