Abstract:
تضمنت الدراسة الحالية تسليط الضوءعلى انتشار داء اللشمانيا الجلدية والاحشائية المتسبب من قبل الطفيلي Leishmania spp في مناطق مختلفة في محافظة ديالى ودراسة الظروف البيئية المساهمة في انتشار المرض ومقارنة الفحوصات السريرية والمختبرية والمصلية المستخدمة في تش | The aims of present study to illuminate a light on visceral and cutaneous leishminiasis disease caused by leishminia Spp parasite as registered in Diyal Governorate, and study the environment condition which contributed in diffusion the disease and comparison the tests of clinical, Laboratory and serological tests which used in diagnosing with PCR technique test, the study included many steps. 1. The epidemiologically which is main to determine the rates of infection as registered in some district of Diyala province in according to the age, sex, and the month of the year so according to the environmental conditions : - 7200 samples of blood collected from many different ages persons from different districts in Diyala. (3009 males, 4011 females) are examined. The study shows a positive cases of 607 distributed among the districts including (Jalawlaa, Bani Saa'd, Baladruz, Baquba, Alodeim amd DeliAbbas) these register a highest percentage of infection in Jalawlaa sub - district about 12.8% and less percentage of infection are in Baquba about 1.3% whiel is register highest percentage of in infection were (>1 - 5) years about 13.2% and lower percentage infection (<5 - 10) years wuth rate 2.4% so the groups of ages (25 - 30) years didn't appear any infections. according to the gender the males are high from the females whom effected with this disease the number of males (432) case with rate 71, 1%. The number of infected females about 175 cases with rate 28.8%.while in the month of years were the male infection are a highest infection in January - 2012, but did not register any infection in (June and July). The environmental condition infective in prevalence the disease between the people whom resident the houses which breed the animals inside, the number of infections are 245 cases from 607 positive cases with rate 40.3%. This was the low rate 4.9% from the infected people because of rats in their hoses. which didn't kill them. 2. The comparison of diagnostic methods of clinical test, laboratory test and serological test, with the molecular methods from the direction of sensitivity and specificity, The studies results appeared the importance of clinical test subtle in case of a similar cases depend on the clinical symptoms there are a highest cases from clinical test that the children suffering from liver magle their number are 176 cases the rate 80.36%, but the lowest cases of clinical test are 59.19% whom suffered from a skin pallor and black. The laboratory tests appeared the blood picture through testing the 350cases whom suspicion in their infection with leishmaniasis, the number of whom suffering from the lower of WBC 73 with rate 34.2%, while the low cases are 6 with rate 2.82% from whom suffering from hipper ESR, but the serological test was IFAT, Dipsrtick, spotkala - azor, ELISA, KA tex LATEX. Diagnostic infection leishmaniasis a best in diagnostic disease is dipstick test it's sensitivity are 95%, but it's specificity 100% but the lowest is the test of LATEX, it's sensitivity 75% and specificity 80%.3. The Molecular methods : PCR technique test clear recently the new highest sensitivity in diagnosis when the number of the parasite are a little in the blood in the infections peoples whom choose in random way. when testing 100 samples of DNA from the infection with cutaneous and visceral leishmaniasis, the number of infected male are 73, But the number of infected females are 27 with leishmaniasis. and studying the relation between PCR diagnosis according to the sex, age, district and environment condition, so as the recognize between the species of the parasite from the sequence Nitrogen basics with number in each species, (the species are L.donovani, L.infantum, L.tropica, L.major) so recognize the vector insect sand fly Morphology by key classification (ph.alexandri, ph.papatasi Ph.sergentasi, and sqauanlpleuris).
