Abstract:
اجريت هذه الدراسة التي امتدت من بداية شهر ايار (2007) لغاية نهاية شهر اب (2008) للتحري عن نسبة الخمج بالطفيلي المسبب لداء المقوسات بين النساء المجهضات والولودات طبيعا في بعض مناطق مدينة الموصل والمراجعات لمستشفى الخنساء التعليمي للولادة والاطفال.شملت عي | This study was conducted during the period from May 2007 to August 2008 to investigate the rate of infection with toxoplasmosis among aborted and normally delivered women in Mosul City territories who attending AL - Khansa'a educating hospital.Out of 150 women under study, 50 were aborted while 100 were normally delivered. The employed tests were included latex agglutination test LATEX and Enzyme Linked Immunosorbent Assay (ELISA) with its two types (ELISA - IgM), (ELISA - IgG) which used as a high specific and sensitive test to differentiate between types of infection acute, chronic and congenital. Toxoplasmosis was diagnosed in 28(56%) out of 50 abortive placenta and in 57(57%) out of 100 non abortive placenta (normally delivered women), these samples of placenta were microscopically examined after homogenizing and staining by Gimsa and Leishman's stain The parasite development stages were also noticed including developing from the tachyzoites into the oocysts stage and the histopathological effects resulting from infection in the placenta in both aborted and normally delivered women which were represented by necrosis, vaculation and cells degeneration , inflammatory cells infiltration and the focal inflammatory reaction in the villi in addition to hemorrhage and accumulation of eosinophilic substances, the results also showed that 41 (82%) of aborted placenta and 18 (18%) of non abortive placenta (normal delivered women) were infected with Toxoplasmosis by using the laboratory Balb/c mice inoculation method while, some cases of inflammation were diagnosed in the brain, of the experimental infected mice, which were represented by the inflammatory cells infiltration and the prevailing of gliosis, tissue necrosis vaculation and cells degeneration.This study revealed that laboratory mice inoculation in the peritoneal cavity is a useful and efficient method in the detection of the parasite in infected placenta as compared with the microscopic examination of direct smears and examination of tissue sections from placenta.The present study showed an overall percentage of infection among aborted women was (92%) while (58%) showed an acute infection and (34%) chronic infection, in another hand the infection rate among normally delivered women was (70%), and it has been found the infection rate among acute and chronic cases were (41%), (20%) respectively, Its to be noted this is the first time in Mosul City for such a study conducted in this area concerning the congenital Toxoplasmosis in newborns with an infection rate (9%).In this study, sera were tested by Latex (LAT), and Enzyme Linked Immunosorbent Assay (ELISA). It was shown that IgG - ELISA is the most sensitive to diagnose the infection as compared to other tests.These study also concerned with the isolation and diagnosis of Toxoplasma gondii parasite from blood by inoculating the blood samples in laboratory Balb/C mice the rate of infection was (16%) in laboratory mice inoculated with blood collected from aborted women while the infection rate in laboratory mice inoculated by blood samples (mother and her neonatal cord blood) collected from normally delivered women appear in (12%) & (16%) respectively. The rate of occurrence of the specific antibodies against Toxoplasma gondii was identified, The highest rate was found for the type (IgG+ - IgM+), in both aborted and normally delivered women with percentage reach (40%) & (26%). The titer (100 IU/ml) of the specific IgM & IgG antibodies was found in high rate reached (75%), (43.5%) in mother blood, also found in a high percentage in the neonatal cord blood estimated as (50%), (64.4%) for the specific IgM & IgG antibodies respectively, in another hand the titer (100 IU/ml) was also found to be the more predominate titer in blood samples of aborted women with percentage reached to (50%) & (60.5%) for the specific IgM & IgG antibodies respectively.
