Abstract:
الحمى المجهولة من الامراض الواسعة الانتشار في العالم تحدث بسبب جرثومة الكوكسيلا بيرنتي.هذه الجرثومة تسبب عدة امراض الاجهاض هو الاكثر حدوثا. المخاطر البيولوجية وانشار هذه البكتريا على النساء المجهضة والحيوانات في العراق غير معروفة. لذلك هدفت هذه الدراسة ال | Query fever is a worldwide distributed disease caused by Coxiella burnetii bacteria causes several disease main of this disease is abortion, the biological hazard and prevalence of this bacterium on the aborted woman and small ruminants are not known in Iraq. Therefore this study was aimed to detection and isolation of Coxiella burnetii as a causative agent of abortion in woman and female of small ruminants.352 samples were collected includes human samples and animals samples. A total of 120 blood aborted women, 7 breast milk samples, 20 placental samples and 50 blood samples from normal women as control groups, these samples collected from Bent Al - Huda hospital in Thi - Qar province. Animals samples, a total of 80 aborted animal blood samples, 15 milk samples, 10 placental samples and 50 blood samples, these samples from normal animals as controls group, these samples collected from veterinary hospital in Thi - Qar province. The results of this study showed a high incidence of abortion occurs in first trimester of gestation (41.666%) and high incidence in rural regions (64.16%) and also age group from 21 to 30 years old (50%).The methods used for detection of Coxiella burnetii includes serology tests, polymerase chain reaction (PCR) technique for confirmation serological test and isolation on embryonated chicken eggs and detection by PCR technique. Out of the 120 women serum samples analyzed by enzyme ELISA, the results of percentage of anti - Coxiella burnetii IgM and IgG in human samples were 36 (30 %). The percentage of anti - C. coxiella IgM in human samples were 10 (8.333%), while the percentage of anti - C. Coxiella burnetii IgG in human 26(%21.667%).. In animals total of (80) serum samples, the percentage of anti - C. coxiella IgM and IgG in animals' serum samples were 31(38.75%) The percentage of anti - Coxiella burnetii IgM in animals 10 (12.5%), while, the percentage of anti - C. coxiella IgG in animals are 21(26.25 %). PCR technique used for identification of Coxiella burnetii in human and animals samples by targeting three genes including outer membrane protein (com1 and com2), 16S rRNA and transposase insertion element (IS1111) genes. In human blood samples the com1 and com2 genes detected in 23of 120 (19.166%) samples and in breast milk samples 1 of 7 (14.28%). and not detected in placental samples. The 16S rRNA gene was detected in 16 of 120 blood samples (13.33%) and in breast milk samples and placental samples were not detected. The IS1111 gene was detected in 9 of 120 blood samples (7.5%) in human blood samples, also were not detected in milk and placental samples.. In animals blood samples the com1 and com2 genes were detected in 19 of 80 blood samples (23.75%) and were not detected in milk and placental samples. The 16S rRNA gene detected in the same percentage of com1 and com2 genes 19 of 80(23.75%) and in the milk samples and placental samples not detected. The IS1111 gene detected in 10 of 80 (12.5%) in animal blood samples, also were not detected in placental samples. An isolation of Coxiella burnetii which identified by ELISA and PCR via inoculated Coxiella burnetii buffy coat samples in embryonated chicken eggs from 6 to7 days old and then completed an incubated to 10 - 15 days, harvested yolk sac contains then detecting Coxiella burnetii by PCR. The results of PCR after inoculation of (43) samples were positive in PCR (100%). Statistical analysis revealed no significant different between ELISA test, PCR and isolation results in human and animals samples. These mean that we can use the ELISA in the primary diagnosis. The correlation coefficient was highly significantly between human and animal samples at 0.01%.
