Polymerase Chain Reaction (PCR) Assay for Rapid Diagnosis and Its Role in Prevention of Human Brucellosis in Punjab, India

Objectives: Brucellosis is the most common zoonotic disease that has been diagnosed mainly by serological tests and blood culture to some extent. This study was designed to establish a PCR technique for rapid diagnosis to be used in surveillance activities. Methods: The purpose of this study was firstly explained to the study population and verbal consent was obtained before sample collection. Peripheral blood was collected from 116 occupationally exposed groups with and without pyrexia of unknown origin from various districts of Punjab. Samples were subjected to blood culture, serological tests and DNA extraction was done using conventional laboratory extraction procedure. A primer pair B4/B5 that amplifies a gene encoding a 31 kDa immunogenic outer membrane protein (bcsp31) of Brucella species was used for PCR amplification. Results: The results showed that 8 (7%) of the cases had positive PCR and the detection threshold of primers used in this study were 715 cfu/ml. PCR results were 51.3% accurate for sensitivity of 12.6% and specificity of 100% using STAT as gold standard. Conclusions: Early-case reporting is possible by rapid tests like PCR. Thus, PCR is a promising diagnostic tool for routine investigation and surveillance of brucellosis which is the key element for management of prevention and control programmes. But patient condition before testing, optimal clinical specimen, sample volume used, simple and efficient DNA extraction protocol are the points of concern for PCR to be used as a routine test in clinical laboratory practice

Concomitant use of medicinal plants and pharmaceutical drugs among pregnant women in southern Ethiopia

Background: In several African nations, including Ethiopia, improving mother and child health is a top public health concern. Unfortunately, there is a dearth of study on pregnant women in Ethiopia who concomitantly utilize pharmaceutical drugs and medicinal plants. Hence, the objective of this research was to assess the concomitant use of pharmaceutical drugs and medicinal plants among pregnant women in Southern Ethiopia in 2021. Methods: A community-based cross-sectional study was conducted among systematically selected 400 pregnant women in Shashamane town, Southern Ethiopia, from July 1–30/2021. An interviewer-administered structured questionnaire was used to collect data. Binary logistic regression was performed to examine the association between a dependent variable and independent variables. Results: According to this study, among those who self-medicated, 90 (22.5%) reported using at least one pharmaceutical drug, while 180 (45%) reported using at least one medicinal plant. Moreover, 68 (17%) of the participants who had taken drugs while pregnant also used pharmaceutical drugs and medicinal plants concomitantly. Having a medical condition during pregnancy (AOR = 5.6, 95% CI: 2.7–11.6), not having ANC follow up (AOR = 2.9, 95% CI: 1.3–6.2), gestational age (AOR = 4.2, 95% CI: 1.6–10.7), and not having a formal education (AOR = 4.2, 95% CI: 1.3–13.4) were all significantly associated with concomitant use of pharmaceutical drugs and medicinal plants during pregnancy. Conclusion: This study showed that nearly one in five pregnant women used medicinal plants concomitantly with pharmaceutical drugs. Mother's educational status, medical illness during pregnancy, having ANC follow up and gestational period were significantly associated with concomitant use of medicinal plants and pharmaceutical drugs. Therefore, health care providers and concerned stakeholders should consider these factors to minimize the risks associated with drug use during pregnancy on both mother and fetus
