Introduction:Vertical Transmission of group B streptococcus (GBS) from a vagina colonized mother to her infant upon rupture of membranes (ROM) or after the onset of labor can cause life-threatening infections in newborn. Although intrapartum antibiotic prophylaxis (IAP) can significantly decrease neonatal GBS diseases, this issue has potentiated the emergence of antibiotic resistance strains. Our study examined the colonization rate of GBS using real-time PCR and culture methods, and trends in antibiotic resistance of GBS isolates obtained from pregnant women in Khorramabad, Iran.Methods:In this cross-sectional study, two vaginal-rectal swabs were collected and analyzed separately from 100 pregnant women at 35-37 weeks of gestation by convenience sampling method. The specimens were subjected to GBS detection using real-time PCR assay and standard culture. Susceptibility pattern of the GBS isolates was examined using the disk diffusion method.Results:GBS carriage rate was 17% and 19% using culture and real-time PCR, respectively. In six samples, the culture was positive and the real-time PCR was negative. Sensitivity and specificity for real-time PCR were 72.7% and 96.1%, respectively using culture as the gold standard. Amongst twenty-two isolates examined, 100% resistance to erythromycin and clindamycin was observed. One isolate (4%) exhibited resistance to penicillin.Conclusion:Considering the relatively high GBS carriage rate in Khorramabad, routine antepartum screening for GBS is recommended. Penicillin can remain the antibiotic of choice for IAP; however, in penicillin-allergic mothers, vancomycin can be an alternative antibiotic.
Aim:To determine the use of most popular forms of complementary and alternative medicine(CAM), sociodemographic characteristics of CAM users, and communication between CAM users and their physicians by adult Iranian in Khorramabad city.Methods:This cross-sectional study was carried out on clients who were at least 15 years in age referring to health centers and hospitals in Khorramabad town in 2014. A multi-part questionnaire was used to gather information. The demographic data and details regarding usage (number of times and underlying reasons) of different kinds of complementary and traditional medicine in the past were gathered using a questionnaire.Results:In this study 790 subjects were surveyed using the questionnaire. The mean age of the participant was 38.9 years. 79.8% of the subjects had used at least one of the methods of complementary medicine. Among the participants, 58.2% had used at least one of the complementary medicines in the previous year. Herbal medicine and prayers treatment had the highest use with 69.2% and 37.2%, respectively. Concerns of the side effects of medical therapy, beliefs in less risky being and fewer side effects of complementary medicine, Dissatisfaction of General Practitioners, the increase of being-well feelings in physical conditions, and were among the most important reasons of inclination towards such treatment methods.Conclusion:The analysis of using complementary medicine among people is the first step for planning proper use of the beneficial methods of complementary medicine and the prevention of inefficient and harmful methods in this respect.
Fasciola spp. and Dicrocoelium dendriticum as liver flukes, contaminate ruminants and other mammalian extensively and cause major diseases of livestock that create considerable economic losses. This retrospective study has been done to evaluate contamination rate of slaughtered animals with fasciolosis and dicrocoeliosis at Lorestan abattoirs. In this survey, prevalence rate of fasciolosis and dicrocoeliosis in slaughtered animals in a 3-year period (2010-2013) has been analyzed. A total of 356,605 livestock including 265,692 sheep and 90,913 goats were slaughtered in the 3-year period and overall 39,613 (11.1 %) livers were condemned. Fascioliasis and dicrocoeliosis were responsible for 6.3 and 4.8 % of total liver condemnations in this period, respectively. Fasciola spp. and D. dendriticum infection in sheep (7.1 and 5.6 %, respectively) were considerably higher than goats (3.9 and 2.6 %, respectively). The annual prevalence rates showed a significant decline in the fasciolosis and dicrocoeliosis infection in goats (p \ 0.001). Data showed significant seasonal pattern for distomatosis in sheep and goats (p \ 0.001). Liver condemnations due to fasciolosis were prevalent in sheep and goats slaughtered during spring and autumn, respectively, whereas dicrocoeliosis were common in spring season for both sheep and goats. This survey provides baseline data for the future monitoring of these potentially important parasitic infections in the region.
BackgroundEpidemiological data on antibiotic susceptibility of Staphylococcus strains isolated from nasal carriers in each region can be helpful to select appropriate drugs to eradicate carriage states, control nosocomial infections and also treat patients.ObjectivesThe current study aimed to investigate the antibiotic resistance profile and the molecular prevalence of the ermA, ermB, ermC and msrA genes among Staphylococcus strains isolated from the anterior nares of hospital employees.Patients and MethodsIn this cross-sectional study, a total of 100 Staphylococcus isolates, 51 Staphylococcus aureus, 49 coagulase-negative staphylococci (CoNS) were isolated from the anterior nares of hospital employees in Khorramabad, Iran. Susceptibility pattern to macrolide antibiotics were determined using the disk diffusion method. The polymerase chain reaction (PCR) assay was applied to determine the major erythromycin-resistant genes (ermA, ermB, ermC and msrA).ResultsFifty-three (53%) isolates were simultaneously resistant to erythromycin, azithromycin and clarithromycin (cross-resistance); while 8 (8%) isolates had variable macrolide susceptibility pattern. Among the S. aureus isolates, the difference in prevalence of resistance to erythromycin between males and females was significant (P = 0.011). The frequency of ermA, ermB, ermC, and msrA genes were 3%, 5%, 33% and 20%, respectively. It was also found that out of 53 isolates resistant to erythromycin, 44 (83%) isolates (eight S. aureus and thirty-six CoNS strains) carried at least one of the four tested genes. Eight (8%) isolates had intermediate phenotype to erythromycin, in which 4 (50%) isolates carried ermB or ermC genes. In addition, out of 39 erythromycin-susceptible isolates, 3 (7.7%) isolates were positive for ermB or ermC genes.ConclusionsNo entire association was found between genotype and phenotype methods to detect macrolides-resistant isolates. In addition, distribution of genetically erythromycin-resistant isolates is geographically different among staphylococci. It is recommend removing S. aureus from nasal carriers by proved approaches such as local or systemic administration of effective antibiotics or bacterial interference.
