BackgroundVaginal colonization with group B Streptococcus (GBS) is the predominant risk factor for the development of invasive neonatal GBS diseases and puts newborns at increased risk for morbidity and mortality. This study is aimed to determine the colonization rate and antimicrobial susceptibility pattern of group B Streptococcus among pregnant women.MethodsHospital based cross-sectional study was conducted from August to December 2014 at selected health facilities. A total of 139 antenatal clinics attendees, proportionally allocated, were recruited consecutively. Socio-demographic and clinical factors were collected using a structured questionnaire. Vaginal swabs were collected and cultured on Todd Hewitt broth and in 5 % sheep blood agar. Antimicrobial susceptibility test was done using Kirby-Bauer disk diffusion test. Statistical analysis was performed using Pearson’s Chi square test.ResultsAmong the 139, 19 (13.7 %) were positive for GBS. All the GBS isolates were susceptible (100 %) to penicillin G, vancomycin, ampicillin, erythromycin and gentamicin. Two of the GBS isolates showed multidrug resistance against norfloxacin and ciprofloxacin. No statistically significant difference was observed for GBS colonization with any independent variables.ConclusionVaginal colonization of GBS for the present study put emphasis on further investigation and accomplishment of routine GBS screening practices. The recovery of resistant strains to antimicrobial agents recommended in cases of penicillin allergic mothers indicates the importance of susceptibility test.

Hepatitis B virus infection is one of the leading causes of liver disease in the world. This study was conducted to determine the prevalence of HBV infection and associated risk factors among pregnant women in Northern Ethiopia using a cross-sectional study design. A total of 328 pregnant women were included in this study. Clinical and socio-demographic data of the pregnant women were collected using a structured questionnaire by nurses or midwives during their ANC visit. For the detection of HBsAg, 5 mL of venous blood was collected from the pregnant women; serum was separated in the health facilities from the whole blood and was transported to Tigray Public Health Research Institute for analysis using. The data were analyzed using SPSS software version 20.0. (IBM). Association of variables with HBV infection was determined with multivariate analysis and P < 0.05 was considered statistically significant. The mean age of the study participants was 25.45 ± 5.067. The overall prevalence rate of HBV infection among the pregnant women was 5.5%. A statistical association of HBV infection with risk factors was seen on participants, who were making unprotected sexual practices with multiple partners (AoR = 6.4, 95%CI, 2-21, P = 0.03), on those who had HBV-infected person in their family (AoR = 8, 95%CI, 1-58, P = 0.02), and on those who had undergone surgical procedures (AoR = 6.8, 95%CI, 1-32, P = 0.022).

Objective To determine bacterial contaminants and their antimicrobial susceptibility patterns from medical equipment and inanimate surfaces. Results Of 130 swabs, 115 (88.5%) swabs were culture positive, of which contaminated medical equipment and inanimate surfaces account 70 (83.3%) and 45 (97.8%), respectively. All the swabs collected from sphygmomanometer, bedside table, computer and computer standing tables were 100% contaminated with bacteria. From the culture-positive swabs, a total of 171 bacterial isolates were identified, out of which 117 (68.4%) and 54 (31.6%) isolates were gram-positive and gram-negative, respectively. Most isolates (82%) were resistant to ampicillin and 13%, 8.6%, and 14% was observed in ciprofloxacin, gentamicin, and tetracycline respectively. Multi-drug resistant was observed in Escherichia coli (72.7%) and Staphylococcus aureus (58.7%).

This study was conducted in Ayder comprehensive specialized Hospital, Mekelle, Northern Ethiopia, to determine the bacterial profiles and drug susceptibility pattern from body fluids. A total of 218 patients were investigated, of which 146 (67%) were males. The age of the study subjects ranged from 2 days to 80 years with 96(44%) in the age group of 15 years and above. The overall bacterial infection was 44 (20.2 %) of which gram positive bacteria were prevalent, 23 (52.3%) than gram negative bacteria 21 (47.7%). The predominantly isolated bacteria were S. pneumonia, followed by K.pneumoniae, S. aureus, and E coli. Multidrug resistance was observed in 12 (100%) of the isolated gram positive bacteria and in 6 (75%) of the isolated gram negative bacteria.
