ABSTRACT
Background: Moraxella catarrhalis is gaining significance as a pathogen over few decades because of increased rate of isolation in respiratory specimens and due to emergence of multidrug resistant strains. Therefore, appropriate antimicrobial agents are required for eradication and prevention of spread of the organism. Material and Methods: -The study was conducted over 1-year period inpatients of lower respiratory tract infections (L.R.T.I.) in P.G.I.M.S. Rohtak (Haryana) . Assessment of clinical significance of M.catarrhalis was ascertained on the basis of preformed criteria. Results: A total of 63 clinically significant M. catarrhalis were isolated from a tertiary care hospital. The isolates showed maximum resistance to cotrimoxazole (82.5%), pencillin (77.7%), and ampicillin (71.4%) while susceptibility was maximum to cefotaxime (87.3%) followed by tetracycline (85.7%) ciprofloxacin (84.1%), erythromycin (80.9%) amikacin (79.3%), gentamycin (77.7%), and cefazolin (76.2%). Multidrug resistance to >3 antimicrobials was seen in 22 (34.9%) of cases. Conclusions: Predominant or pure growth of M.catarrhalis in throat swabs from cases of L.R.T.I. should be reported and treated by microbiologist and clinician respectively. Antibiotic therapy should be decided based on sensitivity report for rapid respose and recovery of patients.
ABSTRACT
AIMS: This study has analyzed the role of rubella and cytomegalovirus (CMV) in infections of children and pregnant women. SETTINGS AND DESIGN: The study was carried out in a tertiary care hospital. Data from blood samples from pregnant women (asymptomatic and also women with obstetric problems) and children (suspected of intrauterine infections) that were received in the laboratory over a period of 8 years were analysed. MATERIALS AND METHODS: The samples were tested for rubella- and CMV-specific IgM antibodies by capture enzyme linked immunosorbent assay. RESULTS: In children, the overall positivity for rubella- and CMV-specific IgM antibodies was 2.8% and 12.5%, respectively. In asymptomatic pregnant females, rubella positivity was 0.7% while in women with obstetric complications it was 3.4%. IgM antibody positivity in cases of CMV was 7.8% in both asymptomatic pregnant women and also in women with obstetric complications. CONCLUSIONS: The study indicated that infection with CMV is more common than the rubella virus. The incidence of rubella has reduced over the past few years. Hence, screening for rubella infection may be reserved for women with obstetric complications only. The routine screening for CMV among all antenatal cases is a debatable issue.
