Multidisciplinary team management is mandatory in order to estimate the optimal treatment regimen. GERMS.Introduction Co-infection has become a major contributor to increased burden of morbidity and mortality in HIV infection. The aim of this study was to assess the prevalence of asymptomatic malaria in the HIV-infected subjects on antimalarial prophylaxis and provide information to improve management of HIV subjects. Methods This was a cross-sectional study with a purposive sampling. Microscopy method was used for the confirmation of malaria parasitemia status. The study was performed in University of Calabar Teaching Hospital, Calabar, Cross River State, Nigeria, a major tertiary health institution within the period of January to June 2016 involving 100 participants. Results The majority (65%) of the study participants were females. The majority of the studied population belonged to the age range 33-38 years old. Most (45%) of the patients had CD4 count ≥500 cells/µL. The prevalence of asymptomatic malaria was found to be 13% (13/100). The distribution of asymptomatic malaria based on gender and age were found not to be statistically significant (P>0.05). Subjects with CD4 count in the range of 200-499 cells/µL had the highest prevalence (24.39%) of asymptomatic malaria. Conclusions Considering that all the studied participants were on antimalarial prophylaxis, it signals a public health concern to employ more intensive preventive methods in addition to antimalaria prophylaxis. GERMS.Introduction Medical students who engage in clinical learning in healthcare settings can be potential methicillin-resistant Staphylococcus aureus (MRSA) carriers. Methods This is a descriptive cross-sectional study having a follow-up approach. Three batches of medical students who were studying at the Faculty of Medicine and Allied Sciences, Rajarata University of Sri Lanka (1st, 3rd and 5th study years of MBBS course) were screened for nasal and axillary MRSA colonization. The first-year students were screened before and 6 months after clinical learning. The knowledge of the students about infection control was scored (percentage) using a questionnaire in the one week before and later one year after the hospital exposure. Data was compared using two-sample t test. Results The percentage of MRSA colonization was 6.36% (7/110) and 49.57% (59/119) before clinical exposure and after 2.5 years of exposure, respectively (p less then 0.012). The percentage of correct responses obtained by the students for the questionnaire about infection control was 28% and 66.9% one week before the exposure to the hospitals and one year after the exposure to the hospitals, consecutively. Conclusions MRSA carriage was significantly associated with the time duration of the clinical training of the medical students. The knowledge of students about infection control was significantly inadequate one week before the hospital exposure and they have gained the knowledge only after being exposed to the hospitals. GERMS.Introduction Gastroenteritis in children is responsible for high morbidity and mortality. Our aim was to determine the serum and fecal levels of interleukin-6 (IL-6) and interleukin-8 (IL-8) in children with acute gastroenteritis of viral and bacterial etiology to assess their utility as diagnostic biomarkers for these infections. Methods In this case-control study, the children were classified according to the pathogen recovered from the stool by bacterial culture or by direct viral antigen detection by enzyme immunoassay (EIA) into 50 children with acute bacterial gastroenteritis and 50 children with acute viral gastroenteritis. In addition, 50 apparently healthy children were included as a control group. Blood and stool samples were subjected to detection of IL-6 and IL-8. Results There were statistically significant elevations of total leucocytes counts, absolute neutrophils count, C-reactive protein, serum IL-6 and serum IL-8 in children with gastroenteritis compared to healthy children (p less then 0.001). CRP, serum IL-6 and IL-8 had significantly elevated levels in children with bacterial gastroenteritis compared to viral gastroenteritis. Fecal IL-6 and IL-8 had significantly elevated levels in children with acute gastroenteritis than in healthy control (p less then 0.001). The area under the curve (AUC) showed that CRP and serum IL-6 could be used as discriminative markers for acute bacterial gastroenteritis in children, in comparison to serum IL-8. Conclusions Elevated serum IL-6 and CRP can aid in differentiation between viral and bacterial gastroenteritis. Serum IL-8 had limited discrimination ability between viral and bacterial gastroenteritis. Stool levels of IL-6 and IL-8 were elevated in children with viral and bacterial gastroenteritis, however, their assessment by enzyme linked immunosorbent assay had technical limitations to be used as differentiation biomarkers. GERMS.Introduction Even though the increasing incidence of VIM-producing E. coli and K. pneumoniae has been reported worldwide, studies are still lacking in Palestine. The aim of this study was to screen carbapenem-resistant E. coli and K. pneumoniae bacteria in the Gaza Strip, Palestine and further to characterize carbapenemase-producing isolates. Methods A total of 69 E. coli and 27 K. pneumoniae isolates were obtained from three Gaza hospitals and recovered from urine, wound swabs, blood and ear discharge. The screening for metallo-β-lactamases (MBLs) was performed by using the imipenem-EDTA disc synergy test. The detection of β-lactamases genes, detection of non-β-lactam genes and the characterization of integrons were performed by PCR and sequencing. The clonal relationship among the isolates was determined by pulsed-field gel electrophoresis (PFGE). Results Our study showed that 4 E. coli (5.8%) and 5 K. pneumoniae (18.5%) were positive by the imipenem-EDTA disc synergy test. Bla VIM-4 was detected in six isolates and bla VIM-28 was identified in three isolates. The β-lactamases genes in the VIM-producing K. pneumoniae isolates were bla CTX-M-15 (n=3), bla CTX-M-14 (n=1), bla SHV-1 (n=3), bla SHV-12 (n=1), bla TEM-1 (n=1) and bla OXA-1 (n=1). Aac(6')-Ib-cr gene was confirmed in four E. coli and in two K. pneumoniae isolates. QnrS1 was identified in two K. pneumoniae isolates. selleck inhibitor The class 1 integron was identified with the different gene cassette; dfrA17-aadA5, dfrA5, dfrA12-orf-aadA2 and dfrA17-aadA5 were identified. Conclusions Our study indicated for the first time the emergence of multidrug-resistant VIM-containing K. pneumoniae and E. coli isolates of clinical origin in Gaza Strip hospitals. GERMS.
