A three-year descriptive study was done at Microbiology Laboratory, Ekiti State University Teaching Hospital, Ado Ekiti, from April 2012 to April 2015. Information compiled from patients’ records includes age, sex, isolated organisms and antibiotic susceptibility patterns. Three hundred and thirteen blood cultures were collected from neonatology and pediatrics wards, Out Patients’ Department (OPD) and from other adult patients. Forty one culture plates yielded mono microbial growth (no polymicrobial growth), giving an incidence of 13.1% positive blood culture (N = 41/313). There were 58.4% Gram negative bacilli and 41.6% Gram positive cocci in the microbial growth. Bacteria isolated were Staphylococcus aureus 34% (14/41), Klebsiella species 22% (9/41), Enterococci 17% (7/41), Proteus species 12% (5/41), Escherichia coli 7% (3/41) and Streptococcal pneumoniae 7% (3/41). There was a (35%) higher occurrence of septicemia in neonates than in any other age groups in the hospital. Bacterial sensitivity to 13 antibiotic agents was determined by antibiotics disc diffusion using modified Kirby Bauer’s method. Gram-positive organisms showed a higher antibiotic sensitivity ranging from 14% - 100% than the Gram-negative bacteria (11% - 80%). Staphylococcus aureus and Klebsiella species are the most prevalent organisms. The third generation Cephalosporins (Ceftriaxone) and Floroquinolone (Levofloxacin, Ofloxacin) have proved reliable for management of these blood infections.展开更多

We also aimed to determine the predictive strengths of both autoantibodies in the development of type-1 diabetes mellitus, and which of the two autoantibodies is a better predictive marker of type-1 diabetes mellitus among Nigerian adults. Methodology: A total number of four hundred and fifty five (455) subjects (211 (46%) males, and 244 (54%) females) aged between 35 - 76 years were recruited for the study. IAA and ICA levels were estimated using ELISA reagents from Biomerica Inc. Other parameters such as fasting blood sugar, urine glucose, and urine protein were assessed using standard biochemical techniques. Results: Relatives of type-1 diabetic patients and newly diagnosed type-1 diabetic patients were at greater risk (p < 0.05) of testing positive for more than one autoantibody (ICA and IAA) compared to non-diabetic controls. In addition, IAAs appeared to be better predictors or markers of type-1 diabetes mellitus compared to ICAs. Conclusion: The present study indicated a greater risk of autoim-mune destruction of the insulin producing beta cells of the pancrease of the type-1 relatives and newly diagnosed type-1 patients and suggests the need for periodic re-cruitment of individuals in the general population, siblings and relatives of type-1 diabetic patients for planned intervention trials. In addition, IAAs appeared to be better autoimmune markers of type-1 diabetes compared to ICAs.展开更多
