Pathology, East Africa

Background: Staphylococcus aureus (S. aureus) has established itself over the years as a major cause of morbidity and mortality both within the community and in healthcare settings. Methicillin resistant S. aureus (MRSA) in particular has been a major cause of nosocomial infections resulting in significant increase in healthcare costs. In Africa, the MRSA prevalence has been shown to vary across different countries. In order to better understand the epidemiology of MRSA in a setting, it is important to define its population structure using molecular tools as different clones have been found to predominate in certain geographical locations.

Methods: We carried …

Spectrum Of Microbial Diseases And Resistance Patterns At A Private Teaching Hospital In Kenya: Implications For Clinical Practice, Daniel Maina, Geoffrey Omuse, Gunturu Revathi, Rodney Adam

Pathology, East Africa

Background: Accurate local prevalence of microbial diseases and microbial resistance data are vital for optimal treatment of patients. However, there are few reports of these data from developing countries, especially from sub-Saharan Africa. The status of Aga Khan University Hospital Nairobi as an internationally accredited hospital and a laboratory with an electronic medical record system has made it possible to analyze local prevalence and antimicrobial susceptibility data and compare it with other published data.

Methods: We have analyzed the spectrum of microbial agents and resistance patterns seen at a 300 bed tertiary private teaching hospital in Kenya using microbial identity …

Results From The Survey Of Antibiotic Resistance (Soar) 2011-14 In The Democratic Republic Of Congo, Ivory Coast, Republic Of Senegal And Kenya, A. Kacou-Ndouba, Gunturu Revathi, P. Mwathi, A. Seck, A. Diop, M. J. Kabedi-Bajani, W. Mwiti, M. J. Anguibi-Pokou, I. Morrissey, D. Torumkuney

Objectives: To assess antibiotic susceptibility of community-acquired respiratory tract isolates from Ivory Coast, Kenya, Democratic Republic of Congo (DRC) and Senegal in 2011–14.

Methods: Bacterial isolates were collected and MICs determined using Etest^® for all antibiotics except erythromycin, for which testing was by disc diffusion. Susceptibility was assessed using CLSI, EUCAST and pharmacokinetic/pharmacodynamic (PK/PD) breakpoints. For macrolide interpretation, CLSI breakpoints were adjusted for incubation in CO₂.

Results: Susceptibility to penicillin (using CLSI oral or EUCAST breakpoints) was low among isolates of Streptococcus pneumoniae from the DRC and Kenya (17.4% and 19%, respectively) but higher among isolates from …
