AMR in Zambia: Key Findings
 S. pneumoniae resistance rates to penicillin rose from 14.3% resistance in 1990s to
53-67 % in 2007.
 Infants are most likely to have S. pneumoniae identified from their blood and spinal
fluid .
 Co-trimoxazole resistance of S. pneumoniae is high (80-100%).
 Enteric infections that affected Zambian children were due to rotavirus and enteric
bacteria (E. coli, V. cholerae, Salmonella spp., and Shigella spp.).
 Available data showed very high resistance among enteric bacteria to gentamicin,
cefotaxime, nalidixic acid, ciprofloxacin, co-trimoxazole and cephalexin ranges
between 70-100%.

AMR in Uganda: Key Findings
 Acute respiratory and enteric infections in Uganda are main causes of
increased morbidity, mortality and costs.
 Streptococcus pneumoniae, and Haemophilus influenzae type b (Hib)
continue to be the main bacteria responsible for Acute Respiratory Infections
(ARI). Viral etiology (mainly Respiratory Syncytial Virus-RSV) in severe
pneumonia among infants and children needs to be investigated.
 Empirical treatment should be guided by data provided by antibiotic
resistance surveillance, particularly in common pathogens.
 Available information on Antibiotic Resistance (ABR) is in most cases
scattered, incomplete and often unreliable.

respectively.
Structured questionnaires (adapted from the WHO assessment
form) were used to conduct the interview.
Training of data collectors was carried out
The survey was carried out 2009 and 2010.
The study obtained ethical approvals from the University of
Zambia Ethical Review Board, the Ethical Review Committee of
Makerere University College of Health Sciences, Kampala, and
Boston Tufts University Institutional Review Board
