The objective of this study is to investigate the resistance genes responsible for ESBL-producing Klebsiella species and carbapenemase-producing Klebsiella (CRE) isolated in Mthatha and to study their epidemiology. A prospective, descriptive study of 202 nonrepetitive samples from patients was obtained from Nelson Mandela Academic Hospital. The cultured Klebsiella isolates were subjected to antimicrobial susceptibility tests and the polymerase chain reaction of 𝑏𝑙𝑎CTX-M, 𝑏𝑙𝑎TEM, 𝑏𝑙𝑎SHV, 𝑏𝑙𝑎KPC, and 𝑏𝑙𝑎NDM genes. Overall K. pneumoniae were the majority with 169 (83.7%) species isolates, followed by K. oxytoca with 29 (14.4%), while K. ozaenae and Raoultella ornithinolytica were 2 (0.9%) each. The prevalence of ESBL production in all Klebsiella species was 117 (57.9%). ESBL-genotypic resistance is driven in Mthatha by 𝑏𝑙𝑎SHV 121 (77.1%) followed by 𝑏𝑙𝑎TEM 105 (66.9%) and 𝑏𝑙𝑎CTX-M at 89 (56.7%). The most common ESBL genotype combination among the Klebsiella was 𝑏𝑙𝑎TEM + 𝑏𝑙𝑎SHV + 𝑏𝑙𝑎CTX-M at 79 (50.3%). There is a steady increase in the rate of ESBL genes in the last five years. 2020-01-15T14:41:39Z 2020-01-15T14:41:39Z 2017-01 Journal https://new.hindawi.com/journals/ijmicro/2017/8486742/ https://ir.oauife.edu.ng/handle/123456789/5050 en application/pdf Hindawi Publishing Corporation |
