Identification and antibiotic resistance patterns of Klebsiella sp. isolated from the feces of Bornean Orangutans (Pongo pygmaeus) at Taman Safari Indonesia, Bogor

Abstract

Orangutans are the only great apes that still survive in the Southeast Asian Region. However, their population in the wild habitat continues to decline, with estimates indicating a 50% decreased over the last 60 years. There is limited microbiological data on the antibiotic resistance of Klebsiella sp. in the feces of Bornean Orangutan (Pongo pygmaeus). This study aimed to identify the presence of Klebsiella sp. and assess its resistance pattern to various antibiotics in the feces of Bornean Orangutans. The research involved isolation, identification, and antibiotic resistance testing. Results showed that three isolates (37.5%) were positive for Klebsiella sp. Sensitivity test revealed two distinct resistance patterns among Klebsiella sp. isolates from the feces of healthy P. pygmaeus in Taman Safari Indonesia, Bogor. These isolates exhibited resistance to β-lactam antibiotics but remained sensitive to aminoglycoside, tetracycline, and fluoroquinolone antibiotics.
