Aim: This study investigated the occurrence of extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli in chickens from small-scale (backyard) commercial poultry farms in Maiduguri.
Materials and Methods: A total of 96 cloacal swab samples were collected. This comprised of 24 samples each from broiler chicks, pullets, layers, and broilers (adults). The samples were examined for the presence of E. coli using conventional microbiological culture and biochemical tests. The pure E. coli isolates were screened for ESBL production by culturing onto Brilliance™ ESBL agar. Isolates that showed positive reactions with production of bluish or pinkish colonies were tested for susceptibilities against some selected beta-lactam antibiotics which include cefotaxime (30 μg), ceftriaxone (30 μg), cefpodoxime (10 μg), aztreonam (30 μg), and ceftazidime (30 μg). Isolates that exhibited resistance to any two or three of the antibiotics were selected and confirmed by combination disk diffusion method with ceftazidime (30 μg) and cefotaxime (30 μg) alone and in combination with clavulanic acid (30 μg/10 μg).
Results: The total occurrence of E. coli was 67.6% (65/96) with the highest occurrence of 83.3% (20/24) from broiler chicks and least detection of 54.2% (13/24) from layers. Of this, 32.0% were ESBL-producing E. coli with the highest detection rate from layers (38.5%) and least occurrence from pullets (26.7%).
Conclusion: This study revealed the presence of ESBL-producing E. coli in chickens from small-scale commercial poultry farms in Maiduguri, thus indicating that chickens may serve as important reservoirs for the transmission of antimicrobial resistant pathogens to humans through the food chain.

Antimicrobial resistance has gained global notoriety due to its public health concern, the emergence of multiple drugresistant bacteria, and lack of new antimicrobials. Extended-spectrum beta-lactamase (ESBL)/ampicillin Class C (AmpC)- producing Escherichia coli and other zoonotic pathogens can be transmitted to humans from animals either through the food chain, direct contact or contamination of shared environments. There is a surge in the rate of resistance to medically important antibiotics such as carbapenem, ESBL, aminoglycosides, and fluoroquinolones among bacteria of zoonotic importance. Factors that may facilitate the occurrence, persistence and dissemination of ESBL/AmpC-Producing E. coli in humans and animal includes; 1). o ral administration of antimicrobials to humans primarily (by physician and health care providers) and secondarily to animals, 2). importation of parent stock and day-old chickens, 3). farm management practice and lack of water acidification in poultry, 4). contamination of feed, water and environment, 5). contamination of plants with feces of animals. Understanding these key factors will help reduce the level of resistance, thereby boosting the therapeutic effectiveness of antimicrobial agents in the treatment of animal and human infections. This review highlights the occurrence, risk factors, and public health importance of ESBL/AmpC-beta-lactamase producing E. coli isolated from livestock.Keywords
