Abstract
Multidrug resistant (MDR) Pseudomonas
aeruginosa is a prominent bacterial pathogen conferring resistance to
variety of antimicrobial agents. The ability to form biofilms further enhances
the drug resistance phenomena of P.
aeruginosa. The emergence of biofilm forming MDR strains of P. aeruginosa
in meat and food products is a serious public health concern. In present study,
total 100 meat samples were collected (50 each from chicken and mutton) from
different butcher shops and supermarkets and P. aeruginosa was isolated
by standard microbiological, biochemical and molecular techniques. The
resistance profile against various antibiotics was detected by Kirby Bauer
method while the biofilm production was observed by microtiter plate assay. The
biofilm associated gene (pslA) and
extended spectrum beta lactamase (ESBL) genes were detected by polymerase chain
reaction (PCR). The study outcome revealed that
P. aeruginosa was isolated from 24% meat samples comprising
14/50 (28%) from chicken and 10/50
(20%) from mutton samples. The highest resistance (100%) was observed
against Amoxicillin-Clavulanic acid and Ceftriaxone followed by (95.83%) for Aztreonam, Ticracillin and
(91.67%) to ciprofloxacin. Out of 24
isolated P. aeruginosa,
22 (91.66%) were detected as MDR. Furthermore, among the 22 MDR isolates,
19 (86.36%) were found biofilm producing
P. aeruginosa and all of them detected positive for biofilm encoding gene (pslA). In addition, 9 (40.90%) MDR isolates showed presence of ESBL
genes including 6 blaCTX-M and
03 blaTEM while none of the isolates was found positive for blaNDM
and blaOXA genes. This study concludes that antibiotic resistance is more
pronounced in biofilm producing P. aeruginosa and presence of these
biofilm forming isolates in the food chain is a serious threat to public health.
