Abstract: OLAES, LEANNE MARIE ESTU.O, Cavite State University, Indang, Cavite. Apri\ 2017. Prevaienee and Antimicrobiai Resistance Pattern of Escherichia coli Isolates in Fecal Samples of Layers from Selected Farms in Indang, CaviteUndergraduate Thesis, Doctor of Veterinary Medicine- Adviser: Chester Joshua V Saldana, DVM, MS. A study v,as conducted to determine the prevalence and antimicrobial sensitivity of Escherichia coli isolated from two hundred fifty three fecal samples of layeas from selected farms in Indang, Cavite- The antibiotic resistance pattems using disk diffusion method was also studied. It also includes the probable risk factors associated with development of antibiotic resistance- Results revealed that the overall prevalence or Escherichia coli in Indang, Cavite is 37.94% Samples from Carasuchi have the highest prevalence of 65% followed by Guyam Malaki (22.08%) and Daine Il ( 18.18%)- Further testing of isolates revealed that among the number of antibiotics tested, resistance was observed against bacitracin (100%) and erythromycin (100%). Isolates also showed resistance to ampicillin (85.41%), vancomycin (80.21%), tetracycline (70.83%), sulfamethoxazole (61.46%), lincomycin (57.29%), trimethoprim-sulfamethoxazole (53.13), and cephalexin (48.9696)On the other hand, isolates were found to be susceptible chloramphenicol (95.83%), gentamicin (86.46%), nitrofumntoin (70R3) and enronoxacin (56.25%)- Sixty different antimicrobial resistance patlems were observed in the study. Overall, the most frequent pattern recorded in three farms is TET-VAN-LIN-CEP-AMPERY-BAC- In Carasuchi, TET-VAN-LIN-CEP-AMP-ERY-BAC the most common pattern; NIT-VAN-CEP-TMPS-AMP-SUL-ERY-BACTET-VAN-LIN-ENR-ERY-BAC, VAN-LIN-TNåPS-AMP-SUL-ERY-BAC, and TET-VAN-LIN-TMPS-SUL-ERY-BAC in Daine Il and Guyam Malaki, respectively- Moreover, the resistance pattern varies per location with resistance phenotype were those having resistance in six to eigth (hexahepta and octa) antibioticsfrom Carasuchi with 21.54%, eight (octa) in Daine Il (50%) and six (hexa) in Guyam Malaki with 47.06% occurrence- Among the risk factors, the potential risk significantly associated with antibiotic resistance in E- coli was the administration of additional medicines- This study revealed the prevalence of multidrug resistant E coli isolates from layers in Indang, Cavite-
