Streptococcus suis; a dominant specie found in pigs and environs, has been receiving drastic attention not only in causing human infections, but also for its involvement in antibiotic resistance, of which 80% of this resistant genes are encoded in the plasmid. This study was undertaken to evaluate the multiple antibiotic resistance indices of Streptococcus suis isolated from pigs and its environs A total of 430 samples were drawn from different sources (nasal swab, pork, pig droppings, pig feeds, bioaerosol), and screened for the presence of Streptococcus suis using standard microbiological techniques. The isolates obtained were characterized using their morphological, biochemical and molecular characteristics. The resistant strains were detected by subjecting the isolates to antibiotic susceptibility test using disk diffusion method.The study revealed the presence of Streptococcus suis strain SIO (SSS10), Streptococcus suis strain 347(SS347), Streptococcus suis strain 9401240 (SS9401240) and Streptococcus suis strain INT-10(SSINT-10), of which the isolates were significantly (α˂0.05) seen most in nasal swab samples. Of 24.14%, 100.00%, 41. 67% and 39.23% of SSS10, SS347, SS9401240 and SSINT-10 respectively that were resistant to antibiotics, 64.29%, 100.00% and 63.64% were multiple antibiotic resistant (MAR) strains, and 61.76% of the resistant strains had MAR index greater than 0.2. The study has shown SS10, SS347, SS9401240 and SSINT-10 were encountered from the pigs and its environs, and they exhibited significant degree of multiple antibiotic resistance, of which SS347 showed the highest percentage of MAR.
