The susceptibility pattern to other antibiotics is shown within the table. Table 5 shows the MIC values of tetracycline for the isolates with each of the 203 isolates categorized as resistant (MIC five g/ml); 13 isolates (six.four ) had MIC worth of eight g/ml, 20 (9.9 ) had MIC worth of 16 g/ml, 4 (2.0 ) MIC worth of 32 g/ml, four (two.0 ) had MIC worth of 64 g/ ml, 20 (9.9 ) had MIC worth of 128 g/ml, 114 (56.2 ) had MIC value of 256 g/ml, and 28 (13.eight ) had MIC worth of 256 g/ml. Of the 203 isolates analyzed by PCR, 43.8 (89 of 203) carry tetA gene, 32.0 (65 of 203) carry tetB gene, whilst 4.four (9 of 203) carry both genes.
