While at student dormitory, it was shown that Enterobacter was resistant to ampicillin (84.6%) and
amoxicillin (61.5%). Klebsiella exhibited full resistance to amoxicillin and ampicillin at hospitals F and Q. Klebsiella was resistant to amoxicillin (60%) and ampicillin (100%) at dormitory. At hospital F and student dormitory, Acinetobacter demonstrated full resistance to amoxicillin,
ampicillin and cephalothin, while at hospital Q, it had full resistance to amoxicillin and ampicillin, but only 50% resistance to cephalothin was discerned. Enterococus was fully resistant to penicillin and vancomycin separately at hospital Q and only shown resistance to penicillin at dormitory (Table 2). The most resistant bacteria at hospital F isolated from German and American cockroaches were Pseudomonas and Acinetobacter which had drug resistance
to at least four antibiotics. Similarly, the most resistant bacteria at hospital Q isolated from these cockroaches were Pseudomonas (resistant to at least 7 antibiotics) as well as
Acinetobacter and Enterococcus was resistant to a lower number of antibiotics (Table 2).
