<t>Beta</t> lactam recovery from B. dubia roaches over time. Cefotaxime ( A ), carbenicillin ( B ), or ampicillin ( C ) was injected into B. dubia roaches at the dose indicated. At the designated time points, hemolymph was extracted and was mixed with an anticoagulant. This material was dispensed onto a disk of sterile filter paper which was placed onto TSA containing E. coli that had been spread-plated. Following incubation, zones of inhibition were measured; to estimate the amount of antibiotic recovered, the values for the zones of inhibition generated from the recovered hemolymph were compared to a standard curve.

Treatment with cefotaxime reduces bacterial burden in a dose dependent manner that is specific to the activity of this drug. B. dubia cockroaches were infected with a lethal dose of E. coli ( A ), K. pneumoniae (BLS, Beta-lactam sensitive strain) ( B ), or K. pneumoniae (BAA-2146, Beta-lactam resistant) ( C ). Alternatively, B. dubia cockroaches were infected with a sublethal dose of E. coli ( D ) or K. pneumoniae BLS ( E ). At 24 h post infection, surviving cockroaches were euthanized and their hemolymph was isolated and mixed with an anticoagulant. This material was serially diluted and plated to enumerate CFU. CFU recovered from hemolymph was compared to input. These data were analyzed by a one way ANOVA and Tukey’s post hoc ( A , P < 0.0001; P < 0.0001for 5 mg, 0.5 mg, 0.05 mg; P = 0.0784 for 0.005 mg cefotaxime.
