Summary— A study aimed at investigating the behavioural effects of aztreonam and gentamicin, given separately or in combination, was carried out in mice. Animals were randomly assigned to two test conditions: acute and chronic treatment. Those receiving acute treatment had a single IP injection 60 min before the test. Those receiving chronic treatment had IP injections once daily for 5 successive days prior to the test. Behavioural patterns (ambulation, rearing, grooming and defecation) were assessed using the “open‐field” test. The results indicate that, both after single and multiple dosing, aztreonam (10, 40 and 80 mg/kg IP) and/or gentamicin (10 mg/kg IP) do produce changes in the behaviour of animals. A rate increasing effect for certain behaviours (rearing, grooming and defecation) and a reduction in other behaviours (ambulation) seems to occur.
