| Background: Staphylococcus species develop resistance to various antibiotics through different mechanisms, making them difficult to treat with standard therapies. Therefore, using alternative strategies to treat Staphylococcus species is urgent such as utilizing certain plant extract that may be promising branch in microbial therapy. Methods: Eucalyptus rostrata was collected from the farm around Al-Shomali hospital, Iraq in March 2023 and was kindly identified by botany expert. The leaves were air-dried and a weight of 10 g was used for liquid extraction. Gram positive bacteria Staphylococcus species were isolated from Iraqi patients from different body sites. The antibiotic susceptibility test was done by the standard disk diffusion method on Mueller-Hinton agar (MHA) as well as agar diffusion method. Results: The total of 60 staphylococcus species isolated clinically from different body sites divided to 30 S. aureus and 30 coagulase negative staph species (CoNS). Eucalyptus extracts (10g per 100 ml) gave 65% sensitivity for all isolates. The activity of eucalyptus is more than amoxicillin, ciprofloxacin, and ceftriaxone (P< 0.001). The activity of eucalyptus is equal in activity to both amikacin, and ciprofloxacin (P> 0.05). There are no significant differences between the sensitivity of eucalyptus in S. aureus 21(70%) and coagulase negative staph 18(60%) (P= 0.58). Conclusions: Eucalyptus rostrata extracts gave 65% sensitivity far all isolates. Its activity is more than amoxicillin, ciprofloxacin, and ceftriaxone (P< 0.001). The activity of eucalyptus is equal to both amikacin, and ciprofloxacin (P> 0.05). | ||||
