Pollution is a global concern, increasing rapidly throughout marine and terrestrial ecosystems, and affecting many species. Urbanization enhances waste production, leading to the opening of landfills that constitute a spatially and temporally predictable food source for opportunistic species. Several species of gulls are known to exploit and breed in urban areas, taking advantage of accessible and diverse food resources.

Article Synopsis
  • Metal pollution in marine ecosystems is significantly affecting seabirds, with a study measuring 13 metals in two gull species from different colonies.
  • Audouin's gull showed higher contamination levels due to its primary diet of fish, while Yellow-legged gulls have lower levels because of their diverse diet that includes terrestrial foods.
  • The study found that oxidative stress in the birds was more linked to their foraging habits and ecology rather than the levels of metal contamination itself.

Objectives: To analyze the susceptibility of Neisseria gonorrhoeae isolates to penicillin (Pen), cefixime (Cfm), ceftriaxone (Cro), tetracycline (Tet), ciprofloxacin (Cip), azithromycin (Azm), and spectinomycin (Spt), and to verify the presence of mutations in resistance genes.

Methods: Antibiotic susceptibility testing was performed by Etest method on 30 N. gonorrhoeae isolates collected from the MSM (men who have sex with men) population.
