Scientists fear that migratory birds can spread difficult-to-treat infections after discovering that gulls and grues are carrying bacteria that are resistant to antibiotics. Portuguese researchers analyzed 57 samples of Silver Fever stools.
One in ten of these contained a bacterium resistant to the powerful antibiotic vancomycin.
According to scientists in the journal Proteome Science, birds are probably intercepting infections while eating disposed residues of human food.
He lived by the rubbish bins, was eating everything that was eating, thrown out of people, but he loved fish most. The Silver Gull is a constant and wandering bird. Its main food is the fish that hunts on the surface of the water. When they find fish passages, seagulls are gathered in flocks of several dozen specimens. Sometimes he diversifies his food with mycelial rodents – plums, mice, phyllons, water rats and others. He often feeds on dead fish, crustaceans and plant waste dumped by the sea.
The growth period begins in March. It nests on roofs of buildings, on rocks and rarely on sand away from settlements. The nest is made of branches and grass. The female lays 2 to 4 silvery blue eggs with dark gray and dark brown spots, which mate with the male for about 3 weeks. Parents feed the little ones with fish by polluting the half-fed food in the beak of the little or the ground and swallowing it from there. The little ones are very greedy. They grow fast and after 40 – 45 days they make their first attempts to fly. In the autumn, the entire family leaves the nest and wanders along the coast. As wild birds, not pets, they have no direct access to antibiotics, scientists say. That’s why they’re “guilty” without asking people.
Researchers warn that long-range migratory birds can spread antibiotic resistance from place to place to other animals and people who have unintentional access to their stools.
Superbacteria are relatively harmless to healthy people, but can be very dangerous for the chronically ill, the elderly and children with weaker organisms and the immune system.
