Superbugs: New salmonella strains are resistant to commonly used antibiotics.

Biologists have discovered dozens of new strains of salmonella in Brazil that are resistant to most commonly used antibiotics, Russian satellite network reported Wednesday.
scientists have published their findings and possible ways to fight these "superbugs" in the journal PLoS One.
, a scholar at the University of Sao Paulo in Brazil, said that the university of Sao Paulo, Brazil, had been "very well. "We found that there are large numbers of salmonella strains that are resistant to different antibiotics in both food and humans, suggesting that the risk of an epidemic of food infections in Brazil is now very high," said Fernanda Almeida, chief executive of the university.
"s salmonella caused collective diarrhea and fever in Brazil between 1982 and 2013, and 90 genomes have been deciphered.
however, Almeida and her colleagues found that more than half of the salmonella strains were resistant to one or more antibiotics.
this analysis shows that salmonella has since developed more than 40 genes that make it immune to one or more antibiotics.
some of these genes are obtained autonomously, while others may be "borrowed" from other dangerous bacteria.
, more than half of Brazilian salmonella strains are currently immune to sulfonamide and streptomycin, and a third do not respond to tetracycline and citamycin, and 7 percent are fighting the effects of cephalosporin, known as "antibiotic last hope."
report that a tricky problem that medical experts have increasingly encountered in recent years is "superbugs," microorganisms that are resistant to one or more antibiotics, including rare pathogens as well as some very common and dangerous pathogens such as Staphylococcus aureus and Creagus pneumococcal.
scientists believe that the most common breeding of these microbes are hospitals and farms that speed up the growth of meat and livestock with antibiotics, which have large numbers of potential carriers of the virus, bacteria and antibiotics that force bacteria to evolve, and with the help of antibiotics, "ordinary bacteria" cannot crowd out "superbugs" with weak reproductive capacity.
