A CAMINHO DA VACINA

E. coli, um dos micróbios causadores da cistite em mulheres. “Esse micro-organismo penetra na bexiga e, ao roubar ferro das células, sintetiza toxina capazes de lesá-las”, descreve o microbiologista Harry Mobley, que coordena os estudos. Essa invasão resulta em ardência e dor ao urinar e em uma sensação de bexiga constantemente cheia. Para impedir essa devassa no corpo feminino, o time de Mobley quer decifrar quais proteínas fabricadas durante a infecção podem ser anuladas- o que permitiria a criação de uma vacina. “A grande dificuldade hoje é encontrar as moléculas comuns a todas as variáveis da bactéria”, diz.

Entra no corpo também por meio de água e alimentos contaminados.O QUE CAUSA: aproveitando uma falha do sistema imune, a bactéria pode provocar infecções nos sistemas urinário e digestivo, além de meningite e infecção generalizada.
