Brazilians fight dengue with bacteria

Dengue epidemics continue to break out in South America. Last year, more than 100,000 people contracted dengue fever in Rio de Janeiro alone. In its fight against the deadly virus, the city is employing unique methods.

The endless battle against Rio de Janeiro's mosquitoes takes Luciano do Campos Lobo to dark courtyards in Rio de Janeiro's cramped favelas and to its luxurious villas, hidden away behind imposing iron gates and walls. Armed with a clipboard, Luciano knocks on doors and stomps around abandoned parks, on the lookout for eggs, larvae and mosquitoes.

Today, Luciano is fighting to make himself heard over the din of the many taxis and busses speeding along the busy road. As he yells into a crackling intercom, a little old lady teeters past, dragging a manicured poodle on a leash behind her. She eyes Luciano's black beard and heavy boots and gives a disappointed sniff as she disappears into the gleaming white tower block.
