2 Type Harmful Insect Hidden In Pigeon

A number of researchers who study the dove found that the bird was carrying two insects that cause disease. This makes the dove is considered dangerous for human health. The result of the discovery team of Spanish researchers suggest that although the bacteria can be harmful to humans, they seem to not harm the bird.
Pigeons, which are considered 'rats with wings' for which they consider spreaders of disease, could act as 'reservoirs' for harmful insects.
"Animals that live close to humans could have a store of pathogens harmful to humans," wrote Fernando Esperon of Animal Health Research Center in Madrid, who led the study, told Reuters on Tuesday (22 / 6). "Therefore, these birds have an increased risk of disease in human populations.''
Residents in cities like London, Venice, New York, San Francisco, tend to have a good-bad relations with millions of pigeons in the city that dominates the town plazas, sidewalk cafes, and many monuments.
Their droppings littering the Trafalgar Square in London, St Mark's Square in Venice, and Times Square in New York, where they used to eat food nonstop and pieces of bread.
For the study, published in the journal BioMed centeral, Acta Veterinaria Scandinavica, Esperon and his colleagues analyzed 118 pigeons was caught using nets loaded gun from the Madrid urban area to find the prevalence of bacteria that are known to cause disease in humans.
They find insects called Chlamydophila psittaci in pigeons captured 52.6 percent, and other insects named Campylobacter jejuni at 69.1 percent.
Psittacosis infection in humans tends to begin with flu-like symptoms and developed into pneumonia, life-threatening. According to Esperon, insects of campylobacter species is one of the main causes of acute diarrhea in the world. "In fact, in many countries such as England and Wales, Canada, Australia and New Zealand, cases of acute diarrhea caused by campylobacter jejuni infection more than spesien infections due to salmonella," wrote Esperon.
Should other insects, bacteria, salmonella can cause fever, diarrhea, nausea and vomiting in patients. The researchers said, although the bird did not look sick by the bacteria, they potentially spread the bacteria to humans. "These data must be considered to control the pigeon population," said Esperon.
