Summary:
Sampling of pigeons captured on the streets of Madrid has revealed the bacterial pathogens they carry. Researchers found two bugs that were highly prevalent in the bird population, Chlamydophila psittaci and Campylobacter jejuni, both of which cause illness in humans.

Sampling of pigeons captured on the streets of Madrid has revealed the bacterial pathogens they carry. Researchers writing in BioMed Central's open access journal Acta Veterinaria Scandinavica found two bugs that were highly prevalent in the bird population, Chlamydophila psittaci and Campylobacter jejuni, both of which cause illness in humans.

Fernando Esperσn from the Animal Health Research Center, Madrid, Spain, worked with a team of researchers to analyse blood and enema samples taken from 118 pigeons caught using gun-propelled nets.

He said, "The present study demonstrates the extremely high prevalence of two zoonotic pathogens in feral pigeons in Madrid. At the same time, infection with these pathogens did not appear to be associated with any harmful clinical signs in the birds themselves. This leads to the hypothesis that pigeons act as asymptomatic reservoirs of Chlamydophila psittaci and Campylobacter jejuni. These birds may therefore pose a public health risk to the human population."

Chlamydophila psittaci was found in 52.6% of the pigeons captured, while Campylobacter jejuni was present in 69.1%. Although there have been few reports of disease transmission between pigeons and humans, it can occur by aerosols, direct contact or indirect contact through food and water contamination.

According to Esperσn, "Thermophilic Campylobacter species are considered the primary pathogens responsible for acute diarrhea in the world. In fact, in many countries such as England and Wales, Canada, Australia and New Zealand Campylobacter jejuni infection causes more cases of acute diarrhea than infection by Salmonella species."

Gilead's $1000-a-Pill Drug Could Cure Hep C in HIV-Positive People

Gilead's $1000-a-Pill Drug Could Cure Hep C in HIV-Positive People

TheStreet (July 21, 2014) — New research shows Gilead Science's drug Sovaldi helps in curing hepatitis C in those who suffer from HIV. In a medical study, the combination of Gilead's Hep C drug with anti-viral drug Ribavirin cured 76% of HIV-positive patients suffering from the most common hepatitis C strain. Hepatitis C and related complications have been a top cause of death in HIV-positive patients. Typical medication used to treat the disease, including interferon proteins, tended to react badly with HIV drugs. However, Sovaldi's %1,000-a-pill price tag could limit the number of patients able to access the treatment. TheStreet's Keris Lahiff reports from New York. Video provided by TheStreet
