The onchocerciasis parasite showing signs of resistance

01-31-2008 · EurekAlert!

Onchocerciasis is a parasitic infection brings about skin lesions and severe eye damage that might lead to irreversible blindness. A study published recently by IRD scientists, who monitored a cohort of patients treated with ivermectin, the sole drug used for curing infected people, found fertility-change associated genetic selection in parasite populations. Although the results do not prove with absolute certainty that Onchocerca volvulus is steadily becoming resistance to ivermectin, they do show that certain parasites are more sensitive to treatment than others.

Ivermectin is causing genetic selection in river blindness parasite
08-29-2007 · EurekAlert!
Recent reports of patients failing to respond to ivermectin, the standard drug for treating river blindness (onchocerciasis), have suggested the emergence of drug-resistant Onchocerca volvulus (the parasite that causes river blindness). According to a new study by Roger Prichard of McGill University, Canada, Ivermectin is causing genetic changes in the parasite.

Natural Sciences and Engineering Research Council grantee Peter Austin and three other researchers have just completed a survey of hospital visits in Ontario, Canada, showing that, compared to people born under other astrological signs, Virgos have an increased risk of vomiting during pregnancy, Pisces have an increased risk of heart failure, and Libras have an increased risk of fracturing their pelvises. In fact, each of the 12 astrological signs had at least two associated medical disorders.

Cognitive impairment link found in popular medications
08-02-2007 · EurekAlert!
Long-term use of histamine2 receptor antagonists, one class of drugs that blocks stomach acid, may be associated with cognitive impairment in older African-American adults. According to an Indiana University School of Medicine and Regenstrief Institute study published in August issue of the Journal of the American Geriatrics Society, the risk for showing signs of cognitive impairment is 2.5 times greater for patients using these medications long-term.

Malaria: Efficacy of monotherapies in Cameroon
10-13-2006 · EurekAlert!
Since the 1980s parasite forms have been appearing that are resistant to the main antimalarial treatments prescribed in the African countries. In Cameroon, where tracing the changes and developments of resistance is complicated by a diversity of landscapes and climates, IRD researchers and their OCEAC (Organisation de Coordination pour la lutte contre les endémies en Afrique Centrale) partners compared, between 1999 and 2004, the efficacy of three standard monotherapies (chloroquine, amodiaquine and sulfadoxine-pyrimethamine) in children from 12 different localities.

Studies Identify Food Sources Of Disease And Drug Resistance

As the recent US outbreak of E. coli infections caused by contaminated spinach demonstrates, the safety of the food we eat cannot be taken for granted. Two studies in the November 1 issue of the Journal of Infectious Diseases, now available online, further illustrate the point, one adding a new bacterial culprit to the mix and the other showing that use of antibiotics as growth promoters in livestock increases the risk of antibiotic resistance in humans.
