Staph ‘gangs’ share nutrients during infection

Staph ‘gangs’ share nutrients during infection

Antibiotic-resistant bacteria can share resources to cause chronic infections, Vanderbilt investigators have discovered. Like the individual members of a gang who might be relatively harmless alone, they turn deadly when they get together with their “friends.” The findings, reported Oct. 8 in Cell Host & Microbe , shed light on a long-standing question in infectious diseases and may inform new treatment strategies, said Eric Skaar, Ph.D., MPH, Ernest W Continue reading

Defective gene renders diarrhea vaccine ineffective

Defective gene renders diarrhea vaccine ineffective

Acute diarrheal illnesses cause nearly one-fifth of all child deaths in developing countries. The most common cause is rotavirus. Continue reading

Oral capsule as effective as invasive procedures for delivery of fecal transplant

Oral capsule as effective as invasive procedures for delivery of fecal transplant

A noninvasive method of delivering a promising therapy for persistent Clostridium difficile ( C. difficile ) infection appears to be as effective as treatment via colonoscopy or through a nasogastric tube Continue reading

Pneumococcal vaccine reduces antibiotic-resistant infections in children by 62 percent

Pneumococcal vaccine reduces antibiotic-resistant infections in children by 62 percent

The pneumococcal vaccine recommended for young children not only prevents illness and death, but also has dramatically reduced severe antibiotic-resistant infections, suggests nationwide research being presented at IDWeek 2014™. Continue reading

Pneumococcal vaccine reduces antibiotic-resistant infections in children by 62 percent

The pneumococcal vaccine recommended for young children not only prevents illness and death, but also has dramatically reduced severe antibiotic-resistant infections, suggests nationwide research being presented at IDWeek 2014™. Pneumococcal infection — which can cause everything from ear infections to pneumonia and meningitis — is the most common vaccine-preventable bacterial cause of death Continue reading

College athletes in contact sports more likely to carry MRSA, study finds

College athletes in contact sports more likely to carry MRSA, study finds

Even if they don’t show signs of infection, college athletes who play football, soccer and other contact sports are more likely to carry the superbug methicillin-resistant Staphylococcus aureus (MRSA), suggests a study on MRSA and athletes, which is being presented at IDWeek 2014™. This puts them at higher risk for infection and increases the likelihood of spreading the bug, which can cause serious and even fatal infections. The study is the first to observe college athletes who are not part of a larger MRSA outbreak Continue reading

Effect of antibiotic susceptibility for patients with bloodstream infection

Effect of antibiotic susceptibility for patients with bloodstream infection

In an analysis of more than 8,000 episodes of Staphylococcus aureus bloodstream infections, there were no significant differences in the risk of death when comparing patients exhibiting less susceptibility to the antibiotic vancomycin to patients with more vancomycin susceptible strains of S.

Investigation into GI scope-related infections changes national guidelines

Investigation into GI scope-related infections changes national guidelines

National guidelines for the cleaning of certain gastrointestinal (GI) scopes are likely to be updated due to findings from UPMC’s infection prevention team. Continue reading

Programs to improve hand hygiene reduced infections, increased compliance

Programs to improve hand hygiene reduced infections, increased compliance

UPMC Presbyterian Hospital’s infection prevention teams have improved hand washing and sanitizing compliance at the hospital to nearly 100 percent among clinical staff through accountability and educational measures. In a separate effort at UPMC Mercy Hospital, rates of a deadly infection were reduced by educating patients about hand hygiene. Continue reading

Dynamic motion of HIV as it readies an attack: Seen in real time, for the first time

Dynamic motion of HIV as it readies an attack: Seen in real time, for the first time

Researchers at Weill Cornell Medical College have developed technologies that allow investigators, for the first time, to watch what they call the “dance” of HIV proteins on the virus’ surface, which may contribute to how it infects human immune cells. Their discovery is described in the Oct. 8 issue of Science , and is also a part of a study published the same day in Nature Continue reading
