Penicillin News and Research

RSS

Penicillin (sometimes abbreviated PCN or pen) is a group of antibiotics derived from ''Penicillium'' fungi. Penicillin antibiotics are historically significant because they are the first drugs that were effective against many previously serious diseases such as syphilis and Staphylococcus infections.

Unusual type of antibiotic shows promise in defeating deadly "superbugs"

An unusual type of antibiotic being developed by chemists at Notre Dame University shows promise in defeating deadly "superbugs" - highly drug-resistant staph bacteria that are an increasing source of hospital-based infections.

British scientist who discovered link with smoking and cancer, dies at 92

The British scientist Sir Richard Doll, who was the first scientist to expose the link between smoking and lung cancer, has died in hospital, after a short illness; he was 92.

Use of antibiotics increases risk of developing antibiotic resistance

A new study has shown that a prescription of antibiotics taken within the previous two months doubles the chances of patients carrying antibiotic resistant bacteria. The same effect was not seen in patients who had had antibiotics prescribed within the previous 12 months.

If global efforts to prevent HIV/AIDS are to work long term, they must avoid suspicions of being unfair

Johns Hopkins infectious disease specialists who have spent more than two decades leading efforts to combat HIV and AIDS worldwide are warning that limited international relief supplies of antiretroviral therapies currently being distributed in Africa, Asia and the Caribbean will not get to those who can least afford to pay for them.

12 deaths creates new infection scare in UK hospitals

There have been some 300 cases of Clostridium difficile in 18 months at Stoke Mandeville Hospital, in Aylesbury, Bucks, a national centre for spinal injury, and it is thought that the infection was an "actual or probable" factor in 12 deaths in that time.

As syphilis rates increase in Los Angeles County, new study suggests the disease is increasing HIV rates

The syphilis epidemic among men who have sex with men in Los Angeles County may be contributing to rates of HIV in this population, according to a new report published in the Journal of Acquired Immune Deficiency Syndrome.

Hormonal contraceptives increase risk of HSV-2 transmission

Women who are infected with herpes simplex virus type 2 (HSV-2) may have an increased risk of transmitting the virus to others if they use hormonal contraceptives or have certain bacterial vaginal infections, according to an article in the May 15 issue of Clinical Infectious Diseases, now available online.

Community MRSA is re-emergence of 1950's pandemic

This "re-equipping and re-emergence" of a clone that caused a pandemic 40-50 years ago could mean that community acquired MRSA will spread faster and be more widespread than previously expected, warns an international team of researchers who have been studying the bacteria.

Bacteria's rising threat studied

Infectious diseases researchers at Vanderbilt University Medical Center are noticing a significant increase in the number of infections due to Methicillin-Resistant Staphylococcus Aureus (MRSA), and the number of asymptomatic individuals who harbor the organism in their bodies.

Drug-resistant bacteria MRSA a growing threat

Infectious diseases researchers at Vanderbilt University Medical Center are noticing a significant increase in the number of infections due to Methicillin-Resistant Staphylococcus Aureus (MRSA) and the number of asymptomatic individuals who harbor the organism in their bodies.

Penicillin V and erythromycin have no benefit for most adults with acute laryngitis

Two common antibiotics, Penicillin V and erythromycin, appear to have no benefit for most adults with acute laryngitis, says a research team led by Dr. Ludovic Reveiz of Bogota, Colombia.

Protein discovery with medical implications

It was a transforming moment. Researchers could barely believe their eyes. A molecular blob of a protein reshaped itself into a molecular Pacman in order to free new viruses from the inside of a bacterial cell.

Antibiotics protect nerves in mice by turning on genes

A family of antibiotics that includes penicillin may help prevent nerve damage and death in a wide variety of neurological diseases, including Lou Gehrig's disease, dementia, stroke, and epilepsy, Johns Hopkins researchers have found.

Nanoscale switch could serve as sensor, medical tool

Improving significantly on an early prototype, Johns Hopkins University researchers have found a new way to join two unrelated proteins to create a molecular switch, a nanoscale "device" in which one biochemical partner controls the activity of the other.

Discovery of compound that renders the MRSA superbug vulnerable to antibiotics

MRSA- methicillin-resistant Staphylococcus aureus- is defined by its ability to resist the antibiotic methicillin. Like penicillin, methicillin works by blocking bacterial enzymes called PBPs, which normally strengthen cell walls by forming cross links.

Virginia Department of Health and the Get Smart Virginia program are urging consumers to become educated this cold and flu

Additionally, Governor Mark Warner has declared October 2004 Antibiotic Awareness Month in an effort to increase the public’s knowledge about the growing problem of resistance to antibiotic medications.

Pneumonia could be treatable by the oral antibiotic amoxicillin rather than injectable penicillin

Pneumonia - one of the world’s deadliest diseases for young children in developing countries - could be treatable by the oral antibiotic amoxicillin rather than injectable penicillin, with implications for better health outcomes and reduced costs

Severe infections with flesh-eating bacteria are considerably more common than expected

In an EU project covering 11 countries, headed by Lund University in Sweden, it was calculated that some 1,000 cases would be found over an initial 1½-year period. Fully 5,000 were identified.

Growing crisis of antibiotic-resistant bacteria

Scientists, the federal government and the pharmaceutical industry must work together quickly to solve the growing crisis of antibiotic-resistant bacteria, a Virginia Commonwealth University infectious disease expert said in today's issue of The New England Journal of Medicine.

Natural organohalogens have potent anticancer and antibacterial activity

Human made chemical compounds called organohalogens get loads of attention as they are best known for their often harmful effect on the environment - substances like the CFCs (the ozone-damaging chemicals), dioxin (found in the herbicide Agent Orange), PCBs (industrial fluids) and several pesticides.
