Human papillomavirus infection and vaccination

Human papillamoavirus (HPV) is an infection that can be sexually transmitted. A person can get HPV by having vaginal, anal, or oral sex with another person who has the virus. HPV infections are the most common sexually

Adenovirus infection in children with bronchiolitis or recurrent wheezing

Adenovirus (AdV) and other viruses as Respiratory Syncytial Virus (RSV), Meta-pneumovirus (MPV), Rhinovirus (RV) and Para-influenza Virus (PIV) have been detected in the respiratory tract of children with acute bronchiolitis and recurrent wheezing. Adenovirus (AdV) is an

Understanding mechanisms of salt tolerance for reducing listeria monocytogenes growth in food

Human listeriosis is a serious foodborne disease caused by Listeria monocytogenes, a bacterium often called Listeria. The disease primarily affects older adults, pregnant women, newborns, and adults with weakened immune systems. After consumption of contaminated food, Listeria

Tracking down the cells that produce cancers of the tonsil caused by HPV infection

The cells that cover the inside and outside surfaces of many adult tissues are called epithelia. The cells most external to the tissue usually don’t survive very long and must be therefore be continuously replaced. This is

Schistosomiasis infection: is it really diagnosed?

Schistosomiasis, also known as Bilharziazis, has been and remains one of the most common parasitic diseases worldwide. It affects millions of people in the developing world, mainly in Africa. In 1999, the WHO estimated schistosmiasis as the

Morgellons disease: the search for a perpetrator

Morgellons disease is a poorly understood skin condition associated with Lyme disease. Patients suffering from the disease often have spontaneously-appearing, slowly-healing skin ulcers and may have crawling or stinging sensations in their skin. They may have one

Counteracting a host factor allows adenovirus infection to progress to new virus production

Viruses use the cells of another organism to reproduce and spread. Although very variable in size, the genetic material of a virus is usually tiny in comparison to that of its host and so cannot specify very

Is the post-polio syndrome due to chronic poliovirus infection?

Over the years, poliomyelitis survivors may experience e progressive decline of physical strength accompanied by intolerance to cold, chronic pain and other disabilities. This condition, termed post-polio syndrome (PPS), may lead to the incapacity of living an

What type of immune responses are needed to control HIV infection?

Human immunodeficiency virus-1 (HIV-1) infection can be controlled by antiretroviral therapy (ART) for long periods of time, preventing the development of HIV-induced immunodeficiency and AIDS. However, HIV-1 infection cannot be eradicated from immune cells by ART and

Finding therapeutic way to eradicate tuberculosis of the brain

Tuberculosis is one of oldest infectious disease in the world. It is caused by a bacterium called Mycobacterium tuberculosis, where it infects primarily the lung. Millions of individuals are infected with Mycobacterium tuberculosis. Even though we are

Filamentous bacteriophage organize bacterial biofilms into liquid crystals

At sites of chronic infection, bacteria form biofilms, clusters of bacteria encased within a slimy, polymer-rich coating called the matrix. Biofilms are of concern because bacteria within biofilms become tolerant not only to environmental stresses, but also

Exploiting an ‘Achilles heel’ of DNA replication to arrest viral proliferation

In order to proliferate all organisms need to replicate their genomes. In most, this is achieved by a process named DNA replication by which a parental DNA gives rise to two faithful copies of itself. For this

New test for assessing hospital water quality can lead to fewer patient infections

The bacterium Pseudomonas aeruginosa is an important pathogen that is often found in hospital water systems, from where it can lead to infections of patients, sometimes with severe consequences (e.g. blood infections, and infections in cystic fibrosis

Can germs cause premenstrual syndrome?

Each month a woman’s body prepares itself for pregnancy.  Monthly hormonal cycles alter immunological defenses to allow survival of sperm cells, the fertilized egg, and the developing embryo.   At the onset of each cycle immune defenses are

The drug that can inhibit infection by reovirus

Cellular diversity is, to some extent, determined by the molecules present within specific cells. For example, cells that make up the endothelium, the part of blood vessels that come in contact with blood, make specific proteins that

Post-surgery early aerobic exercise: reduces lung complications and hospital stay

Lung related complications like infections and clots are common after complex abdominal surgery. These have a negative effect on the patient’s recovery, can prolong hospital stay and can even lead to death. We performed a study to

Making a better mouse model to understand the pathogenesis of respiratory syncytial virus infection

Respiratory syncytial virus (RSV) is the number one cause of infant hospitalizations in the United States. RSV infection is very common, with all children infected with this virus at least once by two years of age. Severe

A small step closer to a save new antibiotic

An important fundament of our so called modern medicine are substances that are save for humans to take but deadly for bacteria. They are known as antibiotics. Interestingly, most of these have their origin in microbes, using

Psychological stress can influence key immune activities and an important protein in the response to infection

The central role played by our immune system is to protect us against infections.  In doing so, the immune response creates a localized toxic inflammatory environment that makes it difficult for the infectious agent to survive.  In
