Parasitic diseases are the foremost worldwide health problem today, particularly in the under developed countries. It is estimated that the global prevalence of some of these diseases already exceeds 60% among the m ...
Parasitic diseases in rabbits and their prevention methods. Rabbits serve not only as an important animal species for biomedical research but also as a common food source for people throughout th ...
Parasitic diseases of the central nervous system (CNS) contribute extensively to morbidity and mortality in the developing world and in industrialized nations with a high immigrant influx of people from endemic area ...
Parasites are organisms that live off other organisms, or hosts, to survive. Some parasites don’t noticeably affect their hosts. Others grow, reproduce, or invade organ systems that make their hosts sick, resulting ...
Parasites are living things that use other living things - like your body - for food and a place to live. You can get them from contaminated food or water, a bug bite, or sexual contact. Some parasitic diseases are easil ...
oncogenic drivers, are common in tissues starting at a young age. These observations raise the question: how do we largely avoid cancer for most of our lives? Here we propose that evolutionary forces can help explain this paradox. As humans and ot ...
oncogenesis has produced an advanced cancer, tumor cells have undergone extensive evolution. The cellular phenotypes resulting from this evolution have been well studied, and include accelerated growth rates, apoptosis r ...
oncogenesis itself, which we define as the process by which normal cells acquire the characteristics of cancer cells. This definition encompasses the changes that occur prior to and after the threshold of cancer is reach ...
Viruses and bacteria are two types of potentially disease-causing (pathogenic) particles. Viruses are much smaller than bacteria and can't reproduce without the assistance of a host. Bacteria are capable of reproducing on their own. The sympto ...
A viral infection is a proliferation of a harmful virus inside the body. Viruses cannot reproduce without the assistance of a host. Viruses infect a host by introducing their genetic material into the cells and hijacking ...
viruses can also be spread through contaminated objects, such as doorknobs, tabletops, and personal items. If you touch one of these objects and then touch your nose or eyes, you could develop a disease. Respiratory vira ...
Vaccines can help prevent you from getting many viral diseases. Not all viral diseases are contagious. This means they aren’t always spread from person to person. But many of them are. Common examples of contagious viral diseases includ ...
Viruses are very tiny germs. They are made of genetic material inside of a protein coating. Viruses cause familiar infectious diseases such as the common cold, flu and warts. They also cause severe illnesses such as HIV/AI ...

Influenza viruses are assumed to be transmitted predominantly by aerosol infection, i.e. relatively large droplets (>5 μm) created particularly while talking, coughing, or sneezing, thus entering the mucosae throug ...
The variability of the type B viruses, however, is also characterised by other mechanisms such as insertion and deletion, as the influenza B lines show which have been co-circulating and stable for more than 20 years The ...
Influenza virus as an enveloped virus is relatively vulnerable to damaging environmental impacts. Depending on environmental conditions (e.g. humidity and temperature), however, it can survive up to several hours and in water at low temperatures ( ...
The HA is synthesized as precursor protein and cleaved by cellular serine proteases into the functional proteins HA1 and HA2. The amino acid sequence at the cleavage site determines HA processing by cellular proteases an ...
Influenza viruses are members of the family Orthomyxoviridae. This family represents enveloped viruses the genome of which consists of segmented negative-sense single-strand RNA segments. There are four genera of this fa ...
HIV is a virus that attacks cells in the immune system, which is our body’s natural defence against illness. The virus destroys a type of white blood cell in the immune system called a T-helper cell, and makes copi ...
