- Bacterial infections typically present with localized redness and heat, inflammation (swelling) and pain. Bacterial infections tend to present localized pain more frequently than viral infections (not always). Even with a throat infection, a bacterial one will usually have more severe pain on one side of the throat.n example could be some skin bacteria and yeast. Antibiotics may, in fact, upset the balance by destroying the good bacteria, allowing the other potential pathogen to multiply faster and cause health problems. Infections caused by a virus.

What are Some Causes of Infections? Fungus is also a common cause of infections, including ringworm, Athlete’s foot, fungal nail infections, and vaginal yeast. Fungal types are caused by fungus that has either been transmitted through contact or has grown as a result of certain conditions of the body.iruses usually infect a specific type of cell, which causes viral infections to affect certain parts of the body. A cold is the most common type and generally affects the upper respiratory tract. Influenza is another common infection, but symptoms can affect the entire body. Ad.

Bacterial and Viral Infections Bacterial and viral infections have many things in common. Both types of infections are caused by microbes -- bacteria and viruses, respectively -- and spread by things such as: 1  Coughing and sneezing. 2  Contact with infected people, especially through kissing and sex. 3  Contact with contaminated surfaces, food, and water.

About common vaginal infections Vaginal infections occur when bacteria, fungi or viruses grow in and around the vaginal area. Anything that lowers the acidity of the vagina can cause a vaginal infection, while some other infections are transferred by sexual contact. Vaginal infections are common.

Human Physiology/Print Version The root cause of septicemia is a bacterial infection (typically severe) in another part of the body. Urinary tract infections, lung infections, and infections in the abdominal area are all potential causes of septicemia. Bacteria from these infections enter the bloodstream and multiply, causing immediate symptoms.he root cause of septicemia is a bacterial infection (typically severe) in another part of the body.

- Bacteria cause bacterial infections and viruses cause viral infections. Antibiotic drugs usually kill bacteria, but they are not effective against viruses. Infections caused by bacteria include strep throat, tuberculosis and urinary tract infections. Diseases caused by viruses include chickenpox, AIDS and common colds.

Meningitis About Meningitis. Meningitis is most often caused by a bacterial infection. It also may be caused by a virus, fungal infection, parasite, a reaction to certain medications or medical treatments, a rheumatologic disease such as lupus, some types of cancer, or a traumatic injury to the head or spine.acterial meningitis is a rare but potentially fatal disease. It can be caused by several types of bacteria that first cause an upper respiratory tract infection and then travel through the blood stream to the brain.

Overview Causes of heart infection. Heart infections, such as pericarditis, endocarditis and myocarditis, are caused when an irritant, such as a bacterium, virus or chemical, reaches your heart muscle. The most common causes of heart infections include: 1  Bacteria. 2  Viruses.3  Parasites.he cause of cardiomyopathy, a thickening or enlarging of the heart muscle, may depend on the type: 1  Dilated cardiomyopathy. 2  The cause of this most common type of cardiomyopathy often is unknown. 3  It may be caused by reduced blood flow to the heart (ischemic heart disease), infections, toxins and certain drugs.

Bacterial Diseases Staphylococcus aureus causes a variety of infections in the body, including boils, cellulitis, abscesses, wound infections, toxic shock syndrome, pneumonia, and food poisoning. Streptococcal bacteria cause a variety of infections in the body, including pneumonia, meningitis, ear infections, and strep throat.Bacterial diseases are contagious and can result in many serious or life-threatening complications, such as blood poisoning (bacteremia), kidney failure, and toxic shock syndrome.armful bacteria may also emit toxins that damage the body. Common pathogenic bacteria and the types of bacterial diseases they cause include: Escherichia coli and Salmonella cause food poisoning. Helicobacter pylori cause gastritis and ulcers.

Warning: 1 Several infections may be spread by direct contact with blood if there is a break in the skin (blood to blood) or direct contact with mucous membranes (i.e. eye, mouth). Infections are caused by bacteria, viruses and other microscopic organisms. 2  These germs are found in the environment (water, soil, air) as well as in and on humans, in our body secretions (stool etc.) and in the tiny droplets that are generated by breathing, coughing, sneezing.

Clostridium difficile Infection Clostridium difficile Infection. People getting medical care can catch serious infections called healthcare-associated infections (HAIs). One type of HAI – caused by the germ C. difficile – was estimated to cause almost half a million infections in the United States in 2011, and 29,000 died within 30 days of the initial diagnosis. Those most at risk are people, especially older adults, who take antibiotics and also get medical care.

What are Bacteria? Harmful bacteria can affect almost any area of the body. Other types of bacterial infections include: Bacterial meningitis is a severe infection of the meninges, the lining of the brain. Otitis media is the official name for an infection or inflammation of the middle ear. Both bacteria and viruses can cause ear infections, which commonly occur in babies and small children. Urinary tract infection (UTI) is a bacterial infection of the bladder, urethra, kidneys, or ureters. Respiratory tract infections include sore throat, bronchitis, sinusitis, and pneumonia. Bacteria or viruses may be responsible for respiratory tract infections.

Welcome to Infectious Diseases Conferences Infectious diseases kill more people worldwide than any other single cause. Infectious diseases are caused by germs. Germs are tiny living things that are found everywhere - in air, soil and water. You can get infected by touching, eating, drinking or breathing something that contains a germ. Germs can also spread through animal and insect bites, kissing and sexual contact.

Germs: Understand and protect against bacteria, viruses and infection Many disease-causing bacteria produce toxins — powerful chemicals that damage cells and make you ill. 1  Other bacteria can directly invade and damage tissues. Some infections caused by bacteria include: 2  Strep throat. 3  Tuberculosis. 4  Urinary tract infections.

- Urinary Tract Infections (UTIs) Urinary tract infections (UTIs) are a common type of infection caused by bacteria (most often E. coli) that travel up the urethra to the bladder. A bladder infection is called cystitis. If bacterial infection spreads to the kidneys and ureters, the condition is called pyelonephritis.
