Examples of infection in the following topics:

  • Microorganisms in the Hospital

    • Nosocomial infections can cause severe pneumonia and infections of the urinary tract, bloodstream, and other parts of the body.
    • A nosocomial infection, also known as a hospital-acquired infection or HAI, is an infection whose development is favoured by a hospital environment, such as one acquired by a patient during a hospital visit, or one developed among hospital staff.
    • Such infections include fungal and bacterial infections, and are aggravated by the reduced resistance of individual patients.
    • Nosocomial infections can cause severe pneumonia and infections of the urinary tract, bloodstream, and other parts of the body.
    • HAP is the second most common nosocomial infection (urinary tract infection is the most common), and accounts for 15-20% of the total.
  • The TORCH Panel of Tests

    • TORCH infections are a group of viral, bacterial, and protozoan infections that gain access to the fetal bloodstream from the mother.
    • TORCH complex is a medical acronym for a set of perinatal infections (which are infections passed from a pregnant woman to her fetus).
    • TORCH infections can lead to severe fetal anomalies or even fetal loss.
    • The TORCH panel is valuable for checking for infections because the mother often has a mild infection with few or no symptoms.
    • Hematoxylin and Eosin stain showing cytomegalovirus (CMV) infection of the placenta (CMV placentitis), a TORCH infection.
  • Compromised Host

    • Numerous risk factors in the hospital setting can predispose a patient to infection.
    • A nosocomial infection, also known as a hospital-acquired infection or HAI, is an infection whose development is favoured by a hospital environment, such as one acquired by a patient during a hospital visit or one developing among hospital staff.
    • Such infections include fungal and bacterial infections.
    • Numerous risk factors in the hospital setting predispose a patient to infection.
    • Discuss the risk factors that contribute to the acquiring of nosocomial infections or hospital-acquired infections
  • Urinary Tract Infection (UTI)

    • A urinary tract infection (UTI) is an infection affecting the urinary tract; about 150 million people develop UTIs each year.
    • Up to 10% of women have a urinary tract infection in a given year and half of women having at least one infection at some point in their lives.
    • A urinary tract infection (UTI) is an infection that affects part of the urinary tract.
    • Kidney infection, if it occurs, usually follows a bladder infection but may also result from a blood-borne infection.
    • Lower urinary tract infection is also referred to as a bladder infection.
  • Infection

    • An infection is the invasion of tissues by disease-causing microorganisms; two common infections of the skin are athlete's foot and herpes.
    • Hosts normally fight infections themselves via their immune system.
    • Pharmaceuticals can also help fight infections.
    • Hygiene plays an important role in managing an athlete's foot infection.
    • Oral herpes is the most common form of infection.
  • Gonorrhea

    • Gonorrhea (also colloquially known as the clap) is a common human sexually transmitted infection.
    • Such infection is asymptomatic in 90% of cases, and produces a sore throat in the remaining 10%.
    • The infection is transmitted from one person to another through vaginal, oral, or anal sex.
    • Men have a 20% risk of getting the infection from a single act of vaginal intercourse with an infected woman.
    • Women have a 60–80% risk of getting the infection from a single act of vaginal intercourse with an infected man.
  • Viruses of Archaea

    • The second single stranded DNA virus infecting Archaea is Aeropyrum coil-shaped virus (ACV).
    • A virus infecting archaea was first described in 1974.
    • Two groups of single-stranded DNA viruses that infect archaea have been recently isolated.
    • Species of the genus Salterprovirus infect halophilic archaea species of the Euryarchaeota.
    • Cell of Sulfolobus infected by virus STSV1 observed under microscopy.
  • Immunodeficiency

    • Immunodeficiency occurs when the immune system cannot appropriately respond to infections.
    • Human immunodeficiency virus infection / acquired immunodeficiency syndrome (HIV/AIDS), is a disease of the human immune system caused by infection with human immunodeficiency virus (HIV) .
    • During the initial infection, a person may experience a brief period of influenza-like illness.
    • The person has a high probability of becoming infected, including from opportunistic infections and tumors that do not usually affect people who have working immune systems.
    • This weakens the immune system, allowing opportunistic infections.
  • Neutralization Reaction

    • The antibody response is crucial for preventing many viral infections and may also contribute to the resolution of an infection.
    • A subset of these antibodies can block viral infection by a process called neutralization.
    • This virus-antibody complex can prevent viral infections in many ways.
    • Antibodies can also neutralize viral infectivity by binding to cell surface receptors.
    • Neutralizing antibodies have shown potential in the treatment of retroviral infections.
  • Cystitis

    • Cystitis is a urinary bladder inflammation that is most commonly caused by a bacterial infection of the lower urinary tract infection.
    • A urinary tract infection (UTI), a bacterial infection that affects the lower urinary tract, is also known as a simple cystitis (a bladder infection).
    • It is most commonly caused by a bacterial infection in which case it is referred to as a urinary tract infection.
    • The cause of EC may be attributed to infection by Schistosoma haematobium or by certain medications in afflicted children.
    • This disease can cause chronic urinary tract infections.
