Microbiology Quiz: Neisseria Species

Gram-negative bacteria shaped like spheres.

A genus of gram-negative, aerobic cocci bacteria.

A pathogenic Neisseria species causing gonorrhea.

A pathogenic Neisseria species causing meningitis.

Sexually transmitted infection caused by N. gonorrhoeae.

Gram-negative bacteria shaped like rods.

Bacteria needing oxygen for growth.

Bacteria that don't need oxygen for growth.

Acute infection characterized by yellow, purulent urethral discharge and painful urination.

Symptoms include greenish-yellow cervical discharge and possible intermenstrual bleeding, progressing to potential salpingitis, PID, and fibrosis.

Gonococcal infection of the newborn's conjunctiva acquired during childbirth.

Frequent cause of meningitis, potentially leading to meningococcemia with shock.

Pili enhance attachment to host epithelial and mucosal cells.

Occur frequently in winter/early spring due to close contact; also occur in developing nations.

Can lead to infertility due to tubal scarring from salpingitis and PID.

Bacteria, like gonococcus, are highly sensitive to dehydration, so they don't survive long outside the human body.

The bacterium Neisseria meningitidis, responsible for causing meningitis and septicemia.

A serious infection of the meninges, the membranes surrounding the brain and spinal cord, caused by Neisseria meningitidis.

A life-threatening blood infection caused by Neisseria meningitidis, leading to rapid bacterial multiplication in the bloodstream.

The outer layer of Neisseria meningitidis that prevents it from being engulfed and destroyed by immune cells (phagocytes).

The presence of Neisseria meningitidis in the bloodstream, a stage leading to meningococcal meningitis or septicemia.

A rapidly progressing and severe form of septicemia, often fatal if untreated.

A vaccine containing capsular polysaccharides from Neisseria meningitidis serogroups A, C, W-135, and Y, protecting against these specific strains.

A type of meningococcal conjugate vaccine that protects against serogroups A, C, W-135, and Y.

A bacterial genus known for causing infections in various parts of the body, including the respiratory system, middle ear, eyes, central nervous system, and joints.

A genus of non-motile, coccobacillus bacteria that are often responsible for hospital-acquired infections (nosocomial infections).

A group of bacteria found in the gastrointestinal tract of humans and animals. These bacteria are facultative anaerobes, meaning they can grow in the presence or absence of oxygen. They contain lipopolysaccharide (LPS), also known as endotoxin.

A family of gram-negative, facultative anaerobic bacteria that includes both pathogenic and non-pathogenic species. They are commonly found in the intestines of humans and animals.

A genus of bacteria that commonly causes infections in the gastrointestinal tract, leading to food poisoning and other illnesses.

A type of bacteria that normally resides in the colon but can cause various infections both within and outside the gastrointestinal tract. It is known for its fimbriae (pili) used for attaching to host mucosal surfaces.

A microorganism that causes disease only under specific conditions, such as a weakened immune system or when introduced to a normally sterile body site.

Hair-like structures on the surface of some bacteria that help them attach to host cells, often contributing to the development of infections.

Enterotoxigenic E. coli, a common cause of traveler's diarrhea, spreading through contaminated food, water, or person-to-person contact.

Enteropathogenic E. coli, a significant cause of diarrhea in infants, especially in areas with inadequate sanitation.

Enterohemorrhagic E. coli, producing verotoxin (Shiga-like toxin) leading to bloody diarrhea (hemorrhagic colitis) and potentially life-threatening kidney failure (HUS).

A particularly dangerous E. coli strain combining features of EAEC and EHEC, leading to severe complications.

Enteroinvasive E. coli, causing dysentery-like symptoms like fever and bloody stools.

Enteroaggregative E. coli, causing traveler's diarrhea and persistent diarrhea in young children.

E. coli is a primary cause of urinary tract infections (UTIs), including cystitis and pyelonephritis, with women being particularly susceptible.

E. coli can cause disease in sterile sites like the bladder or bloodstream, even if it's normally harmless in the intestines.

A severe infection of the membranes surrounding the brain and spinal cord, affecting newborns within the first month of life. E. coli is a major cause.

An infection acquired during a hospital stay, often from exposure to pathogens in the hospital environment.

A bacterial infection that can cause both intestinal and extraintestinal diseases, including gastroenteritis and typhoid fever.

A severe and life-threatening systemic illness caused by Salmonella Typhi, characterized by high fever, abdominal symptoms, and potential complications.

E. coli is a major cause of meningitis in infants within the first month of life.

Salmonella can cause a range of illnesses including gastroenteritis (food poisoning) and typhoid fever.

Symptoms include nausea, vomiting, diarrhea, fever, and abdominal cramping.

A serious illness with fever, abdominal pain, and potentially a rash. Primarily caused by S. Typhi.

These bacteria are curved or S-shaped and can cause infections in the intestines.

Shigella causes bacillary dysentery, a human intestinal disease common among young children.

Vibrio bacteria are short, curved, and rod-shaped.
