2025/2026 QUESTIONS AND ANSWERS GRADED A++
(
✔✔(18) Gas gangrene - ✔✔caused by bacteria that produce gas within the infected
tissue. Toxins produced will cause necrosis; if untreated the condition is fatal.
✔✔(18) Principles of Viral Hemorrhagic Fever (VHF) - ✔✔group of febrile illnesses
ranging in severity from relatively mild to life-threatening. Caused by four distinct viral
families: Arenaviridae, Filoviridae, Bunyaviridae, and Flaviviridae. All VHFs
characterized by fever, overall vascular system damage, and bleeding disorders that
can lead to high fever, shock, and death. Although distributed over much of the world,
many VHFs are present in geographically limited areas and risk of infection is restricted
to those areas.
✔✔(18) Systemic Mycosis - ✔✔fungal infections capable of affecting all internal organs.
Persons with a competent immune system may be asymptomatic or show only minor
symptoms. Immune-compromised patients (including persons with HIV, cancer, or
neutropenia, organ transplant recipients, patients recovering from pancreatitis or
splenectomy, those with diabetes, the very old, and the very young) are at high risk for
infection. Treatment may include adjusting immune-suppressing medications or
administering antifungal medications.
✔✔(18) Visceral leishmaniasis - ✔✔serious form; fatal if untreated.
✔✔(18) Cutaneous leishmaniasis - ✔✔common form; sore forms at fly-bite site; long
healing period (few months to a year).
✔✔(18) Diffuse cutaneous leishmaniasis - ✔✔widespread skin lesions; difficult to treat.
✔✔(18) Mucocutaneous leishmaniasis - ✔✔skin ulcers that spread and can cause
tissue damage to the nose and mouth.
✔✔(16) Who first observed microbes on the teeth? - ✔✔Van Leeuwenhoek
✔✔(16) What causes peptic ulcers? - ✔✔Helicobacter pylori
✔✔(16) What is another word for Bacillary dysentery? - ✔✔Shingellosis, transmitted by
fecal-oral route
✔✔(16) How many known forms of gastroenteritis is caused by E.Coli? - ✔✔Five
, ✔✔(16) What causes Bacillus intoxication ? - ✔✔Bacillus cereus (food poisoning )
caused by prepared foods held without adequate refrigeration for several hours before
serving.
✔✔(16) What is the most common cause of infectious diarrhea in infants and children? -
✔✔Rotavirus
✔✔(16) Calciviruses - ✔✔A group of (+)ssRNA viruses that have been isolated from
birds, cats, dogs, sheep, cows, humans, and are a major cause of grastroenteritis
✔✔(16) Which organism produces afloxoxin, a major carcinogenic substance, causes a
fungus ball? - ✔✔Aspirgillus flavus
✔✔(16) Where does the human pinworm, Enerterobius vermicularis live in humans? -
✔✔Rectum
✔✔(16) Gingivitis - ✔✔A peridontal disease that causes inflammation of the gums.
✔✔(16) What is another word for "stomach flu"? - ✔✔Gastroenteritis
✔✔(16) Which bacteria causes botulism? - ✔✔Clostridium botulinum; get it from canned
food with dented, puffy, or loose lids.
✔✔(16) What bacteria causes Staphyloccal intoxication? - ✔✔Staphlococcus aureus
✔✔(16) What causes "thrush"? - ✔✔Candida albicans
✔✔(23) What is a community? - ✔✔A set of guilds
✔✔(23) Is rhizobium a free living, and nitrogen fixing bacteria? - ✔✔No
✔✔(23) Which gases are found in the atmosphere? - ✔✔Carbon dioxide, nitrogen, and
sulfur
✔✔(23) Which zone is only found in the ocean? - ✔✔Abyssal Zone
✔✔(23) Where are most marine microorganisms present? - ✔✔Littoral Zone, this is
where light is present and it's the area of the shoreline.
✔✔(23) What is a category A agent? - ✔✔Tremendous potential for adverse public
health effects. Easily transmitted from person to person, high mortality rate, require
special action for public health prepardness. Example: Bacillus anthracis (anthrax)
