Antibiotics Drug Flashcards
Bacteria
Also known as prokaryotes which are single-celled organisms that lack a true nucleus and nuclear membrane
Anti-Bacterial Drugs
Substances that inhibit bacterial growth or kill
bacteria and other microorganisms
Empiric Therapy
when a drug selected is known to be the best drug that can kill the MO
Definitive Therapy
once the MO is identified in the lab, the antibiotic therapy is tailored by using the most narrow-spectrum, least toxic drug based on C&S results
Superinfection
occurs when the antibiotics reduce or completely eliminate the normal bacterial flora
Stage 1 of HIV Infection
asymptomatic infection (Few weeks to months after exposure)
Stage 2 of HIV Infection
early, general symptoms of disease (lymphadenopathy with fever, rash, sore throat, night sweats, candidiasis. Patient is termed HIV positive. May still be able to seroconvert .CD4 cells begin to drop
Stage 3 of HIV Infection
moderate symptoms – infection progresses, and opportunistic infection begins
Stage 4 of HIV Infection
severe symptoms, often leading to death – increasing destruction of helper T cells, decline in immune function. When CD4 drops to 200 cells/mm3 below, severe opportunistic infections and other system symptoms appear.
How many stages of HIV infection are there?
4
What is HIV?
is a retrovirus which attaches to a host cell in order to replicate
What are Anti-Helminthic Drugs?
are very specific with the worms they can kill thus accurate identification of causative organisms prior to treatment is necessary
What are Helminths?
are large and complex multicellular structures
What is the most antimalarial drug for eradicating the parasite during the exoerythrocytic phase?
PRIMAQUINE
It is characterized by granulomas in the lungs from accumulation of inflammatory cells with a cheese-cased consistency
TUBERCULOSIS
