Patho chap 10

infectious diseases

QuestionAnswer
host human or animal invaded and colonized by pathogen (bacteria, fungi, virus)
pathogen microorganisms capable of causing infectious disease (describes what it is)
colonization pathogen living in host (evidence of it's presence)
infection invasion, colonization, and multiplication of pathogens
virulence ability to produce disease
reservoir pathogen source ( ex - person or inanimate object)
vector living being that can carry pathogen from reservoir to host (ex - mosquito, tick)
microbial flora normal flora - organisms that live in or on the human body -> help secrete nutrients and competitively inhibit harmful pathogens
most common clinical microbiology stain is gram stain
purple gram stain indicates gram positive
pink gram stain indicates gram negative
gram positive bacterium is part of normal flora and is resistant to antibiotics staphylococcal
rhinovirus common cold and gradual onset : caused by direct or droplet transmission
influenza caused by influenza and abrupt onset of symptoms -> annual outbreaks, high mutation rate leads to seasonal vaccine
example of fungal infections candida albicans --> thrust: oropharyngeal candidiasis --> vulvaginal candidasis
what are examples of heleminths worms that cause infection
what are examples of prions proteinaceous infection agents --> brain disease: causes the brain to fold abnormally and get a sponge like appearance
primary host of taxoplasmosis taxoplasma gondi protozoan
transmission of taxoplasmosis raw/ uncooked meat and cat feces
risked patients of taxoplasmosis immunocompromised people
skin as a natural barrier to protect us from illness and how it's also a portal of entry natural barrier due to it thickness & pH - can be a portal of entry through cuts & scraps
respiratory tract as a natural barrier to protect us from illness and how it's also a portal of entry cilia, mucous secretions, specialized immune WBCs help reduce infection - mouth carry so much bacteria even through talking
GI tract as a natural barrier to protect us from illness and how it's also a portal of entry stomach pH, mucous, normal flora prevent infection - portal of entry through contaminated food or drink
GU tract as a natural barrier to protect us from illness and how it's also a portal of entry flow of urine, low pH of vagina prevent infections -- urethra is most common route; semen nad vaginal secretions can secrete infectious agents
blood blood transmission through blood transfusions, sharing of needles, mucous membranes, eyes
maternal - fetal transmission cross through placental barrier ; some through infection
1st stage of infection incubation - microorganisms replicated without identifiable symptoms: short as 24 hours or 2-3 months
2nd stage of infection prodromal - initial symptoms appear, often vague and general
3rd stage of infection acute - full infectious disease sign and symptoms are present and immune system is fully engaged
4th stage of infection convalescent - body containing the infection and progressively eliminating the pathogen and it can take days, weeks, or months
5th stage of infection resolution - pathogen eliminated from the body
hepatitis A not chronic, can be treated but highly contagious, fecal oral transmission and has to do with the liver
hepatitis B chronic HBV, can get it by blood or sexual
hepatitis C acute infection usually mild, most develop chronic hepatitis, transmitted by blood and targets the liver and B lymphocytes
hepatitis D defective RNA virus, requires helper function of HBV, and transmitted through IV drug use or sex
hepatitis E similar to HAV, and transmitted through fecal oral contamination
general signs and symptoms of hepatitis fever, malaise, myalgias, pruritus, anorexia, loss of taste for food, hematompegaly, stool have pale appearance, dark urine
