BACTERIAL URINARY TRACT INFECTIONS Flashcards
Signs and symptoms
● Frequent, urgent, painful urination
○ Sometimes you feel urinating but nothing really goes out
● Urine may be cloudy with foul odor
BACTERIAL URINARY TRACT INFECTIONS (UTI)
are the most common cause of UTI
Enteric bacteria
causes most cases of UTI
Escherichia coli
Virulence factors of BACTERIAL URINARY TRACT INFECTIONS (UTI)
attachment fimbriae and flagella
that can propel the bacteria up the urinary tract
flagella
that bind specifically to epithelial cells lining the
urinary bladder
attachment fimbriae
Using fimbriae, these strains of E. coli move into bladder
cells by an unknown mechanism and form biofilm-like aggregations within bladder cells’ ? thus avoiding some of the body’s defenses
cytosol
Are the most common bacterial infection known to humans
BACTERIAL URINARY TRACT INFECTIONS (UTI)
reason why uni is common in females
1.) urethra’s short length
2.) 1/3 of women have at least had one episode of UTI
3.) Almost half of the women experience once in their
lifetime
Most common nosocomial infection
Catheter Associated UTI
how to diagnose UTI
urinalysis
bacteria cause of UTI
Uropathogenic Escherichia coli (UPEC)
Common infection in the Philippines
LEPTOSPIROSIS
Zoonotic disease seen primarily in animals
LEPTOSPIROSIS
Signs and Symptoms
● Abrupt fever, myalgia, muscle stiffness, & headache ● Rarely fatal
LEPTOSPIROSIS
bacteria of leptospirosis
Leptospira interrogans
Leptospira interrogans (gram + or -)
-
Leptospira interrogans (aerobic or non aerobic)
aerobic
Transmitted by contact with urine of infected animal or
urine-contaminated water
LEPTOSPIROSIS
travels via the bloodstream through the body
Spirochete
Occurs throughout the world but rare in the U.S.
LEPTOSPIROSIS
how to diagnose leptospirosis
antibody test
An immunological response of the kidney due to infection characterized by the sudden appearance of hematuria (blood in the urine), proteinuria, and hypertension
STREPTOCOCCAL ACUTE GLOMERULONEPHRITIS
It is actually a childhood disease that accounts for approximately 90% of renal or kidney disorders in children
STREPTOCOCCAL ACUTE GLOMERULONEPHRITIS
bacteria of STREPTOCOCCAL ACUTE GLOMERULONEPHRITIS
Group A Streptococci or Streptococcus pyogenes
Inflames the kidney nephrons / cells of the kidney and the tiny
blood vessels filtering it
glomerulus
Inflammation of the glomeruli and nephrons
glomerulonephritis
Produce hypertension and low urine output
glomerulonephritis
