| Question |
Answer |
| Diarrhea in neonates. K88: swine; K99: cattle |
Enterotoxic E. coli |
| Do not invade tissue; heat labile or stable; exotoxins are absorbed => more cAMP => more water and Cl- secretion |
ETEC |
| cause septicemia and bacteremia in neonatal animals. |
enteroinvasive E. coli (EIEC |
| Penetrate epithelium, endotoxins cause damage. |
Enteroinvasive E. coli |
| Edema disease in pigs. O157:H7 in greyhounds and humans (Hemolytic uremia) |
Enterohemorrhagic E. coli |
| Attach to microvilli and cause effacement or destruction; NOT invasive. (NO enterotoxins) |
Enteropathogenic E. coli |
| a short gram-negative rod with petritrouchous flagella. |
Escherichia coli |
| It is motile and non spore-forming and ferments lactose and glucose. |
Escherichia coli |
| gives E. coli a metallic green appearance. |
EMB agar |
| Somatic/Lipopolysaccharide |
O |
| Flagella |
H |
| Capsular |
K |
| Pili/Fimbrae |
F |
| almost always associated with pigs. |
K88 (also called F4) and 987p (also called F6) |
| Diarrhea in calves is often caused by |
K99 |
| All enterotoxins are |
exotoxins. |
| The virulence factors of enterotoxic E. coli are |
exotoxins and pili antigens |
| The exotoxins are absorbed into |
the epithelial cells. |
| cause effacement or degeneration of microvili without entering the cell. |
Enteropathogenic E. |
| cause septicemia and bacteremia in neonatal animals. |
enteroinvasive E. coli |
| Acute colisepticemia usually does NOT cause |
diarrhea or fever |
| Bovine mastitis caused by E. coli rapidly reduces |
milk production |
| causes 70% of pyometra cases in bitches. |
Escherichia coli |
| Pigs are quite susceptible to what until they are about 14 weeks old. |
E coli |
| Post-weaning colibacillosis in pigs is almost always caused by |
K88 |
| Edema disease in pigs is caused by |
EHEC or VTEC |
| The symptoms are muscle tremors, staggering gait, facial edema (especially eyelids) and posterior paralysis before death. |
Edema disease |
| Birds of any age can get acute septicemia caused by. |
E coli |
| Arthritis may develop in poultry after |
septicemic infection |
| can cause E. coli poisoning in humans. |
Raw hamburgers |
| Hemolytic uremia syndrome in humans is caused by |
O157:H7 |
| Greyhounds can get “Alabama rot” which is caused by |
E. coli O:157:H7 |
| Bacteremia in humans is occasionally caused by |
Enterobacter cloacae |
| Mastitis can be caused by |
Enterobacter aerogenes |
| is normally found in the soil |
Citrobacter |
| has a large capsule, is not hemolytic and can cause mastitis in cattle, cervicitis and metritis in mares, and urinary tract infections. |
Klebsiella |
| does not ferment lactose, is highly motile and non-hemolytic |
Proteus |
| frequently causes urinary tract infections in cats and dogs. |
Proteus |
| causes bubonic plague. |
Yersenia pestus |
| Salmonella Typhiurium |
No host preference |
| Salmonella Choleraesuis |
pigs |
| Salmonella Pullorum |
poultry |
| Salmonella Gallinarum |
poultry |
| Salmonella Enteritidis |
No host preference |
| Salmonella Dublin |
cattle and humans |
| Salmonella Typhi |
Humans |
| describes salmonella infections caused by non-host-adapted serotypes. |
Paratyphoid |
| of flagellar antigen is referred to as |
H-O variation |
| The differences in capsule thickness (quantitative antigenic changes involving Vi antigens) are called |
V-W variants |
| A strain changes from smooth to rough (S-R variation) when the is gradually lost to expose the core polysaccharide. |
O antigen |
| is destroyed by boiling. |
flagellar antigen |
| Typhoid fever is caused by |
human-adapted serovar |
| are non-motile and paratyphoids are motile |
Pullorum and Gallinarum |
| causes bacillary white diarrhea in poultry |
Salmonella Pullorum |
| Fowl typhoid is caused by |
Salmonella Gallinarum |
| Organism identification is the only way to distinguish fowl typhoid from |
pullorum |
| produces green diarrhea and the wattles and combs have a purple discoloration. |
Fowl typhoid |
| is usually caused by Salmonella Dublin and Salmonella Typhimurium |
Bovine salmonellosis |
| Calves 2-6 weeks are most susceptible |
Salmonella Typhimurium |
| is more likely to produce the carrier state in cattle |
Salmonella Dublin |
| Cattle with what have fever, diarrhea (brown or green, sometimes bloody) and sometimes get arthritis, pneumonia, or encephalitis. |
salmonellosis |
| is the most common serovar in pigs. |
Salmonella Choleraesuis |
| are often carriers of salmonella |
