is the presence of bacteria in the bloodstream.

also called infectious waste or biomedical waste, is any waste containing infectious materials or potentially infectious substances such as blood.

the application of safety precautions that reduce a laboratorian's risk of exposure to a potentially infectious microbe and limit contamination of the work environment and, ultimately, the community.

Umbrella term for bacteria that has originated from the GI tract. This is most commonly E. coli.

a bacterial cell or cluster of cells that give rise to a colony on a plate.

Complete Metamorphosis: Involves a radical transformation between stages (egg → larva → pupa → adult).

Contagious mastitis is the “cow-associated” form where infected cows are the reservoirs for bacteria and spread occurs cow to cow at milking time

inflammation of the urinary bladder.

large family of Gram-negative bacteria that includes E. coli.

This is a type of development in which the immature stage (nymph) is a smaller version of the adult.

an erythrocyte inclusion from denatured hemoglobin

the presence of blood in urine.

capable of living solely on or in one species of host.

Incomplete Metamorphosis: Involves gradual growth without significant change in form (egg → nymph → adult).

An immature erythrocyte just prior to development to a polychromatophil. This stage still has a nucleus. Also known as a nucleated red blood cell.

is a supervital stain that is used in veterinary medicine to stain residual ribosomal RNA (reticulin) or Heinz bodies

characterized by painful, frequent urination of small volumes that are expelled slowly only by straining and despite a severe sense of urgency, usually with the residual feeling of incomplete emptying.

Tamm-Horsfall protein (THP) is exclusively produced by renal tubular cells of the distal loop of Henle and is the most abundant urinary protein in mammals.
