    arthrospores

    very primitive spore type, formed by the breaking up or disarticulation of fungal mycelia

    bacteremia

    is the presence of bacteria in the bloodstream.

    Biohazardous waste

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

    biosafety

    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.

    coliforms

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

    colony-forming unit (CFU)

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

    Complete Metamorphosis

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

    contagious mastitis

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

    cystitis

    inflammation of the urinary bladder.

    Enterobacteriaceae

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

    environmental mastitis

    Mastitis pathogens that are found outside the milking parlour. Environmental organisms are found in bedding, soil, walkways, on pasture or any surface with which the cow or her manure comes in contact.

    gradual metamorphosis

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

    Heinz body

    an erythrocyte inclusion from denatured hemoglobin

    hematuria

    the presence of blood in urine.

    host-specific

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

    Incomplete Metamorphosis

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

    metarubricyte

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

    new methylene blue stain

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

    pollakiuria

    means frequent, abnormal urination during the day.

    pseudoparasite

    an object or organism that resembles or is mistaken for a parasite.

    Pyelonephritis

    Upper urinary tract infection that often involves the kidneys.

    pyuria

    an abnormal increase in WBCs in the urine.

    questers

    or "quest", is the act of a tick seeking out a blood meal.

    spurious

    an incidental finding. An example of a spurious parasite is finding rabbit coccidia in a dog fecal exam.

    stranguria

    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 Mucoprotein

    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.

    turbidity

    (of a liquid) cloudy, opaque, or thick with suspended matter.

    Urine Specific Gravity

    laboratory test that shows the concentration of all chemical particles in the urine.
