ELISA
|
Enzyme-linked immunosorbent assay, testing for the presence of
antibody in the test serum directed against known pathogens. Suspect or borderline results of this
testing are submitted to an outside reference laboratory which uses a
different source of test antigen.
|
CHEM
|
Clinical chemistry
determination to detect elevations in specific enzymes or metabolites in
the bloodstream. In the case of LDHV, a significant rise in serum
lactate dehydrogenase is suggestive of persistent
LDHV infection in the absence of other clinical disease.
|
NP
|
Nasopharyngeal
culture, generally onto blood agar. Sample is collected aseptically
via tracheotomy.
|
ENT
|
Enteric culture,
generally onto MacConkey agar or other selective
media, which may include appropriate media for microaerophilic
culture of Campylobacter or helicobacter spp.. Sample is
collected by transection of the appropriate
segment of intestine.
|
ANAER
|
Enteric or
nasopharyngeal culture placed onto pre-reduced selective media and
incubated under anaerobic conditions.
|
PELAGE
|
An examination of the
fur and skin for ectoparasites and other lesions,
usually after the skin surface of the carcass has been allowed to cool.
|
TAPE
|
A microscopic
examination of cellophane tape which is impressed onto the perianal zone to detect deposited ova of Syphacia spp.
|
MICRO
|
A wet mount or stained
smear examined microscopically to detect motile organisms or protozoal cysts, respectively.
|
FECAL
|
Flotation of feces or
colon contents to detect helminth ova as well as
parasitic protozoal cysts.
|
HISTO
|
Histopathology of
target tissues to detect the presence of specific pathogens or infectious
agents, often employing special stains. If positive results are
obtained, or are suspected based on clinical signs or gross lesions, other
methods such as serology or PCR may be used as ancillary tests if
available.
|
PCR
|
Polymerase chain
reaction to amplify the target nucleic acid sequence of the infectious
organism to a detectable level.
