Glossary
fulminating disease results and the intestinal
symptoms (nausea, vomiting, diarrhea) mimic
those seen in malignant infections—the other
name for this form of malaria is malignant
tertian malaria. As the disease progresses,
kidney involvement occurs—hence, the name
black water fever.
blepharoplast Basal body structure in hemoflagellates
from which an axoneme arises.
bradyzoites (pl., bradyzoites) Slowly multiplying
trophozoite stage of Toxoplasma gondii.
brood capsule (pl., brood capsules) Structure
inside a daughter cyst that houses developing
scolices.
buccal capsule Oral cavity of adult roundworms;
also known as the buccal cavity.
buccal cavity Oral cavity of adult roundworms;
also known as the buccal capsule.
Calabar swelling Swelling of subcutaneous tissues
that is transient in nature; occurs with infections
of the filarial parasite Loa loa.
capitulum Umbrella term referring to the mouth
parts of ticks and mites.
cardiomegaly An enlargement of the heart.
carrier (pl., carriers) Parasite-harboring host that
is not exhibiting any clinical symptoms but is
capable of shedding the parasite and infecting
others.
cercaria (pl., cercarie) Final stage of fluke development
occurring in the first intermediate host
(snail); possesses a body and a tail, which allow
the organism to become mobile.
cestoda Referning to the cestodes (tapeworms).
cestode (pl., cestodes) Alternate name for
members in the class of helminths known as
Cestoda; common name is tapeworm. In this
group of parasites, each adult worm consists of
a flat, ribbon-like, segmented body that resembles
a tape measure.
Chagas’ disease A common name for the disease
caused by Trypanosoma cruzi.
chagoma Primary lesion at the site of Trypanosoma
cruzi infection; it is an acute inflammatory
response that results in blocking of the lymphatics
and production of erythema.
chancre Local inflammation leading to painful
ulceration at the site of an insect bite.
chiclero ulcer A form of cutaneous leishmaniasis
caused by Leishmania mexicana; it is
commonly found in Belize, Guatemala, and
the Yucatan peninsula in areas in which
chicle sap is harvested for use in making
chewing gum.
chitin Nitrogen-containing polysaccharide coating;
also referred to as a shell; commonly seen on
Ascaris eggs.
chitinized exoskeleton Structure on the outside
of the arthropod body composed of an insoluble
polysaccharide providing support for internal
organs.
chromatoid bar (pl., bars) Rod-shaped structures
in the cytoplasm of some amebic cysts that
contain condensed RNA material.
cilia Hairlike projections present on Balantidium
coli trophozoites that function as the means of
locomotion.
ciliate (pl., ciliates) Common name for a parasite
that moves by means of cilia (scientific name,
class Kinetofragminophorea).
coccidia Group of protozoal parasites in which
asexual replication occurs outside a human
host and sexual replication occurs inside a
human host.
commensal Relating to commensalism; the association
between two different organisms in
which one benefits and has a neutral effect on
the other.
commensalism Association of two different
species of organisms that is beneficial to one
member and neutral to the other.
concentrated iodine wet preparation (pl., preparations)
Slide made by placing a drop of
Lugol’s or D’Antoni’s iodine on a glass slide (a
3- × 2-inch size is suggested) and mixing with a
small portion of specimen after a debris removal
process using a wooden applicator stick or
another mixing tool. The resulting slide should
be thin enough for newspaper print to be read
through the smear. A 22-mm 2 cover slip is placed
on the slide and the preparation is examined
microscopically in a systematic fashion.
concentrated saline wet preparation (pl., preparations)
Slide made by placing a drop of
0.85% saline on a glass slide (a 3- × 2-inch size
is suggested) and mixing with a small portion of
specimen after a debris removal process using a
wooden applicator stick or another mixing tool.
The resulting slide should be thin enough for
newspaper print to be read through the smear.
A 22-mm 2 cover slip is placed on the slide and
the preparation is examined microscopically in
a systematic fashion.
