Extra worms

Question 1

Eucoleus bohmi

Answer 1

• Nasal Capillariasis

in sinus mucosa of the fox and dogs

Question 2

Eucoleus aerophilus

Answer 2

• Bronchial Capillariasis
in dogs, cats (rarely pathogenic), and foxes (pathogenic; bronchopneumonia); earthworm is a facultative intermediate host; diagnosed by eggs in feces or tracheal mucus

Question 3

Aonchotheca putorii

Answer 3

• Intestinal Capillariasis
in the small intestine of bears, raccoons, swine, bobcats, and sometimes domestic cats. Not very pathogenic. Diagnostic problem in cats (eggs look like those of other capillarids

Question 4

Calodium hepaticum

Answer 4

• Hepatic Capillariasis
in livers of rodents and wide range of occasional hosts (humans). Eggs are trapped in hepatic tissue (remain without further development until the host is eaten or dies, when they develop into L1infective

Question 5

Personema plica

Answer 5

Urinary Capillariasis
in the mucous membrane of the urinary bladder in dogs, cats, foxes, and wolves. Eggs contain one cell when passed in the ………L1 develop in a month to hatch inside earthworm (paratenic). Definitive host eats earthworm,

Question 6

Acanthocephala

Answer 6

Vertebrate digestive tract. Flattened
Laid eggs contain fully developed larva (acanthor; see figure). If ingested by suitable arthropod develops through acanthella stage into encysted infective larva (cystacanth) capable of re-encysting in many vertebrate paratenic hosts (ingestion of infected arthropod).

Question 7

▪ Macracanthorhynchus hirudinaceus

Answer 7

Small intestine of swine

. Cystacanth infective for pigs develops in beetles

Question 8

▪ Macracanthorhynchus ingens

Answer 8

in raccoon; millipedes as intermediate hosts (dogs infection occur!)*

Cystacanth (infective)

Question 9

▪ Prosthenorchis spp

Answer 9

Cockroaches and beetles as intermediate hosts. Causes chronic (watery diarrhea for several months) and acute disease (bacterial peritonitis as result of intestinal wall perforation). Fenbendazole

Question 10

▪ Moniliformis:

Answer 10

; pseudo-segmentation of the body (confusion with tapeworm); wild rodents; cockroaches as intermediate hosts

Question 11

Hirudinea:

Answer 11

Leeches; predatory or parasitic worms
bloodsucking species attach to oropharyngeal mucus membrane and pierce the epidermis to suck blood. Salivary enzyme (hirudin) acts as anticoagulant.

Question 12

• Detection of parasite antigen in feces: ELISA

Answer 12

Giardia and Cryptosporidium in human. Used to differentiate between eggs of Echinococcus and Taenia in dogs

Question 13

• Polymerase Chain Reaction (PCR):

Answer 13

protozoa

Question 14

• Flotation Concentration of Eggs and Cysts

Answer 14

nematode and cestode eggs and protozoan cysts

Question 15

• Fecal Sedimentation Techniques

Answer 15

trematode

Question 16

• Baermann Technique

Answer 16

: Used for concentration of Nematode larvae

Question 17

• Amprolium.

Answer 17

Amprolium competitively inhibits thiamine utilization by the parasite. The drug may suppress the sexual stages and sporulation of the oocysts. Therapeutic uses: The only drug approved for both prevention and treatment of outbreaks of coccidosis in cattle (E. bovis) and poultry
