Nematode
Roundworm
Lifecycle
Epidemiology
Pathology
How pathogenic should these worms be? Goal is not to kill the host..?
Morphology
Locomotion
Able to actively move towards hosts, increases incidence
Size
small worms, smaller than small strongyles
eyes
more complex eyes to be able to see and move towards the hosts. More likely to infect
large mouth
to accommodate the teeth (large bucal capsule)
sharp teeth
blood sucking, attachment
muscular
Its muscles help with locomotion, worms can move longer distances without depleting all their energy.
Sexual dimorphism
Temp sensor?
Should worms have a temperature sensor to know when a host is near? or are eyes enough?
Females larger than males
Females larger than males--hold more reproductive organs
motile larvae & adults
able to move large distances?
Other modes of transportation?
Mechanical vectors
flies/other insects?
small enough to travel through blood vessels
Adult females: 0.5cm
Adult males: 0.3cm
One-host lifecycle
Only one host needed to complete lifecycle. No need for intermediate hosts..makes them more difficult or easier to control?
high reproducibility
One female can produce 500K offspring.
Would it be worthwhile to have worms undergo parthenogenesis? Males only used for genetic diversity?
Host spectrum??
localization
Females lay eggs in intestines? have to ensure eggs are excreted somehow.
environmental stage
Eggs hatch, most conditions are okay, develop in environment until L3 infective stage? then seek out host
monoxenous, oligoxenous
can infect many host species?
Females die after producing eggs?
males die after mating?
livestock species?
wildlife species
targets mutiple organs
no preference in localization, spreads through body via blood. This allows worms to spread and replicate without running out of room (attachment places)
hypobiosis?
Worms halt in development to ensure egg survival in environment.
worldwide occurence
worms are able to tolerate many climates, even arid and cold ones?
pasture contamination?
herd problem?
easily spread in crowded operations
more common during certain seasons?
Dependent on when eggs are most viable? mild weather/warmer weather vs winter?
More of an issue in young or adult animals?
Should worms try to actively target adult animals? Less likelihood to kill/damage host..less likely to be noticed and treated?
Transmission??
Adults are bloodsuckers
Blockages/obstruction
Immunology
Host penetration?
Depending on how worms enter their host (ingestion or penetration of the skin?) Skin lesions could be present (Inflammation of the skin)
anemia in small hosts/young
lesions from attachment sites
loss of function of organ
Loss of function from high burden of worms feeding/causing lesions. Connective tissue will replace damaged organs
Range of clinical signs depending on affected organs
dependent on burden
Host immunity low or high??
Having low or no immune reaction will make worms less detectable..? Able to spread more efficiently through the host?
inflmmation of the skin??
This depending on how worms enter the host..active penetration?
