Q

Wohlfahrtia magnifica sp

A

Skin/wounds/natural openings of animals (genitals)
Foot sores
Ears
Close to the base of horns

17
Q

What are the agents of non-traumatic myiasis= myiasi sensu lato

A

BOTFLIES!!
Flies develop INSIDE the body, quite deep (for sure they must be underneath the skin)
The larvae develop internally- do not get in touch with the outer environment

18
Q

Botflies are also known as

A

Warble flies

19
Q

In general about botflies

A

Family: Oestridae
Parasitic
The larvae feed and grow inside the host
Adults cannot feed but can REPRODUCE

20
Q

Oestridae subfamilies

A

Cuterbrinae- skin of rodents
Hypodermatinae- tissues of Ru
Gasterophilinae- stomach of odd-toes mammals
Oestrinae- nasal sinuses of ungulates

21
Q

Subfamily: Hypodermatinae

A

Large
Resemble bumble bees
No mouth part
Maggots are white grubs with spines, turn black before they pupate in the environment

22
Q

Wandering larvae of cattle

A

Hypoderma bovis sp

Hypoderma lineatum

23
Q

Hypoderma bovis sp

A

Travels from CT– spinal canal– subcut on back

24
Q

Hypoderma lineatum

A

Travels from CT– esophagus– SC tissue of the back

25
Q

Human botfly

A

Sarcophagid

Has red eyes

26
Q

Subfamily: Gasterophilinae

A

Larvae develop in the stomach of the host
Larvae have spiracles: L1 has one spiracle and so on…
Resemble honeybees
3rd instar grubs are red and have strong spines
Eggs look similar to nits of lice BUT nits have operculum
Affects horses- prevention with Noromectin

27
Q

Gasterophilinae species

A

Gasterophilus:

  • intestinalis
  • nasalis
  • haemorhoidalis
  • pecorum
28
Q

Gasterophilus intestinalis

A

Eggs on shoulder

Development in oral cavity

29
Q

Gasterophilus nasalis

A

Eggs on lips

Development in oral cavity, pylorus, duodenum

30
Q

Gasterophilus haemorhoidalis

A

Eggs on lips

Development in oral cavity, stomach and rectum

31
Q

Gasterophilus pecorum

A

Eggs on grass

Development in oral cavity and pylorus

32
Q

Nasal botflies

A

Subfamily: Oestrinae
Ungulates
The only oestrus genus that occurs in livestock
Female lays 1st larva (3 larval stages) this develops to GRUB
Grub: banded, medium spines ventrally, feeds on mucus in nasal passages and sinuses

33
Q

Oestrus Ovis

A 
SHEEP
Greyish adults with mottled surface 
Secondary bacterial infection causes false grid:
-incoordination
-purulent ethmoiditis and encephalitis
