 ==Distribution==
 [[Myiasis Producing Flies]] are found in most regions of the world.
 ==Signalment==
 Presence of '''wounds, wet fleece''' in sheep cases, recent '''surgery''', bacterial wool/skin contamination and '''faecal contamination''' are the main predisposing factors for myiasis.
 Density of stock will determine size and viability of the fly population.
 ==Clinical Signs==
-Can be classified as '''cutaneous, nasopharyngeal, intestinal''' or '''urogenital'''.
+Can be classified as '''cutaneous, nasopharyngeal, intestinal''' or '''urogenital'''. '''Pain, irritation, discomfort, alopecia''' and '''pruritus''' are common signs locally. There is also likely to be '''direct tissue damage, haemorrhage''', hyperpigmentation and secondary infection.
-'''Pain, Irritation, Discomfort, Alopecia''' and '''Pruritus''' locally.
+[[Oestrus ovis |'''Nasal myiasis''']] causes irritation and [[Epistaxis |epistaxis]].
 '''Aural myiasis''' can cause deafness, discharge and foul exudates.
-[[Gasterophilus spp. | '''Gastrointestinal myiasis''']] often causes '''ulceration, GI bleeding''', weight loss, [[Diarrhoea | diarrhoea]] and pupae are voided in faeces.

 '''Loss of feathers''' and soiling of the vent is seen in '''poultry'''.

+In severe cases, anaemia, anaphylaxis and toxaemia may be fatal. Likely consequence is reduced feeding and resulting weight loss and infertility.
