Myiasis caused by E. tenax:
✔️rare but have been
✔️reported from various countries including Europe
✔️most often intestinal myiasis, but cases of infestation of the nasal cavity, urinary tract, and vagina have been described.

Fieldwork- I’ll cover some of my work into the causes of unexplained lamb losses. During 2021 and 2022 I followed lamb health issues on two farms, a croft and @SRUC’s Auchtertyre farm, which have all experienced blackloss. This gave me 12 flocks to study across the holdings. 1/17 Image
I visited the farms and croft when they were gathering their flocks in for checks and treatments at scanning, pre-lambing, marking, clipping and weaning. Most flocks lamb on the open hill, and so marking would be the first lamb check. 2/17 ImageImageImage
I assessed the lambs for any health issues to gauge what pressures and threats are present in each flock. Lambs were checked for ticks, dirty rears, and infections. Lambs with plochteach/yellowses were scored on the severity of their photosynthesisation and treated. 3/17 ImageImageImageImage

A 49-YO man “looking through branches in a tree.”: decreased vision in his L eye.

Fundus: linear and arcuate disturbances in the retina (A).

What´s in the vitreous?!! (B)

DOI: 10.1056/NEJMicm075735
#parasitology #OJO #Ophthalmology Image
A fly larva was initially observed in the macula and after 4 days of treatment with thiabendazole, a segmented fly larva in the vitreous (B).


#oftalmologia #parasites #eye Image
The patient elected to undergo vitrectomy.
Eight weeks after the vitrectomy, the lesions in the retina were attenuated and the visual acuity had improved to 20/40.

It is now 60 days until (& including) the 1st of April, 2022! April '22 marks 𝟲𝟬 𝘆𝗲𝗮𝗿𝘀 since the British Socety for Parasitology was formed from the Parasitological Section of the Institute for Biology!
To mark this, we will be releasing a #parasite breakthough/fact (1/1)
.. every day for the next 60 days: from 1962 to 2022! We will provide information on both well-studied & unusual parasites such as Angiostrongylus cantonensis, Echinococcus vogeli, Plasmodium falciparum, Mansonella spp., Hirudo medicinalis (leeches) bed bugs, & more! (2/2).
Today, we begin with 1962! Not only was the @BSPparasitology founded in 1962, but for the first time, the full life cycle of the "eye worm" Thelazia callipaeda was described by D.P. Kozlov in the Proceedings of the USSR Academy of Sciences. Human thelaziasis is an NTD. #parasite Image
