The following organism was found coming out from a AIDS-patient with a skin ulcer.
No. That organism came out from a lesion. It was inside. We were surprised about it.
I would think that is a fly larvae but can't tell, I showed an entomologist and she said it was a beetle larvae
Thanks Diana, the last, is similar answer from Daniel. This would be the yellow mealworm larval stage. Probably a case of canthariasis.
Nature has many quiz which are unsolved. As itwas coming out of the wound, it indicates that it was going to pupate..Keep an eye on the wound. Luckily you may found more fo study
Hola Javier, colega eso es una larva de escarabajo, es un estadio larvario donde no tienen desarrolladas las patas en el segmento abdominal. Lo más seguro es que se trate de la especie Tenebrio molitor, Linnaeus 1758. Que yo sepa este escarabajo sirve de hospdero intermediario para algunas parasitosis del hombre, pero no es patógeno de por sí para el hombre. Ahora no sé, si en pacientes con SIDA, que están inmucomprometidos puedan tener un comportamiento difrente.El próximo fin de semana estaré en el Quindío, cerca de Pereira, aunque sé que viajarás pronto a Ecuador para el congreso de API. Saludos y un abrazo,
Fidel Angel Núñez
Estimado Fidel.
Pereira y Armenia están super cerca, por favor, avísame apenas llegues. Me gustaría poder mostrarte mi universidad e incluso invitarte a que nos dictes una charla. ¿De cuando a cuando estarás? Avísame por favor. El congreso de Ecuador es el 15 de mayo
Is this the larva of the tumbu fly (Cordylobia anthropophaga)?
Years ago one of the patients in my St Thomas' Hospital STI clinic presented with a 'boil' on the shaft of his penis. The experienced clinical assistant examining him squeezed the spot and her screams could be heard throughout the department as this wriggling beast emerged. (the full story is found on page 116 of the 2nd edition of Sexually Transmitted Infections the Facts1).
The patient was from Africa where this form of dermal myasis is found. There have been reports from Spain and Portugal2 but this is not my speciality so my knowledge is scanty. There are similarities between yours and the OTM's picture2. Was the patient's origin or travel history of relevance?

Well David, until now, most of the people coincide it's Tenebrio molitor. I sincerely don't believe this is a larvae of any fly. Best wishes, Alfonso.
I agree with Alfonso himself, does not appear to be a fly larva, that is evident. Could be one of the rare cases of canthariasis if it was found in a skin wound! Very interesting.
Daniel as I already mentioned it was not used for that, was found accidentally involved in a skin lesion of patient with HIV/AIDS: Thanks Scott.
Yep it is a beetle larvae family Tenebrionidae or something closely related. They do not infest living tissues or even dead animals in most cases. It might be an accidental introduction or is it possible the patient put it there.
It is insect larvae, it might be an adult insect laying eggs on patien skin wound and develpment there.
It does appear to be a beetle larva. Possibly Tenebrionidae but it could be one of many families. You must get a key, and there are keys to immature insects available. Let me know if you can't find any and I can provide references.
Best wishes,
Bruce
Bruce I have not find yet a key for larvae of Tenebrionadae; do you have one?
