Strongyloides

The source is a sputum suggests a Strongyloides stercoralis infection. The first picture from a Gram stain shows a short stumpy rhabditiform or L1 larva with its genitalia primordium. Second picture on show its filariform stage. The third picture shows its notched tail. The last picture shows a short bucal cavity.
Right or wrong I’m still a loyal fan of this Blog.

Strongyloides- curved, pointed tail is a big clue

Strongyloides spp, we can indeed see the genital primordium so it's most likely an L1 larva.

Classic filariform larva of Stronyloides in the setting of probable Strongyloides hyperinfection - classically complicated by enteric bacterial secondary infections such as blood stream infection or meningitis.

Strongyloides. Easy question, because I'm not familiar with the other opportunities :)))) We had two patients with hypereosinophilia. Both treated with aerosols against asthma.

Strongyloides sp. larvae, probable hyperinfection syndrome given the immune suppression from the transplant and gram negative rod bacteremia.

Looks like Strongyloides stercoralis/Patrik
