==Good worm vs Bad worm==
=Parasitic Worm Infections in Rabbits=
Its like only 4 worms exist . And if its white its bad . And red is a good .. but there is like thousands of worms  Not All worms are bad.


==Good Worms==
==Passalurus ambiguus (Pinworm)==


===Etiology (cause)===
Passalurus ambiguus is the most common nematode in domestic rabbits. Transmission occurs via ingestion of infective eggs shed in feces.

*Were they found IN THE RABBIT , or IN THE COMPOST?
===Clinical Signs===
*Are the rabbits showing any signs of hair it weight loss? Itchy butts? If not . Probably not a pin worm.
- Often asymptomatic in light infections 
*Have you butchered recently? They will be obvious in the intestines... if not .. its NOT a pin worm.
- Heavy infections: perianal irritation, scratching, reduced growth rates, occasionally diarrhea 
*Are your rabbits in cages? Probably NOT A PIN WORM.

===Treatment, Prevention, and Control===
pin worms wouldn't just be falling out of your rabbit for you to see unless the rabbits were given a dewormer that stunned the pin worms and caused them to fall out. Even then, they would be encased inside the poop. You would have to break apart the poops to free the pin worms in order to take this pic.
- Fenbendazole (20 mg/kg orally for 5 days) is effective 
- Pyrantel pamoate is an alternative treatment 
- Strict cage hygiene and removal of fecal material to reduce reinfection

Reference: 
rabbits can't give humans pinworms, nor can humans give rabbits pinworms. I mean, I suppose technically, some rabbit pinworm somewhere could mutate enough to be able to infect a human and become the subject of scientific literature around the world, but my non PhD self says that seems unlikely.

Syphacia muris is zoonotic and commonly found in humans. Caged rabbits dont just get pinworm. I'd be concerned rodents are in or around the rabbit feed or cages.
