Infected, yes. Infectious, maybe.
Yes, if they bite hard it tends to bruise rather than break the skin though. However, they very rarely bite hard, sometimes they like to nibble your fingers in the same way they clean another chinchilla.
Insects often inject an irritant or poison to make their bite hurt, but if not the bite itself can hurt if it breaks the skin.
Immediately or without delay
no ive never known guinea pigs bite
Anything that breaks skin can be infectious. Being from mouth and it being a farm animal wouldn't be surprising if you left it untreated it got infected. They eat grass and hay whether they be in a field or a stall. They walk in mud, feces, urine and I doubt they get their mouth cleaned. Clean your bite wound and watch it. If it gets red, inflamed, puss where the dead skin is get to the doctors asap. If left untreated it can result in loss of limb and if it hits the blood stream, your life.
You can get rabies and other bacterial diseases from a dog bite, but not things like "parasites" such as worms.
A bite is an injury caused by an animal, such as a mammal or insect, that breaks the skin. A sting is a puncture wound made by insects or marine animals.
A chinchilla is a cute, furry animal. They are covered in skin and by a fluffy coat of fur that often needs to be covered in talc powder.
Yes but you can't really feel the bite on the skin
Impetigo.
Only female Mosquitoes bite and perice the skin causing you to itch.
When a fracture breaks the skin, it is a compound fracture or open fracture. Because the skin is broken, there is a possibility of infection.
