Rat-Bite fever is a rare disease caused by a bacterium called Streptobacillus moniliformis. This bacterium is found worldwide. However, in Asia, the bacterium Spirillum minus also causes Rat-Bite fever. 50-100 % of wild rats carry this disease.
They can (indirectly) if they are infected with a disease that can be transmitted to humans. Rats may carry a disease or plague that will make you sick and could kill you. It's best not to stay too close to street rats.
They will sniff each other but not for disease.

A rat bite causes an injury but not necessarily a disease. Since there are germs that live in the mouth of a rat (much as there are germs that live in the mouths of people) a rat bite can cause an infection which potentially, if not treated, can become very serious, the most extreme form of which is gangrene. It is also true that rats, like all mammals, have the capability of carrying the very serious disease of rabies. However, most rats are not rabid.

Yes you can get rabies from a WILD rat.But PET rats do not carry rabies because at the pet store, they receive rabies shots before they are put on sale.This is why you should never touch a wild rat if you ever encounter one. If you somehow get bit by a wild rat seek immediate medical attention as in going to the hospital to get a rabies shot. If a PET rat bites you do not worry because they WILL NOT carry this disease.
only if the toad had the disease then yes but all animals and bugs can carry diseases depending on the circumstances
Ratitus is a disease associated with Rats.
