A paracolon infection is a bacterial infection that chickens can get. There are different types of bacteria, some good, some bad. Paracolon infection is from bad bacteria and  can be caused or spread by the following means:
An infected hen
Infected chick
Spread in an incubator
Spread in chick boxes
Can spread in brooder houses
Can be transmitted from shoes or equipment
Contaminated premises: If one coop is infected and you go to another coop that is not infected it can become infected easily. If you have infected birds and even if your birds have recovered, you should not visit other places where chickens are raised as the infection can spread on vehicle tires, shoes, clothing, etc.
Carrier birds which shed infected organisms: Survivors of a paracolon infection even though they may appear healthy can still get other birds sick and should not be kept with the flock or allowed to breed.
​Symptoms of paracolon infection are:

• Lesions

A group of paracolon organisms are defined in a group called Arizona pracolons and have several characteristics that are the same or close to paratyphoids and coliforms, so it is advisable to get a vet that specializes in poultry care to examine and do bacterial testing to eliminate possible misdiagnosis, "They can be differentiated from the paratyphoids by their biochemical reactions but but the similarity between groups causes some delay and confusion in correct identification. These organisms are distributed widely in nature and have a host range which coincides with Salmonella." According to Berry, Joe, G. poultry specialist and Delbert Whitenack
Pathologist, Veterinary Medicine   
Transmission prevention and treatment depends entirely on careful lab exams, isolating the infected birds to identify possible causes.
