Adenovirus 40/41

Adenovirus 40/41 refers to two enteric adenovirus types that can be detected in stool. These viruses are not considered a normal part of the dog’s gut microbiome. A finding may reflect exposure through faecally contaminated water, food, surfaces, or shared environments. Adenovirus 40/41 is mainly linked to the gastrointestinal tract, where enteric viruses can be associated with diarrhoea, vomiting, altered stool quality, reduced appetite, low energy, or signs of gut irritation. Because Adenovirus 40/41 is primarily known as a human enteric adenovirus group, a finding in a dog sample should be interpreted carefully. A positive finding may be useful to review with a veterinarian, especially if digestive signs are present or if there are hygiene concerns in a shared environment.
