Canine herpes virus is an enveloped virus, which can be transmitted by transplacental, venereal (semen, vaginal secretions) and oro-nasal routes.
It is therefore a sexually transmitted disease.
Abortion products (fetuses, fetal envelopes) can also be contaminants.
Puberty corresponds to the age of onset of first heat in a female and the production of first ejaculas in a male
It is a highly contagious haemorrhagic gastroenteritis, with systemic repercussions, caused by canine parvovirus type 2 (CPV-2), a naked virus that is highly resistant in the environment (several months).
From the wild virus CPV-2, 3 subtypes are now isolated: CPV 2a, 2b and 2c.
Contamination is carried out by the fecal-oral route.
It is a highly contagious respiratory disease, frequently encountered in dogs, especially young dogs, with significant morbidity but low mortality.
The main etiological agents involved are: Bordetella bronchiseptica, canine parainfluenza virus, canine adenovirus type 2 (CAV-2), canine herpesvirus, and canine reovirus.
Transmission is mainly through aerosols. This is not an unacceptable defect.
It is a severe gastroenteritis, highly contagious, often fatal, associated with marked leukopenia.
Disease caused by feline parvovirus (FPV), a naked virus that is highly resistant in the environment (several months).
Contamination is carried out orally and nasally.
The virus has a high tropism for cells with high replication (enterocytes, bone marrow cells, lymphoid organ cells): it causes cell necrosis by apoptosis, and therefore severe diarrhea, leucopenia and lymphoid depletion.
