31. The HP virus is classified in the Rhabdoviridae family and is related to the viral agents that cause vesicular stomatitis . 32. This rabies relative, called vesicular stomatitis virus ( VSV ), is a cattle virus and not lethal to humans. 33. The stomatitis symptoms are similar to those seen in pellagra, which is caused by niacin ( B 3 ) deficiency. 34. Malaise, fever and / or cervical lymph node enlargement are rare ( unlike the typical features of herpetic stomatitis ). 35. Persons with aphthous stomatitis have no detectable systemic symptoms or signs ( i . e ., outside the mouth ). 36. Some people with aphthous stomatitis may show herpes virus within the epithelium of the mucosa, but without any productive infection. 37. Apart from not being restricted to the tongue, migratory stomatitis is an identical condition in every regard to geographic tongue. 38. Differential diagnosis is with other causes of oral ulceration such as aphthous stomatitis , secondary herpetic lesions, syphilis, etc. 39. Transmission to vertebrates usually occurs via a tick tick-borne encephalitis, vesicular stomatitis virus and West Nile virus viruses. 40. This has led some to conclude that the defining feature of a true infection is absent in denture-related stomatitis .
