Coxsackievirus infection in mice

Area of Science:

• Virology
• Endocrinology
• Pathology

Background:

• Coxsackie B viruses are known to cause various human diseases.
• Viral infections can sometimes lead to metabolic disturbances, including diabetes.
• The long-term effects of coxsackie B virus on pancreatic function require further investigation.

Purpose of the Study:

• To investigate the effects of coxsackie B1 and B4 virus infection on white mice.
• To assess viral persistence, antibody response, and histological changes in infected mice.
• To evaluate glucose tolerance and potential development of diabetes following viral inoculation.

Main Methods:

• Infection of NYA:NYLAR mice with coxsackie B1 or B4 virus.
• Monitoring viral persistence and antibody conversion over 13 months.
• Histological examination of pancreatic tissue.
• Assessment of glucose tolerance at various time points post-infection.

Main Results:

• Pancreatitis was observed during the acute phase of infection.
• Evidence of subclinical diabetes was detected within the first six months.
• Glucose tolerance normalized in mice between 10 and 13 months post-infection.

Conclusions:

• Coxsackie B virus infection can induce temporary pancreatitis and subclinical diabetes in mice.
• The observed functional pancreatic lesion appears to be reversible.
• These findings suggest that coxsackie B virus may play a role in transient metabolic dysfunction.
