immune system
• colitis occurs in mice as they age (4 months and over)
• disease resembles the human disease ulcerative colitis
• T cells in the thymus do not pass the double positive stage
• very few T cells are found in the thymus or periphery
• very few CD8 T cells are found in the thymus or periphery
• numbers are markedly increased
• mice do not produce IgG following infection, although M. pulmonis-specific IgM antibodies are detected
• airway vascular and airway lymphatic vessel remodeling are impaired or absent compared to wild-type mice after M. pulmonis infection

respiratory system
• M. pulmonis infected mice show a diminished or intermediate airway remodeling phenotype when compared to wild-type or Igh-6 deficient mice

hematopoietic system
• T cells in the thymus do not pass the double positive stage
• very few T cells are found in the thymus or periphery
• very few CD8 T cells are found in the thymus or periphery
• numbers are markedly increased
• mice do not produce IgG following infection, although M. pulmonis-specific IgM antibodies are detected

digestive/alimentary system
• pronounced depletion of goblet cells resulting from inflammation
• is observed in older mice
• caused by neutrophil infiltration
• occurs in rare cases
• occurs in mice over 4 months of age
• colitis occurs in mice as they age (4 months and over)
• disease resembles the human disease ulcerative colitis

endocrine/exocrine glands
• caused by neutrophil infiltration

mortality/aging
• mortality rates increase after six months of age
• few mice survive longer than one year

cellular
• pronounced depletion of goblet cells resulting from inflammation
