Attempts were made to clarify whether laboratory guineapigs may harbour a poliovirus which, in 1911, was described as the cause of a disease called guineapig lameness. By the use of ELISA for antibodies against the poliovirus, Theiler's murine encephalomyelitis virus (TMEV), it was shown that two pet shop guineapigs suffering from lameness had extremely high titres against poliovirus, while healthy guineapigs from the same pet shop were negative. Clearly positive results were also found in 35 out of 152 laboratory guineapig sera. Positive results were found in only two out of six breeding centres, but in three out of three experimental units, all of which purchased guineapigs from one of the seropositive breeding colonies. The diseased guineapigs recovered fully after treatment with vitamins in the drinking water, a treatment used for guineapig lameness by small animal practitioners. A theory that vitamin C deficient guineapigs are, due to an impaired steroid secretion, predisposed to succumbing to infection and develop demyelinating disease similar to that in TMEV infected mice is discussed briefly. Guineapig sera were also tested serologically for other infections. Antibodies against lymphocytic choriomeningitis virus, Clostridium piliforme and Toxoplasma gondii were not found, but one breeding colony was infected with adenovirus, pneumonia virus of mice, reovirus type 3, Sendai virus, parainfluenza (simian) virus type 5 and Encephalitozoon cuniculi. Two other breeding colonies were infected with both reovirus type 3 and E. cuniculi. In all three experimental units infection with adenovirus was observed, and in two of these Sendai virus and E. cuniculi antibodies were also found. The pet shop guineapigs were infected with adenovirus, reovirus type 3 and E. cuniculi.

Scorbutic guinea pigs injected with CNS and mycobacterium to induce experimental allergic encephalomyelitis (EAE) showed no clear-cut neurological signs and failed to show histological evidence of central nervous system damage. The degree of protection afforded by vitamin C deprivation was related directly to the duration of the scorbutogenic diet and inversely to the strength of the CNS challenge. Vitamin C deprivation also abolished tuberculin sensitivity as measured by the PPD skin reaction. Upon restoration of vitamin C, the animals recovered their sensitivity to PPD but did not develop EAE. It was further demonstrated that these effects of vitamin C deprivation were not related to inanition or to the endogenous levels of 17-hydroxycorticosteroids.

A myelin basic protein (MBP)-induced experimental allergic encephalomyelitis (EAE) involves paraplegia due to a reversible thoracolumbar spinal cord impairment. The aims of this study were thus to find significant metabolic biomarkers of inflammation and identify the site of inflammation in the central nervous system (CNS) during the acute signs in of the disease using metabolomics. All the EAE samples were associated with higher levels of lactate, ascorbate, glucose and amino acids, and decreased level of N-acetyl-aspartate (NAA) compared to the control group. A decreased NAA level has been particularly shown in lumbar spinal cord in relationship with the clinical signs.
