Normally, these animals didn't present any clear indications of plague, but even further bacteriological Evaluation showed which the lesions contained plague bacillus, a situation the ACPII termed Continual plague (Advisory Committee, 1906, 1907a). gandacii domnului The ACPII argued that chronic plague could demonstrate the seasonality with the disease in aspects of India. As the ACPII noted, whereas plague afflicted rats all calendar year round in Bombay, in the Punjab, However, it seemed to vanish from these animals until eventually the following epizootic.
