title: Plasmodium chabaudi chabaudi chronic malaria and pathologies of the urogenital tract in male and female BALB/c mice.
abstract: BALB/c mice of both sexes were infected with a non-virulent strain of Plasmodium chabaudi chabaudi and any pathologies occurring in the urogenital tract and its accessory glands were investigated. Organs and tracts were removed from infected and control mice at 15, 40 and 100 days post-injection, weighed and processed for macroscopical and histological analyses. The relative weights of preputial, clitoral glands and testes were modified in infected mice during the 40 days following infection. The preputial glands show a marked hypotrophy at 15 days post-infection. The bladders of half of the infected female mice and a few infected male mice displayed a conspicuous haemoglobinuria and frequent interstitial cystitis that worsened throughout the experiment. Also, several chronic inflammatory reactions were detected in the prostates, preputial and clitoral glands up to 100 days post-infection. A probable cause of such a divergence in the characteristics of the infection and in the nature of the pathologies identified in infected male and female mice is the interaction between the infection and the immune and endocrine systems of the host. The cause of the pathologies and their consequences on the host condition are discussed.
