Cestode infection in 2 dogs: cytologic findings in liver and a mesenteric lymph node

Mesocestoides cestode infections in dogs are well known for causing severe peritonitis with larvae or larval fragments (metacestodes, tetrathyridia, or calcareous corpuscles) frequently observed cytologically in peritoneal fluid samples. This case report describes the cytologic and clinical features of 2 dogs infected with cestode larvae, with one case confirmed and the other presumed to be Mesocestoides sp. In these 2 unusual cases, cestode larvae or larval fragments were found in fine‐needle aspirates of the liver and a mesenteric lymph node, but no organisms were found in peritoneal fluid samples. The data presented in this report indicate that clinical pathologists should not rule out Mesocestoides sp cestodiasis based on the absence of larvae in peritoneal fluid samples from dogs.

Poverty impacts of foot-and-mouth disease and the poverty reduction implications of its control

Foot-and-mouth disease (FMD) remains one of the most important livestock diseases of the world, given its highly infectious nature, its broad economic impacts on animal wellbeing and productivity, and its implications for successful access to domestic and export markets for livestock and products. The impacts of the disease vary markedly between developed and developing countries, and also within many developing countries. These differences in impact shape some markedly heterogeneous incentives for FMD control and eradication, which become of particular importance when setting priorities for poverty reduction in developing countries. Some consider that the benefits from FMD control accrue only to the better off in such societies and, as such, may not be a priority for investments targeted at poverty reduction. But is that view justified? Others see the control of FMD as a major development opportunity in a globalised environment. In this paper, Brian Perry and Karl Rich summarise the differential impacts of FMD and its control, and link these findings with the growing understanding of how the control of this globally important disease may contribute to the processes of pro-poor growth in certain countries of the developing world.
