To the Editor: In April 2009, a 47-year-old woman in Saint-Jeannet in southern France reported stomach aches, abdominal bloating, and occasional diarrhea. Blood analyses found an increased eosinophil level (8,800 cells/mm 3), which represented 52% of 16,900 leukocytes/mm 3. Parasitologic examinations for helminths were conducted with 6 fecal specimens obtained during June 9– July 2, 2009. Analy...

To the Editor: Human fascioliasis, infection with Fasciola spp. flukes, is highly pathogenic in both acute and chronic phases and can result in death (1). This disease has been recently emerging, in part linked to climate and global changes (2). Human Fasciola infection has been reported in 5 continents and is related to the disease’s wide spread in livestock. Guilan Province in northern Iran i...

During October 1998 a study was performed in the Caledon area to determine the presence of anthelmintic resistance in the southern Western Cape, which falls within the winter rainfall region of South Africa. The study took the form of an undifferentiated faecal egg count reduction test (FECRt) survey. The predominant worm genera of the region are Teladorsagia and Trichostrongylus, but Haemonchu...

Levels of parasitism and the dynamics of helminth systems is subject to the impact of environmental conditions such that we may expect long term increases in temperature will increase the force of infection and the parasite's basic reproduction number, R0. We postulate that an increase in the force of infection will only lead to an increase in mean intensity of adults when adult parasite mortal...

Long-term studies have been the backbone of population ecology. The red grouse Lagopus lagopus scoticus is one species that has contributed widely to this field since the 1950s. This paper reviews the trajectory and profound impact that these studies have had. Red grouse research has combined long-term studies of marked individuals with demographic studies over wide geographical areas and repli...

The known chromodorolides A (1) and B (2), and a new derivative chromodorolide C (3) have been isolated from an Australian sponge and characterized by 1D and 2D NMR experiments. The chromodorolides exhibited significant cytotoxicity against the P388 mouse leukaemia cell line, and also showed activity against the freeliving larval stages of the parasitic nematodes Haemonchus contortus and Tricho...
