Ecdysteroids are steroid hormones involved in moulting and development of arthropods. Blood samples 32 individual bats eight insectivorous species were analysed for the presence ecdysteroids, using liquid chromatography mass spectrometry. Nine ecdysteroids detected. The spectrum these was similar bat which take their preferred food items from same insect order. blood-borne broader autumn than s...
The role of mammalian skin in harbouring and transmitting arthropod-borne protozoan parasites has been overlooked for decades as these pathogens have been regarded primarily as blood-dwelling organisms. Intriguingly, infections with low or undetected blood parasites are common, particularly in the case of Human African Trypanosomiasis caused by Trypanosoma brucei gambiense. We hypothesise, ther...
BACKGROUND Apicomplexan tick-borne pathogens that cause disease in companion animals include species of Babesia Starcovici, 1893, Cytauxzoon Neitz & Thomas, 1948, Hepatozoon Miller, 1908 and Theileria Bettencourt, Franca & Borges, 1907. The only apicomplexan tick-borne disease of companion animals that is known to occur in Australia is babesiosis, caused by Babesia canis vogeli Reichenow, 1937 ...
conclusions it may be concluded that parasites are common in vegetables that are frequently eaten raw, and the use of tap water does little to remove them. regarding the results of this study, the importance of vegetables in the transmission of intestinal parasites is stressed, and it is necessary to improve the sanitary conditions of these kinds of food. results the findings of forty three sam...
BACKGROUND The extent to which climate change may affect human health by increasing risk from vector-borne diseases has been under considerable debate. OBJECTIVES We quantified potential effects of future climate change on the basic reproduction number (R0) of the tick vector of Lyme disease, Ixodes scapularis, and explored their importance for Lyme disease risk, and for vector-borne diseases...
Aim Comparative studies have revealed strong links between ecological factors and the number of parasite species harboured by different hosts, but studies of different taxonomic host groups have produced inconsistent results. As a step towards understanding the general patterns of parasite species richness, we present results from a new comprehensive data base of over 7000 host–parasite combina...
The switching of parasitic organisms to novel hosts, in which they may cause the emergence of new diseases, is of great concern to human health and the management of wild and domesticated populations of animals. We used a phylogenetic approach to develop a better statistical assessment of host switching in a large sample of vector-borne malaria parasites of birds (Plasmodium and Haemoproteus) o...
Rickettsia spp, Babesia spp, and Ehrlichia spp. are all responsible for emerging tick-borne diseases within the United States. The intention of this study was to complete a survey of American dog ticks and rodent hosts for the presence of all three parasites in order to determine which animals acted as hosts for each parasite in the midwestern United States, and how common each parasite was wit...
