Gastrointestinal zoonotic helminths of dogs and cats have a public health concern worldwide. We investigated the prevalence of gastrointestinal helminths of zoonotic significance in dogs and cats in lower Northern Thailand and utilized molecular tools for species identification of hookworms and Opisthorchis viverrini. Fecal samples of 197 dogs and 180 cats were collected. Overall prevalence of ...

IN the routine examination of stools for hookworm eggs the work of the .Rockefeller International Health Board has proved that the centrifuge increases the positive findings by just over ten per cent. This has been proved independently by the workers in Trinidad and in British Guiana their results being, curiously enough, identical within one place of decimals. It is obvious on consideration th...

new observations in recent years have accented differences between the two common hookworms, ancylostoma duodenale and necator americanus, with respect to modes of transmision and pathogenicity, and have established ancylostoma ceylanicum as a species distinct from a. braziliense. transmammary and paratenic transmission are now considered to be natural modes of infection in ancylostoma caninum ...

BACKGROUND Schistosomes and soil-transmitted helminths (STH) (hookworm, Trichuris trichiura and Ascaris lumbricoides) are widely distributed in developing countries where they infect over 230 million and 1.5 billion people, respectively. The parasites are frequently co-endemic and many individuals are co-infected with two or more of the species, but information on how the parasites interact in ...

Patterns of disease may take on irregular geographic shapes, especially when features of the physical environment influence risk. Identifying these patterns can be important for planning, and also identifying new environmental or social factors associated with high or low risk of illness. Until recently, cluster detection methods were limited in their ability to detect irregular spatial pattern...
