“…Others report the distribution of E. trivolvis and E. caproni in rodents and domestic poultry (Huffman and Fried 1990). Some suggest that rodents are also the natural hosts of E. paraense (Huffman 2000). Experimentally, rodents can be infected with E. hortense (Saito 1984) and E. ilocanum (Lie and Nasemary 1973).…”

Rodents are the most abundant and diversified order of living mammals in the world. Already since the Middle Ages we know that they can contribute to human disease, as black rats were associated with distribution of plague. However, also in modern times rodents form a threat for public health. In this review article a large number of pathogens that are directly or indirectly transmitted by rodents are described. Moreover, a simplified rodent disease model is discussed.

“…Kennedy (1976) suggested separating dispersal and transmission when analyzing egg release; wide dispersal in space and time would best be served by continuous release over long periods of time, while rhythmic release would increase the probability of transmission. Examination of egg release by E. caproni over a period of weeks or months (Odaibo et al, 1988;Huffman, 2000;Mu˜noz-Antoli et al, 2007) showed a pattern of constant release and increasing production per mouse in the early stages of the infection, followed by a plateau of several weeks, with a subsequent decline. In the current study, feces were released by at least 1 mouse in all collection periods and all fecal samples contained eggs.…”

“…Long-term egg production by Echinostoma caproni has been studied in some detail by various authors (Odaibo et al, 1988;Huffman, 2000;Mu˜noz-Antoli et al, 2007); these studies show an increase in egg production over the first few weeks of patency followed by a plateau phase and then a gradual decline after several months. This pattern is consistent with the dispersal component of egg release as described by Kennedy (1976).…”

Circadian egg production by Echinostoma caproni was investigated in ICR mice. Four female mice were infected with 25 E. caproni metacercariae, maintained in individual cages on a 12:12 light:dark cycle, and provided food and water ad libitum. Twenty-eight, 51, and 58 days post-infection, mice were transferred to individual, wire-bottomed cages and feces were collected every 2 hr for 24 hr. The feces were weighed and processed immediately to estimate the number of eggs present. Fecal output and egg production were standardized to unit maxima for analysis. Standardized egg count and standardized fecal output followed distinctly circadian patterns and covaried. Egg production was highest from 2200 to 0200 hr and lowest from 1000 to 1800 hr. These correspond to the highest and lowest fecal production, and highest and lowest periods of host activity, respectively. Egg density (eggs/g of feces) covaried weakly with fecal output with an additional peak at 0800-1000 hr, suggesting E. caproni is responding to changes in host physiology in timing of the production and release of eggs into the intestine. The continuous production and release of eggs during the patent period, coupled with the circadian pattern of daily egg release by E. caproni , would result in the widest dispersal of eggs in the host environment and enhance transmission to the first intermediate host.

“…However, as observed by Huffman (2000) , the impact of echinostomes on wildlife health is significant, and these digeneans play an important role as causative agents of diseases in waterfowl and aquatic mammals. Most of the known cases are of migratory birds debilitated during their migrations.…”

“…Massive infection may induce a clinical picture of enteritis followed by hemorrhagic diarrhea, which could result in the death of animals (Huffman 2000) . In the naturally infected water rodent, N. squamipes parasitized with E. paraensei , it was possible to observe transitory parasitism, which lasted no longer than a few weeks Animals generally harboring a few worms developed only minimal pathologic alteration (personal observation).…”
