“…The fertility, mortality and behaviour of the host population depend on how the parasites were distributed within it (Hudson and Dobson 1995). The first human case of hepatic capillariasis, was reported in Korea (Choe et al 1993). All together, only 37 cases of human capillariasis (Slais 1974).…”

Patho-physiological observations in natural concurrent infections of helminth parasites of zoonotic importance in the wild rodents, Bandicota bengalensis

et al. 2016

Screening of 83 mature wild rodents of Bandicota bengalensis (52 male and 31 females), live trapped from premises near railway station, fish market and agricultural fields in Ludhiana district of Punjab province, India was carried out to assess the natural occurrence of helminth parasites and their potential as reservoirs of zoonoses. On necropsy, intestine of rats was found infected with adult cestode parasites of Hymenolepis diminuta and H. nana. Liver was found infected with Capillaria hepatica and Cysticercus fasciolaris. These parasites were present either alone or as concurrent infection. In overall, 68.67 % rats were found infected of which 59.65 % were infected with nematode parasite, C. hepatica and 75.44 % with cestode parasites. Grossly, pathognomonic lesions of C. hepatica and C. fasciolaris were seen clearly and microscopic changes were observed only in severely infected cases. Overall investigation on the effect of these parasitic infections on pathophysiology of the host revealed that rodents serve as reservoirs of these parasitic infections without having much pathogenic effect on their vital organs, fecundity and enzyme activities. Because of its close association with human habitations, B. bengalensis may act as an important source of zoonotic infections and thus direct or indirect contact with excrements and carcasses of this rodent species, should be avoided.

“…6,13,18,24,27 Although human infection is rare, it is reported to be relatively more frequent in children. 3,4,7,22,31 The prevalence of C hepatica infection in rodents is reported worldwide with variable infection prevalence ranging from 7.9% to 88.0%. 6,21,23,32,33,37 In the present study, 23.6% of captured wild rats from the selected areas of Korea were infected with C hepatica.…”

Prevalence of Hepatic Parasites in Korean Wild Rats (Rattus norvegicus) and Their Association With Pulmonary Arteriolar Medial Hypertrophy

C hepatica, an important zoonotic parasite, and C fasciolaris are common parasites in rodents. In rodent livers, C hepatica causes sequential morphologic changes that are designated as early, intermediate, or late phase, and C fasciolaris forms cysts surrounded by fibroplasia and granulomatous inflammation. The present study describes the prevalence of these parasites and associated liver and lung lesions in wild rats (Rattus norvegicus) living around pig farms in South Korea. Selected parenchymal organs, including liver and lung, of 89 wild rats were examined. Of 89 rats, 28 (31.5%) were infected with either C hepatica or C fasciolaris or with both parasites. Severe medial hypertrophy of small arterioles was observed in the lungs of 11 of the 28 parasite-infected rats (P < .01). The pulmonary arteriolar hypertrophy in the rats infected with C hepatica was strongly associated with early and/or intermediate phases (88.8%) of morphologic change in the livers (P < .01). As such, this report is the first to suggest a significant association between parasite-induced hepatitis and pulmonary arteriolar hypertrophy in rodents. Further studies are warranted for the use of C hepatica-infected rats as an animal model to explore the underlying mechanisms of portopulmonary hypertension in humans.

“…Because ingestion of infected soil is a route of infection, particularly among children, gardening can result in contaminated dirt on vegetables being inadvertently consumed. 3,10,13 A more comprehensive study of the extent of C. hepatica infection in rats throughout Diego Garcia may provide more information on potential regional differences in infection relative to differing rat densities relative to habitat types. …”

Capillaria hepatica infection in black rats (Rattus rattus) on Diego Garcia, British Indian Ocean Territory

et al. 2015

Rats ( Rattus spp.) are among the most damaging invasive species worldwide. The accidental introduction of rats has caused significant detriment to native flora and fauna, crops, structures, and human livelihoods. Rats are vectors of disease and carriers of various zoonotic parasites. Capillaria hepatica (syn. Callodium hepaticum) is a parasitic nematode found primarily in rodents but is known to infect over 140 mammal species, including human beings and several species of domestic animals. In this case study, the presence of C. hepatica infection in black rats on Diego Garcia, British Indian Ocean Territory, is reported. Liver samples from 20 black rats ( Rattus rattus) were collected during a concurrent population density estimation study. Histology revealed 15 (75%) of the rats sampled had a current or previous infection with C. hepatica. In addition, a larval cestode compatible in size and shape with Cysticercus fasciolaris, the larval stage of Taenia taeniaeformis of cats, was found in 3 (15%) of the rats sampled. The high prevalence of C. hepatica infection in rats on Diego Garcia has implications for human health given the high population density of rats found on the island.
