“…Hymenolepis diminuta requires an arthropod intermediate host to complete its life cycle. The main intermediate hosts are the mealworm beetle ( Tenebrio molitor ), the four beetle ( Tribolium confusum ) and the northern rat flea ( Nosopsyllus fasciatus ) [22]. The variation found in the prevalence could be related to the abundance of intermediated hosts in each area.…”

A survey of zoonotic pathogens carried by house mouse and black rat populations in Yucatan, Mexico

SUMMARY The house mouse (Mus musculus) and the black rat (Rattus rattus) are reservoir hosts for zoonotic pathogens, several of which cause neglected tropical diseases (NTDs). Studies of the prevalence of these NTD-causing zoonotic pathogens, in house mice and black rats from tropical residential areas are scarce. Three hundred and two house mice and 161 black rats were trapped in 2013 from two urban neighbourhoods and a rural village in Yucatan, Mexico, and subsequently tested for Trypanosoma cruzi, Hymenolepis diminuta and Leptospira interrogans. Using the polymerase chain reaction we detected T. cruzi DNA in the hearts of 4·9% (8/165) and 6·2% (7/113) of house mice and black rats, respectively. We applied the sedimentation technique to detect eggs of H. diminuta in 0·5% (1/182) and 14·2% (15/106) of house mice and black rats, respectively. Through the immunofluorescent imprint method, L. interrogans was identified in 0·9% (1/106) of rat kidney impressions. Our results suggest that the black rat could be an important reservoir for T. cruzi and H. diminuta in the studied sites. Further studies examining seasonal and geographical patterns could increase our knowledge on the epidemiology of these pathogens in Mexico and the risk to public health posed by rodents.

“…Although those studies do not identify the source of infections in children, exposure is likely to occur as a result of accidental ingestion of infected intermediate hosts (e.g. beetles) or by direct ingestion of R. nana eggs (Baker, 2007). We recognize several limitations of this study, most notably the small sample size and the inability to estimate the intensity of infection with the fl otation technique.…”

Research Note. Occurrence of gastrointestinal helminths in commensal rodents from Tabasco, Mexico

et al. 2017

SummaryThe aim of this study was to determine the prevalence and species composition of helminths in commensal rodents captured inside private residences in the city of Villahermosa in Tabasco, Mexico. Trapping was performed at each house for three consecutive nights from October to December 2015. Fifty commensal rodents were captured: 23 Rattus norvegicus, 16 Mus musculus and 11 Rattus rattus. Rodents were transported alive to the laboratory and held in cages until they defecated. Feces were analyzed for helminth eggs using the Sheather's fl otation technique. The overall prevalence of helminths in rodents was 60 %: R. norvegicus was more likely to be parasitized (87.0 %) than R. rattus (63.6 %) and M. musculus (18.8 %). Eggs from at least 13 species of helminths were identifi ed: Hymenolepis diminuta, Rodentolepis nana, Moniliformis moniliformis, Heligmosomoides polygyrus, Heterakis spumosa, Mastophorus muris, Nippostrongylus brasiliensis, Strongyloides ratti, Syphacia obvelata, Syphacia muris, Toxocara sp., Trichosomoides crassicauda, and Trichuris muris. This is the fi rst study to report the presence of H. polygyrus, S. ratti and T. crassicauda in commensal rodents in Mexico. In conclusion, our results suggest that helminths commonly infect commensal rodents in Villahermosa and therefore rodents present a health risk to inhabitants in this region.

“…The three most frequently encountered rodent pinworm species are Aspiculuris tetraptera, Syphacia obvelata and S. muris. These nematodes do not usually cause overt clinical disease in affected rodents, but alterations in host physiology have been reported 3 . In live rodents, Syphacia sp.…”

“…Postmortem diagnostic testing is considered more reliable than these methods and involves direct examination of the rodent's cecal and colon contents for adult worms. Taxonomic classification of an adult nematode can be accomplished by microscopic examination of its head and tail 3 .…”

A cost-effective and efficacious method of pinworm treatment for large colonies of mice

Rodent pinworm infestations are common in modern animal facilities, and treatments to eradicate these nematodes are often costly and labor-intensive. The authors describe a method they developed to treat rodents with ivermectin using the automatic watering system available at their facility. This delivery method proved an efficacious and cost-effective means of eradicating Aspiculuris tetraptera from a large colony of mice. The system might also be used to provide other orally administered agents to mice and other species.
