The helminth fauna of the house mouse (Mus musculus Linnaeus, 1758) was studied on the basis of 429 host individuals from the suburban area of Belgrade. Eleven helminth species were recorded: three cestode species - Catenotaenia pusilla, Rodentolepis fraterna, and Cysticercus (= Strobilocercus) fasciolaris [larval stage of Taenia taeniaeformis (Batsch, 1821)]; and eight nematode species - Heligmosomoides polygyrus, Syphacia sp., Aspiculuris tetraptera, Syphacia obvelata, Heterakis spumosa, Trichuris muris, Mastophorus muris, and Gongylonema sp. Within the general helminth fauna, H. polygyrus was found to be the most prevalent species (39.2%) and caused the highest infection intensity. Prevalences of A. tetraptera, C. pusilla, and S. obvelata ranged from 12.8% to 6.1%, while the remaining species showed prevalences ranging from 4.9% (for Syphacia sp.) to 0.2% (for Gongylonema sp.). All the species found in males were also present in females, with the exceptions of M. muris and Gongylonema sp. No significant differences were found between males and females regarding prevalence (P%), mean infection intensity (MI), or mean abundance (MA).

AbstractA field study was conducted to disclose the prevalence of different helminth parasites in the black rat, Rattus rattus, in some regions of Stara Zagora district, Bulgaria. Out of 67 examined rats, 53 (79.1%) were found to be positive. Helminths of three classes were detected such as Cestoda: Hymenolepis diminuta (47.8%), Hymenolepis nana (43.3%), Taenia taeniaeformis larvae (7.5%), Taenia polyacantha larvae (1.5%); Secernentea: Syphacia obvelata (4.5%), Aspiculuris tetraptera (3.0%) and Adenophorea: Capillaria hepatica (9.0%), Trichuris muris (3.0%). Of all the investigated rats, 27 (40.3%) were infected by one helminth species and 26 (38.8%) by more than one. Hymenolepis diminuta was a predominant species in cases of single infections (23.9%). The most frequent co-infections were observed by H. nana and H. diminuta (16.4%).

Proceratophrys boiei is an endemic cycloramphid anuran inhabiting the leaf litter of Atlantic rainforests in Southeastern Brazil. We analyzed the whole digestive tract of 38 individuals of Proceratophrys boiei collected in two Atlantic Rainforest areas in the state of Rio de Janeiro, Brazil, to study the diet composition and the helminth fauna associated with this species. The main food items in P. boiei's diet were Coleoptera, Orthoptera and Blattaria. Five nematode species were found: Aplectana delirae, Cosmocerca parva, Oxyascaris oxyascaris, Physaloptera sp. (larval stage only) and an unidentified nematode. Overall prevalence was 71% and mean infection intensity was 7.3 ± 5.8 neatodes per individual.

AbstractThe helminths of two sympatric species of rodents, the striped field mouse Apodemus agrarius and the yellow-necked mouse, Apodemus flavicollis from Slovakia were studied to determine whether there are similarities in the composition of the helminth fauna of two closely related host species living in the same area. A total of twelve species of helminths were identified in these rodent populations, including Brachylaima sp. (Trematoda); Hymenolepis diminuta (Rudolphi, 1819), Mesocestoides sp. larvae, Rodentolepis fraterna (Stiles, 1906), Rodentolepis straminea (Goeze, 1782), Skrjabinotaenia lobata (Baer, 1925), Taenia taeniaeformis larvae (Batsch, 1786) (Cestoda); Aonchotheca annulosa (Dujardin, 1845), Heligmosomoides polygyrus (Dujardin, 1845), Heterakis spumosa Schneider, 1866, Mastophorus muris (Gmelin, 1790) and Syphacia stroma (Linstow, 1884) (Nematoda). In A. agrarius, H. polygyrus was the most prevalent, as well as the most abundant helminth, but R. fraterna was the species with the highest mean intensity. In contrast, S. stroma dominated the A. flavicollis helminth fauna with the highest prevalence, mean abundance and mean intensity. Both rodent populations harboured nine helminth species, although the mean individual species richness was significantly higher in A. agrarius than in A. flavicollis. The analysis of helminth diversity at both component and infracommunity levels revealed differences between the two rodent populations, which are most likely attributable to the specific host ecology.

Summary The 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 flotation 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 identified: 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 first 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.

Cytological aspects of gametogenesis are studied in the common oxyuroid (Nematoda) parasites of Mus musculus, Syphacia obvelata (Oxyuridae) and Aspiculuris tetraptera (Heteroxynematidae). Both species are shown to be haplodiploid: males develop from unfertilized eggs and are haploid and females develop from fertilized eggs and are diploid. In female A. tetraptera there are 12 chromosomes in oogonial divisions; meiosis is normal and six bivalents were observed in ova. There are two maturation divisions and embryos in eggs in utero contain 6 or 12 chromosomes. In males, there are six chromosomes in spermatogonial divisions; there is a single maturation division and all spermatozoa have six chromosomes. Gametogenesis was similar in Syphacia obvelata but the chromosome numbers are four in males and eight in females.

Abstract Objectives Rodents play an important role to spread zoonotic diseases through society. The current study was carried out to collect informative data on the intestinal helminthic infections of wild rodents in Taleqan County, Alborz Province, the center of Iran, emphasizing their zoonotic aspects. Results Sixty-two killed rodents by local farmers belonging to five species were collected, among which 24 were identified as Mus musculus, 15 as Meriones persicus, 12 as Meriones libycus, 10 as Apodemus witherbyi, and 1 as Dryomys nitedula. Of them, 30 (48.4%) were infected with at least one helminth species. Rodents were infected with Hymenolepis diminuta (42%), Syphacia obvelata (21%), Hymenolepis nana (17.7%), Heligmosomoides polygyrus (9.6%), Trichuris muris (8%), and as well as a capillariid nematode that was isolated for the first time from D. nitedula in Iran. The findings of the present study revealed a significant intestinal helminthic infection of rodents in Taleqan County. Improving hygiene practices, and making a preventive attitude can be helpful to reduce the hazards of rodent-borne diseases in the area where humans, livestock, and synanthropic rodents are living close to each other.

AbstractA survey was carried out of the levels of infection with Aspiculuris tetraptera and Syphacia obvelata in a wild house mouse population living in the Charles Clore Small Mammals Pavilion at the London Zoo in Regent's Park. The extent of infection with A. tetraptera is analysed according to the sex of the host. It is shown that the prevalence of infection was greater in male than in female mice and frequency distribution studies suggest that this is not only because fewer female mice become infected but also because females resist larvae more effectively than do males.

El ratón común Mus musculus Linnaeus, 1758 es empleado comúnmente como modelo de investigación en las ciencias veterinarias y biomédicas. Cuarenta organismos fueron colectados en cuatro diferentes bioterios de la Universidad Nacional Autónoma de México y fue evaluada la presencia de parásitos. La examinación intestinal reveló al nematodo Aspiculuris tetraptera (Nitzsch, 1821) Schulz, 1927 (n=104) y Syphacia obvelata Rudolphi, 1802 (n=1582). El análisis estadístico determinó que no hay preferencia parasitaria por sexo del hospedero. Se registró al cestodo Rodentolepis nana (Siebold, 1852) sinónimos (Hymenolepis nana y Vampirolepis nana) que son causantes de cestodiasis en el humano. Este trabajo tiene un énfasis en estos helmintos debido a su potencial zoonótico. No se detectó la presencia de ectoparasitos. Se elaboró un reporte del registro de parásitos en roedores de bioterio en México obtenido de una base de datos de la Colección Nacional de Helmintos del Instituto de Biología de la Universidad Nacional Autónoma de México. Este es un primer registro preliminar de la ocurrencia del nematodo A. tetraptera y S. obvelata en el ratón común M. musculus en cuatro bioterios en la ciudad de México. Este trabajo amplía la distribución geográfica y contribuye también, a un nuevo registro del parásito.

Aspiculuris Tetraptera

AbstractWild house mice, naturally infected with Aspiculuris tetraptera were segregated according to their weight into six age groups. The prevalence of infection and the mean worm burden of these mice were studied in the different age groups. The overall prevalence of infection was high (57% or more) in all the groups except the youngest. Mice acquired larvae soon after weaning; the highest larval burdens were reached in juvenile mice and the highest mature worm burdens, a group later, in mature mice. Older mice had fewer larvae and fewer mature worms. The mature worm burdens decreased but relatively slower than the larval burdens. It is suggested that either innate or acquired resistance could account for these observations.
