O cachorro-do-mato é um animal de difícil manejo, sendo necessária contenção anestésica para coleta de material biológico, dificultando a realização de exames de rotina. A alimentação essencialmente proteica oriunda de outros animais como leporídeos, roedores e aves não inspecionadas, aumenta o risco do parasitismo predatório e acidental causando agravos à saúde do animal.  A dificuldade de manuseio destes animais leva a escassez de literatura, assim objetivou-se relatar a presença de parasitismo por diferentes espécies de helmintos em cachorro do mato (Cerdocyon thous) mantido em cativeiro. Foi realizada uma visita clínica ao Criatório Conservacionista do Centro Universitário Cesmac. Ao exame clínico observou-se: apatia, perda de peso e pelos ressecados. Foi coletada amostra fecal e encaminhada ao Laboratório de Doenças Parasitárias da mesma instituição, onde foi submetida à técnica de Willis-Mollay. Constatou-se a presença de Ascaridia galli, Aspiculuris tetraptera, Syphacia obvelata e Passalurus ambiguus em grande quantidade, os quais são parasitas de galinha, roedores e coelho, respectivamente. O animal não havia sido vermifugado e recebeu esse tipo de alimentação meses antes da realização do exame coproparasitológico. Sugere-se que o animal seja portador e hospedeiro paratênico. É importante ressaltar, ainda, que a vermifugação, o monitoramento e a qualidade do alimento fornecido são determinantes para a prevenção e melhora da saúde e bem-estar desses animais.

Sanitary Conditions

The sanitary conditions of 13 animal houses in nine public institutions in Minas Gerais, and the presence of endo and ectoparasites of mice and rats colonies kept in these facilities were evaluated. Data about barriers to prevent the transmission of diseases and a program of sanitary monitoring were obtained through a questionnaire and local visit. Parasitological methods were performed for diagnosing mite, lice, helminthes, and protozoa parasites in 344 mice and 111 rats. Data have shown that the majority of the animal houses had neither proper physical environment nor protection barriers to prevent the transmission of infections. Parasitological results have shown that only one animal house (7.7%) had parasite free animals, whereas the others have presented infected animals and the prevalences of parasites in the mice colonies were: Myobia musculi (23.1%); Myocoptes musculinus (38.5%); Radfordia affinis (15.4%); Syphacia obvelata (92.3%); Aspiculuris tetraptera (23.1%); Hymenolepis nana (15.4%); Spironucleus muris (46.2%); Giardia muris (46.2%); Tritrichomonas muris (53.8%); Trichomonas minuta (61.5%); Hexamastix muris (7.7%); and Entamoeba muris (84.6%). As for the rat colonies, the prevalences were: Poliplax spinulosa (8.1%); Syphacia muris (46.2%); Trichosomoides crassicauda (28.6%); Spironucleus muris (85.7%); Tritrichomonas muris (85.7%); Trichomonas minuta (85.7%); Hexamastix muris (14.3%) and Entamoeba muris (85.7%).

SUMMARYThe egg-shell of Hammerschmidtiella diesingi and Aspiculuris tetraptera reduces the rate of water loss from the egg when exposed to desiccation. Staining of the enclosed larva by acid fuchsin and the collapse of eggs exposed to desiccation indicate that the permeability barrier is heat labile. This suggests that the lipid layer is the main permeability barrie of the shell. The complex structure of the uterine layers has a similar morphology to the respiratory structures of the chorion of some insect eggs. Reflections from the shell, the rate of embryonic development under various conditions and the penetration of lead ions indicate that the shell does not trap a layer of air when immersed in water and the uterine layers cannot, therefore, function as a plastron network. Calculations indicate that if diffusion is limited to the pores in the external uterine layer, the area available for gaseous exchange is reduced by 85·5% in H. diesingi, 95·6% in A. tetraptera and 96·8% in Syphacia obvelata. It is suggested that the uterine layers of oxyurid egg-shells function in a similar fashion to the pores in bird egg-shells and the aeropyles in the chorion of insect egg-shells which do not possess plastron networks. These structures reduce water loss from the egg whilst ensuring an adequate supply of oxygen for embryonic development.

AbstractA medicated diet containing 0.3% thiabendazole fed continuously to 26 mice for 7 days removed 9 out of 11 (82%) Hymenolepis nana, (one tapeworm remaining in each of two mice), 17 out of 17 (100%) Syphacia obvelata and 8 out of 8 (100%) Aspiculuris tetraptera infections. By contrast in 26 non-treated mice 9 out of 10 Hymenolepis, 17 out of 18 Syphacia and 8 out of 8 Aspiculuris infections persisted through the 7 day treatment period, and at post mortem examination 38 Hymenolepsis, 1,562 Syphacia and 4,911 Aspiculuris worms were recovered. In a second experiment 100% removal of 23 Hymenolepis and 20 Syphacia infections was obtained after 14 days medication of 38 mice. High activity against both roundyvorms and tapeworms of mice was thus obtained using one single drug. Some unexplained deaths amongst inbred strain C3H/Hef Nimr mice occurred within seven day's of the continuous medication.

Mice with a natural infection of Syphacia obvelata and Aspiculuris tetraptera were continuously medicated with 0·1% thiabendazole in the diet. No oxyurids were found in test animals after 24 days of treatment though control animals remained infected. Growth rates in treated animals increased. 2 generations of mice were studied and, although overall production fell by 1·45%, the use of this drug in total eradication of the worms is suggested.

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%).

An oral combination of piperazine and ivermectin was used over a 6-week period for treating three different colonies of mice or rats infested with Syphacia obvelata, Syphacia muris or Aspiculuris tetraptera. No acute toxic effect was found in transgenic lines of mice or rats with these products in a preliminary trial. The colonies were treated with piperazine, 2.1 mg/ml in tap water for 2 weeks, then with ivermectin, 0.007 mg/ml, in tap water for the third and fourth weeks, and finally with piperazine for two further weeks. Hygiene measures such as a complete cage change, thorough disinfection and cleaning of the rooms were associated with the treatment. All examinations subsequent to completion of treatment have proved negative for further parasites.
