“…The prepatent period of A. tetraptera is about 23 days. (Taffs, 1976). Although pinworm parasites of laboratory rodents are generally considered relatively non-pathogenic and infections are generally regarded as symptomless, no specific clinical signs appear even with serious infections.…”

“…It seems that cestodes and trematodes have nervous systems different from those of nematodes (Frayha et al, 1997). Due to the fact that pinworm eggs have been found on equipment, in dust and in ventilation air-intake ducts, drug therapy should be backed by routine hygienic measures (Habermann & Williams, 1958;Taffs, 1976). The aim of this study was to investigate the effectiveness of orally administered ivermectin diluted in water as a treatment for adult pinworms and their larvae in laboratory rat colonies, and to evaluate the safety of the drug with respect to growth rate, behaviour and consumption of food and water.…”

233 SummaryThe effects of ivermectin were studied in laboratory rats naturally infected with the pinworm Syphacia muris. Ivermectin was administered over four 5-days periods in drinking water; the ivermectin dose was 2.5 mg/kg of body weight per day. All the rats were weighed every five days and their ova production was monitored by a cellophanetape test. Every fifth day six males and six females from the experimental group were euthanized and examined for adult pinworms and larvae. The rats' health condition, behaviour and consumption of food and water were monitored every day. The aim of this study was to investigate the effectiveness of orally administered ivermectin as a treatment against adult pinworms and their larvae in laboratory rat colonies.

“…The innocuous reputation of pinworms in rodents is at least questionable as they have been thought to affect weight gain and growth rate; in addition various disorders of the intestine have been attributed to oxyurids (Hoag 1961, Harwell & Boyd 1968, Flynn 1973, Pearson & Taylor 1975, Taffs 1976, Wagner 1988. Immunocompromised rodents, such as nude mice, are predisposed to large worm burdens, sequelae or death (Jacobson & Reed 1974).…”

Effective eradication of pinworms (Syphacia muris, Syphacia obvelata and Aspiculuris tetraptera) from a rodent breeding colony by oral anthelmintic therapy

SummaryAn 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.

“…A similar relationship exists between Mus musculus and Syphacia obvelata, where the parasites are found both in free-living populations of the mouse and in its laboratory strains (e.g. Behnke 1975, Taffs 1976, Hasslinger and Wiethe 1987, Pisanu et al 2003. …”

A nematode Dentostomella translucida was found during parasitological examination of a pet Mongolian gerbil Meriones unguiculatus. Gerbils in the wild are known as hosts of this parasite in Asia, pet gerbils -in the USA and Brazil. Our record is the first in Europe. Complete descriptions of male and female individuals are given. KeywordsNematoda, Heteroxynematidae, Dentostomella translucida, gerbils, pets * Corresponding author: zalesny@microb.uni.wroc.plThe oxyurid Dentostomella translucida Schulz et Krepkorgorskaya, 1932 is a nematode parasitizing the large intestine of gerbils. It was originally described by Schulz and Krepkorgorskaya (1932) from the great gerbil Rhombomys opimus Lichtenstein, 1823.According to Ryzhikov et al. (1979) the parasite occurs in Asian countries, mainly Kazakhstan, Turkmenistan and Uzbekistan. Later infections with D. translucida were recorded also in pet gerbils from the United States (Wightman et al. 1978) and Brazil (Pinto et al. 2003). To date the parasite has not been reported in Europe.During a standard parasitological dissection 13 nematodes were found in the caecum of a pet Mongolian gerbil Meriones unguiculatus Milne-Edwards, 1867 which died for unknown reasons. The parasites were fixed and kept in 70% ethanol, then cleared for examination in glycerol. Complete morphometric data were obtained from 5 adult females and 4 juvenile males.In order to find out if infection with this nematode was common among the gerbils from pet shops in Wroc³aw, faecal samples for coprological analyses were collected from 6 gerbil colonies. They were examined for the presence of parasite eggs, using the standard flotation method with saturated solution of sodium chloride.The results were compared with available data which describe D. translucida in details (Ryzihkov et al. 1979 andPinto et al. 2003). Our material conforms to the previous descriptions of the species. The measurements of the most representative structures of D. translucida, expressed in millimetres (mean ± standard deviation, range in brackets), are given below.Females: Body 22.23 ± 3.03 (19.15-26.50) long, 0.40 ± 0.05 (0.31-0.44) wide. Head with 4 submedian papillae, lips absent, buccal cavity shallow (Fig. 1A, C). Oesophagus 0.34 ± 0.02 (0.32-0.36) long. Excretory pore not observed. Vulval aperture 10. 48 ± 0.76 (9.95-11.35) from anterior extremity. Eggs oval, asymmetrical, 0.123 ± 0.006 (0.110-0.130) long, 0.044 ± 0.002 (0.038-0.048) wide (Fig. 1D). Anus 0.58 ± 0.13 (0.48-0.77) from the posterior end (Fig. 1B).Males (juvenile specimens): Body 9.69 ± 1.48 (7.56-11.00) long, 0.26 ± 0.03 (0.23-0.28) wide. Head structures same as described for females. Oesophagus 0.27 ± 0.01 (0.25-0.28). Excretory pore not observed. Caudal alae wide (Fig. 1E). Single spicule 0.34 ± 0.01 (0.33-0.34) long with round-
