Opegaster ouemoensis sp. n. is described from Periophthalmus argentilineatus Valenciennes (Gobiidae). Distinctive features included the weak or undetectable papillae of the ventral sucker and the small, but distinct cirrus-sac. The new species is compared with 25 marine species of Opegaster for which a table of measurements and ratios is presented. The new combination Opegaster queenslandicus (...

The Hualapai vole (Microtus mogollonensis haulpaiensis) is an endangered rodent occurring in northwestern Arizona. Helmiths were examined from 47 voles collected from 9 localities in northwestern Arizona. A toal of 375 helminths was collected, including 2 species of cestodes Anoplocephaloides troeschi and Paranoplocephala macrocephala, and 1 cecal nematode Syphacia obvelata. Pinworms were the m...

Pritchardia boliviensis n. gen. n. sp. (Anoplocephalidae: Linstowiinae) is described from marsupials (Marmosops noctivagus, Metachirus nudicaudatus, Gracilinanus sp.) collected in Bolivia and Paraguay. These cestodes have a very small strobila with only three segments, regularly alternating genital pores, genital ducts crossing excretory canals ventrally, ovoid to pyriform cirrus sac, three to ...

Cestodes Since 1993 (1) several cases of sparganosis caused probably by Spirometra sp. have been observed. (5,6 and Samarasinghe S, personal communication). Bertiella studeri, an anoplocephalid tapeworm, is now recognised as a parasite acquired in areas where monkey reservoir hosts abound (7). As summarised by the present author (8) this cestode (Weerasooriya MV, Edirisinghe JS, personal commun...

Leopardus colocolo, Leopardus geoffroyi, Leopardus tigrinus and Puma yagouaroundi are wild feline species endangered mainly due to habitat destruction and vehicle run overs. Seventeen felines hit on the roads were collected in Southern Brazil and examined for parasites. Cestodes were identified as Mesocestoides sp. The parasites were found in the small intestine of the hosts with a prevalence o...

We tested the null hypothesis that populations of hosts trapped in isolated neighbouring locations showing comparable habitat quality, should support similar helminth parasite communities. The study was undertaken in a 2-week period in late summer in NE Poland in a single year, thereby eliminating seasonal and between-year variation in parasite burdens. A total of 139 Clethrionomys glareolus (b...

Parasitic gastro-enteritis leads to a serious health threat with a limitation to the productivity of small ruminants due to the associated morbidity, mortality, cost of treatment and prophylaxis (Nwosu et al., 2007). Parasitic infections are of much economic importance because small ruminants' rearing has become a major source of income particularly to the marginal farmers in the country (Patha...
