High impact information on Spiruroidea

• Tetrameres (Tetrameres) megaphasmidiata n. sp. is described from the proventriculus of the two-banded plover, Charadrius falklandicus, and the white-rumped sandpiper, Calidris fuscicollis, from Patagonia, Argentina [1].
• Larval nematode parasites (Spiruroidea: Cystidicolidae) are recorded for the first time in Octopus vulgaris Cuvier, 1797 in the northeastern Atlantic Ocean [2].
• Trichostrongylus axei, Habronema muscae, S vulgaris, S edentatus, small strongyles, and Oxyuris equi were efficaciously eliminated in response to all doses of dienbendazole; Gasterophilus spp were not affected by any dose [3].
• The combined influences of (1) seasonal changes across the collective host population and (2) host subpopulations delineated by age were responsible for the overdispersed distributions of Oncicola canis, Physaloptera rara, and Protospirura numidica [4].
• Other helminths from these ocelots were Alaria marcianae, Brachylaima sp., Mesocestoides lineatus, Taenia rileyi, Oncicola canis, Dirofilaria immitis, Physaloptera rara, Ancylostoma tubaeformae, Cylicospirura chevreuxi, Vogeloides felis, and Metathelazia californica [5].

Anatomical context of Spiruroidea

• The gastrointestinal tracts of 167 of 489 (34%) Yarrow's spiny lizards (Sceloporus jarrovii jarrovii) collected in Pima County, Arizona (USA) from October 1967 through January 1970 were infected with Physaloptera retusa [6].

Associations of Spiruroidea with chemical compounds

• Curretted material digested in potassium hydroxide revealed fragments of larvae of the nematode suggestive of Draschia or Habronema [7].
• Fecal flotations, using magnesium sulfate solution, were performed in 12 of the 18 cases and were negative for Physaloptera eggs [8].
• Seven animals had gastric nematodosis (Physaloptera sp.), although three of them had been treated with a 14-day course of fenbendazole [9].
• Dissection of whole nematodes from formalin-fixed specimens revealed morphologic features consistent with Gongylonema macrogubernaculum, a species previously only reported in nonhuman primates [10].
• Efficacy of thiabendazole against intestinal nematodes such as Strongyloides, Trichuris, Physaloptera, Oesophagostomum and Capillaria was very satisfactory [11].

Gene context of Spiruroidea

• We report the finding of Tetrameres spirospiculum Pinto & Vicente, 1995 from Theristicus melanopis melanopis (Threskiornithidae) from Patagonia, Argentina [12].
