“…Ogbourne (1976) and Collobert-Laugier et al (2002) reported the following preferred parts in descending order: dorsal colon (50 %; 64 %), ventral colon (45 %, 27 %) and caecum (5 %, 9 %). Only Stancampiano et al (2010) published results which differed from previous studies: the ventral colon (67.34 %), the caecum (27.52 %) and the dorsal colon (5. 14 %).…”

Stancampiano et al (2010), however, determined that the ventral colon (67.34 %), was the most preferred parts, followed by the caecum (27.52 %) and the dorsal colon (5.14 %). Reinemeyer et al (1988) and Lyons et al (2011) also observed the majority of adult worms in the ventral colon.…”

Cyathostominae distribution in experimentally infected ponies

SummaryNine ponies were experimentally infected with third stage cyathostome larvae. These animals were examined post-mortem for small strongyle infections from October 2011 to January 2012. Seventeen species of the following Cyathostominae genera were identifi ed: Coronocyclus, Cyathostomum, Cylicocyclus, Cylicostephanus, Gyalocephalus and Petrovinema. Of the 17 species of Cyathostominae recovered, Cyathostomum catinatum, Cyathostomum alveatum and Cylicocyclus nassatus were the most prevalent (100 %). From the entire population of Cyathostominae, 65.6 % were located in the caecum and only 34.4 % in the colon. Only 1,736 (24,6 %) females and 5,329 (75,4 %) males were observed. There was a signifi cant difference between the number of males and females in the genus Cyathostomum, Cylicocyclus and Gyalocephalus.

“…Interactions between intestinal helminths have been evidenced in diverse mammals (e.g., [13,31]), birds [32], fish [33], and invertebrates [34], with emphasis on parasite localization (e.g., [35]), abundance (e.g., [36]), life-history strategies, body size, and fecundity ( [37] and references therein) within the host. Nonetheless, many observational approaches used until recently generated inconsistent results on the importance of such interactions in structuring macro-parasite communities [13,[38][39][40].…”

Inter-specific interactions between parasites impact on parasite intra-host dynamics, host health, and disease management. Identifying and understanding interaction mechanisms in the wild is crucial for wildlife disease management. It is however complex because several scales are interlaced. Parasite-parasite interactions are likely to occur via mechanisms at the within-host level, but also at upper levels (host population and community). Furthermore, interactions occurring at one level of organization spread to upper levels through cascade effects. Even if cascade effects are important confounding factors, we argue that we can also benefit from them because upper scales often provide a way to survey a wider range of parasites at lower cost. New protocols and theoretical studies (especially across scales) are necessary to take advantage of this opportunity.

“…According to observation of Chapman et al (2003b), for a more accurate representation of species present in the strongylid community, one needs to identify at least 1,300 specimens if there are 2,000 or more worms present. However, most of researchers still continue to study the community of horse strongylids identifying only a small number of specimens-a few hundred (Gawor 1995;Osterman Lind et al 2007), or even a few dozen of worms (Stancampiano et al 2010). Such results lead to incorrect estimation of strongylid community structure and also cause omission from analysis of a number of rare species possessing low intensity of infection.…”

Three recently recognized species of cyathostomes (Nematoda: Strongylidae) in equids in Kentucky

2010

View full text Add to dashboard Cite

Three species of cyathostomes--Cylicocyclus ashworthi, Cylicostephanus bidentatus, and Cylicostephanus hybridus were identified recently in horses in Kentucky. General characteristics and distinguishing description of these species are presented. Distribution of these species and their role in the horse strongylid community are discussed. The importance of examining the entire contents of the large intestine or alternatively a high number of specimens in order to recover and identify species residing in low numbers is stressed.
