“…During the encysted stage, the larvae are resistant to standard de-worming protocols. The larval stages of small strongyles can cause even more serious problems so that at the start of their invasion they may cause serious damage to the intestinal mucosa (Collobert-Laugier et al 2002). On the other hand, when the cyst wall is ruptured by an emerging larva, the accumulated excretory and secretory products are released, creating foci of intense mucosal inflammation (Smith 1976).…”

Larval cyathostominosis in a working donkey

2013

Parasitic infections are one of the most common factors that threaten the health and working performance of donkeys. One of the life threatening parasites is the small strongyles that encyst or burrow into the large intestine and their larvae can initiate severe damage in the lining of the intestine. A 6 years old female donkey with clinical signs of diarrhea and emaciation was necropsied and gross examination of gastro-intestinal tract revealed thin-walled, hyperemic and hemorrhagic cecum. Multifocal petechial hemorrhages were particularly prominent in the submucosa of cecum. Parasitological examination revealed two cyathostomin species included Cylicocyclus elongatus and Cyathostomum pathratum. At microscopic examination, cross sections of cyathostomins larvae associated with parasitic granuloma were observed in the submucosa of cecum. The lesions were associated with nonsuppurative enteritis with infiltration of eosinophils, plasma cells, lymphocytes and macrophages in the intestinal mucosa, submucosa and lamina propria.

“…Reinemeyer et al (1988) and Lyons et al (2011) also observed the majority of adult worms in the ventral colon. Ogbourne (1976), Collobert-Laugier et al (2002) and Mfi tilodze and Hutchinson (1985) reported that a number of species showed a decreasing trend in the ventral colon (31; 11; 12), dorsal colon (30; 8; 5) and caecum (24; 2; 1). In this study, the majority of adult cyathostome nematodes (65.6 %) were concentrated in the caecum.…”

“…Only a few studies have been carried out on the site distribution of individual cyathostome species within the large intestine. Ogbourne (1976) and Collobert-Laugier et al (2002) reported the most preferred parts as follows (in decreasing order): dorsal colon (Ogbourne, 1976 -50 %;Collobert-Laugier et al, 2002 -64 %), ventral colon (45 %; 27 %) and caecum (5 %; 9 %). 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 %).…”

“…Nematodes of the subfamily Cyathostominae, known also as cyathostomes or cyathostomins, are common in Europe, and a large number of species have been observed (Collobert-Laugier et al, 2002;Hinney et al, 2011;Kuzmina et al, 2005;Kuzmina et al, 2007). These parasites are of enormous interest because of their major diversity, the high infection intensity and serious pathology associated with these infections.…”

“…Mfi tilodze and Hutchinson (1985), Ogbourne (1976), Collobert-Laugier et al (2002) and Lyons et al (2011) reported that the highest number of species prefer the ventral colon to the dorsal colon and caecum. 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.…”

Cyathostominae distribution in experimentally infected ponies

et al. 2015

View full text Add to dashboard Cite

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.
