Strongyloid nematodes in the caeca of donkeys in Henan Province, China

Abstract

Thirty-four donkeys from Henan Province, China, were examined at necropsy for strongyloid nematodes in the caecum (February 2006 to January 2007. Twenty-two species, including 18 Cyathostominae (small strongyles) and 4 Strongylinae (large strongyles), were identified. The five most prevalent Cyathostominae were Cylicocyclus nassatus (73.5%), Coronocyclus labratus (70.6%), Coronocyclus labiatus (67.6%), Cyathostomum tetracanthum (61.8%) and Coronocyclus coronatus (52.9%), accounting for 70.2% of all species identified; C. labratus (124.2 ± 256.4), Cyathostomum tetracanthum (96.4 ± 210.5) and Cylicocyclus nassatus (80.9 ± 117.1) had the greatest mean abundance, whereas Strongylus vulgaris was the most prevalent (88.2%) of the Strongylinae and had the highest mean abundance (34.9 ± 37.8). The numbers of species per donkey ranged from 1 to 15 (with a median of 7.1). Only a small percentage (5.9%) of donkeys were infected by a single species, whereas the other donkeys had infections with multiple species.

Assessment of cardiovascular disease in the donkey: clinical, echocardiographic and pathological observations

“…There are publications about physiological variables for donkeys for working animals (Mueller and others 1994, Matthews and others 1998, Maloiy and others 2003, Ayo and others 2008) including clinical pathology reference data (Folch and others 1997, Palanivel and others 2008, Stanisic and others 2015). Parasitism is of considerable importance in this species, and a range of publications reflect this (Tolliver and others 1985, Wells and others 1998, Uslu and Guclu 2007, Bu and others 2009, Asefa and others 2011, Matthews and Burden 2013). A large, retrospective review of postmortem results from 1444 sedentary donkeys (DS records) has recently provided valuable information about the frequency of conditions resulting in donkey morbidity (Morrow and others 2011).…”

Mitochondrial DNA Evidence Supports the Hypothesis that Triodontophorus Species Belong to Cyathostominae

“…Equine strongyles, a large group of intestinal nematodes that belong to members of Equidae, are classified into two subfamilies, Strongylinae (large strongyles) and Cyathostominae (small strongyles), based on worm size and capsule mouth shape (Lichtenfels et al, 2008 ; Traversa et al, 2010 ). Although equine strongyles are the significant nematode pathogens of horses, information on these nematodes is limited to their morphology, prevalence, and disease control and prevention (Bu et al, 2009 ; Lyons et al, 2011 ; Mughini et al, 2011 ; Morariu et al, 2016 ; Singh et al, 2016 ). Intestinal nematodes of Cyathostominae, a ubiquitous parasitic nematode species, inhabit the large intestine of infested equines with a high prevalence, especially because of the reduced prevalence of Strongylus spp.…”

Phylogenetic analysis of the genus Cylicocyclus (Nematoda: Strongylidae) based on nuclear ribosomal sequence data

“…Strongylid nematodes are common parasites of horses, donkeys, mules and zebras (Gawor 1995;Bucknell et al 1995;Silva et al 1999;Collobert-Laugier et al 2002;Chapman et al 2003;Anjos and Rodrigues 2006;Bu et al 2009). They are major pathogens of horses causing pica, anaemia, even death, and leading to significant economic losses (Krecek and Guthrie 1999).…”
