| classification of the main macroscopic lesions produced by larvae of gasterophilus spp. (diptera:gasterophilidae) in free-ranging horses in umbria. | listed and described herein are the main macroscopic lesions produced along the whole digestive tract of free-ranging horses by larvae of the five gasterophilus spp., occurring in umbria, a region of central italy: gasterophilus intestinalis, gasterophilus nasalis, gasterophilus pecorum, gasterophilus inermis, gasterophilus haemorrhoidalis. lesions are classified on the basis of their sizes and shapes and the host's anatomic sites infested, and they are examined in relation to the developmental ... | 1988 | 3335129 |
| species composition of gasterophilus spp. (diptera, oestridae) causing equine gastric myiasis in southern italy: parasite biodiversity and risks for extinction. | horse gastrointestinal myiasis caused by larvae of gasterophilus spp. (diptera, oestridae) flies has a worldwide distribution and, where present, it is primarily caused by larvae of gasterophilus intestinalis and gasterophilus nasalis. other species, i.e., gasterophilus inermis, gasterophilus pecorum and gasterophilus haemorrhoidalis, present in different or in the same regions of the gastrointestinal tract, were only occasionally reported in very limited areas of eastern european countries and ... | 2005 | 15978726 |
| utility of mitochondrial and ribosomal genes for differentiation and phylogenesis of species of gastrointestinal bot flies. | larvae of gasterophilus spp. (diptera: oestridae) cause gastrointestinal myiasis of equids. however, their identification may be problematic due to morphological similarities between species infesting identical regions of the digestive tract. in this study, genes encoding for mitochondrial cytochrome oxidase i (coi) and for the 16s and 28s ribosomal subunits of the most commonly encountered gasterophilinae subfamily species [i.e., gasterophilus haemorrhoidalis (l.), gasterophilus inermis (brauer ... | 2005 | 16539155 |
| comparative scanning electron microscopy of gasterophilus third instars. | comparison of cuticular features, including spine distribution and shape, structure of the maxillae and mandibles, the cephalic sensillae and the terminal abdominal segments of third instar gasterophilus haemorrhoidalis, gasterophilus inermis, gasterophilus intestinalis, gasterophilus meridionalis, gasterophilus nasalis and gasterophilus pecorum was conducted using scanning electron microscopy. one or more features distinguished among the species, with the exception of g. haemorrhoidalis and g. ... | 2007 | 17897366 |
