“…epg counts in both experiments, L 3 from this species were not found in faecal cultures or herbage samples. As reported by Oliver et al (2014); Van Dijk and Morgan (2009); Yazwinski and Tucker (2006), this peculiarity could be explained by a lack of thermal or mechanical stimulus and short time for L 3 to hatch and develop, respectively. The differences between GP genera identified in the environment and faecal cultures are associated with multiple variables that interact with FMU (Fiel et al, 2012;Saumell et al, 2015;Saumell et al, 2008), in contrast to optimal and controlled laboratory conditions.…”

“…Very prevalent globally, N. spathiger is a parasite nematode of the small intestine, widely shared between domestic and wild ruminants (Hoberg et al, 2001). It has been reported in Lama guanicoe (Petrigh & Fugassa, 2014), in domestic bovids (Oliver et al, 2014;Zhao et al, 2014), in many African wild bovids (Junker et al, 2015), and in Sub-Saharan antelopes (Said et al, 2017). The infections due to N. spath-iger may go generally unnoticed except in juveniles where the larval stages migration cause tissue lesions within the intestinal mucosa, which is expressed by diarrhea and dehydration (Kaufmann, 2013).…”

Monitoring of gastrointestinal nematode parasites in ruminants (domestic and wild) is often based on fecal examination techniques, looking for excreted eggs and larval forms using morphological keys. These, are more available in domestic ruminants, in which helminths are widely studied, than in wild ruminants. This study tried to provide certain morphological elements that will help to recognize the L3 larvae of Camelostrongylus mentulatus and Nematodirus spathiger that could parasite either domestic or wild ruminants. For that, we resorted first to the culture of L3 larvae from fecal samples taken from African antelopes, and second by the microscopic characterization of each isolated larval morphological pattern previously identified by sequencing of its internal transcribed spacer (ITS-2) regions of the ribosomal DNA. The results of different microscopic captured images showed that Camelostrongylus mentulatus larva is 16 intestinal cells that measuring approximately 820 µm length, ‎≈ 25 µm wide, and ‎≈ 47 µm for its sheath tail extension and by this be closer to Teladorsagia circumcincta characteristics. For Nematodirus spathiger, it possesses 8 gut cells and measuring about 1020 µm long, ‎≈ 25 µm wide, and‎ ≈ 143 µm for its sheath tail extension with specific tail appendages. Have done this, we were able to get some clarifications on the morphology of the studied larvae, and we believe thus that this study will contribute to the establishment of morphological identification keys especially for parasitic nematodes of wild ruminants.

“…For example, scientists report that among ruminants on the territory of New Zealand, 100 % (50/50) of the studied population of nematode nematodes of the species N. spathiger were isolated, and 76 % (38/50) of the animals were N. filicollis (Oliver et al, 2014). At the same time, in Canada, the infestation of calves by causative agents of nematodirosis was at the level of 1.7 % (Jelinski et al, 2017).…”

The most common helminthiasis of cattle is strongylidosis of the digestive organs. This group of animal helminthiasis is widespread in Ukraine and is caused by nematodes of the Strongylida suborder, among which nematodirosis occupies a leading place. Invasion leads to a decrease in productivity, the quality of the obtained products, barrenness of the broodstock, and deterioration of the growth and development of the young. Invasion of definitive hosts occurs mostly passively; by alimentary means, the invasive is the larva of the third stage. The work aimed to conduct monitoring studies of the epizootic situation regarding the spread of nematodirosis of cattle in the territory of Poltava region based on the results of the analysis of statistical data of the reporting documentation of the Main Department of the State Production and Consumer Service in Poltava region for 2018–2022. It was established that the extent of nematodirosis infestation in cattle ranged from 0.81 % (in 2020) to 5.30 % (2022), with the average extensiveness of the invasion for the studied period at 1.36 %. At the same time, the share of nematodirosis among other nematode diseases of cattle was 18.37 %. Among other nematodes, neoascarosis, bunostomosis, esophagostomosis, dictyokaulosis, and trichurosis were diagnosed in the territory of the studied region, the share of which ranged from 1.51 to 51.51 %. Among the invasive diseases of cattle registered on the territory of the Poltava region, the share of trematodes (fasciolosis, dicroceliosis, paramphistomatosis) in the general parasitic pathology is 85.51 %, protozoans (eimeriosis, babesiosis) and nematodes – 8.67 and 5.78 %, respectively, for cestodoses (moniasis) – 0.04 %. The obtained data from monitoring studies indicate the relevance of a more in-depth study of the spread of nematodirosis infestation among cattle in farms of the Poltava region, taking into account the nematode fauna, the characteristics of the infestation of animals of different age groups, in different seasons of the year, and as part of mixed infestations with other parasites.
