“…Gejala klinis yang muncul akibat haemonchosis adalah anemia (bisa sampai dengan parah), hipoproteinemia, letargi, dan kematian (Ameen et al 2010;Hogg et al 2010;Al Gaabary et al 2012;Qamar & Maqbool 2012). Yazie & Gondar (2015); Besier et al (2016); serta Boukhari et al (2016) membagi haemonchosis ke dalam tiga kelompok berdasarkan intensitas infeksi dan respon inang, yaitu hiperakut, akut, dan kronis.…”

<p class="awabstrak2">Haemonchosis in sheep and goats has a high prevalence rate in several regions in Indonesia and causes economic losses. The purpose of this paper is to explain the clinical symptoms and pathological aspects of <em>Haemonchus contortus</em> infection so that knowledge is expected to help in controlling haemonchosis. Clinical symptoms of haemonchosis is characterised by decreased production, cachexia, and severe anaemia due to worms that sucking blood from the abomasal mucosa. In chronic infections the symptoms shows general oedema. Gross pathological findings are pale mucosa and carcass, hydrothorax, ascites, and haemorrhagic abomasum. Whereas histopathological features shows desquamation of villous abomasum, extensive hemorrhage of abomasal mucosa-submucosa, infiltration of large numbers of eosinophil and mononuclear cells, and cells undergoing degeneration and necrosis of internal organs. In general, the above exposure will show that haemonchosis usually associated with anaemia, cachexia, oedema, haemorrhage, infiltration of eosinophil and mononuclear cells in the abomasal mucosa.</p>

“…Adult worms are 2-3 cm long and reside in the abomasum of their host, where they feed on blood obtained using the lancet in their buccal capsule. They have a host preference for sheep and goats, although they can infect cattle (Hogg et al, 2010), deer and camelids, and in sub-tropical regions, the closely related Haemonchus placei is a significant parasite of cattle (Jacquiet et al, 1998;Achi et al, 2003;Jabbar et al, 2014;Taylor et al, 2015). Adult worms have an average lifespan of approximately 50 days, and the female worms are extremely fecund, producing 1300-7000 eggs per worm per day (Getachew et al, 2007;Saccareau et al, 2017), compared with a range of 0-350 eggs per worm per day in Teladorsagia circumcincta (Stear and Bishop, 1999).…”

Haemonchus contortus is a trichostrongyle nematode parasite of sheep and goats, and worldwide is considered to be the most important parasite of these species. It has a similar lifecycle to other parasitic trichostrongyle gastrointestinal nematodes, but it has a markedly higher fecundity, a preference for higher temperatures and a short pasture development time, which makes it epidemiologically different. Similarly, because of its blood-feeding habit the disease produced is distinct from parasitic gastroenteritis. This article summarises the differences in biology and control of H. contortus to other gastrointestinal nematodes of sheep, and covers specific control measures such as the use of FAMACHA© scoring, use of closantel and nitroxynil, the H. contortus vaccine, the effect of copper oxide wire particles, and the potential for breeding haemonchosis-resistant sheep and other future developments in H. contortus control.

“…Haemonchus placei is most commonly found in cattle (Lichtenfels et al , 1994). Additionally, there are a few published reports on: (i) apparently pure infection of H. contortus in cattle (Hogg et al , 2010; Akkari et al , 2013; Chaudhry et al , 2014a); (ii) apparently pure infection of H. placei in small ruminants (Akkari et al , 2013); and (iii) H. contortus and H. placei co-infection in sheep, goats, cattle and buffalo (Amarante et al , 1997; Jacquiet et al , 1998; Achi et al , 2003; Gasbarre et al , 2009a, b; Brasil et al , 2012). Le Jambre & Royal (1980) discovered that the mating of H. contortus males with H. placei females results in the sterile first-generation male progeny, whereas the first-generation female progeny can produce offspring if backcrossed with males of one of the parental species (Le Jambre, 1981).…”

Insight into species diversity of the Trichostrongylidae Leiper, 1912 (Nematoda: Strongylida) in ruminants

This paper focuses on the species diversity among the Trichostrongylidae Leiper, 1912 (Nematoda: Strongylida), and complexity of the family systematics. Polymorphism (subfamilies: Ostertagiinae, Cooperiinae and Haemonchinae), the presence of cryptic species (genus: Teladorsagia) and hybridization (genera: Cooperia, Haemonchus and Ostertagia) are presented and discussed, considering both morphological and molecular evidence. Some of these phenomena are common, nevertheless not sufficiently understood, which indicates the need for expanding the current state of knowledge thereof. Within the Trichostrongylidae, species distinction supported merely by morphological features is difficult, and requires confirmation by means of molecular methods. The parasitic nematode taxonomy is complicated mainly by the genus Teladorsagia, but complexity may also be expected among other Ostertagiinae (e.g. in the genera Ostertagia and Marshallagia). The data presented here show that the members of the Trichostrongylidae can significantly complicate unambiguous species identification. Hence, it is essential to consider the phenomena mentioned, to gather valid and comparable data on the biodiversity of this family.
