Cooperia Oncophora
''Cooperia oncophora'' is one of the most common intestinal parasitic nematodes in cattle in temperate regions. Infections with ''C. oncophora'' may result in mild clinical symptoms, but can lead to weight loss and damage of the small intestine, especially when co-infections with other nematodes such as '' O. ostertagi'' occur. Infections are usually treated with broad-spectrum anthelmintics such as benzimidazole, but resistance to these drugs has developed in the last decades and is now very common. ''C. oncophora'' has a direct life cycle. Infective larvae are ingested by the host. The larvae grow to adults, which reproduce in the small intestines. Eggs are shed onto the pasture with the faeces, which leads to new infections. Co-infections with other gastro-intestinal nematodes such as '' O. ostertagi'' and '' H. contortus'' are common. Morphology ''C. oncophora'' females are about 6–8 mm long, males about 5.5–9 mm. They are light red in color and have a coiled ...

Nematode
The nematodes ( or grc-gre, Νηματώδη; la, Nematoda) or roundworms constitute the phylum Nematoda (also called Nemathelminthes), with plant-Parasitism, parasitic nematodes also known as eelworms. They are a diverse animal phylum inhabiting a broad range of environments. Less formally, they are categorized as Helminths, but are taxonomically classified along with Arthropod, arthropods, Tardigrade, tardigrades and other moulting animalia, animals in the clade Ecdysozoa, and unlike platyhelminthe, flatworms, have tubular digestion, digestive systems with openings at both ends. Like tardigrades, they have a reduced number of Hox genes, but their sister phylum Nematomorpha has kept the ancestral protostome Hox genotype, which shows that the reduction has occurred within the nematode phylum. Nematode species can be difficult to distinguish from one another. Consequently, estimates of the number of nematode species described to date vary by author and may change rapidly over ...

Trichostrongylus
''Trichostrongylus'' species are nematodes (round worms), which are ubiquitous among herbivores worldwide, including cattle, sheep, donkeys, goats, deer, and rabbits.Garcia LS, editor. Diagnostic Medical Parasitology. 5 ed. Washington, DC: ASM Press; 2007.Strickland GT, editor. Hunter's Tropical Medicine and Emerging Infectious Diseases. 8 ed. Philadelphia, PA: WB Saunders Company; 2000. At least 10 ''Trichostrongylus'' species have been associated with human infections. Infections occur via ingestion of infective larvae from contaminated vegetables or water. Epidemiological studies indicate a worldwide distribution of ''Trichostrongylus'' infections in humans, with the highest prevalence rates observed in individuals from regions with poor sanitary conditions, in rural areas, or who are farmers / herders. Human infections are most prevalent in the Middle East and Asia, with a worldwide estimated prevalence of 5.5 million people. Life cycle Eggs are passed through the feces of ...

Dictyocaulus
''Dictyocaulus'' is a genus of nematode parasites of the bronchial tree of horses, sheep, goats, deer, and cattle. ''Dictyocaulus arnfieldi'' is the lungworm of horses, and ''Dictyocaulus viviparus'' is the lungworm affecting ruminants. ''Dictyocaulus viviparus'': lungworm of cattle, deer ''Dictyocaulus viviparus'' is the most common lungworm of cattle; the infection is also known as ''husk'' or '' parasitic bronchitis''. Although classified as the same parasite, some people believe that the ''D. viviparus'' of deer and elk should be reclassified as a different species, including ''D. eckertii'' in New Zealand. However, both species have been shown capable of cross-infecting cattle and cervids (at least in New Zealand) . The parasite has a simple but interesting life cycle, with dispersal facilitated by a fungus. Adult ''D. viviparus'' worms reside in the bronchial tree of the animal's lungs. They lay eggs into the airways (bronchi). These eggs are coughed up and subsequ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
