Drugs and Biologics

Drugs and Important Biological Agents (IBA) related to Ostertagiasis:

1.	MorantelIBA 06/20/1981 - "The efficacy of a morantel sustained release bolus to control ostertagiasis in grazing calves was assessed. " 06/20/1981 - "Studies on the control of bovine ostertagiasis using a morantel sustained release bolus." 01/01/1986 - "During the grazing season one group had received fenbendazole at fortnightly intervals to suppress trichostrongyle infections, one received a morantel sustained release bolus before grazing to limit trichostrongyle contamination of the pasture, and the control group was only medicated when heavy infections caused clinical type 1 ostertagiasis. "
2.	Ivermectin (Mectizan)FDA Link 02/01/1988 - "The use of ivermectin and the newer benzimidazoles in intermittent or slow release devices should prove highly effective in the control of Type I and II ostertagiasis, as well as of subclinical ostertagiasis. "
3.	BenzimidazolesIBA 02/01/1988 - "The use of ivermectin and the newer benzimidazoles in intermittent or slow release devices should prove highly effective in the control of Type I and II ostertagiasis, as well as of subclinical ostertagiasis. "
4.	FenbendazoleIBA 05/30/1981 - "As a result of these trials and previous reports it is concluded that a single oral dose of fenbendazole cannot be relied upon to prevent winter (type 2) ostertagiasis." 10/01/1977 - "The treatment of ostertagiasis type II in cattle, using fenbendazole in feed blocks." 01/01/1986 - "During the grazing season one group had received fenbendazole at fortnightly intervals to suppress trichostrongyle infections, one received a morantel sustained release bolus before grazing to limit trichostrongyle contamination of the pasture, and the control group was only medicated when heavy infections caused clinical type 1 ostertagiasis. "
5.	CopperIBA 11/01/1990 - "Effect of ostertagiasis on copper status in sheep: a study involving use of copper oxide wire particles." 01/01/1988 - "Interstitial haemorrhage of the ileocaecal valve, with the accumulation of haemosiderin and ferritin in undifferentiated macrophages was observed in some of these cattle and also in others with experimentally-induced copper deficiency and acute ostertagiasis. "
6.	NitrogenIBA 01/01/1973 - "The pathophysiology of ovine ostertagiasis: some nitrogen balance and digestibility studies."
7.	benzimidazoleIBA 01/01/1988 - "A study on the effects of tactical drenchings with a benzimidazole against ostertagiasis in calves."
8.	Pepsinogen A (Pepsinogen)IBA 04/01/1988 - "The latter group showed a mean peak faecal egg count of 655 eggs per gram (e.p.g.) in October associated with high serum pepsinogen concentration and clinical signs of ostertagiasis, compared with a peak of 119 e.p.g. " 02/01/1988 - "Determination of serum pepsinogen levels is useful in evaluating the risk or presence of ostertagiasis Type I in a herd. " 11/01/1987 - "Multiple forms of bovine pepsinogen: isolation and identification in serum from calves with ostertagiasis." 05/01/1986 - "From the results it appears that adult O ostertagi play a significant role in the elevated plasma pepsinogen levels associated with bovine ostertagiasis." 10/01/1983 - "Moderate to severe abomasal pathology and elevated plasma pepsinogen were associated with ostertagiasis in the pastured calves. "
9.	GastrinsIBA 02/01/1988 - "Serum gastrin levels are, generally, increased in animals with ostertagiasis. " 06/01/1981 - "The elevation of abomasal pH which occurs in ostertagiasis may result in increased gastrin levels but is thought not to be the only cause since plasma gastrin increased before the abomasal pH rose and developed in sheep infected for a second time although their abomasal contents remained at pH 4.0 or lower. " 01/01/1979 - "Ovine tissue and serum gastrin in ostertagiasis." 02/01/1976 - "These data are consistent with the hypothesis previously stated that in ostertagiasis the hypersecretion from fundic pouches is due to increased levels of circulating gastrin." 01/01/1993 - "For gastrin, it is suggested that based on group means, values of 400 pg/ml are indicative for subclinical parasitic disease in calves with reduced daily weight gain, while threshold levels of > or = 1000 pg/ml gastrin are representative for clinical ostertagiasis. "
10.	AntigensIBA 02/01/1988 - "Serologic responses to L3-derived antigen of approximately 32 kDa may be unique and diagnostic for cattle harboring inhibited larvae, or pre-Type II ostertagiasis. " 02/01/1984 - "Lymphocyte reactivity to Ostertagia ostertagi L3 antigen in type I ostertagiasis."
