Eprinomectin is extensively used in veterinary medicine, particularly in the treatment of internal and external parasites in livestock, including goats. The pharmacokinetic behavior of eprinomectin in plasma and faeces was studied after a single subcutaneous administration in two different goat breeds at a dose of 0.2 mg/kg body weight.

Contamination of the food and especially marine environment with nano/micro-plastic particles has raised serious concern in recent years. Environmental pollution and the resulting seafood contamination with microplastic (MP) pose a potential threat to consumers. The absorption rate of the MP by fish is generally considered low, although the bioavailability depends on the physical and chemical properties of the consumed MP.

Tetrodotoxin (TTX) is a crystalline, weakly basic, colorless organic substance and is one of the most potent marine toxins known. Although TTX was first isolated from pufferfish, it has been found in numerous other marine organisms and a few terrestrial species. Moreover, tetrodotoxication is still an important health problem today, as TTX has no known antidote.

Sheep and goats are sharing different helminth parasites including Haemonchus contortus. Control of these helminths is based mainly on the use of anthelmintics. However, in goats, the application of anthelmintics is often carried out mainly at dosages determined for sheep without knowing the real effects and metabolism features.

Article Synopsis
  • The study evaluated the residue levels of spinosad (SPN) and abamectin (ABM) in eggs and edible tissues of laying hens after spray application to control external parasites.
  • A total of 36 hens were treated with different concentrations of SPN and ABM, and eggs were collected for 30 days, with hens sacrificed afterward for tissue analysis.
  • While ABM residues were undetectable in eggs, SPN levels were within safe limits for eggs and most tissues; however, higher residues were found in skin tissue, suggesting a necessary withdrawal period post-treatment.

Internal parasites of horses comprise an intractable problem conferring disease, production and performance losses. Parasitism can rarely be controlled in grazing horses by management alone and anthelmintic drugs have formed the basis of therapy and prophylaxis for the last sixty years. The pharmacology of the anthelmintic drugs available dictate their spectrum of activity and degree of efficacy, their optimal routes of administration and characteristics which prevent some routes of administration, their safety tolerance and potential toxicities and as a consequence of their persistence in the body at effective concentrations their use in epidemiological control programmes.

Background: Meloxicam (MLX) is a nonsteroidal anti-inflammatory drug used in the relief of postoperative pain for human and veterinary medicine. This study was designed to investigate the effect of surgery on the plasma disposition of MLX in dogs undergoing ovariohysterectomy following a single intravenous injection at a dose of 0.2 mg/kg bodyweight.

Mebendazole (MBZ) has been licensed for use in horses and donkeys, however there are no data available in the literature regarding its pharmacokinetic disposition and efficacy in donkeys. This study was designed to determine the plasma disposition, milk excretion and anthelmintic efficacy of MBZ in donkeys naturally infected by Cyathostominae. The animals were allocated to three groups, each of six donkeys.

Background: The aims of this study were to compare the pharmacokinetics of albendazole sulfoxide (ABZ-SO, ricobendazole) in goats and sheep at a dose of 5 g/kg bodyweight (BW), after intravenous (IV) and subcutaneous (SC) administrations, and to investigate the effects of increased doses (10 and 15 mg/kg BW) on the plasma disposition of ABZ-SO in goats following SC administration. A total of 16 goats (Capra aegagrus hircus, eight males and eight females) and 8 sheep (Ovis aries, four males and four females) 12-16 months old and weighing 20-32 kg, were used. The study was designed according to two-phase crossover study protocol.

Since there is no registered anthelmintic drug available for use in goats, extra-label use of drugs is a common practice in most countries. The aim of the present study was to compare the pharmacokinetic disposition of levamisole (LVM)-oxyclozanide (OXZ) combination in sheep and goats following per os administration. Goats (n = 8) and sheep (n = 8) 12- to 16-months-old were used for this study.

The sucking louse Haematopinus tuberculatus (Burmeister 1839) is an ectoparasite of buffaloes, cattle, camels, and American bison. Alphacypermethrin (ACYP) is a pyrethroid insecticide commonly used to control arthropods of veterinary and public health interest. Therapeutics, such as antiparasitic compounds, is often administered to buffaloes based on dosage and intervals recommended for cattle because very few drugs have buffalo-specific label indications.

The macrocyclic lactones have pharmacokinetic properties which enhance their use against endo- and ectoparasites in animals and man. The most consistent physico-chemical feature of the group which contributes to their kinetic characteristics is high lipid solubility. This appears to be necessary for their pharmacodynamic action as well as common kinetic features such as large volumes of distribution and the influence of body fat composition on their disposition.

Routine use of transcutaneous bilirubin (TcB) measurement in the newborn nursery could reduce costs, readmission rates for hyperbilirubinemia and the need for total serum bilirubin (TSB) measurements. The aim of this study was to examine the correlation between TcB measurement, as performed using BiliCheck, and TSB, measured with high-pressure liquid chromatography (HPLC) and with standard laboratory methods, and to determine the TcB cutoff points with desirable sensitivity and specificity values for various clinically relevant TSB levels by HPLC. Fifty-four infants of > or = 30 weeks of gestational age were enrolled in the study.
