Summary
Cyathostomins, or small redworms, are common equine parasites. Their control is challenging due to drug resistance and knowledge gaps in host immunity and parasite community dynamics.
Area of Science:
- Veterinary Parasitology
- Equine Health
- Infectious Diseases
Background:
- Cyathostomins (small strongyles/redworms) are widespread equine parasites residing in the large intestine.
- Infections can range from sub-clinical to severe, including acute larval cyathostominosis.
- Widespread drug resistance complicates effective control strategies.
Purpose of the Study:
- To provide a comprehensive review of cyathostomin biology and host-parasite interactions.
- To identify critical knowledge gaps hindering sustainable parasite control.
- To inform future research and management strategies for equine cyathostominosis.
Main Methods:
- Literature review of cyathostomin biology, epidemiology, and control.
- Analysis of host-parasite relationships and immune responses.
- Examination of community dynamics within mixed cyathostomin populations.
Main Results:
- Cyathostomins exhibit diverse biology and inhabit various climatic regions.
- Significant knowledge gaps exist regarding equine immune responses to cyathostomins.
- Understanding mixed parasite population dynamics is crucial for effective control.
Conclusions:
- Sustainable cyathostomin control requires addressing widespread drug resistance.
- Further research into equine immunity and parasite community dynamics is essential.
- Integrated parasite management strategies are needed to combat cyathostominosis.

01:15Anthelminthic Agents
Anthelmintic drugs differ significantly from antiparasitic therapies targeting protozoa, primarily due to differences in parasite biology. Whereas most protozoal treatments act on proliferating cells, anthelmintics are typically directed against mature, nonproliferative helminths. The therapeutic approach considers the helminth's reliance on neuromuscular coordination, glucose metabolism, and microtubular integrity for survival, reproduction, and localization within the host. Most anthelmintics...
01:22Indirect-Acting Cholinergic Agonists: Pharmacokinetics
Indirect-acting cholinergic agonists, or anticholinesterases, enhance the body's cholinergic activity by inhibiting acetylcholine's breakdown. They are categorized as reversible or irreversible agents based on their mechanism of action. They are further classified into short-acting, intermediate-acting, and long-acting agents based on their duration of action.
Reversible agents containing quaternary amines, such as neostigmine and edrophonium, are not easily absorbed orally because they are...

01:29Indirect-Acting Cholinergic Agonists: Chemistry and Structure-Activity Relationship
Indirect-acting cholinergic agonists are agents that interact with the acetylcholinesterase enzyme in the synaptic cleft, preventing the breakdown of acetylcholine into choline and acetate. Consequently, the concentration of acetylcholine in the synaptic cleft increases. These agonists can be classified into reversible and irreversible inhibitors based on their duration of action.
Reversible inhibitors display short to medium durations of action. Short-acting agents include simple alcohols with...

01:33Overview of Secretory Vesicles
Secretory vesicles, also known as dense core vesicles (DCVs), are membrane-bound vesicles that transport secretory proteins, such as hormones or neurotransmitters. Regulated secretory vesicles transport proteins from the trans-Golgi network to the exterior of the cell. Proteins present in regulated secretory vesicles are required to be rapidly exocytosed in large amounts upon a specific stimulus.
Various proteins regulate the aggregation of molecules inside the secretory vesicles. Chromogranins...

01:31Direct-Acting Cholinergic Agonists: Pharmacokinetics
Direct-acting cholinergic agonists, such as synthetic choline esters and naturally occurring alkaloids, exert their effects by enhancing the actions of acetylcholine and stimulating the parasympathetic nervous system. Synthetic choline esters share structural similarities with acetylcholine. For example, they have a positively charged quaternary ammonium or onium group, contributing to their hydrophilic characteristics. As a result, they are poorly absorbed in the body through oral...
01:28Acid Suppressive Drugs for Peptic Ulcer Disease: Histamine H2-Receptor Antagonists
Histamine H2 receptors, which are intricately located on the basolateral membrane of parietal cells, play a crucial role in modulating gastric acid secretion. When released from enterochromaffin-like cells, histamine engages H2 receptors, initiating the cyclic AMP (cAMP) pathway. In this pathway, adenylyl cyclase converts ATP into cAMP, elevating intracellular cAMP levels. The activation of protein kinase A follows, stimulating the proton pump. This stimulation prompts the secretion of hydrogen...
