犬细小病毒感染的病因分析与防治对策

摘  要

本文探讨了犬细小病毒感染的临床表现、病因分析及防治对策。犬细小病毒感染主要表现为肠炎型和心肌炎型两种形式,前者常见于成年犬及幼犬,症状包括食欲不振、呕吐、血便等;后者则多见于幼犬,致死率高。病因方面,病毒的高传播性、宿主免疫力下降、饲养管理不当以及病毒变异均为重要因素。为有效防治犬细小病毒感染,本文提出了加强疫苗接种、保持犬只均衡饮食、合理控制饲养密度以及密切监测病毒变异情况等对策。这些措施旨在提高犬只的免疫力,减少病毒感染的机会,同时针对病毒的变异特性,及时调整防治策略,以期达到更好的防治效果。本研究对于保障犬类健康、减少细小病毒感染的发生和传播具有重要意义,也为宠物医疗领域提供了有价值的参考。

Abstract

This paper discusses the clinical manifestations, etiology analysis and prevention countermeasures of canine parvovirus infection. Canine parvovirus infection is mainly manifested as enteritis type and myocarditis type two forms, the former is common in adult dogs and puppies, the symptoms include loss of appetite, vomiting, blood stool, etc.; the latter is more common in puppies, high mortality rate. In terms of etiology, the high transmissibility of the virus, decreased host immunity, improper feeding management and viral mutation are all important factors. In order to effectively prevent and control parvovirus infection in dogs, this paper proposes countermeasures to strengthen vaccination, maintain a balanced diet, reasonably control feeding density and closely monitor virus mutation. These measures aim to improve the immunity of dogs, reduce the chance of virus infection, and at the same time to adjust the mutation characteristics of the virus, in order to achieve better prevention and control effect. This study is of great significance for ensuring dog health and reducing the occurrence and spread of parvovirus infection, and also provides a valuable reference for the pet medical field.

Keywords:Canine parvovirus; etiology analysis ;prevention countermeasures
