Abstract

Fasciolosis is caused by the fluke Fasciola hepatica in Brazil, which has a worldwide distribution and affects the bile ducts and liver parenchyma of several species of mammals, especially ruminants, and humans, configuring the disease as a zoonosis and generating a risk to global public health. In Brazil, the disease is considered endemic to some regions, mainly the South and Southeast, with emphasis on high rates in ruminants in the state of Espírito Santo. The present study aimed to carry out a spatio-temporal analysis of fasciolosis in ruminants in the state of Espírito Santo, from 2018 to 2023, based on slaughter maps carried out by the State Inspection Service (SIE) and Federal Inspection Service (SIF). Descriptive analysis, cross correlation and linear regression was carried out regarding the slaughterhouses and climate data and spatial distribution of notifications were represented in maps by the QGIS 3.28.1 program, using data from geographic bases made available by the Brazilian Institute of Geography and Statistics. The average annual frequencies of bovine fasciolosis for animals slaughtered under federal and state inspection were 0.829% and 5.53%, with a total average frequency of 4.35%. Results reveal differences between federal and state inspection and found a positive correlation between number of fasciolosis cases and rainfall. In an analysis from 2006 to 2023, a slaughterhouse in the South region presented an average frequency of 19.65% of fasciolosis in cattle. The study concluded that the state of Espírito Santo demonstrates a high frequency of fasciolosis in cattle, with the South region standing out with the highest frequency rates in slaughtered cattle, reinforcing the need for control measures for the disease in the region, minimizing the risks to public health as a consequence.

巴西圣Espírito州牛片形虫病的时空分析

片形吸虫病是由巴西的肝片形吸虫引起的，它在世界范围内分布，影响几种哺乳动物（特别是反刍动物）和人类的胆管和肝实质，使该疾病成为人畜共患病，并对全球公共卫生构成威胁。在巴西，这种疾病被认为是一些地区的地方病，主要是南部和东南部，重点是Espírito Santo州反刍动物的高发率。本研究旨在基于国家检验局（SIE）和联邦检验局（SIF）开展的屠宰地图，对2018年至2023年Espírito Santo州反刍动物片形虫病进行时空分析。利用巴西地理与统计研究所提供的地理数据库数据，利用QGIS 3.28.1程序对屠宰场的气候数据和通报的空间分布进行了描述性分析、互相关和线性回归。联邦和州检屠宰牛片形虫病年平均检出率分别为0.829%和5.53%，总平均检出率为4.35%。结果揭示了联邦和州检查之间的差异，并发现片形虫病病例数与降雨量呈正相关。在2006年至2023年的一项分析中，南部地区的一个屠宰场的牛片吸虫病平均发病率为19.65%。研究得出的结论是，Espírito Santo州的牛片吸虫病发病率很高，其中南部地区的屠宰牛片吸虫病发病率最高，这就加强了该地区对该疾病采取控制措施的必要性，从而最大限度地减少由此对公众健康造成的风险。

期刊介绍： Veterinary Parasitology: Regional Studies and Reports focuses on aspects of veterinary parasitology that are of regional concern, which is especially important in this era of climate change and the rapid and often unconstrained travel of people and animals. Relative to regions, this journal will accept papers of the highest quality dealing with all aspects of disease prevention, pathology, treatment, epidemiology, and control of parasites within the field of veterinary medicine. Also, case reports will be considered as they add to information related to local disease and its control; such papers must be concise and represent appropriate medical intervention. Papers on veterinary parasitology from wildlife species are acceptable, but only if they relate to the practice of veterinary medicine. Studies on vector-borne bacterial and viral agents are suitable, but only if the paper deals with vector transmission of these organisms to domesticated animals. Studies dealing with parasite control by means of natural products, both in vivo and in vitro, are more suited for one of the many journals that now specialize in papers of this type. However, due to the regional nature of much of this research, submissions may be considered based upon a case being made by the author(s) to the Editor. Circumstances relating to animal experimentation must meet the International Guiding Principles for Biomedical Research Involving Animals as issued by the Council for International Organizations of Medical Sciences (obtainable from: Executive Secretary C.I.O.M.S., c/o W.H.O., Via Appia, CH-1211 Geneva 27, Switzerland).
