Bottom Line: According to the data provided by slaughterhouses, the parasite was more frequent in the cities of Atílio Vivácqua, Itapemirim and Anchieta with respective prevalence of 28.41, 25.50 and 24.95%.Although the northern portion of the state is also favorable for the disease maintenance (reaching rates above 90%), several cities presented prevalence of only 0.99 and 1.94% respectively.Regarding the slaughterhouse located in Anchieta city, the higher prevalence was registered in the cities of Jerônimo Monteiro, Alegre and Cachoeiro de Itapemirim, with mean prevalence of 1.21, 1.07 and 2.09% respectively.

ABSTRACT

Background: Fasciolosis affects different ruminant species and leads to great economic losses for cattle farmers worldwide. Thus, the current study aimed to evaluate bovine fasciolosis prevalence in the state of Espírito Santo, Brazil, using slaughter maps provided by slaughterhouses and verifying the origin of cattle.

Methods: A map was created based on analysis of epidemiological data. The ArcGIS/ArcINFO 10.1 software was employed in order to elaborate updated bioclimatic maps that displayed the fasciolosis prevalence within the state - per city- between 2009 and 2011.

Results: According to the bioclimatic map it was clear that 52.24% of the state's total area comprise regions considered favorable for the development and survival of Fasciola hepatica. According to the data provided by slaughterhouses, the parasite was more frequent in the cities of Atílio Vivácqua, Itapemirim and Anchieta with respective prevalence of 28.41, 25.50 and 24.95%. Although the northern portion of the state is also favorable for the disease maintenance (reaching rates above 90%), several cities presented prevalence of only 0.99 and 1.94% respectively. These findings indicate that climatic and environmental factors only cannot be considered preponderant to fasciolosis occurrence. Regarding the slaughterhouse located in Anchieta city, the higher prevalence was registered in the cities of Jerônimo Monteiro, Alegre and Cachoeiro de Itapemirim, with mean prevalence of 1.21, 1.07 and 2.09% respectively.

Conclusion: Although the present findings suggest a pattern for the prevalence of fasciolosis, records of the cities for the occurrence of the disease usually do not reflect the true origin of animals.

Figure 3: Map showing the prevalence of bovine fasciolosis in the state of Espírito Santo from 2009 to 2011.

Mentions: Therefore, maps generated by distribution, based on rates of prevalence from 11 slaughterhouses distributed throughout the state and monitored by SIF and SIE were combined. Results indicated that slaughterhouses in Atílio Vivácqua, Cachoeiro de Itapemirim and Anchieta presented higher rates of discarded livers, with mean prevalence of 28.41, 25.50 and 24.95% respectively (Table 2).Regarding data presented in Figure 3, it was observed that maps generated by distribution showed areas with higher significance for the occurrence of the disease in the south of the state. They presented average rates that varied from 1.21 to 28.41%.
