Health and epidemiological approaches of Trypanosoma evansi and equine infectious anemia virus in naturally infected horses at southern Pantanal. Repositório Alice

Equine infectious anemia virus (EIAV) and Trypanossoma evansi are endemic in Brazilian Pantanal Biome,an important area for livestock production. In this sense, we evaluated the epidemiological single andco-infection effects of T. evansi and EIAV in naturally infected horses in the southern Pantanal wetland byserological tests and hematological assays. Both higher seroprevalence and heath poor condition of thesampled animals were associated with differences in horse management between farms. We found thatthe negative animals for both infectious agents (NN) represented the major group in F1 (37%), and thesmallest group in F2 (19%). Furthermore, we recorded higher EIAV seroprevalence (56%) in F2, comparedto F1 (38%). We observed that T. evansi infection was...

Prevalence and risk factors for Equine Infectious Anemia in Poconé municipality, northern Brazilian Pantanal. Repositório Alice
BORGES, A. M. C. M.; SILVA, L. G.; NOGUEIRA, M. F.; OLIVEIRA, A. C. S.; SEGRI, N. J.; FERREIRA, F.; WITTER, R.; AGUIAR, D. M..
Serum samples collected from 547 equids in the Pantanal region of Brazil were evaluated for antibodies to Equine Infectious Anemia Virus (EIAV) by the agar gel immunodiffusion test. Risk factors associated with EIAV seropositivity were evaluated and spatial dependence investigated using a Spatial Lag Model. EIAV prevalence on farms in the Pantanal was 52.0% (13/25) with adjusted prevalence between equids of 31.5% (17.4?48.8% 95% CI). Intra-herd prevalence ranged from 5.0 to 77.0%. Statistical analysis demonstrated that farms and animals in regularly flooded areas had respectively 60 and 146 fold higher chance to be sero-positive than farms and animals located in non-flooded areas. Spatial Lag Model results were generally consistent with this conclusion...
