Risk factors for trypanosomiasis by Trypanosoma vivax in cattle raised in Rio Grande do Norte state

Arq. Inst. Biol., v.85, 1-6, e0232016, 2018 RESUMO: Objetivando determinar a prevalência de anticorpos anti-Trypanosoma vivax e os possíveis fatores de risco associados à infecção em bovinos no estado do Rio Grande do Norte, nordeste do Brasil, o trabalho consistiu em um estudo epidemiológico transversal, com amostragem não probabilística por conveniência, no qual foram analisadas, por meio da reação de imunofluorescência indireta, 467 amostras de soro sanguíneo de bovinos. Das amostras testadas, 42 foram reagentes para anticorpos IgG anti-Trypanosoma vivax, o que correspondeu à prevalência de 9,0%. Os fatores de risco que influenciaram a ocorrência da tripanossomose foram: exploração com finalidade do tipo leite, criação de bovinos de raça europeia, categoria animal vaca em lactação, aquisição de animais, forrageamento das margens de açudes e rios, além da presença de vetores mecânicos. A alta prevalência encontrada em animais de corte (59,5%), fêmeas (95,2%), raça europeia (88,1%), vacas em lactação (85,7%), pastagem a margens de açudes e rios (95,2%), além da presença de vetores mecânicos (81%) e aquisição de animais (88,1%), indica a expansão da tripanossomose no semiárido do Nordeste, e as informações obtidas poderão esclarecer os fatores epidemiológicos que determinam a ocorrência da tripanossomose por T. vivax na região.

Alterações patológicas do sistema genital de cutias (Dasyprocta aguti Linnaeus, 1758) fêmeas criadas em cativeiro

This paper presents seven distinct reports diseases with reproductive origins that are not yet described in females agoutis (Dasyprocta aguti Linnaeus, 1758), affecting fertility or resulted in the animals death. The nature, location and frequency of macroscopic and histological pathological changes of the organs that compose the reproductive system of female agoutis, created under conditions of captivity in the semiarid region of Brazil, are described in this article. Were evaluated by pathological examination of the reproductive tract of thirty-nine naturally dead agoutis and sent to the Veterinary Pathology Laboratory in February 2010 to May 2015. From these, it was found pathological alterations in the reproductive system of 10 (25.6%). A total of 13 abnormalities were observed, and in some animals had the coexistence of more than one alteration. Thus, the pathological changes were: endometritis (n=4, 30.8%), pyometra (n=3; 23%), retained placenta (n=2; 15.4%), fetal maceration (n=1, 7.7%), fetal mummification (n=1, 7.7%), dystocia (n=1, 7.7%) and afuncionais ovary (n=1, 7.7%).

Teste in vitro da eficácia da cipermetrina e amitraz sobre Rhipicephalus sanguineus (Acari: Ixodidae) no Rio Grande do Norte, Brasil

The Rhipicephalus sanguineus is an ectoparasite that infests dogs. Features importance due to transmission of various pathogens. The control of the tick is based on acaricides, and the main active principles resistance has been observed. The aim of this work was to verify the efficacy of amitraz 12.5% and cypermethrin 5% on teleógenas R. sanguineus. We collected 90 teleógenas in dogs in the city of Mossoró, Rio Grande do Norte. Products acaricides were diluted according to the manufacturers recommendation. The engorged females suffered immersion bath for five minutes, then were acondicionas in petri dishes, inspected daily and maintained in environments with average ANDRE, W.P.P. et al. Teste in vitro da eficácia da cipermetrina e amitraz sobre Rhipicephalus sanguineus (Acari: Ixodidae) no Rio Grande do Norte, Brasil. PUBVET, Londrina, V. 8, N. 1, Ed. 250, Art. 1653, Janeiro, 2014. temperature (30.10o max. and 26.14omin:) and relative humidity (63.34% max and 40.33% min) for 30 days. The group amitraz showed 100% efficacy of inhibiting oviposition teleógenas while cypermethrin obtained efficacy ranging from 0.0 to 88.8 with a mean ± SD of 32.1 ± 48.5, respectively. The amitraz showed the greatest efficacy on teleógenas R. sanguineus from pet dogs in the city of Mossoró, however, it is necessary to adopt measures to educate the proper use of these active principles in order to avoid the occurrence of resistance.
