AbstractFull Text

Epizootiological study of Anaplasma marginale in regions that contain various reservoir hosts, co-existence of rickettsia pathogens, and common vectors is a complicated task. To achieve diagnosis of this rickettsia in cattle and campeiro deer of Brazilian Pantanal, a comparison was made between a...

Abstract

Data on the world-wide distribution of bovine immunodeficiency virus (BIV) and bovine leukaemia virus (BLV) is limited. A prevalence study of antibodies to BIV and BLV was conducted in 6 different cattle herds maintained in different farms in Rio Grande do Sul and Mato Grosso do Sul in Brazil. Out...

Abstract

A study was conducted to evaluate the use of the polymerase chain reaction (PCR) in the differential diagnosis of T. vivax isolates from cattle in Brazil. Results showed that both conventional PCR and RFLP (restriction fragment length polymorphism)-PCR could differentiate between T. vivax and T....

Abstract

The seroprevalence of Anaplasma marginale among dairy cattle in Goînia, Goias, Brazil, using indirect fluorescent antibody test (IFAT) and ELISA, was determined through an experimental study [date not given]. The map of the area was divided into 47 squares , from which 25 were chosen to be visited...

Abstract

Seroprevalence of antibodies against Anaplasma marginale were studied using an indirect ELISA. Serum samples from 223 cattle from 8 municipalities in the Médio Paraíba mesoregion in the state of Rio de Janeiro, Brazil, were analysed. 98.21% of the samples were positive: 36.32% had a titre of 1:500, ...

Abstract

The cattle parasitic tristeza (TPB; Texas Fever), caused by Babesia bovis, B. bigemina, and Anaplasma marginale, has been known since the end of the 19th century. Preimmunization (infection/treatment) has been used since the beginning of the 20th century as a prophylactic method. In the 60s and...

Abstract

A serological survey was conducted to determine the prevalence of IgG antibodies against B. bovis and B. bigemina. 2018 sera from four municipalities in Rio de Janeiro were collected and analysed by the indirect fluorescent antibodies technique (IFAT). Overall, 82.11 and 94.03% were positive. 83...

Abstract

Indirect enzyme-linked immunosorbent assays (ELISAs) based on recombinant MSP1a and MSP2 from a Brazilian isolate of Anaplasma marginale were developed for detecting antibodies against this rickettsia in cattle. The high sensitivities (99% for both tests) and specificities (100% for both tests)...
