Cerebral trypanosomiasis in native cattle
Abstract
During the late rainy season and winter season in 1990, outbreaks of suspected trypanosomiasis in native cattle (Bos indicus) occurred on 13 farms in Petchaboon province, Thailand. Forty-two cattle presented with nervous symptoms including circling, excitation, jumping, aggressive behavior, lateral recumbency, convulsion and finally death. Blood samples from 39 cattle on the two farms in which the outbreaks occurred were collected and examined for the presence of Trypanosoma evansi. It was found that all 16 blood samples from cattle on farm A were positive of T. evansi by mouse inoculation and indirect fluorescent antibody test (IFAT). In cattle from farm B, on the other hand only 37.5% and 39% of the samples were positive by mouse inoculation and IFAT, respectively. T. evansi was detected on impression smears of organs from the three cattle which died with nervous symptoms and also in smears made from their cerebrospinal fluid. In addition, trypanosomes were isolated from the cerebrum, cerebellum, pons and spinal cord by mouse inoculation.

“Strikingly, stress-induced protein kinases could also induce or aggravate auto-immunity by phosphorylating self-antigens to be recognized by auto-antibodies (Utz et al., 1997; Patterson et al., 2014).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
