Based on the previous report, a traumatic event was assumed. Feed and water intake were unremarkable, the gait was altered due to slight ataxic movements in all 4 limbs. The animal showed no further neurological deficits on initial presentation. Radiographs revealed a displacement of the cervical vertebrae to the left as part of a subluxation of the articular processes of the cervical vertebrae C4 and C5. During the course of conservative treatment with pain medication, neurologic signs including ataxia and I: mpaired balance developed in spite of unremarkable food intake. Subsequently, the animal died at a time when it was not under observation.Pathologic examination revealed degenerative and inflammatory alterations as well as hemorrhages in the cervical medulla at the level of the axial deviation of the cervical spine. Under consideration of the patient's history, the findings may most likely be seen as the result of blunt trauma and represent the cause of the neurologic signs.This is the first case description of a subluxation of the cervical vertebral column in an alpaca in Germany that has been evaluated in detail.</p>","PeriodicalId":23115,"journal":{"name":"Tieraerztliche Praxis Ausgabe Grosstiere Nutztiere","volume":"52 6","pages":"346-351"},"PeriodicalIF":0.4,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142785778","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Changing climatic conditions, however, have meanwhile led to a year-round risk of tick exposure and thus infections with <i>A. phagocytophilum</i>. The presented case report underlines the seasonal peak phase of the infection risk in that the presentation of the horse to the veterinarian occurred in June. Additionally, clinical signs - including fever - are mostly unspecific and thrombocytopenia represents the most significant hematological abnormality. Direct and indirect detection methods are available for the diagnosis of an infection or contact with the pathogen. A positive PCR confirms an acute infection, as in the presented case, while positive antibody levels indicate contact with the pathogen in the (recent) past. Additionally, inclusion bodies, so called morulae, may be detected rapidly and inexpensively in smears derived from the peripheral blood and are predominantly found in neutrophilic granulocytes, less frequently in eosinophilic granulocytes. However, microscopy has a lower sensitivity compared to PCR-testing. In the presented case, morulae could not be detected in EDTA blood despite positive PCR. Antibiotics with intracellular activity, such as oxytetracycline and/or doxycycline are the treatment of choice and, as in the described case, often result in rapid clinical improvement in horses suffering from EGA. The elimination of the pathogen should be confirmed by PCR-testing 5-8 days after the completion of the antibiotic therapy. Whether and how long antibodies against <i>A. phagocytophilum</i> could possibly be protective against reinfection remains unknown.

To this end, 621 references were analyzed. It is evident that the number of publications increased between 2010 and 2020, which emphasizes the importance of the subject.
