Anaplasma phagocytophilum is a tick-borne pathogen of domestic horses and the causative agent of equine granulocytic anaplasmosis. This case series describes three confirmed cases of clinical anaplasmosis, and a fourth case of presumptive anaplasmosis in Przewalski's horses ( Equus ferus przewalskii) housed at the Smithsonian Conservation Biology Institute from 2008 to 2014. Clinical signs varied among individuals with affected horses exhibiting lethargy, weakness, pyrexia, hypophagia, reluctance to move, or ataxia. Anaplasmosis cases were confirmed with a combination of identification of neutrophilic inclusions (morulae) on peripheral blood smear, positive polymerase chain reaction (PCR) testing of whole blood, or convalescent titers. All animals recovered after antimicrobial therapy with oxytetracycline. Diagnosis should be made by a combination of clinical signs plus identification of morulae or positive A. phagocytophilum PCR. Treatment is curative using oxytetracyline intramuscularly or intravenously followed by daily therapy with oxytetracyline or minocycline for 14-30 days. The authors recommend that A. phagocytophilum infection be included on any differential list for Przewalski's horses presenting with fever or ataxia within or near an enzootic area.

Anaplasmosis is a tick-borne disease that is primarily caused by the rickettsial bacterium Anaplasma phagocytophilum. Anaplasmosis is a febrile disease with common symptoms, including headaches, fever, and lethargy, but it can cause serious organ failure and even death if left untreated. Human infections are reported annually to the Centers for Disease Control and Prevention (CDC) through the National Notifiable Diseases Surveillance System (NNDSS). This report analyzed the cases of anaplasmosis reported by the NNDSS from 2012 to 2016. In total, there were 15,778 reported A. phagocytophilum infections, and the incidence rate was 7.27 cases per million persons per year, with the number of reported cases increasing each year. The demographic group most affected was middle-aged and elderly white males. Infections were most abundant in the coastal northeast and northern midwest regions. Our study provides useful results for a basic understanding of incidence, distribution, and severity of A. phagocytophilum infections.

Anaplasmosis and theileriosis are important diseases with great economic impact that affect the cattle industry worldwide. In this study, we describe the first molecularly confirmed clinical cases of anaplasmosis caused by Anaplasma marginale and of a concurrent infection with A. bovis and Theileria orientalis in Croatian cattle. Clinical signs of A. marginale-infected cows included fever, lethargy, dark urine, as well as icteric and reddish mucous membranes. Postmortem examination revealed icterus, urinary bladder filled with dark urine and splenomegaly. A marginale was observed within erythrocytes on Giemsa-stained spleen imprints. Three affected cows were successfully treated with oxytetracycline, after which no new deaths occurred in the herd. Three cows in a different herd died suddenly and were found to be concurrently infected with A. bovis and T. orientalis. Postmortem examination revealed generalized icterus and urinary bladder filled with dark urine. These cases of A. marginale, A. bovis and T. orientalis infection show that bovine anaplasmosis and theileriosis are present within Croatian cattle and should be included in differential diagnostic protocols.
