Canine babesiosis: autochthonous today, endemic tomorrow?
RECENT reports of autochthonous canine babesiosis in the UK (Cook and others 2016, Phipps and others 2016) suggest that Babesia canis may well become increasingly common in some parts of the country, possibly due to climatic changes that favour its vector (the tick Dermacentor reticulatus) and an increased frequency of international travel among companion animals. While diagnoses of babesiosis in Essex have garnered media attention in recent weeks, these events are of wider significance because they highlight the risk posed by the introduction of tickborne parasites, with at least one case of autochthonous canine ehrlichio...

Minimum infection rate of Ehrlichia minasensis in Rhipicephalus microplus and Amblyomma sculptum ticks in Brazil
This study evaluated the minimum infection rate of E. minasensis in Amblyomma sculptum and R. microplus ticks from locations where naturally infected cattle were previously detected. Overall, 45 engorged R. microplus ticks after molting [43 pools of adults (13.4%), and 2 pools of nymphs (4%)], and 42 engorged females post-oviposition (30.6%) (p=0.008) were positive by PCR for Ehrlichia sp. using the dsb, 16S rRNA and TRP36 genes, making a total of 87 R. microplus samples positive for Ehrlichia spp. (17.1%, IC 95% 14.01-20.75%). The partial sequences generated in the present study were 99-100% similar to the dsb DNA sequenc...

Id: 62: hemophagocytic lymphohistiocytosis caused by infection by ehrlichia chaffeensis: a case report.
We present a case of HLH triggered by severe infection with Ehrlichia chaffeensis in a patient taking methotrexate for seronegative spondyloarthropathy.
A 45-year-old man with a history of ankylosing spondylitis taking methotrexate presented to a community hospital with acute onset of nausea, vomiting and diarrhea. Physical examination revealed a febrile patient with diffuse abdominal tenderness with splenomegaly and diffuse maculopapular rash involving the trunk and all extremities. Labs showed leukopenia and thrombocytopenia. Clinical course was complicated by development of acute renal failure, altered mental status and...

Specifying Pathogen Associations of Amblyomma maculatum (Acari: Ixodidae) in Western Tennessee
The objective was to determine pathogen associations within questing and host-collected A. maculatum, and identify ecological factors associated with pathogen infection that may increase the effectiveness of surveillance methods. Of 265 ticks tested, 60 (22.6%) were infected with R. parkeri, and 15 (5.7%) with Candidatus Rickettsia andeanae, a Rickettsia of unknown pathogenicity. Two deer-collected ticks tested positive for Ehrlichia ewingii. No ticks were positive for Anaplasma or Borrelia species. None of the ecological factors tested (collection month, collection source, sex, and habitat type) were associated with R. pa...

Serological and molecular investigation of Ehrlichia spp. and Anaplasma spp. in ticks and blood of dogs, in the Thrace Region of Turkey
Publication date: Available online 2 March 2016 Source:Ticks and Tick-borne Diseases Author(s): Handan Çetinkaya, Erdal Matur, İbrahim Akyazi, Elif Ergul Ekiz, Levent Aydin, Mufit Toparlak In recent years, tick-borne diseases like ehrlichiosis and anaplasmosis became widespread worldwide threatening the health of both human and companion animals. Therefore, the aim of this study was to determine the presence of Anaplasma spp., and Ehrlichia spp. in dogs and ticks in the Thrace Region of Turkey. A total of 400 blood samples and 912 ticks were collected from dogs living in shelters that are located in four ...

Tick-Borne Illnesses
Tick-borne diseases are prevalent throughout the United States. These illnesses are caused by a variety of different pathogens that use ticks as vectors, including bacteria, viruses, rickettsia, and protozoa. Some of the most common illnesses caused by ticks are Lyme disease, Rocky Mountain spotted fever, babesiosis, ehrlichiosis, anaplasmosis, tularemia, Colorado tick fever, tick-borne relapsing fever, and Powassan disease. Unique skin changes, fever, and influenza-like symptoms may indicate tick-borne disease. Early diagnosis can be difficult as well as nonspecific and can resemble overtraining syndrome. Diagnosis is imp...

Prevalence of antibodies against Ehrlichia spp. and Orientia tsutsugamushi in small mammals around harbors in Taiwan
Conclusions:
The overall prevalence of Ehrlichia spp. and O. tsutsugamushi infections in small mammals active around harbors was 3.28 % and 4.92 %, respectively. The results provided serological evidence supporting the potential risks of transporting pathogens through air and maritime traffic. This study highlights serious issues of the emergence and spread of rickettsial diseases in Taiwan. The incidence of human ehrlichiosis requires further investigation. (Source: Parasites and Vectors)

Growth of Ehrlichia canis, the causative agent of canine monocytic ehrlichiosis, in vector and non-vector ixodid tick cell lines
This study confirms that E. canis, like E. ruminantium, is able to grow not only in cell lines derived from natural and experimental tick vectors but also in a wide range of other cell lines derived from tick species not known to transmit this pathogen. (Source: Ticks and Tick borne Diseases)

Acute phase protein and antioxidant responses in dogs with experimental acute monocytic ehrlichiosis treated with rifampicin
The objective of this study was to investigate the patterns of C-reactive protein (CRP), haptoglobin (Hp), ferritin and paraoxonase-1 (PON-1) during treatment of dogs with acute CME with rifampicin. Blood serum samples from ten Beagle dogs with experimental acute CME were retrospectively examined. Five dogs (Group A) were treated with rifampicin (10mg/Kg/24h), per os, for 3 weeks and 5 dogs (Group B) received no treatment (infected controls). Two Beagle dogs served as uninfected controls. Blood serum samples were serially examined prior to Ehrlichia canis inoculation and on post-inoculation days 14, 21, 28, 35 and 42. Sign...

Vector-Borne Diseases in Stray Dogs in Peninsular Malaysia and Molecular Detection of Anaplasma and Ehrlichia spp. from Rhipicephalus sanguineus (Acari: Ixodidae) Ticks
This study was designed to determine the occurrence of vector-borne pathogens in Malaysian stray dogs using serological and molecular approaches. In total, 48 dog blood samples were subjected to serological analysis using SNAP 4Dx kit (IDEXX Laboratories, Westbrook, ME). The presence of Ehrlichia and Anaplasma DNA in the dog blood samples and Rhipicephalus sanguineus (Latreille) ticks was detected using nested polymerase chain reaction assays. Positive serological findings against Ehrlichia canis and Anaplasma phagocytophilum were obtained in 17 (39.5%) and four (9.3%) of 43 dog samples, respectively. None of the dog blood...

Seroprevalence and Risk Factors of Ehrlichia canis Infection among Companion Dogs of Mashhad, North East of Iran, 2009-2010.
CONCLUSION: This is the first report that describes serological evidences of canine monocytic ehrlichiosis in North-East of Iran. Results suggested that E. canis infection in owned pet dogs from North of Khorasan was not endemic from 2009 to 2010. Additional molecular studies are necessary to confirm E. canis infection and to identify the local strains of the organism.

Butyrylcholinesterase as a marker of inflammation and liver injury in the acute and subclinical phases of canine ehrlichiosis.
Abstract
The aim of this study was to evaluate the role of butyrylcholinesterase (BChE) as a marker of inflammation and liver injury in the acute and subclinical phases of canine ehrlichiosis. Forty-two serum samples of dogs naturally infected with Ehrlichia canis were used, of which 24 were from animals with the acute phase of the disease and 18 with subclinical disease. In addition, sera from 17 healthy dogs were used as negative controls. The hematocrit, BChE activity, hepatic injury (alanine aminotransferase (ALT) and aspartate aminotransferase (AST)), nitric oxide, and cytokines levels were evaluated....
