    The Veterinary record, 2018
    Co-Authors: Charalampos Attipa, Gad Baneth, David Maguire, Laia Solano-gallego, Balazs Szladovits, Emily N. Barker, Alison Farr, Séverine Tasker
    Abstract:

    An increasing number of non-endemic vectorborne pathogens have been described in dogs imported to the UK in the past two decades. Recently, an outbreak of canine babesiosis in south-east England has raised veterinary awareness with regard to the impact of such diseases on the UK canine population. Canine Hepatozoonosis, caused by Hepatozoon canis and transmitted by the ingestion of Rhipicephalus sanguineus ticks, is widespread in the Mediterranean basin. Herein we describe the first three molecularly confirmed clinical cases of canine Hepatozoonosis in dogs imported into the UK. Veterinarians in the UK should be aware of H canis as a potential infection in imported dogs, especially in the face of the expanding distribution of R sanguineus ticks in Europe.

  • transplacental transmission
    2016
    Co-Authors: Gad Baneth, Osnat Eyal, Alina Sheiner, Shelley Hahn, Jean-pierre Beaufils, Yigal Anug, Dalit Talmi-frank
    Abstract:

    Full list of author information is available at the end of the articlefindings on feline Hepatozoonosis and promote the understanding of this infection. The results indicate that feline infection is primarily caused by a morphologically and genetically distinct species, H. felis, which has predilection to infecting muscular tissues, and is highly prevalent in the cat population studied. The lack of previous comprehensively integrated data merits the redescription of this parasite elucidating its parasitological characteristics

  • Canine vector-borne co-infections: Ehrlichia canis and Hepatozoon canis in the same host monocytes.
    Veterinary parasitology, 2014
    Co-Authors: Gad Baneth, Shimon Harrus, Arnon Gal, Itamar Aroch
    Abstract:

    The protozoon Hepatozoon canis and the rickettsia Ehrlichia canis are tick-borne pathogens, transmitted by Rhipicephalus sanguineus, which cause canine Hepatozoonosis and canine monocytic ehrlichiosis, respectively. Co-infection of the same host monocytes with H. canis and E. canis confirmed by molecular characterization of the infecting agents and quantitative assessment of co-infected cells is described for the first time in three naturally-infected dogs. Blood smear evaluation indicated that at least 50% of the leukocytes infected with H. canis gamonts contained E. canis morulae. Co-infection of the same host cell demonstrated in this report suggests that infection with one pathogen may permit or enhance invasion or prolonged cellular survival of the other.

  • Prevalence and molecular characterization of Hepatozoon canis in dogs from urban and rural areas in Southeast Brazil.
    Research in veterinary science, 2014
    Co-Authors: R.l. De Miranda, Antonio Vicente Mundim, Osnat Eyal, Marcia Cristina Cury, Lucia Helena O’dwyer, J.r. De Castro, Betina Metzger, Adriano Stefani Rubini, Dalit Talmi-frank, Gad Baneth
    Abstract:

    Abstract The objective of this survey was to investigate the prevalence of Hepatozoon infection in dogs in the rural and urban areas of Uberlândia, Brazil by PCR and molecular characterization. DNA was obtained from blood samples collected from 346 local dogs from both genders and various ages. Seventeen PCR products from positive blood samples of urban dogs and 13 from the rural dogs were sequenced. Partial sequences of the 18S rRNA gene indicated that all 30 dogs were infected with Hepatozoon canis similar in sequence to H. canis from southern Europe. Four local dog sequences were submitted to GenBank (accessions JN835188; KF692038; KF692039; KF692040). This study indicates that H. canis is the cause of canine Hepatozoonosis in Uberlândia and that infection is similarly widespread in rural and urban dogs.

  • Molecular and histopathological detection of Hepatozoon canis in red foxes (Vulpes vulpes) from Portugal
    Parasites & vectors, 2014
    Co-Authors: Luís Cardoso, Osnat Eyal, Helder Cortes, Antónia Reis, Ana Patrícia Lopes, Maria João Vila-viçosa, Paula Rodrigues, Gad Baneth
    Abstract:

    Background Hepatozoon canis is a protozoan tick-borne pathogen of dogs and wild canids. Hepatozoon spp. have been reported to infect foxes in different continents and recent studies have mostly used the polymerase chain reaction (PCR) for the detection and characterization of the infecting species. Surveying red foxes (Vulpes vulpes) may contribute to better understanding the epidemiology of canine vector-borne diseases, including Hepatozoonosis caused by H. canis in domestic dogs. The present study investigated the prevalence of Hepatozoon spp. by means of histopathology and molecular analysis of different tissues in red foxes from different parts of Portugal.

  • Redescription of Hepatozoon felis (Apicomplexa: Hepatozoidae) based on phylogenetic analysis, tissue and blood form morphology, and possible transplacental transmission
    Parasites & Vectors, 2013
    Co-Authors: Gad Baneth, Osnat Eyal, Alina Sheiner, Shelley Hahn, Jean-pierre Beaufils, Yigal Anug, Dalit Talmi-frank
    Abstract:

    Background A Hepatozoon parasite was initially reported from a cat in India in 1908 and named Leucocytozoon felis domestici . Although domestic feline Hepatozoonosis has since been recorded from Europe, Africa, Asia and America, its description, classification and pathogenesis have remained vague and the distinction between different species of Hepatozoon infecting domestic and wild carnivores has been unclear. The aim of this study was to carry out a survey on domestic feline Hepatozoonosis and characterize it morphologically and genetically. Methods Hepatozoon sp. DNA was amplified by PCR from the blood of 55 of 152 (36%) surveyed cats in Israel and from all blood samples of an additional 19 cats detected as parasitemic by microscopy during routine hematologic examinations. Hepatozoon sp. forms were also characterized from tissues of naturally infected cats. Results DNA sequencing determined that all cats were infected with Hepatozoon felis except for two infected by Hepatozoon canis . A significant association (p = 0.00001) was found between outdoor access and H. felis infection. H. felis meronts containing merozoites were characterized morphologically from skeletal muscles, myocardium and lungs of H. felis PCR-positive cat tissues and development from early to mature meront was described. Distinctly-shaped gamonts were observed and measured from the blood of these H. felis infected cats. Two fetuses from H. felis PCR-positive queens were positive by PCR from fetal tissue including the lung and amniotic fluid, suggesting possible transplacental transmission. Genetic analysis indicated that H. felis DNA sequences from Israeli cats clustered together with the H. felis Spain 1 and Spain 2 sequences. These cat H. felis sequences clustered separately from the feline H. canis sequences, which grouped with Israeli and foreign dog H. canis sequences . H. felis clustered distinctly from Hepatozoon spp. of other mammals. Feline Hepatozoonosis caused by H. felis is mostly sub-clinical as a high proportion of the population is infected with no apparent overt clinical manifestations. Conclusions This study aimed to integrate new histopathologic, hematologic, clinical, epidemiological and genetic findings on feline Hepatozoonosis and promote the understanding of this infection. The results indicate that feline infection is primarily caused by a morphologically and genetically distinct species, H. felis , which has predilection to infecting muscular tissues, and is highly prevalent in the cat population studied. The lack of previous comprehensively integrated data merits the redescription of this parasite elucidating its parasitological characteristics.

  • oocysts of hepatozoon canis in rhipicephalus boophilus microplus collected from a naturally infected dog
    Veterinary Parasitology, 2011
    Co-Authors: Renata Lima De Miranda, Antonio Vicente Mundim, Jacqueline Ribeiro De Castro, Maria Marlene Martins Olegario, Marcelo Emilio Beletti, Lucia Helena Odwyer, Osnat Eyal, Dalit Talmifrank, Marcia Cristina Cury, Gad Baneth
    Abstract:

    Canine Hepatozoonosis is a tick-borne disease caused by protozoans of the genus Hepatozoon. Several tick species have been implicated as potential vectors. Therefore, extensive studies are needed to determine the ‘natural’ endemic cycle of this parasite. This paper presents the first report of the presence of Hepatozoon canis oocysts in Rhipicephalus (Boophilus) microplus collected from an infected dog.

  • A serosurvey of Hepatozoon canis and Ehrlichia canis antibodies in wild red foxes (Vulpes vulpes) from Israel
    Veterinary Parasitology, 2004
    Co-Authors: Zohar Fishman, Shimon Harrus, Liat Gonen, Dalit Strauss-ayali, Roni King, Gad Baneth
    Abstract:

    A seroepidemiological survey was conducted to investigate the prevalence of antibodies reactive with Ehrlichia canis and Hepatozoon canis antigens in free-ranging red foxes (Vulpes vulpes) in Israel. Of 84 fox sera assayed, 36% were seropositive for E. canis by the indirect fluorescent antibody (IFA) test and 24% were positive for H. canis using an enzyme-linked immunosrbent assay (ELISA). Canine ehrlichiosis and Hepatozoonosis appear to be endemic in the wild red fox populations in Israel, and foxes may serve as a reservoir for infection of domestic dogs and other wild canine species.
