		Research Hippobosca longipennis - a potential intermediate host of a species of Acanthocheilonema in dogs in northern India Puteri Azaziah Megat Abd Rani, Glen T Coleman, Peter J Irwin, Rebecca J Traub Parasites & Vectors 2011, 4:143 (22 July 2011) Abstract \| Full text \| PDF \| PubMed \| Editor’s summary This study confirmed biological involvement of Hippobosca longipennis for Acanthocheilonema sp. nov.? in northern India and its role as an intermediate host is proposed.Image: A puppy in Ladakh infested with biting fly, Hippobosca longipennis.
		Research A survey of canine tick-borne diseases in India Puteri Azaziah Abd Rani, Peter J Irwin, Glen T Coleman, Mukulesh Gatne, Rebecca J Traub Parasites & Vectors 2011, 4:141 (19 July 2011) Abstract \| Full text \| PDF \| PubMed \| Cited on BioMed Central \| Editor’s summary This study showed most prevalent canine TBD pathogen was Hepatozoon canis, and co-infections between blood pathogens are common in dogs in India.

		Review Fleas as parasites of the family Canidae Gerhard Dobler, Martin Pfeffer Parasites & Vectors 2011, 4:139 (18 July 2011) Abstract \| Full text \| PDF \| PubMed \| Editor’s summary Many different flea species are parasitizing dogs and wild canids world-wide. Many of them can transmit zoonotic bacteria including Yersinia pestis, Rickettsia spp. and Bartonella spp. The growing importance of these pathogens warrants an update of the current literature.

		Review Tick-borne encephalitis virus in dogs - is this an issue? Martin Pfeffer, Gerhard Dobler Parasites & Vectors 2011, 4:59 (13 April 2011) Abstract \| Full text \| PDF \| PubMed \| Editor’s summary Tick-borne encephalitis (TBE) is geographically spreading and emerging in many regions in Eurasia. Dogs are accidental hosts not capable of further spreading TBE virus but they readily seroconvert upon infection. Clinical disease used to be a rare finding but the number such reports is increasing. This warrants an update on the epidemiology, clinical presentation and possible prevention of TBE in the dog. Image: Transmission of TBE virus to a dog via the bite of an Ixodes tick.
		Research Canine leishmaniosis and its relationship to human visceral leishmaniasis in Eastern Uzbekistan Dmitriy A Kovalenko, Shavkat A Razakov, Evgeny N Ponirovsky, Alon Warburg, Rokhat M Nasyrova, Valentina I Ponomareva, Aziza A Fatullaeva, Abdelmajeed Nasereddin, Eyal Klement, Mohammad Z Alam, Lionel F Schnur, Charles L Jaffe, Gabriele Schönian, Gad Baneth Parasites & Vectors 2011, 4:58 (13 April 2011) Abstract \| Full text \| PDF \| PubMed \| Cited on BioMed Central \| Editor’s summary A survey of visceral leishmaniasis in Eastern Uzbekistan revealed a high infection of dogs with a unique strain of Leishmania infantum also found to infect humans in the same region in Central Asia.

		Short report Canine leishmaniasis: the key points for qPCR result interpretation Verónica Martínez, Javier Quilez, Armand Sanchez, Xavier Roura, Olga Francino, Laura Altet Parasites & Vectors 2011, 4:57 (13 April 2011) Abstract \| Full text \| PDF \| PubMed \| Cited on BioMed Central \| Editor’s summary Diagnosis and follow up of CanL is difficult because clinical signs are varied and seroprevalence is high in endemic areas. This study demonstrates the advantages of Leishmania qPCR to diagnose and control CanL, highlights its prognostic value and proposes guidelines for tissue selection and infection monitoring. Image: Blood is a valid tissue for CanL qPCR diagnosis and infection monitoring.
		Research Quantification of Leishmania infantum DNA in females, eggs and larvae of Rhipicephalus sanguineus Filipe Dantas-Torres, Maria Latrofa, Domenico Otranto Parasites & Vectors 2011, 4:56 (13 April 2011) Abstract \| Full text \| PDF \| PubMed \| Cited on BioMed Central \| Editor’s summary Rhipicephalus sanguineus has been considered a putative vector of Leishmania infantum among dogs. In the current study the transovarial passage of L. infantum kinetoplast DNA in field-collected ticks was confirmed by real time PCR. Image: Female R. sanguineus laying thousands of eggs.
		Research Diagnosis of Hepatozoon canis in young dogs by cytology and PCR Domenico Otranto, Filipe Dantas-Torres, Stefania Weigl, Maria Latrofa, Dorothee Stanneck, Donato Decaprariis, Gioia Capelli, Gad Baneth Parasites & Vectors 2011, 4:55 (13 April 2011) Abstract \| Full text \| PDF \| PubMed \| Cited on BioMed Central \| Editor’s summary This study evaluated the best method to achieve a parasitological diagnosis of Hepatozoon canis in a population of receptive young dogs infested by R. sanguineus.

		Review Adhesion and host cell modulation: critical pathogenicity determinants of Bartonella henselae Bettina Franz, Volkhard AJ Kempf Parasites & Vectors 2011, 4:54 (13 April 2011) Abstract \| Full text \| PDF \| PubMed \| Editor’s summary This article reviews known and assumed pathogenicity factors of Bartonella henselae, the aetiological agent of cat scratch disease and vasculoproliferative disorders in humans. Image: The long and hairy surface structures representing Bartonella adhesin A, a trimeric autotransporter adhesin of 240 nm in length.
		Review Major prospects for exploring canine vector borne diseases and novel intervention methods using 'omic technologies Robin B Gasser, Cinzia Cantacessi, Bronwyn E Campbell, Andreas Hofmann, Domenico Otranto Parasites & Vectors 2011, 4:53 (13 April 2011) Abstract \| Full text \| PDF \| PubMed \| Editor’s summary Advances in –omics provides unique opportunities to study neglected canine vector-borne diseases. A profound understanding of these diseases at the molecular level should lead to radically new control methods.

		Research Infectivity to Phlebotomus perniciosus of dogs naturally parasitized with Leishmania infantum after different treatments Guadalupe Miró, Rosa Gálvez, Cristeta Fraile, Miguel A Descalzo, Ricardo Molina Parasites & Vectors 2011, 4:52 (13 April 2011) Abstract \| Full text \| PDF \| PubMed \| Cited on BioMed Central \| Editor’s summary Evaluation through direct xenodiagnosis the infectivity to Phlebotomus perniciosus of dogs naturally parasitized with Leishmania infantum after treatment, and to follow the clinical and parasitic course of disease.

		Review Why is Southern African canine babesiosis so virulent? An evolutionary perspective Barend L Penzhorn Parasites & Vectors 2011, 4:51 (13 April 2011) Abstract \| Full text \| PDF \| PubMed \| Editor’s summary In Southern Africa, canine babesiosis manifests as a highly virulent disease, with even pups and juveniles being severely affected. Babesia rossi, the causative organism, circulates in indigenous African canids, such as jackals and wild dogs. The contention is that domestic dogs, which are not indigenous to Africa, have not yet adapted to B. rossi. Image: Intra-erythrocytic Babesia rossi on a canine blood smear.
		Research Babesiosis due to the canine Babesia microti-like small piroplasm in dogs - first report from Portugal and possible vertical transmission Paula Simões, Luís Cardoso, Manuela Araújo, Yael Yisaschar-Mekuzas, Gad Baneth Parasites & Vectors 2011, 4:50 (13 April 2011) Abstract \| Full text \| PDF \| PubMed \| Cited on BioMed Central \| Editor’s summary Babesia microti-like (syn.
