“…(Laha et al, 2014) reported higher prevalence (56%) of canine babesiosis which might be due to the reason that (Laha et al, 2014) studied molecular prevalence of canine babesiosis, while microscopy was used in the present study which is less sensitive comparatively. Prevalence of anaplasmosis in the present study was found similar with the findings of (Pennisi et al, 2012) who reported 38% prevalence of anaplasma. Findings of (Bhattacharjee and Sarmah, 2013) are not in agreement with current study and the possible reasons may be that (Bhattacharjee and Sarmah, 2013) reported only Anaplasma platys and did not reported Anaplasma phagocythophilum.…”

| Dog (Canine lupus familiaris) is one of the most neglected specie in the research institutes in Pakistan. Humans are at great risk of zoonotic diseases due to close association with dogs and humans-dog interspecies bond is at danger due to these diseases. The aim of the study was to determine the haemo-parasitic diseases of dogs, its effect on hematological profile and to correlate it with general health status of dogs. Total of 121 blood samples were collected from district Peshawar and Charsadda from public and private sectors including armed forces. Microscopic results showed 34 and 19% prevalence of anaplasmosis and canine babesiosis, respectively. Prevalence of haemo-parasitic diseases in dogs were studied with respect to different risk factors i.e. season, location, breed, owner, sex and age. Statistically significant (P<0.05) relation was recorded with respect to season, breed, ownership and age while no significant (P>0.05) relation was observed with respect to location and sex. Anemia was striking feature in hematological parameters with significant (P<0.01) decrease in red blood cells, hemoglobin and hematocrit values and can be classified as normocytic hypochromic with significant decrease (P<0.01) in Mean corpuscular hemoglobin concentration (MCHC). Ticks are important vector for the transmission of the haemo-parasites and ticks infestation is favored by hot and humid environment, the reason for higher prevalence of haemo-parasites in the summer season. Awareness among the community should be initiated through media talks, print and electronic media for periodical screening of their dogs for haemo-parasitic diseases and along with that control strategies should be designed.

“…Such, a prevalence of infection of B. canis in southern Italy most likely indicates the failure of serological tests in differentiating anti- B. canis and B. vogeli specific antibodies [42, 43]. Although in previous studies the occurrence of ticks on hosts has never been investigated thoroughly [21, 41], it is known that R. sanguineus ( s.l . ), the vector of B. vogeli , is the most frequently retrieved tick species but not D. reticulatus [20, 44].…”

BackgroundTwo clustered clinical cases of canine babesiosis were diagnosed by veterinary practitioners in two areas of northeastern Italy close to natural parks. This study aimed to determine the seroprevalence of babesial infection in dogs, the etiological agents that cause canine babesiosis and the potential tick vector for the involved Babesia spp.MethodsThe study area was represented by two parks in northeastern Italy: Groane Regional Park (Site A) and the Ticino Valley Lombard Park (Site B). From March to May 2015 ticks were collected from the vegetation in three transects in each site. In the same period, blood samples were collected from 80 dogs randomly chosen from veterinary clinics and kennel located in the two areas. Morphological identification of the ticks was performed and six specimens were molecularly characterised by the amplification and sequencing of partial mitochondrial 12S rRNA, 16S rRNA and cox1 genes. For phylogenetic analyses, sequences herein obtained for all genes and those available from GenBank for other Dermacentor spp. were included. Dog serum samples were analysed with a commercial indirect fluorescent antibody test to detect the presence of IgG antibodies against Babesia canis. Ticks and blood samples were tested by PCR amplification using primers targeting 18S rRNA gene of Babesia spp.ResultsTicks collected (n = 34) were morphologically identified as adults of D. reticulatus. Twenty-eight ticks were found in all transects from Site A and the remaining six were collected in Site B. Blast analysis of mitochondrial sequences confirmed the morphological identification of processed tick specimens by revealing a highest nucleotide similarity (99–100 %) with those of D. reticulatus available in the GenBank database. The phylogenetic trees were concordant in clustering D. reticulatus in a monophyletic clade. Seven dogs (8.8 %) had antibodies against B. canis, most of which (n = 6) came from Site A. Analysis of nucleotide sequences obtained from one tick and from one dog identified B. canis displayed a 100 % similarity to those available in GenBank.ConclusionsThis study morphologically and molecularly confirms the presence of D. reticulatus in Italy and links it, for the first time, with the occurrence of B. canis infection in dogs in this country.

Update on Tick-Borne Rickettsioses around the World: a Geographic Approach

SUMMARY Tick-borne rickettsioses are caused by obligate intracellular bacteria belonging to the spotted fever group of the genus Rickettsia . These zoonoses are among the oldest known vector-borne diseases. However, in the past 25 years, the scope and importance of the recognized tick-associated rickettsial pathogens have increased dramatically, making this complex of diseases an ideal paradigm for the understanding of emerging and reemerging infections. Several species of tick-borne rickettsiae that were considered nonpathogenic for decades are now associated with human infections, and novel Rickettsia species of undetermined pathogenicity continue to be detected in or isolated from ticks around the world. This remarkable expansion of information has been driven largely by the use of molecular techniques that have facilitated the identification of novel and previously recognized rickettsiae in ticks. New approaches, such as swabbing of eschars to obtain material to be tested by PCR, have emerged in recent years and have played a role in describing emerging tick-borne rickettsioses. Here, we present the current knowledge on tick-borne rickettsiae and rickettsioses using a geographic approach toward the epidemiology of these diseases.
