Abstract
Ticks play a pivotal role in propagating a diverse spectrum of infectious agents that detrimentally affect the health of both humans and animals. In the present study, a molecular survey was executed of piroplasmids in ticks collected from small ruminants in four districts within Konya province, Turkey. Microscopic examination identified 1281 adult ticks, which were categorized into 357 pools based on their species, sexes, host animals, and collection site before DNA extraction. The infection rates were calculated by using a maximum likelihood estimate (MLE) with 95% confidence intervals (CI). Hyalomma detritum, H. excavatum, Rhipicephalus bursa, R. sanguineus, and R. turanicus were identified in this study. Among the five tick species identified here, R. turanicus exhibited the highest infestation rate in both goats and sheep. The presence of Babesia ovis and Theileria ovis based on 18S rRNA was confirmed using molecular assay. The overall MLE of infection rates for B. ovis and T. ovis was 2.49% (CI 1.72-3.46) and 1.46% (CI 0.87-2.23), respectively. The MLE of B. ovis and T. ovis infection rates in R. bursa was 10.80% (CI 7.43-14.90) and 0.33% (CI 0.02-1.42), respectively, while that in R. turanicus was 0.12% (CI 0.01-0.51) and 2.08% (CI 1.25-3.22). This study further confirms that R. turanicus and R. sanguineus can act as vectors for B. ovis, thus advancing our comprehension of tick-borne piroplasmids epidemiology and providing valuable insights for the development of effective control strategies for ticks and tick-borne diseases in Turkey.

Abstract
Bats (Mammalia, Chiroptera) represent the second largest group of mammals. Due to their ability to fly and adapt and colonize different niches, bats act as reservoirs of several potentially zoonotic pathogens. In this context, the present work aimed to investigate, using molecular techniques, the occurrence of blood-borne agents (Anaplasmataceae, Coxiella burnetii, hemoplasmas, hemosporidians and piroplasmids) in 198 vampire bats sampled in different regions of Brazil and belonging to the species Desmodus rotundus (n=159), Diphylla ecaudata (n=31) and Diaemus youngii (n=8). All vampire bats liver samples were negative in PCR assays for Ehrlichia spp., Anaplasma spp., piroplasmids, hemosporidians and Coxiella burnetii. However, Neorickettsia sp. was detected in liver samples of 1.51% (3/198) through nested PCR based on the 16S rRNA gene in D. rotundus and D. ecaudata. This is the first study to report Neorickettsia sp. in vampire bats. Hemoplasmas were detected in 6.06% (12/198) of the liver samples using a PCR based on the 16S rRNA gene. The two 16S rRNA sequences obtained from hemoplasmas were closely related to sequences previously identified in vampire and non-hematophagous bats from Belize, Peru and Brazil. The genotypic analysis identified a high diversity of bat-associated hemoplasma genotypes from different regions of the world, emphasizing the need for studies on this subject, in order to better understand the mechanisms of co-evolution between this group of bacteria and their vertebrate hosts. The role of neotropical bat-associated Neorickettsia sp. and bats from Brazilian in the biological cycle of such agent warrant further investigation.

Abstract
Haemoparasites of the genus Babesia infect a wide range of domestic and wild animals. Feline babesiosis is considered endemic in South Africa, while data on Babesia spp. infection in felids in Europe is scarce. Using samples from 51 wild felids, 44 Felis silvestris and 7 Lynx lynx, the study aimed to determine the presence and genetic diversity of Babesia spp. in wild felids in Romania by analyzing the 18S rDNA and two mitochondrial markers, cytochrome b (Cytb) and cytochrome c oxidase subunit I (COI) genes. By 18S rDNA analyses, Babesia spp. DNA was detected in 20 European wild felids. All sequences showed 100% similarity to B. canis by BLAST analysis. Conversely, Cytb and COI analyses revealed the presence of two Babesia spp., B. pisicii n. sp., which we herein describe, and B. canis. The pairwise comparison of both mitochondrial genes of B. pisicii n. sp. showed a genetic distance of at least 10.3% from the most closely related species, B. rossi. Phylogenetic analyses of Cytb and COI genes revealed that B. pisicii n. sp. is related to the so-called “large” canid-associated Babesia species forming a separate subclade in a sister position to B. rossi.

Abstract
N-glycosylation has remained mostly unexplored in Piroplasmida, an order of tick-transmitted pathogens of veterinary and medical relevance. Analysis of 11 piroplasmid genomes revealed three distinct scenarios regarding N-glycosylation: Babesia sensu stricto (s.s.) species add one or two N-acetylglucosamine (NAcGlc) molecules to proteins; Theileria equi and Cytauxzoon felis add (NAcGlc)2-mannose, while B. microti and Theileria s.s. synthesize dolichol-P-P-NAcGlc and dolichol-P-P-(NAcGlc)2 without subsequent transfer to proteins. All piroplasmids possess the gene complement needed for the synthesis of the N-glycosylation substrates, dolichol-P and sugar nucleotides. The oligosaccharyl transferase of Babesia species, T. equi and C. felis, is predicted to be composed of only two subunits, STT3 and Ost1. Occurrence of short N-glycans in B. bovis merozoites was experimentally demonstrated by fluorescence microscopy using a NAcGlc-specific lectin. In vitro growth of B. bovis was significantly impaired by tunicamycin, an inhibitor of N-glycosylation, indicating a relevant role for N-glycosylation in this pathogen. Finally, genes coding for N-glycosylation enzymes and substrate biosynthesis are transcribed in B. bovis blood and tick stages, suggesting that this pathway is biologically relevant throughout the parasite life cycle. Elucidation of the role/s exerted by N-glycans will increase our understanding of these successful parasites, for which improved control measures are needed.

Abstract
Camels ( Camelus dromedarius) are important, multipurpose local animals in Iran. Despite their importance, camelid parasitic diseases have not received adequate attention in the veterinary literature. The present study investigated the prevalence of, and molecularly identified, camel piroplasms in Iran. Blood samples from 248 camels from five different regions of Iran were screened for the presence of piroplasmid infection using an 18SrRNA polymerase chain reaction (PCR) sequencing method. Of the 248 samples, 16 were positive for piroplasms via PCR (6.45%). Ten PCR amplicons with expected sizes were sequenced for molecular characterization. Three camels were infected with Babesia caballi and seven with Theileria equi. Statistical analysis showed that age, sex, and location were not risk factors for infection with piroplasmids in camels.

Abstract
Piroplasmid parasites comprising of Babesia, Theileria, and Cytauxzoon are transmitted by ticks to farm and pet animals and have a significant impact on livestock industries and animal health in tropical and subtropical regions worldwide. In addition, diverse Babesia spp. infect humans as opportunistic hosts. Molecular phylogeny has demonstrated at least six piroplasmid lineages exemplified by B. microti, B. duncani, C. felis, T. equi, Theileria sensu stricto (T. annulata, T. parva, and T. orientalis) and Babesia sensu stricto (B. bovis, B. bigemina, and B. ovis). C1A cysteine-proteinases (C1A-Cp) are papain-like enzymes implicated in pathogenic and vital steps of the parasite life cycle such as nutrition and host cell egress. An expansion of C1A-Cp of T. annulata and T. parva with respect to B. bovis and B. ovis was previously described. In the present work, C1A-Cp paralogs were identified in available genomes of species pertaining to each piroplasmid lineage. Phylogenetic analysis revealed eight C1A-Cp groups. The profile of C1A-Cp paralogs across these groups corroborates and defines the existence of six piroplasmid lineages. C. felis, T. equi and Theileria s.s. each showed characteristic expansions into extensive families of C1A-Cp paralogs in two of the eight groups. Underlying gene duplications have occurred as independent unique evolutionary events that allow distinguishing these three piroplasmid lineages. We hypothesize that C1A-Cp paralog families may be associated with the advent of the schizont stage. Differences in the invertebrate tick host specificity and/or mode of transmission in piroplasmid lineages might also be associated with the observed C1A-Cp paralog profiles.
