Description:
Rhipicephalus camicasi Morel, Mouchet et Rodhain, 1976 is thought to be distributed across Africa, Arabian Peninsula and the Mediterranean region. It belongs to the Rhipicephalus sanguineus (Latreille, 1806) species complex. Mitochondrial genome sequences are becoming frequently used for the identification and differentiation of tick species. In the present study, the entire mitochondrial genome of R. cf. camicasi (~15 kb) collected from a camel in Saudi Arabia was sequenced and compared with mitogenomes of two species of Rhipicephalus Koch, 1844. The mitochondrial genome is 87.8% and 91.7% identical to the reference genome of R. sanguineus (sensu stricto, former "temperate lineage") and Rhipicephalus linnaei (Audouin, 1826) (former "tropical lineage"). The current study delivers a molecular reference for material that resembles R. camicasi. We propose to consider the current material, including the complete mitogenome, as the reference for R. camicasi, until a revision using topotypical material is available.

Description:
To investigate the transmission of species of Cryptosporidium Tyzzer, 1907 in Timis County, Romania, 48 isolates of Cryptosporidium coccidia from 11 children, 29 calves and eight pigs were characterised by molecular analysis of two loci (SSU rRNA and 60-kDa glycoprotein gene). Overall, 22 isolates were amplified and sequence analyses revealed that all isolates were Cryptosporidium parvum Tyzzer, 1912. Two subtype families were identified, IIa and IId. Subtype IIdA22G1 (n = 4) was the single C. parvum subtype found in children. Subtypes found in calves included IIdA27G1 (n = 8), a novel subtype, IIdA25G1 (n = 5), IIdA22G1 (n = 2), IIdA21G1a (n = 1), and IIaA16G1R1 (n = 1). Subtype IIdA26G1 was found in a pig. These results were significantly different from previous Romanian reports, as the five subtypes of family IId identified in this study were never identified previously in this country. Thus, cattle may be a source of Cryptosporidium infections for humans and the transmission dynamics of C. parvum in Romania is more complex than previously believed., Patrícia Manuela Vieira, Narcisa Mederle, Maria Luísa Lobo, Kálmán Imre, Ovidiu Mederle, Lihua Xiao, Gheorghe Darabus, Olga Matos., and Obsahuje bibliografii

Description:
We report the molecular-phylogenetic identification of larvae of the nematode genus Gnathostoma Owen, 1836 collected from a snake, Ptyas koros Schlegel, in Laos and adult worms from the stomach of a dog in Thailand. DNA was extracted and amplified targeting the partial cox1 gene and the ITS-2 region of ribosomal DNA. Phylogenetic analyses indicated that all five advanced third-stage larvae and seven adult worms were Gnathostoma spinigerum Owen, 1836. This is also the first molecular evidence of infection with G. spinigerum in a snake from Laos., Jurairat Jongthawin, Pewpan M.

Description:
Species of Hepatozoon Miller, 1908 are vector-borne parasites that infect domestic and wild animals worldwide. Hepatozoon ursi Kubo, Uni, Agatsuma, Nagataki, Panciera et al., 2008 was reported from bears (Ursidae) in Japan and India. The present study represents the first report of infection with H. ursi in Turkish brown bears (Ursus arctos Linnaeus) by microscopic and molecular analysis. Two dead brown bears were found in Uzundere and Pasinler districts of Erzurum. Blood and visceral organ (spleen and liver) samples were delivered to laboratory by the Nature Conservation and National Parks officers. Detected gamonts were evaluated based on morphological features and confirmed as gamonts of H. ursi. The size of gamonts and parasitemia were 8.2 × 3.5 μm (6.9-8.7 × 3.0-3.9 μm; n = 12) and 0.6% (6/1000 leukocytes), respectively. The blood and visceral organ samples were positive for species of Hepatozoon by PCR targeting partial sequence of 18S rDNA. Sequence analysis of newly obtained sequences of H. ursi showed 98.8-100% identity with previously sequenced isolates of H. ursi. Sequences of H. ursi from Erzurum were identical to each other and showed 100% identity with isolates of H. ursi from ticks Ixodes ricinus (Linnaeus), Rhipicephalus turanicus Pomerantzev and Hyalomma marginatum Koch collected from two brown bears in Turkey (GenBank accession numbers MN463021, MN463022, MN905023). Analysis of partial sequences of the 18S rRNA gene of H. ursi showed that Turkish isolates differ in NT substitutions found at three different positions [72 (A→G), 537 (A→G) and 570 (A→T)]. This study provides morphological and molecular data of H. ursi infection in brown bears from two districts of Erzurum, Turkey. Further studies are needed to elucidate whether brown bears have any eco-epidemiologic importance in the life cycle of H. ursi in wildlife.

20. Putative intranuclear coccidium in Mauremys leprosa (Schweigger) from Morocco

Subject:
Coccidia, freshwater turtles, and 18s rRNA
Language:
English
Description:
Although intranuclear coccidiosis was first identified in chelonians less than 30 years ago, it is now considered an important emerging disease. Symptoms include anorexia, weakness and weight loss, potentially leading to death of the infected animal. The use of molecular tools has led to improved diagnosis and has also led to an increase in known host species. Here we report a putative intranuclear coccidium in Mauremys leprosa (Schweigger), from Morocco, based on 18S rDNA sequence analysis. This is, to the best of our knowledge, the first report of this parasite from a freshwater terrapin species.
