| As Rocky Mountain Spotted Fever is the most common tick-borne disease in South America, the presence of Rickettsia sp. in Amblyomma ticks is a possible indication of its endemicity in certain geographic regions. In the present work, bacterial DNA sequences related to Rickettsia amblyommii genes in A. dubitatum ticks, collected in the Brazilian state of Mato Grosso, were discovered. Simultaneously, Paracoccus sp. was detected in aproximately 77% of A. cajennense specimens collected in Rio de Janeiro, Brazil. This is the first report of Paracoccus sp. infection in a specific tick population, and raises the possibility of these bacteria being maintained and/or transmitted by ticks. Whether Paracoccus sp. represents another group of pathogenic Rhodobacteraceae... |

| ABSTRACT: The Wildlife Screening Center (CETAS) of the Tietê Ecological Park (PET), situated at the municipality of São Paulo, receives, treats and rehabilitates wild animals that have been dislodged from their natural environment due to different reasons. This study analyzed the ixodid fauna, and the rickettsial infection in these ticks, collected on wild animals received at the PET’s CETAS. During the period from March 2003 to November 2016, 936 ticks were collected from 96 wild animals (16 bird and 18 mammal species) that were sent to CETAS. The following 12 ixodid species were identified: Amblyomma aureolatum, Amblyomma brasiliense, Amblyomma calcaratum, Amblyomma dubitatum, Amblyomma longirostre, Amblyomma ovale, Amblyomma parkeri, Amblyomma sculptum,... |

| The hemocyte composition of adults of Amblyomma cajennense (Fabricius, 1787) Koch, 1844 adults consisted of three basic cellular types: prahemocyte I (PR I), plasmatocyte (PL) and spherulocyte (ES II). Among the ixodids observed (A. cajennense; A. dissimile Koch, 1844; Rhipicephalus sanguineus Latreille, 1806; Anocentor nitens (Neumann, 1897) Schulze, 1937; Boophilus microplus Canestrini, 1887 and Haemaphysalis sp.) only A. cajennense was different in the adult hemolymph colour. It changed from amber to deep blue as the ixodid age advanced. This fact could be associated with the presence of hemocyanin in the hemolymph and points out the need to develop further investigations about the Ixodidae hemolymph pratein composition as well as the function of all... |

| Information on autochthonous ticks and their hosts is scarce in South America, especially in Argentina. To contribute to tick knowledge in the region, 2094 ticks were collected from the vegetation, humans, domestic and wild animals at a host-and-tick rich area of northern Argentina during six field trips conducted in 1999 (January and August), 2000 (March and November), and 2001 (March and June). The ticks were identified as Amblyomma cajennense (Fabricius), Amblyomma coelebs Neumann, Amblyomma sp., Haemaphysalis juxtakochi Cooley, H. leporispalustris (Packard), Ixodes pararicinus Keirans & Clifford, I. loricatus Neumann, I. longiscutatum Boero and Ixodes sp. Small mammals were mainly parasitized by immature stages of Ixodes; humans and domestic... |

| El análisis de una colección de garrapatas de mamíferos del noroeste argentino, depositados en la Colección de Anexos de la Colección Mamíferos Lillo (CML) de la Universidad Nacional de Tucumán, permitió ampliar el área de distribución de Ixodes luciae Sénevet, a las provincias de Salta y Tucumán e incrementar su rango de huéspedes al roedor sigmodontino Calomys callosus (Rengger) y a los marsupiales de la familia Didelphidae Micoureus constantiae (Thomas), Thylamys cinderella Thomas y Thylamys venustus (Thomas). Se registró a C . callosus y Oligoryzomys destructor (Tschudi) como nuevos huéspedes de Ixodes pararicinus Keirans & Clifford, y a los Carnivora Lycalopex gymnocercus (Fischer) y Oncifelis geoffroyi (d´Orbigny & Gervais)... |

| Un perro Bloodhound macho de 3 años de edad fue remitido a una clínica particular de Ciudad Victoria, Tamaulipas, México, con historia de pérdida de peso, debilidad generalizada, anorexia y ptialismo de 2 semanas de evolución. Los resultados del hemograma revelaron una anemia moderada y leucograma con inflamación crónica. Además, se observó que 10% de neutrófilos contenían en su citoplasma pequeñas estructuras de forma alongada de color azul pálido, compatibles con gametocitos de Hepatozoon spp. Hasta ahora, éste es el primer caso de hepatozoonosis canina detectada en Tamaulipas. |

| There are only 33 records of rodents of the subfamily Caviinae Fischer de Waldheim, 1817 (Hystricognathi: Caviidae) infested by hard ticks in South America, where the subfamily is established. Caviinae is formed by three genera: Cavia Pallas, 1766, Galea Meyen, 1833 and Microcavia Gervais and Ameghino, 1880. Records of Amblyomma pictum Neumann, 1906, A. dissimile Koch, 1844 and A. pseudoparvum Guglielmone, Keirans and Mangold, 1990 are considered doubtful. Bona fide records are all for localities south of the Amazonian basin in Argentina, Bolivia, Uruguay and Brazil. Thirteen records are for A. tigrinum Koch, 1844, four for A. triste Koch, 1844, three for A. parvum Aragão, 1908 (larvae and nymphs of these three species), one for A. cajennense (Fabricius,... |

| Diseases transmitted by ticks have been an important health problem all over the world. Brazilian Spotted Fever (BSF) stands for a serious epidemiological concern due to the high mortality rates pointed out. Capybaras are commonly incriminated as possible reservoirs in the BSF transmission cycle. In the last decades the numbers of these animals raised sharply and they have invaded human areas. They intensify the contact between ticks and humans beings. This study aim is to contribute to the possible role performed for this rodent in the BSF epidemiology in some areas located in Campinas region, São Paulo. Cabybaras infected by rickettsiae of BSF group were studied through the analysis of the frequencies of BSF-group rickettisae antibodies titer = 64 by... |

| ABSTRACT: Ticks are known worldwide for parasitizing a number of wild hosts. However, few studies have been conducted on ticks in zoos in Brazil. The objective of the present study was to collect, identify, and report the parasitic tick fauna found on wild Amazon animals received and attended at the Santarém Zoological Park from September 2004 to September 2013. In all, 56 animals, including 26 mammals and 30 reptiles, were sampled, from which 1172 ticks were collected and identified, comprising 862 adults, 284 nymphs, and 26 larvae. Nymphs of Amblyomma geayi on three-toed sloth (Bradypus tridactylus), adults of Amblyomma longirostre on black dwarf porcupine (Coendou nycthemera), and nymphs of Amblyomma naponense on southern tamandua (Tamandua... |
