This study evaluates the seizure of birds in the state of Amazonas during twenty years (1992-2011), providing information on the sale of birds in a state recognized for its significant biodiversity. We compiled a total of 2,698 seizure records of illegal wildlife trade, which were drawn up and issued by the Brazilian Institute of Environment and Renewable Natural Resources-IBAMA (the Brazilian official agency for environmental license and patrol) in the state of Amazonas, during 240 months. Reports of birds seized were found in only 297 (11%) of the seizure records analyzed. The number of bird specimens ranged from 3 to 710 per year, and the taxonomic richness ranged from 1 to 24 species. Considering all seizures, there was a richness of 40 bird species, distributed in 16 families and 10 orders. Among the families analyzed, Thraupidae was the richest, with 17 species, followed by Psittacidae, with eight species. The order Passeriformes was the most represented, with 12 genera, where Sporophila was the richest, with nine species (22.5% of total species). The Saffron Finch (Sicalis flaveola-Linnaeus, 1766), Muscovy Duck (Cairina moschata-Linnaeus, 1758) and Chestnut-bellied Seed-Finch (Sporophila angolensis-Linnaeus, 1766) together accounted for more than half (56.9%) of the total birds seized for the period. Of the species recorded in this study, five (12.5%) were listed as Endangered. Our results suggest that the illegal trade of animals in Amazonas shows a pattern different from that which has been reported in other Brazilian states. Birds were little represented in the Amazon, and the main reason for their illegal trade was related to their use as food. In addition to the cultural aspects, the richness of vertebrates in the Amazon certainly influences the choice of animals used and marketed in the Amazon region.

The tick fauna of Brazil is currently composed by 72 species. The state of Amazonas is the largest of Brazil, with an area of ≈ 19% of the Brazilian land. Besides its vast geographic area, only 19 tick species have been reported for Amazonas. Herein, lots containing ticks from the state of Amazonas were examined in three major tick collections from Brazil. A total of 5933 tick specimens were examined and recorded, comprising 2693 males, 1247 females, 1509 nymphs, and 484 larvae. These ticks were identified into the following 22 species: Amblyomma cajennense sensu lato, Amblyomma calcaratum, Amblyomma coelebs, Amblyomma dissimile, Amblyomma dubitatum, Amblyomma geayi, Amblyomma goeldii, Amblyomma humerale, Amblyomma latepunctatun, Amblyomma longirostre, Amblyomma naponense, Amblyomma oblongoguttatum, Amblyomma ovale, Amblyomma rotundatum, Amblyomma scalpturatum, Amblyomma varium, Dermacentor nitens, Haemaphysalis juxtakochi, Ixodes cf. Ixodes fuscipes, Ixodes luciae, Rhipicephalus microplus, Rhipicephalus sanguineus sensu lato. Ticks were collected from 17 (27.4%) out of the 62 municipalities that currently compose the state of Amazonas. The following four species are reported for the first time in the state of Amazonas: A. coelebs, A. dubitatum, H. juxtakochi, and Ixodes cf. I. fuscipes. The only tick species previously reported for Amazonas and not found in the present study is Amblyomma parvum. This study provides a great expansion of geographical and host records of ticks for the state of Amazonas, which is now considered to have a tick fauna composed by 23 species. It is noteworthy that we report 1391 Amblyomma nymphs that were identified to 13 different species.

Since its original description from the Amazonian region, the tick species Amblyomma goeldii Neumann, 1899 has been misidentified with Amblyomma rotundatum Koch, 1844 in different countries of the Neotropical region. Because of this, some authors have considered that the only confirmed records of A. goeldii were from French Guyana. Herein, we reviewed all specimens of A. goeldii that have been deposited at two tick collections in Brazil. In addition, we describe the nymphal stage of A. goeldii for the first time. A total of 10 unpublished records of the adult stage of A. goeldii are recorded from the Amazonian region of Brazil, confirming the occurrence of A. goeldii in this country. Except for one record on the snake Boa constrictor Linnaeus, all records of A. goeldii reported in the present study were from anteaters (Pilosa: Myrmecophagidae). Our results, in conjunction with previous literature records, indicate that anteaters and large snakes are important hosts for the adult stage of A. goeldii. The nymph of A. goeldii is morphologically similar to the nymphs of Amblyomma romitii Tonelli-Rondelli, 1939, Amblyomma dissimile Koch, 1844, and A. rotundatum. We present a modification of a previously published taxonomic key of Amblyomma nymphs from Brazil, in order to perform taxonomic identification of the nymph of A. goeldii based on external morphology. The geographical distribution of A. goeldii appears to be restricted to the Amazonian region. There were no previous host records for the immature stages of A. goeldii, thus it is expected that the present nymphal description will facilitate further works on the ecology of this poorly studied tick species.

RESUMOO carrapato Amblyomma rotundatum é uma espécie partenogenética, encontrada principalmente em anfíbios e répteis silvestres em todos os biomas brasileiros. No presente relato, registra-se a ocorrência de dois machos dessa espécie de ixodídeo encontrados em um jabuti-tinga (Chelonoidis denticulatus) proveniente do município de Manaus, Amazonas, Brasil. Manaus, Amazonas, Brazil. Palavras-chave: carrapatos, Amblyomma rotundatum, machos ABSTRACT The Amblyomma rotundatum tick is a parthenogenetic species, found mainly in wild amphibians and reptiles in all Brazilian biomes. The present report records the occurrence of two males of this ixodid species found on yellow-footed tortoise (Chelonoidis denticulatus) from the municipality of

Fatal infections with Cytauxzoon felis are common in domestic cats, and jaguars ( Panthera onca ) are believed carriers of this protozoan. Fatal C. felis infections have never been described in jaguars before. Thus, this study describes such an infection in a 5-month-old captive-reared jaguar that presented hyporexia and died at 26 days after the first clinical signs. During necropsy, samples were taken from several tissues, some were fixed in 10% formalin and process for histopathological diagnosis, and some samples were used for DNA extraction, amplification via PCR and sequencing of the potential pathogens. Grossly, marked splenomegaly and icterus were observed. Histologically, numerous structures that are morphologically compatible with Cytauxzoon spp. schizonts obliterated multiple blood vessels in the brain, leptomeninges, spinal cord, lungs, heart, skeletal muscle, adrenal gland, kidneys, spleen, small intestine and pancreas. C. felis was identified by PCR in many organs. Thus, C. felis infection in jaguars can be fatal, and the clinicopathological findings are similar to those of cytauxzoonosis in other wild and domestic felid species.
