Anopheline species were sampled in different ecotones at Maracá Ecological Station and in Cantá municipality, both in Roraima State, Brazil, in June 2016.  Nine species were recorded. Six species belong to the subgenus Nyssorhynchus and three species to the subgenus Anopheles. The most abundant species collected were Anopheles triannulatus s.l., Anopheles nuneztovari s.l. and Anopheles oswaldoi species B. The remaining species had frequencies lower than 10%. While A. triannulatus s.l. was the most frequent and the most widely distributed species in the studied area, Anopheles darlingi Root, the main malaria vector in the Brazilian Amazon region, was captured in two different ecotones and in low frequency. Our findings suggest that the risk of malaria outbreaks at Maracá Ecological Station may be low. This study also describes the first record of Anopheles costai Fonseca & Ramos in Maracá Ecological Station, Roraima State, increasing the distribution range of this taxon.

Endemic Areas

In view of recent studies incriminating several species of anophelines, besides Anopheles darlingi, as malaria vectors in the Brazilian Amazon, we performed an anopheline survey in four localities - Ariquemes, Cujubim, Machadinho and Itapoã do Oeste - in Rondônia, the most malarious State in the Country. Twenty species were found. An. darlingi was, by far, the dominant species and the only one whose density coincided with that of malaria. On human baits it was more numerous in the immediate vincinity of houses than indoors whre, however, it was almost the only species encountered. On both situations it fed mostly at sunset and during the first half of the night. It was less numerous far from houses and scarce inside the forest. Other species (An. triannulatus, An. evansae, An. albitarsis, An. strodei) appeared in appreciable numbers only in Ariquemes, both in areas with and without malaria. The remaining species were scanty. An. darlingi was confirmed as the primary local vector.

A New Species

Paraxiphidium is a genus of flashy Neotropical katydids belonging to Conocephalini. Paraxiphidium iriodes sp. nov. is described from the Brazilian Amazon region. This is the first record of the genus for Brazil. The description of stridulatory file, male internal genitalia and data on natural history is provided. A key is included to the species of the group and a map with the geographical records completes the paper.

Notoedric Mange

This paper describes a case of notoedric mange in an ocelot (Leopardus pardalis) in the Brazilian Amazon region. A young male of approximately four months of age that was illegally kept as a pet was apprehended in Altamira, State of Pará, northern Brazil. The animal was transported to the Mangal das Garças Park in the state's capital city of Belém. The ocelot had pruritus and lesions suggestive of scabies in the head. Skin scraping material was examined under optic microscopy. There was seen a large number of eggs, larvae, nymphs and adult mites. The mean female and male sizes were 230.2 × 200.4 µm and 137.6 × 104.9 µm. Based on the morphologic characteristics and morphometric analysis, this mite was classified as Notoedres cati. This is the first report of notoedric mange in L. pardalis from Brazilian Amazon.

Furuncular Myiasis

Abstract Two individuals of the jaguar, Panthera onca (L.), were captured near the municipality of Presidente Figueiredo, Brazilian Amazon, during the years of 2017 and 2018. The jaguars presented furuncular myiasis caused by the human botfly Dermatobia hominis (L.) on the rear thighs and tail. This is the first record of infestation of D. hominis in P. onca in the Amazon region.

The Impact

Surgical site infection (SSI) following caesarean section is associated with increased morbidity, mortality, and significant health care costs. This study evaluated the epidemiological, clinical, and microbiological features of Acinetobacter spp. in women with SSIs who have undergone caesarean section at a referral hospital in the Brazilian Amazon region. This study included 69 women with post-caesarean SSI by Acinetobacter spp. admitted to the hospital between January 2012 and May 2015. The 69 Acinetobacter isolates were subjected to molecular species identification, antimicrobial susceptibility testing, detection of carbapenemase-encoding genes, and genotyping. The main complications of post-caesarean SSI by Acinetobacter were inadequate and prolonged antibiotic therapy, sepsis, prolonged hospitalization, and re-suture procedures. A. baumannii, A. nosocomialis and A. colistiniresistens species were identified among the isolates. Carbapenem resistance was associated with OXA-23-producing A. baumannii isolates and IMP-1-producing A. nosocomialis isolate. Patients with multidrug-resistant A. baumannii infection showed worse clinical courses. Dissemination of persistent epidemic clones was observed, and the main clonal complexes (CC) for A. baumannii were CC231 and CC236 (Oxford scheme) and CC1 and CC15 (Pasteur scheme). This is the first report of a long-term Acinetobacter spp. outbreak in women who underwent caesarean section at a Brazilian hospital. This study demonstrates the impact of multidrug resistance on the clinical course of post-caesarean infections.

The Impact

A total of 187 different species of arboviruses and other viruses in vertebrates were identified at the Evandro Chagas Institute (IEC) from 1954 to 1998, among more than 10,000 arbovirus strains isolated from humans, hematophagous insects, and wild and sentinel vertebrates. Despite intensive studies in the Brazilian Amazon region, especially in Pará State, very little is known about most of these viruses, except for information on date, time, source, and method of isolation, as well as their capacity to infect laboratory animals. This paper reviews ecological and epidemiological data and analyzes the impact of vector and host population changes on various viruses as a result of profound changes in the natural environment. Deforestation, mining, dam and highway construction, human colonization, and urbanization were the main manmade environmental changes associated with the emergence and/or reemergence of relevant arboviruses, including some known pathogens for humans.
