Infecção pelo vírus da Febre do Nilo Ocidental em equinos no Estado de São Paulo / West Nile Fever virus infection in horses in São Paulo state, Brazil

Background: The West Nile virus (WNV) antibodies were reported in Brazil in the serum samples taken from horses andbirds in the Midwest region and Paraíba state in 2008 and 2013, respectively. In 2014, the first human case was confirmedin a rural worker in the state of Piauí and, in 2018, the virus was isolated from the central nervous system of a horse withnervous symptoms in the state of Espírito Santo. The virus is a member of the Flaviviridae family of the genus Flavivirus(neurotropic), infecting several mammalian species, with humans and horses being the most susceptible. Approximately35% of horses develop clinical signs, thus they are considered the best sentinels for this disease. The aim of this case reportis to describe the first confirmed cases of West Nile Fever (WNF) in two horses in the state of São Paulo.Cases: Two horses with neurological symptoms were treated at the Veterinary Hospital of Cruzeiro do Sul University (SãoPaulo, SP), in 2019. Both horses came from neighboring regions that have a large Atlantic Forest preservation area and arealso routes for migratory birds, known to be competent hosts for transmitting the West Nile Fever virus, such as the swallow,the falcon and the hawk. The first one had symptoms, such as weakness and sporadic seizures; however, after recovering,it was hospitalized a few days later due to kidney failure and laminitis. The second one showed incoordination, pelviclimb weakness, and was walking in circles, evolving to seizures. Both animals were euthanized, and their central nervoussystem samples and total blood samples were tested for rabies, herpes virus, and WNV; the first 2 tests showed negativeresults.

Checklist of the birds of Mato Grosso do Sul state, Brazil: diversity and conservation

Several phytogeographic regions (Cerrado, Pantanal, Atlantic Forest, Gran Chaco, and Chiquitano Dry Forests) converge in the state of Mato Grosso do Sul, Brazil, and influence regional biodiversity. Despite a list of birds in the state of Mato Grosso do Sul being published by Nunes et al. (2017), it is necessary to update and critically review avifauna records. In this study, we gathered the results of several records obtained from species lists and online data platforms of the 336 sites in this state over the last decades and grouped them into Main (Primary and Secondary) and Tertiary Lists. The avifauna of Mato Grosso do Sul is composed of 678 species, of which 643 (95%) have records proving their occurrence (Primary List), whereas 34 still lack documentation (Secondary List). The number of related species for Mato Grosso do Sul represents 34% of the Brazilian avifauna. Some species stand out for their unique occurrence in Mato Grosso do Sul, such as Melanerpes cactorum, Celeus lugubris, Phaethornis subochraceus, and Cantorchilus guarayanus, reflecting the influence of different phytogeographic regions of the Chaco and Chiquitano Dry Forests. Migrants represent 20% of the bird community occurring in the state, of which 93 species correspond to migrants from various regions of South America (south and west) and 40 to boreal migrants. Thirty-three species perform nomadic movements across the Pantanal Plain and other regions of the state. Thirty-one species are included in some conservation-threatened categories of global and/or national endangered species lists. Other 30 species are included in the near-threatened category at the global level and 23 at the national level. In addition, species typical of dry forests (in Serra da Bodoquena and Maciço do Urucum) and those from the Atlantic Forest in the south of the state deserve attention due to their restricted distribution and the high anthropogenic pressure on their habitat.(AU)

Description of a new species of Engraulicola George 1960 (Monogenea: Gastrocotylidae) parasitizing gills of Chloroscombrus chrysurus (Carangidae) from Veracruz, southern Gulf of Mexico / Descrição de uma nova espécie de Engraulicola George 1960 (Monogenea: Gastrocotylidae) parasito de brânquias de Chloroscombrus chrysurus (Carangidae) de Veracruz, Sul do Golfo do México

Engraulicola lamothei n. sp. (Monogenea: Gastrocotylidae) is described from the gills of Chloroscombrus chrysurus (Teleostei: Carangidae) from Veracruz, southern Gulf of Mexico. This monogenean is 1110-1670 (1328) µm long and 260-550 (363) µm wide. The haptor is asymmetrical, the long side has several clamps (35-42), and the short side has a single clamp; the posterior end has a small lappet armed with two dissimilar pairs of hooks. Male and female genital pores open near the anterior body end; the male genital pore is ventral, armed with a corona of 12 spines; the female pore is dorsal and unarmed. The new species differs from Engraulicola forcipopenis George, 1960 and from Engraulicola micropharyngella Unnithan, 1967 by lacking a pair of pointed forceps-like spines at the end of the penis amid the corona spines, and from Engraulicola thrissocles Tripathi, 1959 by the number of clamps on both sides, the number the hook pairs on the terminal lappet and the testis number. This is the first record of the genus Engaulicola George, 1960 on the Atlantic West Coast.(AU)

Engraulicola lamothei n. sp. (Monogenea: Gastrocotylidae) é descrito a partir das brânquias de Chloroscombrus chrysurus (Teleostei: Carangidae) de Veracruz, Sul do Golfo do México. Este monogêneo tem 1110-1670 (1328) µm de comprimento e 260-550 (363) µm de largura. O haptor é assimétrico, o lado longo tem vários grampos (35-42), e o lado curto tem um único grampo, e a extremidade posterior tem um pequeno lappet armado com dois pares de ganchos diferentes. Os poros genitais masculino e feminino são abertos perto da extremidade anterior do corpo; o poro genital masculino é ventral, armado com uma coroa de 12 espinhos; o poro feminino é dorsal e desarmado. A nova espécie difere de Engraulicola forcipopenis George, 1960 e de Engraulicola micropharyngella Unnithan, 1967, pela ausência de um par de fórceps pontiagudos como espinhos localizados na extremidade do pênis, em meio aos espinhos da coroa; e de Engraulicola thrissocles Tripathi, 1959, pelo número de pinças em ambos os lados, pelo número de pares de ganchos no lappet terminal, e pelo número de testículos. Este é o primeiro registro do gênero Engaulicola George, 1960 para a costa oeste do Atlântico.(AU)

Do Morphological Similarities and human-induced dispersal explain the non-native occurrence of Serpulidae (Annelida) in Southwest Atlantic? Taxonomic detailing is the key

Species of Serpulidae are common on benthic and biofouling communities, occurring attached on both natural and artificial substrates. In this paper, Serpulids were collected from intertidal to subtidal areas, on rocky shore and suspended artificial plates in port areas. Herein we report three new records of serpulid species to the coast of Rio de Janeiro, Brazil. We also discuss the misidentification of Spirobranchus tetraceros, which was previously reported to the north of Rio de Janeiro.

Rickettsial pathogens circulating in urban districts of Rio de Janeiro, without report of human Brazilian Spotted Fever / Circulação de patógenos riquetsiais em bairros urbanos do Rio de Janeiro sem relatos humanos da Febre Maculosa Brasileira

Spotted fever group rickettsioses are emerging diseases. In some of these diseases, domestic dogs act as sentinels. Canine serological studies have demonstrated that rickettsial dispersion is concentrated in rural areas, seroprevalence being higher where human rickettsioses are endemic. In Rio de Janeiro, the Atlantic forest vegetation has been devastated by urbanization. In this context, we aimed to detect Rickettsia spp. in urban areas of the West Zone of Rio de Janeiro. Sera from 130 dogs were tested by Indirect Immunofluorescence Assay, and ticks collected from these dogs were tested by polymerase chain reaction. We found the rate of serological reactions against R. rickettsii and R. parkeri in our study area to exceed those of rural and non-endemic areas, highlighting the importance of dogs as urban sentinels. The possibility of contact with opossums and capybaras increased the chances of exposure to Rickettsia spp., reinforcing the hypothetical link between the landscape and the rickettsial wild cycle. Rhipicephalus sanguineus sensu lato was the tick most frequently observed. PCR-positive samples showed similarity with R. rickettsii and R. felis, an emerging pathogen rarely reported from ticks. We observed that rickettsiae circulate in urban places and ticks from indoor environments, which may be involved in bacterial epidemiology.(AU)

Riquetsioses do Grupo da Febre Maculosa são doenças emergentes. Em algumas destas doenças, os cães domésticos agem como sentinelas. Estudos sorológicos caninos têm demonstrado que a dispersão de patógenos rickettsiais está concentrada em áreas rurais, sendo a soroprevalência maior onde as rickettsioses humanas são endêmicas. Na cidade do Rio de Janeiro, a vegetação de Mata Atlântica vem sendo devastada pela urbanização. Nesse contexto, objetivou-se detectar a presença de Rickettsia spp. em áreas urbanas da Zona Oeste do Rio de Janeiro. Amostras de soro obtidas de 130 cães foram testadas, utilizando-se a Imunofluorescência Indireta. Carrapatos coletados desses cães foram testados, utilizando-se a reação em cadeia da polimerase. Observou-se que as taxas de reações sorológicas contra R. rickettsii e R. parkeri nessa área de estudo excederam a prevalência das áreas rurais e não endêmicas, destacando-se a importância dos cães como sentinelas urbanos das rickettsioses. A possibilidade de contato com capivaras e gambás favoreceu a exposição à Rickettsia spp., reforçando a hipótese de ligação entre a paisagem local e o ciclo silvestre de transmissão riquetsial. O carrapato Rhipicephalus sanguineus sensu lato foi encontrado com maior frequência. Amostras com positividade pela PCR mostraram similaridade com R. rickettsii e R. felis, um patógeno emergente raramente descrito em carrapatos. Observou-se circulação riquetsial em áreas urbanas e em carrapatos obtidos do ambiente doméstico, os quais podem estar envolvidos na epidemiologia dessas bactérias.(AU)

Association between deep-water scale-worms (Annelida: Polynoidae) and black corals (Cnidaria: Antipatharia) in the Southwestern Atlantic

Polynoid scale-worms have been found living as commensals with deep-water antipatharians (commonly known as black corals) in the Potiguar Basin, off Rio Grande do Norte State, Northeastern Brazil. In this paper two polychaete species and four black corals species are redescribed. Benhamipolynoe cf. antipathicola and Parahololepidella cf. greeffi, and the black coral Stylopathes adinocrada Opresko, 2006 are recorded for the Southwestern Atlantic. Benhamipolynoe cf. antipathicola was first described from off New Zealand and the Malay Archipelago, as symbiont with the black coral Stylopathes tenuispina (Silberfeld, 1909). It was later reported for the North Atlantic, off Florida, associated with Stylopathes columnaris (Duchassaing, 1870). In our study, B. cf. antipathicola was found in association with the black coral S. adinocrada. Parahololepidella cf. greeffi was first described as a free-living from shallow waters off São Tomé and Cabo Verde Islands, West Africa, and later reported as symbiont with the black coral Tanacetipathes cf. spinescens in the same location. Our data expand both the geographical distribution and the host range of this species which is reported for the first time as symbiont with Tanacetipathes barbadensis (Brook, 1889), T. tanacetum (Pourtalès, 1880) and T. thamnea (Warner, 1981) in Brazil. The aim of this study is to discuss commensal associations between two species of scale-worm polynoids and black corals found in the Southwestern Atlantic, and also reporting their global distribution. Finally, we provided an updated list of the commensal polynoids and their black coral hosts.

On the identity of Porcellana paivacarvalhoi Rodrigues da Costa, 1968 (Crustacea: Anomura: Porcellanidae)

Porcellana paivacarvalhoi Rodrigues da Costa, 1968, described from southeastern Brazil (São Sebastião, São Paulo), is morphologically similar to the eastern Atlantic P. platycheles (Pennant, 1777), and also to the west African P. africana Chace, 1956. The synonymy between P. paivacarvalhoi and P. platycheles was proposed by previous authors without examination of any specimens of P. platycheles, nor did they considered the morphological similarities between P. paivacarvalhoi and P. africana. This synonymy has been implicitly accepted without further analysis. The recent discovery of one male and two females syntypes of P. paivacarvalhoi has prompted new investigations into the status of P. paivacarvalhoi as a junior synonym either of P. platycheles or P. africana. Porcellana paivacarvalhoi is redescribed and illustrated based upon its lectotype herein designated. It is confirmed to be a junior synonym of P. platycheles; all evidence suggests that P. africana is a distinct, separate species. All previous records of P. platycheles from the Brazilian coast are reviewed. Its presence in southeastern Brazil in the late 1960’s most probably represents an historical case of human-mediated introduction by shipping activities. Porcellana platycheles did not manage to establish itself in São Sebastião, nor has it been recorded subsequently elsewhere in Brazil.

External morphology, postcranial and appendicular osteology of three southwestern Atlantic flatfishes ( Paralichthys, Paralichthyidae), and comparisons with other congeneric species

Comparisons of the external morphology and analysis of osteological features of the postcranial and appendicular skeletons of three southwestern Atlantic flatfish species of the genus Paralichthys (P. isosceles, P. orbignyanus and P. patagonicus) were carried out. Bones are described, and detailed morphological, morphometric and meristic characteristics of these flounders are given in order to provide information about the external and internal morphology of three species of Paralichthys occurring in the south-west Atlantic waters that add new information and will help regarding within the framework of a phylogenetic study of the group. Interspecific differences were found in the number of vertebrae and intermuscular bones, as well as in the morphology and morphometry of vertebrae, caudal skeletons, pectoral and pelvic girdle bones. Relationships between bones are discussed and bone characteristics compared with those found in other species of Paralichthys and in other pleuronectiform species. The position of Paralichthys isosceles within Paralichthys is discussed, along with other congeners such as P. triocellatus and P. oblongus.(AU)

Environmental structure and relationships in the setting of natural water springs in a Lower Highland Seasonal Forest in Brazilian South / Estrutura e relações ambientais no entorno de nascentes em uma Floresta Latifoliada Subtropical no Sul do Brasil

The aim of this research was to characterize an environmental structure in the setting of tree natural water springs in a Lower Highland Seasonal Forest, and to verify the relationship between community demography and soil variables as subsidies for species identification in riparian forest recovery programs in similar environments. The research was carried out in the National Forest of Chapecó, located in the west of the state of Santa Catarina in the southern region of Brazil. For this, three water springs were demarcated, where 26 plots of 200m² in each were allocated. All individuals with diameter at 1.30m of soil height ≥5.0cm were measured. Soil samples (0 to 20cm depth) were collected in the plots for chemical and physical analysis. To relate the abundance of the species to the edaphic variables, the Canonical Correspondence Analysis (CCA) was used. A total of 76 species belonging to 64 genera of 36 botanical families were reported in the study area. The families Fabaceae and Myrtaceae presented greater floristic richness. The edaphic variables that most influenced the distribution of the species were aluminum saturation and calcium, magnesium and potassium contents. Specific groups of indicator species were formed for each water spring. The species designated as generalists are the most recommended for the initial filling and recovery of degraded springs. Further rare species and with low density must be included after the initial recovery to increase diversity.(AU)

O presente trabalho teve como objetivo caracterizar a vegetação arbórea em nascentes de Floresta Latifoliada Subtropical e verificar a relação entre a demografia da comunidade e variáveis edáficas, como subsídios para indicação de espécies em programas de recuperação de florestas ciliares de ambientes similares. O trabalho foi realizado na Floresta Nacional de Chapecó, localizada no oeste do estado de Santa Catarina no sul do Brasil. Para isso, foram demarcadas três nascentes, onde foram alocadas 26 parcelas de 200m2 em cada uma. Todas as árvores com Diâmetro a Altura do Peito (DAP) ≥5,0cm a 1,30m de altura do solo foram mensurados. Coletaram-se amostras de solo (0 a 20cm de profundidade) nas parcelas para análise das propriedades químicas e físicas. Para relacionar a abundância das espécies com as variáveis edáficas utilizou-se a Análise de Correspondência Canônica (CCA). Foram encontradas na área de estudo, 76 espécies pertencentes a 64 gêneros de 36 famílias botânicas. As famílias Fabaceae e Myrtaceae apresentaram maior riqueza florística. As variáveis edáficas que mais influenciaram na distribuição das espécies foram a saturação por alumínio e os teores de cálcio, magnésio e potássio. Ocorreu a formação de grupos específicos de espécies indicadoras para cada nascente. As espécies designadas como generalistas são as mais recomendadas para a recomposição de nascentes com a função de preenchimento inicial da área. Enquanto as espécies raras e de baixa densidade devem ser incluídas após a recuperação inicial com a função de aumentar a diversidade.(AU)

Age structure and growth of the rough scad, Trachurus lathami (Teleostei: Carangidae), in the Southeastern Brazilian Bight

The rough scad, Trachurus lathami Nichols, 1920, is a small pelagic species distributed along the West Atlantic coast. It is most abundant in the Southern Brazil (28°30’-34°S) and in the Southeastern Brazilian Bight (SEBB, 22°-28°30’S). The rough scad is fished by purse seines, which main target is the Brazilian sardine, Sardinella brasiliensis (Steindachner, 1879). Age and growth are vital to understand the life cycle of a species, to fishery management and ecosystem modeling. This study aimed to assess the age and growth of T. lathami, to identify its age structure in the SEBB, and to evaluate what causes the wide differences among Trachurus species in terms of body size and growth parameters. Data available on T. lathami was attained between 2008 and 2010 from surveys at SEBB. A total of 278 whole otoliths of T. lathami, total length between 27 mm and 208 mm, were analyzed and compared with the only other source of otolith data, from 1975. Three blind readings were performed and assessed using traditional methods to study fish age and growth. Zero up to eight rings were found, each ring corresponding to one year in the life of an individual of this species. The von Bertalanffy growth model parameters were L∞ = 211.90 mm and K = 0.319 year-1. The results of the analyses have shown similarities between 1975 and 2008-2010, indicating that the otolith development, the growth pattern and the age structure remained stable. T. lathami is the smallest species of Trachurus and it has the highest growth rates among them. This is probably related to the different temperatures where larvae/juvenile and adult grow, to the absence of a strong fishing pressure and to decadal population variability.

New record of the rare Atlantic Forest rodent Phyllomys lundi (Mammalia: Rodentia)

The arboreal echimyid rodent of the genus Phyllomys Lund, 1839 is found in the eastern Brazilian Atlantic forest, from the state of Ceará to the state of Rio Grande do Sul, reaching the São Francisco and Paraná river basins in the west. There are 13 species in the genus. Phyllomys lundi Leite, 2003, which until now was known from only two localities, is one of the four endemic Atlantic Forest species of Phyllomys with very restricted distribution. We provide additional data on the morphology, distribution and phylogeography (based on cytochrome b sequences) of the rare P. lundi . Our new record broadens the northern limit of the distribution P. lundi by approximately 250 km with respect to previous records.
