Megalobulimus dryades, a new species from the Atlantic Forest in southeastern Brazil, and redescription of Megalobulimus gummatus (Gastropoda: Strophocheilidae)

Abstract Megalobulimus dryades sp. nov. is described from the Atlantic Forest in the Vale do Ribeira region, in the states of Paraná and São Paulo, S-SE Brazil, based on morphology. Representatives of the new species with white peristome and glossy periostracum have been misidentified as Megalobulimus gummatus (Hidalgo, 1870) since the 19th Century. The true M. gummatus is revised and redescribed, and its distribution is here restricted to Rio de Janeiro state. Externally, the new species differs from M. gummatus in having distinct protoconch color and sculpture, teleoconch sculpture marked by strong anastomosing rugosities and malleations, and lighter colored white-greyish head-foot. Internally, it presents distinct jaw and radular features, a talon, and a long convoluted penis bearing two flagella. Additional comparisons with other Brazilian congeneric species are also provided.

The Muscidae (Diptera) from the Atlantic Forest of Serra de Paranapiacaba, southestern Brazil

Abstract A first survey of Muscidae in the State of São Paulo (Southeastern Brazil) is presented here with a one-year of Malaise trap collecting from August 2010 to July 2011 at the Biological Reserve Alto da Serra de Paranapiacaba (23°4600-23°4710S, 46°1820-46°2040W, 750-891 m of altitude). A total of 1,284 individuals of muscids were collected, and 15 genera and 39 species of Muscidae were identified. So far, only one muscid species had been recorded to the Reserve, which now has its Muscidae diversity increased to 40 species. Thirteen species are new records for the State of São Paulo. With this, the number of species of Muscidae species known to occur in the State of São Paulo is increased to 169. The interval between November and February was higher in number of individuals and number of species. Muscidae presented a seasonal pattern, with more abundance and diversity in that interval. The study area is covered by secondary forest and very close to São Paulo metropolitan area, and the composition of the fauna of Muscidae signalizes this environment changing and anthropic stress with nine species with synanthropic habits, two of them are typically synanthropic species.

Considerando as dificuldades morfológicas para diagnosticar as espécies dessa família que infestam mamíferos, este estudo refere-se a uma nova ocorrência de Cheyletiella parasitivorax incluindo os poucos registros de literatura. Além disso, também está sendo apresentada uma chave dicotômica ilustrada para identificação de espécies desse gênero.(AU)

Rickettsial infection in equids, opossums and ticks in the municipality of Monte Mor, state of São Paulo, Brazil / Infecção por Rickettsia spp. em equídeos, gambás e carrapatos do município de Monte Mor, estado de São Paulo, Brasil

The aim of this study was to investigate rickettsial infection in equids, opossums and ticks in the municipality of Monte Mor, a place where a Brazilian spotted fever case occurred in 2005. In addition, characteristics possibly associated with seropositivity in horses were analyzed. Serum samples from horses, mules and opossums (Didelphis albiventris) were subjected to indirect immunofluorescence assay (IFA) against Rickettsia rickettsii. The ticks collected from the animals were identified and Amblyomma sculptum ticks from the equids were tested using PCR for Rickettsia spp. Anti-R. rickettsii antibodies were detected in 22.6% (14/62) of the horses, none of the mules and 21.7% (5/23) of the opossums. Among the variables analyzed, only age > 12 years showed a statistically significant association with seropositivity among horses. All of the 166 A. sculptum ticks tested using PCR were negative. The results showed that rickettsiae of the spotted fever group was circulating in the municipality of Monte Mor when the samples were collected and indicate a need for surveillance of Brazilian spotted fever in this region.(AU)

Este trabalho objetivou pesquisar a infecção por Rickettsia spp. em equídeos, gambás e carrapatos, do município de Monte Mor, local que teve um caso de febre maculosa brasileira, em 2005. Além disso, características possivelmente associadas com a soropositividade nos equinos foram analisadas. Soros de equinos, muares e gambás Didelphis albiventris foram submetidos à reação de imunofluorescência indireta (RIFI) contra Rickettsia rickettsii. Os carrapatos coletados dos animais foram identificados e os carrapatos Amblyomma sculptum dos equídeos foram testados pela PCR para Rickettsia spp. Anticorpos anti-R. rickettsii foram detectados em 22,6% (14/62) equinos, zero muares e 21,7% (5/23) gambás. Entre as variáveis analisadas, apenas a idade maior que 12 anos mostrou associação estatisticamente significante com a soropositividade em equinos. De 166 carrapatos A. sculptum testados pela PCR, todos foram negativos. Os resultados mostram que riquétsias do grupo da febre maculosa estavam circulando no município de Monte Mor, quando as amostras foram coletadas, e apontam para a necessidade de vigilância para a febre maculosa brasileira nessa região.(AU)

Seroprevalence and incidence of Leptospira spp. in domestic dogs in the Southeast region of São Paulo State, Brazil / Soroprevalência e incidência de Leptospira spp. em cães domésticos na região sudeste do estado de São Paulo, Brasil

Leptospirosis is a zoonotic disease caused by Leptospira and domestic dogs can act as host of some serovars. In order to analyze the transmission dynamics in a dog population, with and without immunization, a longitudinal study was carried out with a focus to evaluate antibody response and to identify serovars. Blood samples were collected in three consecutive years (2015 to 2017) from 331, 373 and 347 dogs respectively. The dog seroprevalence in each year was 11%, 7% and 14%, respectively, and the incidence in 2016 was 5% and in 2017, 14%. The most frequent serovars were Cynopteri and Butembo in 2015, Cynopteri, Butembo and Hardjoprajitno in 2016, and Canicola and Butembo in 2017. Dogs can play a role as sentinel animals and hosts of Leptospira serovars. The percentage of seropositive dogs due to vaccination was higher than the previous years without immunization and lower than in previous years for other serovars, which we interpret as evidence for the importance of immunization. These parameters associated with active canine population control are important for prevention and control of leptospirosis not only in dogs but alsoto inhibit the transmission between dogs and humans.(AU)

A leptospirose é uma zoonose causada pelo agente etiológico Leptospira. Cães domésticos atuam como hospedeiro de diversos sorovares deste agente. Com intuito de analisar a dinâmica da leptospirose em uma população canina, com e sem imunização, um estudo longitudinal foi realizado avaliando a resposta sorológica destes animais e identificando seus sorovares. Foram coletadas amostras de 331, 373 e 347 cães em três anos consecutivos (2015 a 2017). As soroprevalências foram de 11%, 7% e 14%, respectivamente, e a incidência em 2016 foi de 5% e em 2017 de 14%. Os sorovares mais frequentes foram Cynopteri e Butembo em 2015, Cynopteri, Butembo e Hardjoprajitno em 2016, e Canicola e Butembo em 2017. Estes cães estão atuando como bio-indicadores da presença de Leptospira na região do estudo, incluindo sorovares zoonóticos, e contribuindo com a sua manutenção no ambiente. A soropositividade para sorovares protegidos pela vacina foi mais alta do que nos anos anteriores à imunização, enquanto para os sorovares não protegidos pela vacina diminuiu, demonstrando a importância da imunização para essa população de cães. Medidas de prevenção e controle para a leptospirose, como imunização e controle populacional canino, são recomendadas no local para inibir a transmissão do agente entre as populações de cães e humanos envolvidas.(AU)

Molecular detection of Leishmania spp. in cattle from Brazil by means of PCR using internal transcribed spacer 1 / Detecção molecular de Leishmania spp. em gado no Brasil por PCR com espaçador interno transcrito 1

Leishmania spp. are important agents of human and animal leishmaniases that have an important impact on public health. In this study, we aimed to detect the circulation of Leishmania spp. in cattle from a visceral leishmaniasis non-endemic area of the state of São Paulo, Brazil. DNA was extracted from blood samples from 100 heifers in the municipality of Pirassununga and was amplified using primers specific for the first internal transcriber spacer (ITS1), to assess the presence of trypanosomatids. The assays revealed that one sample presented bands of between 300 and 350 base pairs. In GenBank, this sample matched 100% with Leishmania infantum (314 base pairs). The results suggest that cattle can be infected by Leishmania infantum in Brazil.(AU)

Estas amostras foram amplificadas com os iniciadores específicos para tripanosomatídeos Internal Transcriber Spacer 1 (ITS1). Os ensaios revelaram uma amostra com bandas entre 300 e 350 pares de base (pb). A amostra demonstrou 100% de identidade com Leishmania infantum (314 pb). Os resultados sugerem que o gado pode ser infectado por L. infantum no Brasil.(AU)

Seroepidemiological study of feline coronavirus (FCoV) infection in domiciled cats from Botucatu, São Paulo, Brazil / Estudo soroepidemiológico da infecção pelo coronavírus felino (FCOV) em gatos domiciliados de Botucatu, São Paulo, Brasil

Feline coronavirus (FCoV) is responsible for causing one of the most important infectious diseases of domestic and wild felids, the feline infectious peritonitis (FIP), which is an immune-mediated, systemic, progressive and fatal disease. FCoV is highly contagious, and infection is common in domestic feline populations worldwide. The present study aimed to determine the seropositivity of FCoV infection and its associated epidemiological variables (risk factors) in domiciled cats in Botucatu, São Paulo, Brazil. Whole blood samples (0.5-1mL) were collected from 151 cats, and sera were extracted by centrifugation. These sera were tested by an commercial enzyme-linked immunosorbent assay (ELISA) for the detection of IgG anti-FCoV antibodies. The assessed risk factors were age range, breed, gender, reproductive status, outdoor access and rearing mode (living alone or in a group). The seropositivity was 64.2% (97/151). There was no statistical significance for risk factors related to breed, gender or rearing mode. There were significant differences in seropositivity (p-values ≤0.05) for age range (p=0.0157), reproductive status (p=0.0074) and outdoor access (p=0.0001). This study verified a wide dissemination of FCoV in the studied population, with a higher than expected seropositivity for indoor cats. Among the risk factors, age range, reproductive status and outdoor access presented statistically significant differences, thus helping to establish an epidemiological profile of this population.(AU)

O coronavírus felino (FCoV) é responsável por causar uma das mais importantes doenças infecciosas que acometem os felinos domésticos e selvagens, a peritonite infecciosa felina (PIF), que é uma enfermidade imunomediada, sistêmica, progressiva e fatal. O FCoV é altamente contagioso e a infecção é comum nas populações de felinos domésticos por todo o mundo. O presente estudo objetivou determinar a soropositividade da infecção pelo FCoV e correlacionar variáveis epidemiológicas (fatores de risco) de gatos domiciliados de Botucatu, São Paulo, Brasil. Amostras de sangue total (0,5 a 1mL) foram colhidas de 151 gatos e os soros foram obtidos após centrifugação. Estes soros foram testados por um teste commercial de ELISA para detecção de anticorpos IgG anti-FCoV. Os fatores de risco avaliados foram faixa etária, raça, gênero, condição reprodutiva, acesso à rua e modo de criação (viver solitário ou em grupo). Observou-se uma soropositividade de 64,2% (97/151). Não houve significância estatística para os fatores de risco relacionados à raça, gênero e modo de criação. Houve significância estatística quanto a soropositividade (p-values ≤0,05) para os fatores de risco faixa etária (p=0,0157), condição reprodutiva (p=0,0074) e acesso à rua (p=0,0001). Através do presente estudo verificou-se que o FCoV está amplamente disseminado na população estudada, onde a soropositividade encontrada foi maior do que a esperada para gatos domiciliados. Dentre os fatores de risco, faixa etária, condição reprodutiva e acesso à rua apresentaram diferenças estatisticamente significativas, contribuindo assim, para se estabelecer um perfil epidemiológico desta população.(AU)

Dentre os fatores de risco, faixa etária, condição reprodutiva e acesso à rua apresentaram diferenças estatisticamente significativas, contribuindo assim, para se estabelecer um perfil epidemiológico desta população.(AU)

Characterization of insect galls from a vegetation area in Altinópolis, São Paulo State, Brazil

Herein, we studied the occurrence of insect galls from natural vegetation around the Itambé Cave, Altinópolis, SP, Brazil. A sampling effort of 7.5 hours resulted in 41 gall morphotypes on 21 host plant species from 14 families. The richest families of host plants in morphotypes were Fabaceae (N = 11), Euphorbiaceae (N = 7), and Malpighiaceae (N = 5). Copaifera langsdorffii Desf. (N = 8), Croton floribundus Spreng. (N = 7), Diplopterys pubipetala (A. Juss.) W.R. Anderson & C.C. Davis (N = 5), and Bauhinia holophylla (Bong.) Steud. (N = 4) were the super host plant species. Among the gall makers obtained, cecidomyiids were reared in 81% of cases and Hemiptera (Diaspididae), Hymenoptera (Eurytomidae), Coleoptera (Apion sp./Apionidae), and Lepidoptera in 4.5% of cases, each. The parasitoids belong to the Chalcidoidea superfamily (Hymenoptera). One new species of Camptoneuromyiia (Cecidomyiidae) was found in Smilax oblongifolia Pohl ex Griseb. (Smilacaceae) as inquiline and a new species of Lestodiplosis in Diplopterys pubipetala (Malpighiaceae) was a predator. We also present the first register of Bauhinia holophylla as host plants of Cecidomyiidae. We also present the first register of Bauhinia holophylla as host plants of Cecidomyiidae, and we expand the occurrence of Rochadiplosis tibouchinae Tavares, Lopesia spinosa Maia and Couridiplosis vena Maia to São Paulo State. The results of this paper are a continuation of the description of gall morphotypes from the vegetation in Northeastern São Paulo State, and they also increase knowledge about the diversity of host plant and gall-maker associations in the Neotropical region.

Detection of avian metapneumovirus subtype A from wild birds in the State of São Paulo, Brazil / Detecção de metapneumovirus aviário subtipo A em aves silvestres no estado de São Paulo, Brasil

The present study investigated the circulation of avian metapneumovirus (aMPV) in wild birds in Brazil. To do so, 131 samples from 366 oropharyngeal or cloacal swabs collected from 18 species of birds were tested individually or in pools by RT-PCR. Samples detected by RT-PCR were selected for DNA sequencing. Thirteen (9.9%) samples were detected by the RT-PCR targeting the N gene and four out of 13 samples were sequenced. Sequencing results showed a high identity with the aMPV subtype A. Our results confirm the circulation of the aMPV subtype A in wild birds in Brazil even five years after its last detection.(AU)

O presente estudo investigou a circulação de metapneumovírus aviário em aves silvestres no Brasil. Para tanto, 131 amostras de 366 suabes orofaringeanos ou cloacais coletados de 18 espécies de aves foram testadas individualmente ou na forma de pools por RT-PCR. As amostras detectadas por RT-PCR foram selecionadas para sequenciamento. Treze (9,9%) das amostras foram detectadas por RT-PCR tendo o gene N como alvo; destas, quatro foram sequenciadas com sucesso. Resultados do sequenciamento mostraram alta identidade com o aMPV de subtipo A. Nossos resultados confirmam a circulação de aMPV subtipo A em aves silvestres no Brasil mesmo cinco anos após sua última detecção.(AU)
