We report the first isolation of Dengue virus 4 (DENV-4) in the state of São Paulo, from two patients - one living in São José do Rio Preto and the other one in Paulo de Faria, both cities located in the Northwest region of the state. The virus isolations were accomplished in the clone C6/36 Aedes albopictus cell line, followed by indirect immunofluorescence assays, performed with type-specific monoclonal antibodies that showed positive reactions for DENV-4. The results were confirmed by Nested RT-PCR and Real-Time RT-PCR assays. The introduction of DENV-4 in a country that already has to deal with the transmission of three other serotypes increases the possibility of the occurrence of more severe cases of the disease. The importance of early detection of dengue cases, before the virus spreads and major outbreaks occur, should be emphasized.

The present study provides a rickettsial serosurvey in 25 dogs and 35 humans in an endemic area for Brazilian spotted fever in the State of São Paulo, where the tick Amblyomma aureolatum is the main vector. Testing canine and human sera by indirect immunofluorescence against four Rickettsia antigens (R. rickettsii, R. parkeri, R. felis and R. bellii) showed that 16 (64%) of canine sera and 1 (2.8%) of human sera reacted to at least one of these rickettsial antigens with titers <FONT FACE=Symbol>³</FONT> 64. Seven canine sera and the single reactive human serum showed titers to R. rickettsii at least four times those of any of the other three antigens. The antibody titers in these 7 animals and 1 human were attributed to stimulation by R. rickettsii infection. No positive canine or human serum was attributed to stimulation by R. parkeri, R. felis, or R. bellii. Our serological results showed that dogs are important sentinels for the presence of R. rickettsii in areas where the tick A. aureolatum is the main vector of Brazilian spotted fever.

ABSTRACT No isolated factor influences soybean development and production more than the sowing date, but the responses of cultivars sown on different sowing dates depends on their sensitivity to environmental conditions. Thus, this study evaluated the adaptability and stability of 17 soybean genotypes in relation to yield, as well as to the grain oil and protein contents as a function of different sowing times. The experiment was designed in randomized blocks with three replications and a 17 × 5 factorial scheme. The genotypes were: Conquista, CD 223 AP, Elite, Garantia, Bioagro lineage, M-Soy 8400, M-soy 8001, Nambu, Sambaíba, Esplendor, UFVS 2006, UFVS 2005, UFVTN 102, UVF 18, UFV 16, Valiosa, Vencedora, and the five sowing dates were: SD1 = 11/3, SD2 = 11/20, SD3 = 12/07, SD4 = 12/23, and SD5 = 01/09. The M-Soy 8001, UFV 18 and Garantia genotypes showed high oil contents, with adaptation to all sowing dates and stability when sown on the most favorable dates. The Bioagro lineage, CD 223 AP, and Garantia genotypes were adapted and stable when sown on all sowing dates and had higher protein contents than the other genotypes, regardless of the sowing date. The Elite, Nambu, and Garantia genotypes were adapted and stable when sown on the most favorable sowing dates and presented high grain yields when sown in early December. The findings indicate that the Garantia genotype is the most suitable for the growing conditions of the central-north region of the state of São Paulo.

Abstract: Coloration anomalies are mainly genetically-based disorders in which body pigmentation is either reduced (hypopigmentation) or produced in excess (melanism), in parts or the totality of the body. Cases of hypopigmentation have been documented in many neotropical mammals, including the tayra (Eira barbara Linnaeus, 1758). We expand the account of anomalous coloration occurrence presenting new registers of hypopigmented tayras in Brazil. Data was collected during a mammal survey carried out in three agricultural landscapes within the Cerrado domain in the northeast of the state of São Paulo. We obtained two kinds of records of hypopigmented tayras, one from direct sighting and the other from a camera-trap. We discuss the likely implications of this conspicuous coloration to tayras and highlight some possibilities of study.

New bean cultivars, in addition to having high productivity, should meet requirements regarding the physiological attributes of the seeds, maintaining them during storage, minimising their deterioration and guaranteeing the producer a crop that is quickly and uniformly established. The aim of this study was to evaluate the physiological attributes of the seeds of thirteen bean cultivars (Phaseolus vulgaris L.) from the carioca commercial group, produced during the winterspring harvest in the North of the state of São Paulo, at two different times: after harvest and during the eighth month of storage. The experimental design was completely randomised, in a 13 x 2 factorial scheme with four replications. The factors corresponded to the 13 carioca bean cultivars (Pérola, BRSMG Majestoso, BRS Estilo, BRSMG Madrepérola, IPR Campos Gerais, IPR Tangará, IPR Andorinha, IPR 139, IAC Imperador, IAC Formoso, IAC Alvorada, IAC Milênio and Bola Cheia) and two periods of evaluation (0: after harvest and 8: eight months after harvest). Each of the cultivars under study displayed physiological qualities that were within the required standards after harvest. The BRS Estilo, BRSMG Madrepérola, BRSMG Majestoso, IAC Imperador and IPR Andorinha cultivars maintain germination within these standards after eight months of storage. The seeds of the IAC Imperador cultivar show greater vigour than those of the other cultivars when produced during the winter-spring harvest in the North of the state of São Paulo.

The study was conducted on 25 properties of the settlements São José I and Salvador, located in the municipalities of Brejo Alegre and Birigui, in the State of São Paulo, Brazil. A record of variables was elaborated and included data such as gender, breed and age of the animals. A total of 231 stool samples were collected from bovines aged one to six months, 128 being females and 103 males, 131 crossbred and 100 Holstein. Among the 231 samples, 17 (7.36%) were positive for Cryptosporidium spp. both by malachite green negative staining and by nested-PCR. Of the 17 positive samples, 14 were sequenced in agarose gel. These sequences were detected between 99% and 100% of genetic similarity for the following species. One sequence was similar to C. parvum (AB513880.1), one to C. bovis (MF074602.1), two to C. ryanae (KT922233.1), one to C. felis (KM977642.1) and nine were similar for C. andersoni reference MF350628. C. andersoni was found in animals aged 2–6 months, an age group which is different from those described by several authors. The presence of C. parvum indicates that the calves in the studied region should be considered a potential source for zoonotic transmission. For the first time to our knowledge, C. felis was identified in cattle in America.

In recent years, attacks by piranhas have become a common problem in dammed portions of rivers and streams in the State of Sao Paulo, Southeastern Brazil. In two outbreaks recorded in two neighboring counties in the Northwest region of the state, 74 bathers were bitten. Only one bite per person was recorded during a short period of the year. The bites were related to parental care and/or defense of spawning territory, which confirms previous studies and demystify the attacks by these legendary fish, as they are perceived by most people. Placement of fine mesh nets and removal of aquatic vegetation stopped the attacks.

The Pantanal Cat, Leopardus colocola braccatus, presents a broad distribution over several biomes in South America. However, the distribution of the species is based on a limited number of occurrences, and confirmed records of the species are scarce. Here, we present 2 confirmed records of Leopardus colocola braccatus from the state of São Paulo, southeast Brazil. Both records are juvenile individuals, 1 recorded in the municipality of Castilho and the other in Araçatuba. These São Paulo records expand the distribution of this uncommon felid to the most populous state of Brazil. This species is currently Data Deficient on the São Paulo Red List, and these new records may help with future assessments of the conservation status of this felid.

The present study aimed to analyze the occurrence of infection by Cryptosporidium spp. in mares and their respective foals. This study was carried out in 11 farms located in the municipalities of Araçatuba, Birigui, Guararapes and Santo Antônio do Aracangua, in the northwest region of the State of Sao Paulo, from November 2010 to March 2011. A total of 98 mares and 98 foals of several breeds were analyzed; among foals, 59 were males and 39 females, aged from three to 330 days. Feces were collected directly from the rectal ampulla, purified and processed according to modified Kinyoun stain. Occurrence of Cryptosporidium spp. was 21.4% (21/98) for foals and 18.4% (18/98) for mares. Occurrence of Cryptosporidium spp. had significant association with breeds and age of animals. Results obtained led to the conclusion that foals older than two months and Mangalarga animals are less susceptible to the occurrence of Cryptosporidium spp.
