Antigenic similarities to Paracoccidioides brasiliensis in thermo-dependent dimorphic fungi isolated from soil in Botucatu, SP, Brazil

We compared the antigenic characteristics of two thermo-dependent dimorphic fungi isolated from soil in Botucatu, an endemic area of paracoccidioidomycosis (PCM) and Paracoccidioides brasiliensis. The soil isolates grew as cerebriform colonies at 37 degrees C (yeast form) and as cottonous colonies at 25 degrees C (mycelial form). No pathogenicity for ddY mice or hamsters were observed. In immunodiffusion test, there were precipitation bands between the 2 soil isolates and pooled PCM patient sera. There were also common precipitation bands at 21, 50 and 58 kDa between the soil isolates antigens and PCM patient sera by Western-blotting, but no gp43 kDa band. No gene for gp43 kDa protein was detected in the soil isolates by PCR. The fact that these isolates were obtained from an endemic area of PCM and there were some antigenic similarities between the soil isolates and P. brasiliensis in immunodiffusion test and Western-blotting may have some importance in epidemiological surveys done with paracoccidioidin as well interfering with the immune response of the exposed population.

Factors associated with exclusive breastfeeding in children under four months old in Botucatu-Sp, Brazil

This study aimed to identify factors associated with exclusive breastfeeding (AME) and the reasons mothers presented to introduce complementary feeding in the first four months of life. A total of 380 mothers (92.2%) of children under four months old vaccinated in a Multi-vaccination Campaign were interviewed. To identify factors associated to AME, univariate and multiple logistic regressions analyses were performed. Thirty-eight percent of the children were on AME; 33.4% consumed cow milk; 29.2% tea; and 22.4% water. The mothers justified introduction of cow milk by factors related to quantity/quality of maternal milk and necessity of the child. The use of a pacifier (odds ratio=2.63; CI95%=1.7-4.06) and difficulty to breastfeed (odds ratio=1.57., CI95%=1.02-2.41) were associated with the absence of AME. The populational attributable risk percentage for the use of a pacifier was estimated at 46.8%. Thus, modifiable risk factors were associated with AME interruption.

Phytosociological study of the tree stratum of a semideciduous mesophytic forest in the municipality of Botucatu, SP, Brazil

The phytosociological structure was studied in an area of semideciduous mesophytic forest lied on the ascent of the Cuesta of Botucatu. Once the relief of the area was very heterogeneous, the forest, for the sampling process, was divided in three sampling regions: the upper one (on the plateau), the middle one (on the ascent properly said) and the lower one (on the plain). Through the point-centered method, 1224 (408 in each region) trees were sampled. For this work, only the trees with shaft equal or higher than 1.30m high were considered. The three sampling regions showed some interesting differences in regard to the phytosociologic structure. Once there are differences among the soil of the three regions, the variations in the structure must be connected to the differences in the soil.

Modelagem da variação horária da temperatura do ar em Petrolina, PE, e Botucatu, SP

The air temperature is a climatic element of interest for several agricultural related studies. Hence, daily air temperature from two locations in Brazil (Botucatu and Petrolina, with different climate classification), hourly recorded from January 2004 to December 2005, were analysed to verify if 24 h long air temperature variation can be predicted with 6 h interval records. Three data set were selected, with different first time record of air temperature, and analyses performed using geoestatistics to confirm the temporal dependency of records. Then, ordinary krigging was used to model air temperature variation within 1 h interval, and spherical model presented the best approach, with range of 11.6 h for Botucatu and 12.7 for Petrolina. For both locations, the time of air temperature recording was the most importnat factor on accuracy of estimation of air temperature variation. Records at 2, 8, 14 and 20 h and at 4, 10, 16 and 22 h presented the best approaches, but for records at 9, 15 and 21 h, the approach was worst.

Doenças respiratórias em aves atendidas no laboratório de oriento- Patologia da FMVZ-UNESP/Botucatu-SP, Brasil, nos anos de 2005 A 2006

The respiratory tract of birds shows anatomical and physiological characteristics that facilitates the occurrence of disease, mainly those of microbiological origin. This article analyzes the frequency of respiratory diseases in domestic and wild birds treated during the years 2005-2006 at the Ornitopathology Laboratory of the Veterinary Hospital, Faculty of Veterinary Medicine and Zootecnics, São Paulo State University (FMVZUNESP). Diagnoses were obtained through clinical and radiographic exams as well as haemogram, microbiological culture, parasitological tests and necropsy, being septicemic processes, aspergillosis and mycoplasmosis the most diagnosed diseases. No zoonotic threats were identified, so the entities were described as of low-impact on public health. However, the above mentioned agents can provoke death of birds and difficult for treating and eradication as well.

Caracteristicas de padroes de drenagem de areas com entalhes erosivos no municipio de Botucatu - SP

Descriptive and quantitative characteristics of the drainage pattern of two places very susceptible to erosive process, located in the municipality of Botucatu-SP, were studied through photo-interpretative methods. The analysis and discussion of the obtained results led to the conclusion that the geologic control in the area B, masking the effect of the relief and terrain permeability, increases the drainage density, the length of channels and the angularity of the channels of 3rd and 4th order. -from English summary

Numero de dias de ocorrencia de orvalho em Botucatu, SP.

This paper analyses the dew occurrence in Botucatu, Sao Paulo State, Brazil, in the period from 1971 to 1984. The phenomenon was observed on the grass plot of the Climatological Station in the 'Presidente Medici' Experimental Farm. The station is installed on soil 'Terra Roxa Estruturada', on a middle slope, declivity of 8% and east exposure. Days with dew were summed for the following periods: month, year, season, no rainy period and rainy period. For each period the following values were calculated: mean, mean standard errors and mean confidence interval. Also the absolute extreme values and the amplitude of variation were determined. The confidence interval of the mean were calculated by the 't' statistic, at the level of 5% of error probability. The means were compared by using the 't' statistic, at the level of 5% of error probability. The following table of values corresponds to the regime of dew occurrence in Botucatu, expressed in number of days with dew. The dew occurrence regime in Botucatu was analysed comparatively with the regime at Itatinga, in Sao Paulo State and with the regime of Rio Grande, in Rio Grande do Sul State. -English summary

Penfigo foliaceo no Hospital das Clinicas da Faculdade de Medicina de Botucatu, SP

BACKGROUND - Pemphigus foliaceus is an autoimmune bullous disease that is endemic in Brazil and in other South American countries such as Paraguay, Bolivia, Peru and Colombia. OBJECTIVES - To compare the observed clinical and epidemiological data with those referred in the literature. METHOD - Retrospective study in patients with pemphigus foliaceus admitted to and treated at University Hospital of the School of Medicine of Botucatu, SP, Brazil, from 1976 to 1993, analyzing the following variables: age, sex, race, origin and onset of disease. RESULTS - From 1976 to 1993, 63 patients were treated, with an average of 3.7 cases/year. Patients within the age range of 20 to 60 years old were the most affected. Most of the patients were white, females being slightly more affected than males. The majority of male patients were rural workers. Some towns presented higher incidence of cases. Most of the patients from rural areas became sick mainly in summer and in autumn. Occurrence of similar cases was observed in blood-related family members and neighbors. CONCLUSIONS - Clinical and epidemiological data were similar to those referred in the literature.

Análise estrutural e aspectos do mosaico sucessional de uma floresta semidecídua em Botucatu, SP

The objective of the present paper was to study the structure of a semi-deciduous forest. The main purpose was to verify if the floristic composition and/or structure is influenced by the mosaic developmental phase. The study has been done in 200 plots, each one measuring 10 × 10 m, forming a grid of 200m × 100 m in the center of the forest fragment. In to separate the study area in units representing different phases of forest mosaic (gap, construction and mature), the plots were classified by cluster analysis based on structural traits. The species with the highest influence the community structure were Aspidosperma polyneuron, Trichilia claussenii and Trichilia catigua.Gap, construction and mature phases presented different patterns in spite of the three species influence.

Ecological interaction between Atta sexdens (Hymenoptera: Formicidae) and the vegetation of a mesophyll semideciduous forest fragment in Botucatu, SP, Brazil

Among 89 plants species growing in a subtropical dry forest fragment located in Botucatu, State of São Paulo, Brazil, 35 species were cut by Atta sexdens, representing 39.34% of the current plants existing in this area. A. sexdens L., 1758 (Hymenoptera: Formicidae) has a selective preference for the following species: Alchornea triplinervia, Faramea cyanea, Cariniana estrellensis and Casearea obliqua, with the first being the most cut species. The frequency and absolute densities of the plant families and species significantly influence the selection process. When comparing the absolute frequency regarding the 10 most cut plant species and the cutting frequency, significant data were obtained only for the euphorbiaceous A. triplinervia species, proving the preference of A. sexdens for this species in particular. These interactions are discussed based on ecological and management factors in agro-ecosystems.

Subnotificação de acidentes do trabalho não fatais em Botucatu, SP, 2002

Objective: The implementation of work-related injury prevention policies has been hindered by underreporting of incidents among formal workers, and substantial underreporting among informal workforce. This study aimed at estimating the underreporting of work-related injury in a median-sized city. Methods: A random survey was carried out among residences in the urban area of Brazil. Residents were interviewed about the occurrence of work-related injury to people aged more than nine years in the last 90 days. All incidents reported were double checked in the National Social Security Institute (INSS) records. Results: There were 9,626 residences visited. It was estimated 79.5% (CI 95%: 78.8%-80.3%) of underreporting of work-related injury. Conclusions: Work-related injury reporting is poor in the study location and this may be occurring in other cities. Data suggest the need to build up information systems on Brazilian workers' health. It should incorporate methods, materials and human recourses necessary to recognize, store, analyze, and spread information support injury prevention policies and promote workers' health programs.

Qualidade da água utilizada para irrigação de hortaliças na região de Botucatu-SP

This work had as objective verifies the water quality used for irrigation by the vegetables producers of Botucatu-SP area. They were interviewed 27 producers that sell vegetables in the street markets of Botucatu. Among these producers, ten were selected, being one of each place. Three samples of water of each source were collected. The main standard to evaluate the obtained results were the CONAMA Resolution (National Environment Council) N° 357, March 17, 2005, that it establishes the standard for water classification. The Electric Conductivity was evaluated of agreement value suggested by CETESB and the color was verified according to OMS (Health World Organization), for potable water due to CONAMA Resolution not to stipulate a value for classification. For the public health, just the coliformes and nitrate are the preoccupying variables for they be related with the incidence of diseases, so, the analyzed waters, 40% of them (A, F, H and J producers) offer some risk for the health of Botucatu population, second established standard for CONAMA. We can to conclude that in a general way, those waters, are in conditions no alarming, because they don't present values very different from those established by the legislation.
