Biotools: an R function to predict spatial gene diversity via an individual-based approach.

The gene diversity or expected heterozygosity (HE) is based on the allele frequency and is often used as a measure of genetic variability of populations. Knowing the pattern of spatial distribution of HE can be useful for determining strategies of conservation and sampling of collections of individuals. In addition, it can allow one to detect genetic boundaries in a landscape. We adapted a Wombling method based on assignment tests in a circular moving window extensively sampled over the study area in order to estimate HE at points of a prediction grid. The function sHe(), package biotools, is an easy-to-use and flexible implementation in R language that accepts as input geographical and genotyping data. The package biotools is distribution-free under the GPL-2/3 license and currently available from the Comprehensive R Archive Network (CRAN) at . The R platform and all R dependencies are similarly available from CRAN.

Genetic diversity of arboreal cotton populations of the Brazilian semiarid: a remnant primary gene pool for cotton cultivars.

Mocó cotton belong to the same species as the cultivated species, Gossypium hirsutum, and cultivated forms were mainly landraces but also developed as cultivars, bearing good fiber quality and drought tolerant when cropped as a perennial species. The northeast Brazil crop system based on this cotton type is finished, with a few small area planted in the three main States, where it was previously cultivated (Ceará, Paraíba, and Rio Grande do Norte), but in others, maintenance is accomplished by single dooryard plants. Plants were found in all visited Northeast Brazil municipalities, sometimes in the North of the country, and were collected for ex situ preservation and evaluation. Most of seeds had no fuzz (62.2%) and 94.6% of the genotypes presented spot in flowers. Seventy-one alleles were revealed in 12 loci. The genetic structure of the population evaluated by microsatellite markers shows two main groups, one comprising the Seridó region where landraces were originated and other comprising the state of Ceará, where a specific breeding program was developed. Genotypes collected in North Brazil States as well as those collected in Bahia, Alagoas, and Sergipe grouped with those collected in Ceará. The Mantel correlogram indicates a significant (P < 0.05) correlation between genetic and geographical distances up to 77 km. The ex situ maintenance and agronomical evaluation are the main concerns for mocó, as the use of the agricultural interesting traits, possibly introgressed to other genotypes, is predicted. The in situ preservation is still of interest since there is more diversity there than in the collected plants and some should be continued due to use as medicinal plant.

Adaptability and stability of genotypes of sweet sorghum by GGEBiplot and Toler methods.

Sweet sorghum has considerable potential for ethanol and energy production. The crop is adaptable and can be grown under a wide range of cultivation conditions in marginal areas; however, studies of phenotypic stability are lacking under tropical conditions. Various methods can be used to assess the stability of the crop. Some of these methods generate the same basic information, whereas others provide additional information on genotype x environment (G x E) interactions and/or a description of the genotypes and environments. In this study, we evaluated the complementarity of two methods, GGEBiplot and Toler, with the aim of achieving more detailed information on G x E interactions and their implications for selection of sweet sorghum genotypes. We used data from 25 sorghum genotypes grown in different environments and evaluated the following traits: flowering (FLOW), green mass yield (GMY), total soluble solids (TSS), and tons of Brix per hectare (TBH). Significant G x E interactions were found for all traits. The most stable genotypes identified with the GGEBiplot method were CMSXS643 for FLOW, CMSXS644 and CMSXS647 for GMY, CMSXS646 and CMSXS637 for TSS, and BRS511 and CMSXSS647 for TBH. Especially for TBH, the genotype BRS511 was classified as doubly desirable by the Toler method; however, unlike the result of the GGEBiplot method, the genotype CMSXS647 was also found to be doubly undesirable. The two analytical methods were complementary and enabled a more reliable identification of adapted and stable genotypes.

Expression of mRNAs coding for VAP1/crotastatin-like metalloproteases in the venom glands of three South American pit vipers assessed by quantitative real-time PCR.

Snake venom metalloproteases encompass a large family of toxins, with approximately 200 members already catalogued, which exhibit a diversity of structures and biological functions. From this relatively large number, only a dozen examples of apoptosis-inducing metalloproteases, like VAP1 and 2 from the venom of Crotalus atrox, are known. Since most VAP1-like toxins ever characterized were purified from the venom of Viperidae species inhabiting diverse places on earth, we investigate the expression of VAP-like metalloproteases in the venom gland of three representative pit vipers of the Brazilian territory. By molecular cloning and quantitative real-time polymerase chain reaction, using as calibrator gene the Crotalus durissus terrificus homolog of VAP1, named crotastatin, it is reported here that VAP1/crotastatin-like homologues in the venom gland of Bothrops atrox, C. d. cascavella and Lachesis m. rhombeata are expressed at different levels. Hence, batroxstatins, the crotastatin-like precursors from B. atrox, are expressed 87 times more than crotastatin-1, from C. d. cascavella, and 7.5-fold that lachestatins, from L. m. rhombeata. Moreover, in silico structural analysis of amino acid sequences indicates that batroxstatin-2, crotastatins and lachestatin-1 and -2 which share the archetypal motifs and metal- binding sites of VAP1, are subgrouped in a branch that comprises some apoptosis-inducing toxins.

Interventions to prevent urinary catheter-associated infections in children and neonates: a systematic review.

INTRODUCTION: Few data are available to inform strategies for the prevention of catheter-associated urinary tract infection (CAUTI) in children and neonates. Many recommendations are derived from studies in adults and cannot be applied to the paediatric population. OBJECTIVE: This study was aimed to identify all studies that measured the efficacy of an intervention for the prevention of CAUTI in children and neonates. METHODS: A systematic review using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) was conducted. Eligible studies published between January 1st, 1995 and December 31st, 2017, were identified in PubMed, the Cochrane Database of Systematic Reviews, LILACS, SciELO and DOAJ if applying an intervention with the aim of CAUTI prevention in inpatient children, infants or neonates. The following study designs were included: controlled and non-controlled before-and-after studies, (controlled) interrupted time series analyses and randomized controlled trials. Quantitative or qualitative studies on interventions in both adults and children were eligible if data on children could be extracted. Reviews, case series, letters, notes, conference abstracts and opinion articles were excluded. RESULTS: Of 99 articles identified, six were included in the final analysis, after consensus from three independent investigators. Four studies used a multimodal strategy (using at least four or more different components at the same time) as follows: aseptic rules during catheter insertion and removal; cleaning the urethral meatus with sterile water; use of a new silicone catheter per insertion with a closed sterile drainage system by a sterile technique; daily evaluation of catheter requirement; placement of indwelling urinary catheters only for approved indications; reducing of urinary catheter days and positioning of the patient and collection device to assist in urine drainage. One study tested periurethral cleaning intervention to reduce CAUTI. One study described the association of the presence of a physician safety champion with urinary catheter device utilization ratios. Catheter-associated UTI reduction rates were reported in four studies; three achieved statistically significant decreases in CAUTI rates. Positive results were achieved only when a multimodal strategy was used with at least four or more components. This strategy could be adopted for paediatric healthcare institutions to reduce CAUTI rates in children and neonates. CONCLUSION: Evidence exists to support the use of a multimodal strategy for CAUTI reduction in hospitalized children and neonates.

Role of antimicrobial stewardship programmes in children: a systematic review.

The United Nations and the World Health Organization have designated antimicrobial resistance (AMR) as a major health priority and developed action plans to reduce AMR in all healthcare settings. Establishment of institutional antimicrobial stewardship programmes (ASPs) is advocated as a key intervention to reduce antibiotic consumption in hospitals and address high rates of multi-drug-resistant (MDR) bacteria. PUBMED and the Cochrane Database of Systematic Reviews (January 2007-March 2017) were searched to identify studies reporting the effectiveness of ASPs in general paediatric wards and paediatric intensive care units (PICUs) for reducing antibiotic consumption, use of broad-spectrum/restricted antibiotics, and antibiotic resistance and healthcare-associated infections (HAIs). Neonatal units and antifungal agents were excluded. Of 2509 titles and abstracts, nine articles were eligible for inclusion in the final analysis. All studies reported a reduction in the use of broad-spectrum/restricted antibiotics or antibiotic consumption. One study reported a reduction in HAIs in a PICU, and another study evaluated bacterial resistance, showing no effect following ASP implementation. Prospective audit on antibiotic use was the most common ASP core component (eight of nine studies). Antibiotic pre-authorization was described in two studies. Other described interventions were the provision of guidelines or written information (five of nine studies), and training of healthcare professionals (one study). There is limited evidence for a reduction in antibiotic consumption and use of broad-spectrum/restricted agents following ASP implementation specifically in PICUs. Data evaluating the impact of ASPs on HAIs and AMR in PICUs are lacking. In addition, there is limited information on effective components of a successful ASP in PICUs.

Using atmospheric plasma to increase wettability, imbibition and germination of physically dormant seeds of Mimosa Caesalpiniafolia.

In this study, we analyzed seed wettability as well as imbibition and germination after treatment with atmospheric pressure cold plasma (APCP) using dielectric barrier discharge (DBD) in seeds that have very low germination rates. To aid industrial applications, several seeds were simultaneously treated with plasma within a space between two coaxial glass tubes sandwiched by two metal mesh screens that produced high-voltage pulses at 17.5kV with a frequency of 990Hz. Three treatment times (3min, 9min and 15min) as well as untreated seeds were used to conduct the wettability, imbibition and germination tests. The wettability and imbibition were found to be directly related to the treatment duration, but saturation of the imbibition was found for treatment durations greater than 9min. Plasma treatment was also effective in improving germination, but shorter treatment duration presented greater germination. This apparent contradiction is explained by the cell damage caused by the increased exposure to plasma, as observed in other studies. The results suggest that there must be an optimal wettability and imbibition condition that ensures that excessive moisture does not harm the germination process.

Most international guidelines on prevention of healthcare-associated infection lack comprehensive recommendations for neonates and children.

International infection prevention and control (IPC) guidelines provide standardized recommendations for healthcare-associated infection (HCAI) prevention in adults, but often lack specific information about neonates and children. We reviewed ten international IPC/HCAI guidelines to identify paediatric-specific recommendations for HCAI prevention. Hand hygiene, bloodstream infection, ventilator-associated pneumonia, environmental control and outbreak management were frequently reported with recommendations applicable to children and newborns, but documents on catheter-associated urinary tract infection and surgical site infection were lacking.

Comparative study on the efficacy and acceptability of two contraceptive pills administered by the vaginal route: an international multicenter clinical trial.

The efficacy and acceptability of two widely used oral contraceptive tablets, one containing 250 mg levonorgestrel and 50 micrograms ethinyl estradiol and the other containing 150 micrograms desogestrel and 30 micrograms ethinyl estradiol, administered by the vaginal route were compared in 1055 women studied over 12,630 woman-months of vaginal contraceptive pill use. This multicenter clinical trial was performed in nine countries of the developing world by the "South to South Cooperation in Reproductive Health," an organization founded by scientists from the Third World working in the area of reproductive health, and the study was developed and coordinated by one of these centers. The findings of this study confirm the efficacy of both these tablets when administered by the vaginal route. Involuntary pregnancy rates at 1 year of 2.78 for subjects in the levonorgestrel group and 4.54 for subjects the desogestrel group showed no statistically significant difference between the two groups. However, total discontinuation rates of 47.01 for subjects in the levonorgestrel group and 56.33 for subjects in the desogestrel group showed a statistically significant difference between the two groups, and discontinuation rates attributable to prolonged bleeding of 0.6 for subjects in the levonorgestrel group and 3.2 for subjects in the desogestrel group were also significantly higher in the group of subjects using the desogestrel vaginal contraceptive pill. Blood pressure remained at admission values throughout treatment. A statistically significant weight increase from admission values occurred in both groups of subjects.

PIP: Efficacy and acceptability of 2 combined oral contraceptive pills administered vaginally are summarized. This is the 1st collaborative trial published by the South to South Cooperation in Reproductive Health. 1055 women participated in 12,630 cycles, in 9 countries, from June 1988 to May 1991. The pills were commercially available tablets containing 50 mcg ethinyl estradiol and 250 mg levonorgestrel (Schering AG, Sao Paulo, Brazil), or 30 mcg ethinyl estradiol and 15 mcg desogestrel (Organon, Sao Paulo, Brazil). Subjects were aged 17-39 younger and of lower parity from Mexico and Dominican Republic and older from Egypt and China. All had at least 1 pregnancy. 675 participated for 6 months, 470 for 1 year, 364 for 18 months, and 210 for 2 years. The 1-year discontinuation rate averaged 47.01% for the levonorgestrel group and 56.33% for the desogestrel group (p = 0.0061); 2-year discontinuation rates were 48.01% and 69.36, respectively, explained in part by higher involuntary pregnancy rates and prolonged bleeding rates in the desogestrel group. The most common medical reasons for stopping contraception were unplanned pregnancy, vaginal or vulval irritation, nausea, vaginal discharge and headache. Vaginal irritation was reported by 1%, 9 in each group. There were 32 pregnancies, 14 in the levonorgestrel and 18 in the desogestrel group. 17 were in missed pill cycles and the rest were method failures, 6 in the levonorgestrel group and 9 in the desogestrel group. The Pearl index varied from 0 in Nigeria to 12.24 in Mexico, and was 2.45 for levonorgestrel vs. 3.74 for desogestrel. There was a wide variation in discontinuation rates by center: Brazil and China had few, while many women from Dominican Republic, Mexico and Zambia left the study. Bleeding problems were common complaints, more so in the desogestrel group. There were 363 women with intermenstrual bleeding (only once in 80%), 148 with spotting (only twice in 65%). Bleeding duration was significantly less in pill cycles than baseline, pressure. Women gained an average of 1 kg over 2 years, more in the desogestrel group. The pregnancy rate of 2.78 is within the range reported for levonorgestrel rings.

Conception control by vaginal administration of pills containing ethinyl estradiol and dl-norgestrel.

One hundred twenty-four women of reproductive age have used vaginal pills containing 50 micrograms dl-norgestrel and 35 micrograms ethinyl estradiol to prevent conception for periods ranging from 6 to 20 months. One thousand four hundred thirty-eight woman-months were recorded. No pregnancies occurred. Cycle control was good. Bleeding usually lasted 3 to 5 days, and the interval between withdrawal bleeding events was 26 to 30 days in 86% of the cycles. Amenorrhea, breakthrough bleeding, and spotting occurred rarely. The continuation rate at 1 year was 64%.

PIP: This paper reports the results of a clinical trial of124 women of reproductive age who relied on daily administration of a vaginal pill containing 50 mg dl-norgestrel in combination with 35 mcg ethinyl estradiol fro contraceptive purposes for 6-20 months. No pregnancies occurred in 1438 woman-months of abservation. Bleeding generally developed 3-5 days after insertion of the last pill and lasted an average of 3-5 days. The interval between withdrawal bleeding events was 26-30 days in 86% of cycles. Incidence of intermenstrual bleeding, spotting, and amenorrhea was minimal. No siginificant alterations in blood pressure or blood cell counts and hematocrit were noted. Vaginal discharge requiring treatment developed in 20.9% od subjects; however, this incidence is comparable to that found in oral contraceptive (OC) and IUD users and may thus be unrelated to the vaginal pill. After 1 year of use, 64% of the subjects opted to continue the vaginal pill. This contrasts favorably with continuation rates recorded at the same clinic for vaginal ring users (48%) and OC users (47%). Only 7 of the 44 vaginal pill discontinuers cited medical reasons; the majority gave trivial reasons, and several reapplied for inclusion in the vaginal pill trial a few months after discontinuation. These findings suggest that the vaginal pill avoids the undesirable side affects of the vaginal ring (e.g., expulsion, interference with coitus, odor) as well as those associated with the gastric absorption os steroids, demonstrates a low incidence of complications, and is highly effective in preventing pregnancy.

Long-term contraception with a single implant of the progestin ST-1435.

Silastic capsules containing the synthetic progestin ST-1435 was inserted in 282 women of reproductive age who desired long-term contraception. Each woman received a single implant for 6 months' use. After evaluating the experience of the first 45 subjects, replacement capsules were offered to women desirous of continuing the method after the initial 6 months of use. In the first 6-month segment one pregnancy and 1720 woman-months of use were recorded. The total experience, through as many as six segments of use was 3373 woman-months of use and one pregnancy. The Pearl Index is 0.36 per 100 woman-years. The single pregnancy, recorded in the 1st month of the first segment, may represent a conception prior to implant placement. Amenorrhea was the most common side effect reported, with 83% of the women having at least one nonbleeding interval longer than 60 days during the first segment of use.

Quantification of crotamine, a small basic myotoxin, in South American rattlesnake (Crotalus durissus terrificus) venom by enzyme-linked immunosorbent assay with parallel-lines analysis.

Intraspecific variation in Crotalus durissus terrificus venom composition was studied in relation to crotamine activity. Crotamine induces paralysis in extension of hind legs of mice and myonecrosis in skeletal muscle cells. To determine whether the venom of crotamine-negative rattlesnake contains a quantity of myotoxin incapable of inducing paralysis, we have developed a very sensitivity immunological assay method, an enzyme-linked immunoabsorbent assay (ELISA), capable of detecting 0.6 ng of purified crotamine. The parallel-lines analysis of ELISA data showed to be useful because it shows the reliability of the experimental conditions. A variation in the amount of myotoxin in the crotamine-positive venom was observed, but not less than 0.1 mg of crotamine per mg of venom. It was not possible to detect it in crotamine-negative venom even at high venom concentrations.

Identification of crotasin, a crotamine-related gene of Crotalus durissus terrificus.

Crotamine is a cationic peptide (4.9 kDa, pI 9.5) of South American rattlesnake, Crotalus durissus terrificus' venom. Its presence varies according to the subspecies or the geographical locality of a given species. At the genomic level, we observed the presence of 1.8 kb gene, Crt-p1, in crotamine-positive specimens and its absence in crotamine-negative ones. In this work, we described a crotamine-related 2.5 kb gene, crotasin (Cts-p2), isolated from crotamine-negative specimens. Reverse transcription coupled to polymerase chain reaction indicates that Cts-p2 is abundantly expressed in several snake tissues, but scarcely expressed in the venom gland. The genome of crotamine-positive specimen contains both Crt-p1 and Cts-p2 genes. The present data suggest that both crotamine and crotasin have evolved by duplication of a common ancestor gene, and the conservation of their three disulfide bonds indicates that they might adopt the same fold as beta-defensin. The physiological function of the crotasin is not yet known.

Cross reactivity of different specific Micrurus antivenom sera with homologous and heterologous snake venoms.

Coral snakes are the only Elapids in America. They are represented by three genera: Leptomicrurus, Micruroides and Micrurus, of which the latter are the most abundant and diversified group. Little is known about the biochemistry of Micrurus venoms due to low availability. Here, we present a study on the cross reactivity of different specific Micrurus antivenom with homologous and heterologous snake venoms in order to contribute to the generation of more efficient antiserum for therapeutic purposes. The three specific antisera tested, anti-Micrurus corallinus, anti-Micrurus frontalis, and anti-Micrurus spixii, as well as the bivalent anti-elapid venom sera, raised against a mixture (50% each) of Micrurus frontalis and Micrurus corallinus venoms, were assayed by Western Blot against Micrurus and non-Micrurus elapid venoms. An antisera raised against a recombinant alpha-neurotoxin-like protein from Micrurus corallinus venom, only reacted in Western blot with its homologous venom, indicating that this protein is specific for Micrurus corallinus coral snake.

Contraception with long acting subdermal implants: I. An effective and acceptable modality in international clinical trials.

This paper presents results of a double blind, multi-centered and multi-national study of two progestin only subdermal implants used for contraception. A regimen of six capsules of levonorgestrel (Ng) used by 492 women had a net cumulative 12-month pregnancy rate of 0.6 percent and a continuation rate of 74.6 percent. 498 women used six capsules of norgestrienone (R2010) and experienced a net cumulative 12-month pregnancy rate of 3.5 percent and a continuation rate of 79.4 percent. The difference in the pregnancy rate was significant at P less than 0.01, while there was no significant difference in the continuation rates. Menstrual problems were the principal reason for termination of the levonorgestrel regimen, accounting for approximately half of all terminations. There were significantly fewer menstrual problems among users of the norgestrienone (R2010) capsules; the net cumulative 12-month termination rate for this reason was 4.3 percent. Results are compared with continuation and termination rates for acceptors of the Copper T 200 at the same clinics. The low pregnancy rate and reasonably high continuation rate of the norgestrel implants coupled with the fact that the expected effective lifetime of a set of capsules is of the order of 3-5 years appears to warrant further development of this contraceptive regimen.

Contraceptive effectiveness of Silastic implants containing the progestin R-2323.

PIP: The long-term contraceptive effectiveness of subdermal silastic implants containing 30-40 mg of the progestin R-2323 (13-ethyl-17 alpha ethinyl-17 hydroxy-gona-4, 9,11-trien-3-one), was studied in 531 women. 98 women received 2 capsules (Group A), 180 received 3 capsules (Group B), 181 received 4 capsules (Group C) and 68 received 5 capsules (Group D). There were 5 pregnancies reported for Group A over 610 months of use, 3 pregnancies for 2124 months of use in Group B, 4 pregnancies for 2128 months of use in Group C, and Group D had 3 pregnancies over 732 months of use. All of the pregnancies in Group A occurred in the first 4 months while pregnancies in the other 3 groups generally occurred between Months 6-12 of use. Amenorrhea was most frequent during Months 2-6. The frequency of spotting and breakthrough bleeding was minimal.^ieng

Cloning and characterization of a repetitive 1.9 Kb HindIII DNA fragment from Crotalus durissus terrificus genome.

Eukaryote genomes are endowed with varying quantities of repeated DNA families. These families show different patterns of conservation among species, copy numbers, chromosomal distribution, and transcription. Characterization of repeated DNA sequences could help to understand the genome anatomy and organization or be used in molecular systematics and molecular evolution studies. We describe here a repetitive DNA sequence of the HindIII family present in the genome of the rattlesnake Crotalus durissus terrificus. In Brazil, the family Crotalus is comprised only by one species durissus, which include several subspecies. The number and distribution of these subspecies are controversial. In the present study, the genomic DNA of a female rattlesnake was digested with HindIII resulting in a strong 1.9 Kb band. A partial genomic library was constructed from the 1.9 Kb DNAs rescued from the agarose gel after HindIII digestion and ligated to the vector pGEM3Zf(+) (Promega). Analysis of 69 clones, 44 hybridized with the 1.9 Kb probe isolated from one of the clones-clone 76, indicating that the DNA isolated from this clone should represent the 1.9 Kb HindIII fragment. This 1.9 Kb HindIII DNA was completely characterized by sequencing.

[Results of the use of a therapeutic protocol for Plasmodium vivax for 5 days in 3 municipalities of the São Luís Island, State of Maranhao, Brazil]. / Resultado do uso de um esquema terapêutico para Plasmodium vivax em cinco dias em três Muncípios da Ilha de São Luís, Estado do Maranhao, Brasil.

A uniform therapeutic schedule of Chloroquine 1500mg (three days) and Primaquine 75mg (adult 15mg x 5 days) was used in 1232 patients suffering from malaria due to Plasmodium vivax occurring in Island of São Luis Maranhão State in the period between January of 1984 and December 1985. Of the cases, 499 (40.5%) concluded treatment, and of these 448 were cured. Fifty one patients who relapsed responded to a second course of the treatment.

[Anopheles (Culicidae, Anophelinae) and Malaria in Buriticupu-Santa Luzia, pre-Amazonic Maranhao]. / Anopheles (Culicidae, Anophelinae) e a Malária em Buriticupu-Santa Luzia, Pré-Amazônia maranhense.

Seven species belonging the subgenus Nyssorhyncus were found. Anopheles (N.) darlingi, the principal vector of human malaria, was the most abundant (53.1%) followed by A. (N.) evansae (21.0%, A. (N.) triannulatus (17.4%) e A. (N.) nuñeztovari (4.8%). The others, A. (N.) argyritarsis. A. (N.) oswaldoi and A. (N.) rangeli, were less frequently found, representing only 3.7% of the total sample. The anophelines were most frequent in both the extra (51.7%) and peridomiciles (45.7%). The intradomicile was visited by some specimens of the A. (N.) darlingi and A. (N.) evansae (active in both the rain and dry seasons, especially in the former, when the malaria reached high levels of transmission.

[Phlebotominae (Diptera: Psychodidae) of Lagoas, a city of Buriticupu, Amazonia of Maranhão. I. The richness and relative abundance of the species in an area of recent colonization]. / Phlebotominae (Diptera: Psychodidae) de Lagoas, município de Buriticupu, Amazônia Maranhense. I--Riqueza e abundância relativa das espécies em área de colonização recente.

In this study the diversity of the species and relative abundance of the sand flies in the Amazonian community of Lagoas, in Buriticupu, Maranhão State, was determined. The study consisted of adult sandflies captured with CD light-traps, Shannon-trap and manual aspiration tube, between 18 PM and 6 AM, once a month, from December/95 to January/97, in a forest fragment and in the domestic environment (peri and intra). In all, 9,393 specimens were captured (4,302 males and 5,140 females) distributed among 38 species (1 Brumptomyia and 37 Lutzomyia). The diversity and abundance of species was higher in the forest, followed by the peri and intra. The predominance in the wild ambient is a consequence of the potentialities found in the remaining fragments of the forest which have survived the lumber yard exploitation and agricultural activities. In the forest environment Lutzomyia whitmani (64.9%), L. migonei (27%) and L. serrana (3.6%) were the most frequent species. In the peri and intra domicile L. evandroi predominated (55.4% and 97.9%). The species, L. whitmani (33.4%) and L. migonei (6.4%), were important in the peri domicile. The peridomestic habit of 7.7% of the sand flies showed the greatest epidemiologic importance, due to the existence of patients with leishmaniasis ulcers, who believe they were infected near their habitations.
