In the middle of a political and fiscal crisis, Brazilian government is applying successive budget cuts, including in science funding. Recent cuts radically affect research programs on biodiversity that are crucial components for design monitoring public policies nature conservation sustainable development. We analyze consequences such Research Program Biodiversity (PPBio), largest network Brazil (626 researchers, nine networks all biomes). holds substantial part world's tropical forests...
Although visceral leishmaniasis is primarily transmitted by a biological invertebrate vector, transmission in the absence of vector has been reported, including venereal humans. Considering possibility transmission, we studied genital lesions dogs naturally infected with and shedding Leishmania sp. semen. Approximately 200 were serologically tested for anti-Leishmania antibodies divided into three groups: 1) negative ( n = 20), 2) asymptomatic positive 3) symptomatic 20). Samples from both...
This study analyzes the occurrence and distribution of phylogenetic groups 391 strains Escherichia coli isolated from poultry, cattle, water buffalo. The frequency phylogroups was A = 19%, B1 57%, B2 2.3%, C 4.6%, D 2.8%, E 11%, F 3.3%. Phylogroups ( P < 0.001) 0.018) were associated with E. 0.002) 0.003) 0.017) report demonstrated that some are host analyzed results provide knowledge composition domestic animals.
The effects of bovine leukemia virus (BLV) on the immune response have been extensively investigated; however, its mammary gland immunity are only speculative. Although BLV has a tropism for B cells, it can affect both adaptive and innate immunities because these systems share many effector mechanisms. This scenario is basis this investigation immunity, which largely dependent upon neutrophilic functions. Thus, present study sought to examine functions lymphocyte profile in milk naturally...
Leishmaniasis is a zoonotic disease of major public health and veterinary importance, affecting 88 countries with up to 2 million cases per year. This review emphasizes the animal reservoirs spreading visceral leishmaniasis (VL) in urban areas, particularly two Brazilian metropolitan namely São Luis Belo Horizonte, where has become endemic past few years. Urbanization Brazil during last decades created favorable epidemiological conditions for maintenance disease, dense human populations...
O objetivo deste estudo foi explicar a associação dos fatores socioambientais e grandes usos da terra com ocorrência de casos leishmaniose tegumentar americana (LTA) nos circuitos espaciais produção, no Estado Minas Gerais, Brasil. Trata-se um ecológico do tipo analítico, baseado em dados secundários LTA dividido por triênio, período entre 2007 2011, cujas unidades análise foram os municípios pertencentes aos espaciais. Duas etapas distintas realizadas, sendo elaboração mapas temáticos...
De abril a maio de 2000 2002 oito localidades com remanescentes cerrados sensu stricto no estado São Paulo foram amostradas para o levantamento das espécies asteráceas, uma famílias mais representativas da flora herbáceo-arbustiva nestas formações. Foram feitas 23 amostragens e cada área estudo foi amostrada em média vez por ano durante pico floração plantas. Ao todo obtidas 399 amostras, nas quais reconhecidas 89 morfoespécies (74 identificadas como conhecidas). Quarenta cento registradas...
The aim of the study was to determine phylogenetic groups E. coli strains isolated from seemingly healthy broiler and condemned suspected colibacillosis in a Brazilian slaughterhouse. Samples respiratory tract edible giblets (liver heart) broilers with without macroscopic lesions were collected at slaughter. There 84 which 11 obtained swabs heart, 7 liver, 66 tract. Of 53 not condemned, 5 4 44 E tested via PCR for A, B1, B2, C, D, E, F. Phylogroups A B1 most common phylogroups sick-appearing...
Ecological theory of habitat heterogeneity and limited niche-similarity assumes that more heterogeneous environments provide a greater amount diversity resources than simple environments, resulting in species. This study aimed to evaluate the effect on richness dung beetles examine spatial patterns assemblage structure relation heterogeneity. Dung were collected using pitfall traps without bait 30 points distributed an area cerrado sensu lato, region Tangará da Serra, MT, Brazil, including...
Streptococcus dysgalactiae is a bacterium that accounts for notable proportion of both clinical and subclinical intramammary infections (IMIs). Thus, the present study explores function milk neutrophils lymphocyte profile in mammary glands naturally infected with . Here, we used 32 culture-negative control quarters from eight clinically healthy dairy cows low somatic cell counts 13 S. -infected six cows. Using flow cytometry, evaluated percentage monocytes/macrophages neutrophils, expression...
Abstract Background American tegumentary leishmaniasis (ATL) is a widespread anthropozoonosis caused by protozoa of the genus Leishmania and considered serious public health problem. The aim this study was to provide descriptive analysis confirmed ATL cases evaluate spatial distribution in high-risk transmission areas from state Minas Gerais, Brazil. Methods An ecological, analytical, retrospective Gerais 2007 2017 conducted. To characterize these cases, multiple correspondence...
A survey of the endophagous insects fauna associated to Asteraceae capitula was carried out from 2000 2002 in eight cerrado sensu stricto sites located Brazilian state São Paulo. Sixty-four species Diptera and Lepidoptera were recorded 49 asteracean host plants. Approximately half obtained a single locality, with large proportion emerging sample (unicates). Thirty percent singletons (i.e. only one individual recorded). The rare suggests high turnover among localities. Lepidopteran on more...
Anthropogenic changes in the landscape result an environmental mosaic with serious consequences for biodiversity. The aim of present study was to assess effects anthropogenic on Asteraceae richness and abundance, evaluate Tephritidae assemblages five sampling sites, three sampled habitats each: cerrado (Brazilian savanna), eucalyptus stands pasture. Sampling carried out 15 random transects (cerrados one pasture) 30 (eucalyptus remaining pastures). Composition, species insect abundance each...
The aim of this study was to investigate the relationship between clinical findings and bacterial isolation in milk samples meat-producing ewes. conducted 17 commercial flocks 550 udder halves from suckling Santa Ines Initially, examination mammary glands teats performed by visual inspection palpation halves; then a scoring system devised for all findings. After that, strip cup test California mastitis (CMT) were performed. Then, somatic cell counts (SCCs) bacteriological analyses collected....
ABSTRACT The wild cycle of rabies constitutes a serious challenge to epidemiological surveillance for disease control in domestic, companion or production animals, and humans. understanding virus circulation the natural environment is increasingly important due constancy reservoirs presence potential vectors infection humans domestic animals. Aiming evaluate occurrence State Sergipe total 935 hematophagous bats (Desmodus rotundus), 46 dogs (Cerdocyon thous) 24 primates (Callithrix spp.) were...
ABSTRACT: This study aimed to determine the virulence factors, phylogenetic groups, and relationships between pathovars groups of E. coli strains isolated from feces buffalo calves. A total 217 were obtained after culture screened by PCR for detection factors EAST-1, enterohemolysin, Saa, CNF2, F41, F5, STa, intimin, Stx1 Stx2. One hundred thirty-four isolates positive one or more factors: eighty-four diarrheic animals, fifty non-diarrheic The identified in ETEC (F5+) (2/84), NTEC (16/84),...
ABSTRACT A total of 480 milk samples were analyzed in four repetitions with preservative treatments (no preservative, Bronopol, Bronolat and Brononata), three storage times at temperatures up to 4 °C (24, 48 72hours after reception), five different water additions (0.0, 2.5, 5.0, 7.5 10.0%) two analytical instruments (electronic cryoscope FTIR). The objective this study was evaluate the effect these parameters determination freezing point by reference method Fourier transform infrared...
