13. Comparative proteomic analysis of pathogenic and non-pathogenic strains from the swine pathogen Mycoplasma hyopneumoniae
Background: Mycoplasma hyopneumoniae is a highly infectious swine pathogen and is the causative agent of enzootic pneumonia (EP). Following the previous report of a proteomic survey of the pathogenic 7448 strain of swine pathogen, Mycoplasma hyopneumoniae, we performed comparative protein profiling of three M. hyopneumoniae strains, namely the non-pathogenic

14. Oral microbiota of Brazilian captive snakes
The present work aimed to determine the oral microbiotic composition of snakes from São José do Rio Preto city, São Paulo State, Brazil. Ten snake species, comprising the families Boidae, Colubridae, Elapidae and Viperidae, were submitted to microbiological examination of their oral cavity, which indicated positivity for all buccal samples. Gram-negative

15. Experimental infection of dogs with a Brazilian strain of Rickettsia rickettsii: clinical and laboratory findings
The bacterium Rickettsia rickettsii is the etiological agent of an acute, severe disease called Rocky Mountain spotted fever in the United States or Brazilian spotted fever (BSF) in Brazil. In addition to these two countries, the disease has also been reported to affect humans in Mexico, Costa Rica, Panama, Colombia and Argentina. Like humans, dogs are also

16. Brazilian spotted fever: a reemergent zoonosis
Brazilian spotted fever is caused by the bacterium Rickettsia rickettsii, which is the most pathogenic species of the spotted-fever rickettsiae group and is transmitted by the bite of infected ticks. Amblyomma cajennense is the most important tick species involved in the cycle of this zoonosis in Brazil as it presents low host specificity, great number of na

17. Listeria spp. e L. monocytogenes in the hot dog frankfurters production and consuption practices / Listeria spp. E Listeria monocytogenes NA PRODUÇÃO DE SALSICHAS TIPO HOT DOG E HÁBITOS DE CONSUMO
Listeria monocytogenes is a gram-positive bacterium, anaerobic facultative, that grows under refrigerator temperature and it can cause listeriosis in human and animals. It is widely distributed in the environment and it has been isolated from food of animal and vegetal origin that was associated to outbreaks of high lethality in many coutries. Thus, this bac

19. Estudos funcionais de uma possível cisteíno protease de Xanthomonas axonopodis pv. citri.
Cysteine proteases are enzymes found in many organisms and are characterized by the presence of cysteine residue in their active site. These proteases play an important role in the organism metabolism. In pathogenic organisms, for example, cysteine proteases may be involved in the pathogenicity process by unbalancing of the biological functions of the host (

20. A associação entre o zooplâncton e Vibrio cholerae O1 e O139 no complexo estuarino de Santos - Bertioga e Plataforma adjacente / The association between zooplankton and Vibrio cholerae O1 and O139 on Santos-Bertioga estuarine system and adjacent shelf
Vibrio cholerae is an autochthonous bacterium in the sea and may cause serious health problems when pathogenic strains are accidentally ingested. V. cholerae are found associated with copepods in concentrations up to a thousand times higher than the free bacteria in the water. If ingested, a single copepod may have enough bacteria necessary for human infecti

21. UTILIZAÇÃO DE LACTOBACILLUS PARACASEI COMO PROBIOTICO PARA O CONTROLE DE SALMONELLA SPP EM FRANGOS DE CORTE / UTILIZATION OF LACTOBACILLUS PARACASEI AS PROBIOTIC USE TO CONTROL THE SALMONELLA SPP IN COMMERCIAL POULTRY
The objective of the commercial poultry keeping is getting high productivity for a low cost and offering to the consumer a product with quality. A pathogenic bacterium that has been worring the avicola section during the last years is the Salmonella. To control this bacterium, it was proposed in this paper the Lactobacillus paracasei, used as probiotic. The

22. Citrus canker (Xanthomonas axonopodis pv. citri) and its interaction with citrus leafminer (Phyllocnistis citrella) on sweet orange (Citrus sinensis) / Cancro cítrico (Xanthomonas axonopodis pv. citri) e sua interação com a lagarta minadora dos citros (Phyllocnistis citrella) em laranja doce (Citrus sinensis)
Asiatic citrus canker, caused by X. axonopodispv.citri (Xac), is one of the most serious phytosanitary problems in Brazilian citrus crops.The introduction of the citrus leafminer (Phyllocnistis citrella [CLM]), has resulted in an increase in the number of disease foci and has changed the spatial pattern of citrus canker symptomatic trees from strong aggregat

23. Differential activity of a lectin from Solieria filiformis against human pathogenic bacteria
A lectin isolated from the red alga Solieria filiformis was evaluated for its effect on the growth of 8 gram-negative and 3 gram-positive bacteria cultivated in liquid medium (three independent experiments/bacterium). The lectin (500 µg/mL) stimulated the growth of the gram-positive species Bacillus cereus and inhibited the growth of the gram-negative speci

24. Antifungal activity of secondary metabolites produced by Bacillus pumilus MAIIIM4a, an endophytic from cassava. / Atividade antifúngica de metabólitos secundários produzidos pelo endófito de mandioca Bacillus pumilus MAIIIM4a.
Endophytic microorganisms are defined as organisms that inhabit the interior of a vegetable at least during a period of the vital cycle, without causing any apparent damage. In the search for new organisms and new secondary metabolites, a study was conducted to evaluate the chemical diversity of endophytic bacteria through the isolation and identification of
