Multiple factors can be involved in the virulence processes of Aeromonas hydrophila. The objective present paper was to verify presence aerolysin, hidrolipase, elastase and lipase genes through polymerase chain reaction (PCR) A. hydrophila isolates obtained from fish São Francisco River Valley, evaluate according these Nile tilapia fingerlings. One hundred fourteen bacteria were used. DNA heat extracted PCR undertaken using specific primers described literature. For vivo tests fingerlings...
S. aureus is considered the main etiologic agent of mastitis, standing out for its ability to produce biofilm, a structure resistance against antibiotics and host's immune system. Iron an essential micronutrient in different biochemical pathways, being associated with regulation gene expression biofilm production. In turn, iron chelators prevent use this nutrient by microorganisms, impairing growth. Therefore, objective study was evaluate interference (sodium alginate 2,2'-bipyridyl) on...
Caseous lymphadenits (CL) is a chronic and subclinical disease that affects goats sheep and, consequently, causes economic losses, especially to small producers. The purpose of this study, through use Polymerase Chain Reaction (PCR), was verify the presence virulence genes phospholipase D (PLD), integral membrane protein (FagA), iron enterobactin transporter (FagB), ATP binding cytoplasmic (FagC) siderophore (FagD) in 168 isolates C. pseudotuberculosis obtained from cases caseous...
To verify the occurrence of caseous lymphadenitis in sheep and goats on farms Pernambuco, Brazil, animals slaughtered two Brazilian cities (Petrolina/PE Juazeiro/BA), to characterize susceptibility profile Corynebacterium pseudotuberculosis disinfectants antimicrobials, its relationship with biofilm production were objectives this study. 398 samples tested for sensitivity antimicrobial drugs, disinfectants, production. Among 108 collected properties, 75% positive C. pseudotuberculosis....
ABSTRACT The development of new strategies for production low‐cost deoxyribonucleic acid (DNA) adsorbents based on electrospun fibers block copolymers [Eudragit E‐100/poly(ethylene oxide) (PEO)] is a promising way fast retrieval free degradation double‐stranded DNA chains from aqueous solution. adsorption takes place through electrostatic interaction between and oppositely charged that provide high surface area adsorption. capacity observed Eudragit E100/PEO (considering as target molecules...
A pitiose é uma doença infecciosa causada pelo oomiceto aquático P. insidiosum que acomete animais e o homem, especialmente habitantes de áreas úmidas. enfermidade apresenta como característica principal a formação lesões com aspecto granulomatoso nos hospedeiros. Neste trabalho, relatou-se ocorrência da em ovinos estados Pernambuco (PE) Bahia (BA), Nordeste do Brasil, bem foi avaliada eficácia um imunoterápico frente esta enfermidade. Amostras sangue 53 foram coletadas, sendo 49 oriundos...
ABSTRACT: Cladonia substellata Vainio is a lichen found in different regions of the world, including Northeast Brazil. It contains several secondary metabolites with biological activity, usnic acid, which has exhibited wide range activities. The aim this study was to evaluate vitro antimicrobial activity organic extract C. and purified acid. Initially, Staphylococcus spp., derived from samples skin ears dogs cats suspected pyoderma otitis, were isolated analyzed. In susceptibility testing...
ABSTRACT: Aeromonas hydrophila is a common fish pathogen that causes extensive damage to aquaculture. To develop and implement more adequate strategy farm fish, it crucial understand the bacterial-resistance levels their transference dynamics. The objective of this study was analyze resistance profile isolated antimicrobial agents heavy metals draw correlation observed profiles with presence plasmids. Resistance bacteria (oxacilin, gentamicin, tetracycline, nalidixic acid) (cadmium, lead,...
Canine Degenerative Myelopathy is a late onset recessive autosomal disease characterized by progressive ascending degeneration of the spinal cord. Two causal mutations are associated with this disease: transition ( c . 118G>A ) in exon 2 SOD1 that was described several breeds and transversion 52A>T 1 same gene Bernese Mountain dogs. The aim study to understand impact : 118G > A mutation genotyping population German Shepherd dogs Brazil. PCR-RFLP approach used genotype 97 healthy...
RESUMO A suinocultura é uma atividade pecuária bem consolidada no Brasil. Por outro lado a colibacilose neonatal, cujo patógeno Escherichia coli, pode diminuir produtividade nas granjas e causar prejuízos aos produtores. O tratamento baseia-se na utilização de drogas antimicrobianas. Todavia, o uso indiscriminado dessas substâncias tem levado seleção cepas resistentes. Diante disso, busca por alternativas terapêuticas, como as plantas medicinais, se tornado cada vez mais comum. Dessa...
This study aimed to describe the kinetics of Leishmania parasite load determined using kinetoplast DNA (kDNA)-based quantitative polymerase chain reaction (qPCR) in visceral leishmaniasis (VL) patients.Parasite blood was assessed by qPCR at five time points, up 12 months post-diagnosis. Sixteen patients were followed up.A significant reduction observed after treatment (P < 0.0001). One patient had an increased 3 post-treatment and relapsed clinically month six.We have described use...
Aeromonas veronii is a Gram-negative bacterial species that causes disease in fish and nowadays increasingly recurrent enteric infections of humans. This study was performed to characterize newly sequenced isolates by comparing them with complete genomes deposited at the NCBI (National Center for Biotechnology Information). Nine from fish, environments, humans São Francisco Valley (Petrolina, Pernambuco, Brazil) were compared available public databases gain insight into taxonomic assignment...
The objectives of this study were to assess the effect intake aflatoxin on development tilapia and evaluate impact inoculation with Aeromonas hydrophila performance parameters, so these two individual tests performed. One hundred twenty fingerlings aged 35 days old, mean weight 1.55 ± 0.005 g length 5 cm used in each test, distributed 20 tanks. Each experimental unit consisted a 60 L tank six fingerlings. In first experiment, increasing levels (0.350, 0.757, 1.177 mg.kg feed-1) as treatments...
ABSTRACT: The semiarid northeast of Brazil contains a unique biome known as caatinga, with maximum temperature 40 ºC and relativity humidity 56%. caatinga is characterized by variety plants, including Cereus jamacaru Dc (mandacaru), Poincianella microphylla Mart. ex G. Don (catingueira), Pilosocereus gounellei FAC Weber (xique-xique) Mimosa tenuiflora (Willd.) Poir (jurema preta). Sheep goat industries are economically strong in that region, despite the fact caseous lymphadenitis highly...
Mastitis is responsible for both damage to animal health and economic losses the industry. To identify effective treatments this disease, products extracted from a variety of plants with antimicrobial potential have gained attention. The present study aimed assess in vitro antibacterial ethanolic extract two plant species Caatinga biome against bacteria isolated small ruminants subclinical mastitis. leaves Mimosa tenuiflora Commiphora leptophloeos were dried processed obtain crude extracts...
Farming of Nile tilapia is in full development throughout the world. However, an increase still seen prevalence and severity bacterial diseases. The aim this study was to develop a vaccine against Aeromonas hydrophila (Oreochromis niloticus) based on protein patterns S-layer proteins. proteins were extracted using glycine NaOH with subsequent visualization through SDS-PAGE. Based observed, bacterins produced that tested experiment vivo use 144 fingerlings distributed 24 aquariums completely...
