| Biliary atresia, the most common cause of liver transplantation in children, remains a challenge for clinicians and investigators. The development of new therapeutic options, besides the typical hepatoportoenterostomy, depends on a greater understanding of its pathogenesis and how it relates to the clinical phenotypes at diagnosis and the rate of disease progression. In this review, we present a perspective of how recent research has advanced the understanding of the disease and has improved clinical care protocols. Molecular and morphological analyses at diagnosis point to the potential contributions of polymorphism in the CFC1 and VEGF genes to the pathogenesis of the disease, and to an association between the degree of bile duct proliferation and... |

| An epidemiological study was carried out on 2823 cows from 34 dairy herds from Goiania in the State of Goias-Brazil during 2001 to 2002. The pregnancy rate was 47.8%. In 1473 non-pregnant cows, causes of reproductive failure problems were sought. The most prevalent uterine infection was endometritis (17.0%). Uterine disorders such as partial hypoplasia of the genital system (0.04%), macerate fetus (0.01%), adhesion of ovaries (0.04%), stillbirth (0.04%), retained placenta (0.01%), cervix inflammation (0.6%) and abortion (0.88%) also were found. Uterine swabs were collected aseptically for microbiological culture. Gram positives cocci (41.3%) and Gram negatives rods (52.6%) were found, and Staphylococcus aureus and Escherichia coli were the most prevalent... |

| The literature indicates that acute pancreatitis is a complication of massive hemolysis with a prevalence of about 20%. We describe an experimental model of hemolysis-induced acute pancreatitis. Hemolytic anemia was induced in rats by a single ip injection of 60 mg/kg of 20 mg/ml acetylphenylhydrazine (APH) in 20% (v/v) ethanol on the first experimental day (day 0). One hundred and fifty Wistar albino rats weighing 180-200 g were divided into three groups of 50 animals each: groups 1, 2 and 3 were injected ip with APH, 20% ethanol, and physiological saline, respectively. Ten rats from each group were sacrificed on study days 1, 2, 3, 4 and 5. Serum amylase, lipase levels and pancreatic tissue tumor necrosis factor-alpha (TNF-alpha) and platelet-activating... |

| Abstract Tinea capitis is generally considered as the most frequent fungal infection in childhood, as it accounts for approximately 92% of all mycosis in children. The epidemiology of this disease varies widely ranging from antropophillic, zoophilic, and geophillic dermatophytes, as the main causative agent in different geographic areas, depending on several additional factors. Nowadays, the etiology is considered to vary with age, as well with gender, and general health condition. The former reported extraordinary Tinea capitis case reports have been replaced by original articles and researches dealing with progressively changing patterns in etiology and clinical manifestation of the disease. This fact is indicative that under the umbrella of the... |

| Inflammatory bowel disease (IBD), which includes Crohn's disease (CD) and ulcerative colitis (UC), is a chronic disorder that affects thousands of people around the world. These diseases are characterized by exacerbated uncontrolled intestinal inflammation that leads to poor quality of life in affected patients. Although the exact cause of IBD still remains unknown, compelling evidence suggests that the interplay among immune deregulation, environmental factors, and genetic polymorphisms contributes to the multifactorial nature of the disease. Therefore, in this review we present classical and novel findings regarding IBD etiopathogenesis. Considering the genetic causes of the diseases, alterations in about 100 genes or allelic variants, most of them in... |

| The main microbial diseases affecting marine cultured bivalves have been revised on the basis of the etiologic agents, pathogenesis and pathogenicity. Several recent bivalve-interaction models have been studied, including Pecten larvae-Vibrio pectinicida, brown ring disease, juvenile oyster disease, Pacific oyster nocardiosis and summer mortalities of oysters. In addition, the taxonomy and phylogeny of new potential bivalve pathogens and their virulence factors have been established. Facing the difficulty of identifying bacterial strains associated with molluscan diseases (mainly vibriosis), polyphasic approaches have been developed to correlate the phenotype and genotype of potential pathogens. By evaluating likely virulence mechanisms, developing... |

| Two hundred and three samples of feces of calves aged less than 30 days old from both sexes and from different properties and regions of the state of São Paulo were examined in the period of two years. Bacterial cultures were carried out in bovine 10% bloodagar and Levine mediums, incubated for up to 96 hours in aerobic conditions at 37°C, with the observation of colonies and morphological and biochemical study to characterize isolated microorganisms, or other tests, when pertinent. ELISA was performed for the Rotavirus research. The Cryptosporydium spp was surveyed and its parasitological examination was made. Results revealed the involvement of several enteropathogens alone and associated. Rotavirus was found in 51 (25.1%) samples, being 58.8% alone and... |

| The objetive of this work was to identify the pectolytic bacteria associated with soft rot of arracacha roots in Brazil. From 1998 to 2001, 227 isolates of Erwinia spp. were obtained from arracacha roots and identified by biochemical and physiological tests (pectolytic activity, lecithinase, a-methyl glucoside, phosphatase, erythromycin sensivity, growth at 37ºC). Of these isolates, 89.9% were identified as E. chrysanthemi (Ech), 9.7% as E. carotovora subsp. carotovora (Ecc) and 0.5% as E. carotovora subsp. atroseptica. The identity of seventeen out of twenty representative isolates of Ech and Ecc was confirmed by PCR (primers '149f', 'L1r', 'ADE1', 'ADE2'). |

| A nivel mundial, México ocupa el primer lugar en producción y exportación de chayote (Sechium edule) tipo verde liso. La principal zona de producción se ubica en la región central de Veracruz, principalmente en los municipios de Coscomatepec, Huatusco, Ixhuatlán del Café, Chocamán, Tlilapan, Orizaba, Rafael Delgado y Amatlán de los Reyes. Como consecuencia del éxito comercial del chayote en los mercados de Norteamérica, la superficie de la producción nacional como monocultivo ha aumentado considerablemente, lo que ha generado la aparición de problemas fitosanitarios, principalmente la marchitez de plantas. Los productores han asociado este síntoma con Phytophthora spp. y aplican para su control fungicidas a base de metalaxyl, lo cual reduce la incidencia... |

| ABSTRACT In 2013, soursop trees showing symptoms of root rot were observed in a field in Maceió, state of Alagoas, Brazil. It was isolated Phytophthora sp. which pathogenicity was confirmed in the host seedlings. Morphological and physiological characteristics in carrot-agar modified medium were consistent with Phytophthora nicotianae description. The PCR sequences products obtained with ITS1/ITS4 primers were compared to sequences of ribosomal DNA of Phytophthora species from the GenBank database observing high identity with other P. nicotianae isolates. A phylogenetic tree was performed to compare the isolate with other sequences of P. nicotianae, which clustering has been verified with 99% of bootstrap, confirming the morphophysiological studies. This... |

| This paper reports for the first time in the Cerrado region of Brazil the occurrence of white mold caused by Sclerotinia sclerotiorum in coriander (Coriandum sativum), parsley (Petroselinum crispum) and Peruvian carrot (Arracacia xanthorrhiza). The disease was observed on coriander, in Cristalina, Goiás State, on parsley in Gama, the Federal District and on Peruvian carrot in Ibiá, Minas Gerais State. Pathogenicity tests demonstrated that the fungus S. sclerotiorum is the causal agent of the observed symptoms in these plants. The three isolates obtained from naturally infected plants were inoculated in coriander (cv. Verdão), parsley (cv. Lisa Gigante), Peruvian carrot (cv. Amarela de Senador Amaral) and carrot (cv. Forto Nantes) and they were pathogenic... |
