ABSTRACT
As doenças inflamatórias intestinais (DIIs) compreendem, principalmente, a doença de Crohn (DC) e a retocolite ulcerativa (RU), ambas idiopáticas, porém relacionadas a uma resposta imunológica anormal à microbiota bacteriana da luz intestinal. Na RU a inflamação é difusa, restrita à mucosa e inespecífica, com comprometimento contínuo da parede, principalmente do reto, enquanto na DC as lesões são descontínuas, podem comprometer todas as camadas da parede e afetar qualquer parte do trato gastrointestinal. O quadro clínico é comum e compreende diarreia, febre e dores abdominais, podendo cursar também com manifestações extraintestinais. O diagnóstico é feito através dos dados clínicos, achados radiológicos e histológicos, sem haver, no entanto, nenhuma característica que isoladamente feche o diagnóstico de DII específica.
Inflammatory bowel diseases (IBDs) comprise mainly Crohn?s disease (CD) and ulcerative colitis (UC), both are idiopathic but believed to be related to an abnormal immune response to bacterial microbiota in the intestinal lumen. In RU diffuse inflammation is restricted to the mucosa and is nonspecific, with continued commitment that stars at rectum?s wall. In DC, the injuries are discontinuous, involve all layers of the intestinal wall and can affect any part of the gastrointestinal tract. The clinical picture of both is diarrhea, fever, abdominal pain, and may present with extraintestinal manifestations. The diagnosis is made by the junction of clinical, radiological and histological findings, without having, however, a feature alone that leads to a diagnosis of a specific IBD.

The objective of this study was to investigate the growth of juvenile fat snook (Centropomus parallelus) in laboratory conditions when fed a diet supplemented with the probiotic Lactobacillus plantarum. Changes in the intestinal flora, haematological parameters and growth performance were assessed using 180 fishes (54.2 ± 13.4 g each). The fishes were subjected to two treatments divided into six cages: 1) feed supplemented with probiotic, and 2) feed without probiotic (control). The temperature, dissolved oxygen and salinity were maintained at 25 ± 1 ° C, 4.0 mg.L-1 and 33 , respectively. After 10 weeks of culture, the fishes fed probiotic had reduced viable culturable heterotrophic bacteria and Vibrio spp. and increased lactic acid bacteria in the intestinal tract, as well as a higher number of thrombocytes, leukocytes and lymphocytes in the blood. No significant difference was observed in the growth, survival or body composition, but the hepatosomatic index was significantly higher in the fishes fed with probiotic and control.
ABSTRACT
The stable fly, Stomoxys calcitrans, has a great importance in medical and veterinary health due to its feeding and reproductive habits, which can disseminate some pathogenic agents among hosts even at long distances. This study aimed to describe, for the first time in Brazil, the bacterial microbiota in segments of the stable fly. Bacterial species were isolated from three different segments (cuticle, mouth parts and abdominal alimentary tract) of the stable fly. Twenty dairy farms were visited in four municipalities: Barra Mansa, Quatis, Resende and Rio Claro in the State of Rio de Janeiro in order to collect 20 flies in each site. Dissection of the flies and procedures of isolation and identification of bacterial species were performed. A total of 161 colonies of 33 distinct species were isolated, such as Escherichia coli, Staphylococcus aureus, and S. intermedius. Stomoxys calcitrans may harbor bacterial agents on their cuticle, mouth parts and abdominal alimentary tract and these bacteria may be pathogenic to their hosts.
A mosca dos estábulos, Stomoxys calcitrans, possui grande importância médica e veterinária devido a seus hábitos alimentares e reprodutivos, visto que pode disseminar agentes patogênicos para hospedeiros, mesmo a longas distâncias. Esse estudo teve por objetivo, pela primeira vez no Brasil, descrever a microbiota bacteriana de segmentos da mosca dos estábulos. As espécies bacterianas foram isoladas de três diferentes segmentos (superfície externa, aparelho bucal e trato digestivo abdominal) de S. calcitrans. Foram visitadas 20 fazendas leiteiras em quatro municípios: Barra Mansa, Quatis, Resende e Rio Claro no Estado do Rio de Janeiro para coletar 20 moscas em cada uma delas. A dissecção das moscas e os procedimentos de isolamento e identificação bacteriana foram realizados. Um total de 161 colônias de 33 espécies distintas foi isolado, dentre elas Escherichia coli, Staphylococcus aureus e S. intermedius. Stomoxys calcitrans pode veicular agentes bacterianos presentes na superfície externa, aparelho bucal e trato digestivo abdominal e essas bacterias possuem potencial patogênico a diversos hospedeiros deste muscídeo.
