Relationship between clinical symptomatology on the isolation of Salmonella Gallinarum of japanese quail (Coturnix coturnix) / Relação entre a sintomatologia clínica no isolamento de Salmonella Gallinarum de codornas japonesas (Coturnix coturnix)

Salmonella Gallinarum is capable of causing high mortality in birds of the order Galliformes. This study aimed to relate the presence of clinical signs with the recovery of Salmonella Gallinarum from organs and c loacal swabs of Japanese quails (Coturnix coturnix) experimentally infected. A total of 70 female quails were housed in a pair per cage and divided in two groups (IG: quails inoculated with 1.5x106 CFU of Salmonella Gallinarum Nalr/mL and CG: control group). After the inoculation, birds were evaluated three times a day to verify the presence of clinical signs. Birds that presented ruffled feathers, eyes closed and remained quiet in the cage were removed for euthanasia, as well as the same number of birds from the inoculated groups that presented no clinical signs and from the control group. Cloacal swabbing was performed following euthanasia for the sampling of liver, spleen, caeca, ovarian follicles and lung for microbiological procedure. Quails with clinical signs and quails found dead presented positivity of 100%. While inoculated quails with no clinical signs presented a lower positivity (38.5%). Therefore, quails with septicemia caused by SG present clinical signs of the disease and the pathogen can be isolated and quantified in the organs.(AU)

Salmonella Gallinarum pode causar alta mortalidade em aves da ordem Galliformes. Objetivou-se neste estudo relacionar a presença de sinais clínicos com a recuperação de Salmonella Gallinarum de órgãos e swabs cloacais de codornas japonesas (Coturnix coturnix) experimentalmente infectadas. Um total de 70 codornas fêmeas foram alojadas em par por gaiola e divididas em dois grupos (IG: codornas inoculadas com 1,5x106 UFC de Salmonella Gallinarum Nalr / mL e CG: grupo controle). Após a inoculação, as aves foram avaliadas três vezes ao dia para se verificar a presença de sinais clínicos. As aves que se apresentaram com penas eriçadas, olhos fechados e permaneciam imóveis na gaiola foram removidas para a eutanásia, assim como o mesmo número de aves dos grupos inoculados que não apresentaram sinais clínicos e do grupo controle. O swab cloacal foi realizado após a eutanásia para a amostragem de fígado, baço, ceco, folículos ovarianos e pulmão para procedimento microbiológico. As codornas com sinais clínicos e as encontradas mortas apresentaram positividade de 100%, enquanto as codornas inoculadas sem sinais clínicos apresentaram menor positividade (38,5%). Portanto, codornas com septicemia causada por SG apresentam sinais clínicos da doença e o patógeno pode ser isolado e quantificado em diversos órgãos.(AU)

Isolation of Salmonella enterica subsp. enterica (O: 4, 5: i) and Salmonella enterica subsp. Typhimurium from free-living domestic pigeons (Columba livia) / Detecção de Salmonella enterica subsp enterica (O: 4, 5: i) e Salmonella enterica subsp. Typhimurium em pombo doméstico de vida livre (Columba livia)

The present study reports the isolation of Salmonella enterica in organs of free-living domestic pigeons. In the clinic examination, the presence of feces in the peri-cloacal and abdominal regions were observed, as well as symptoms such as cachexy, incoordination and opisthotonos. Before any therapeutic protocol was applied the bird died and a necropsy was then performed for the removal of spleen, liver, kidney and intestine for bacteriological examination and antibiotic sensitivity test. Salmonella enterica subsp.enterica (O:4,5:i-) and Salmonella enterica subsp. enterica serovar Typhimurium were isolated from the liver and intestine and the sensitivity test demonstrated that these strains are sensitive to several antibiotics...

O presente trabalho relata o isolamento de Salmonella enterica em órgãos de um pombo doméstico de vida livre. No exame clínico foi observada a presença de fezes pericloacal na região ventral, caquexia, incoordenação motora e opistótono. Antes de iniciar um protocolo terapêutico, a ave foi a óbito, e, em seguida, foi realizada uma necropsia para remoção do baço, fígado, rim e intestino para exame bacteriológico e teste de sensibilidade a antibióticos. Foi isolado Salmonella enterica subsp. enterica (O:4,5:i-) e Salmonella enterica subsp. enterica sorovar Typhimurium do fígado e intestino, e o teste de sensibilidade demonstrou que essas cepas são sensíveis a vários antimicrobianos...

Isolation of Salmonella spp. in captive Psittaciformes from zoos and a commercial establishment of Fortaleza, Brazil / Isolamento de Salmonella spp. em Psittaciformes de zoológicos e estabelecimento comercial de Fortaleza, Brasil

This study showed a low prevalence of Salmonella spp. in captive psittacines from zoos and a commercial establishment of Fortaleza. None of the isolated serotypes (S. Lexington, S. Saintpaul and S. Newport) have yet been reported in Amazona aestiva, Ara chloroptera or Melopsittacus undulatus. However, the fact that most birds presented negative for Salmonella spp. may not imply the absence of this pathogen in these birds, since the intermittent excretion is a well-known characteristic of this microorganism...

A manutenção de aves em cativeiro reúne condições que favorecem a disseminação de doenças infecciosas, sendo a Salmonella uma dessas doenças infecciosas que acomete os psitacídeos. Portanto o objetivo do presente estudo foi isolar e identificar Salmonella spp. em Psittaciformes mantidos em criatórios comerciais e conservacionistas da Região Metropolitana de Fortaleza. Para o estudo, foram coletados swabs cloacais de 182 psitacídeos clinicamente sadios. Os resultados mostraram que três psitacídeos avaliados (1,65%) foram positivos: Amazona aestiva (Salmonella Lexington), Ara chloroptera (Salmonella Saintpaul) e Melopsittacus undulatus (Salmonella Newport). De acordo com a literatura científica, não há registro desses sorotipos em psitacídeos. Esta pesquisa evidenciou uma baixa prevalência de Salmonella spp. em Psittaciformes mantidos em criatórios comerciais e conservacionistas da Região Metropolitana de Fortaleza...

[Video-assisted surgery for closure of persistent ductus arteriosus. Study in sheep and initial clinical experience]. / Cirurgia vídeo-assistida para fechamento de canal arterial persistente. Estudo em carneiros e experiência clínica inicial.

PURPOSE: The aim of this study was to analyse the effectiveness of patent ductus arteriosus (PDA) closure by the video-assisted thoracic surgery (VATS). METHODS: The technique was utilized in 6 newborn lambs firstly. Three to four small incisions (3 to 10mm) were used in each animal to permit the introduction of lung retractors, video equipment, dissectors and clip appliers. The procedure was accompanied by video monitoring and after the dissection, the PDA was closed by 2 titanium clips. Seven days after, the animals were sacrificed and submitted to pathological study. Based on this initial experience seven patients (ages between 17 and 108 months) were operated on with this technique. RESULTS: In lambs, we have some difficulty to retract the lung. Despite this fact the closure of PDA was successful and proved by pathologic study. In children the dissection of PDA was easier due to manual ventilation. The interruption of PDA using the proposed method was obtained in 4 patients, those with good relation between ductus diameter and clip size and defined by echocardiography and angiographic studies. CONCLUSION: The use of VATS for interruption of PDA in both, experimental and initial clinical experiences, has showed to be an effective method.
