ABSTRACT

Pathogenic microorganisms can reside transiently or permanently in the gallbladder of cattle. Thus, during slaughter, more attention should be given to the gastrointestinal tract, especially to the accessory organ, the gallbladder. The main aim of this study was to characterize the bacterial microbiota present in bile and gallbladder epithelium of cattle slaughtered in a slaughtering plant under sanitary conditions and to evaluate the antimicrobial resistance in strains of the genus Staphylococcus. Thirty intact gallbladders were collected and the in bile and epithelium were researched for the presence of Aerobic Mesophilic Heterotrophic Bacteria (AMHB), Staphylococcus spp., total Enterobacteriaceae, Enterococcus spp. and Salmonella spp.The frequency of isolation of the microorganism mentioned above were, respectively: 23.02 percent, 14.39 percent, 13.67 percent, 24.46 percent, 0 percent and 24.46 percent. Concerning both gallbladder environments, the frequency of isolation of the microorganisms in the epithelium was 64.03 percent, and in the bile 35.97 percent, with no statistical difference, but with significant difference between the population averages. In antimicrobial susceptibility testing, strains of Staphylococcus from both bile and gallbladder epithelium showed sensitivity to the antimicrobials: penicillin G, ceftriaxone, chloramphenicol and gentamicin. The observation that the gallbladder supports a high frequency of microorganisms brings us to the possible fact that cattle might be a persistent carrier of pathogens of great importance to public health...


Microrganismos patogênicos podem residir temporariamente ou permanentemente na vesícula biliar de bovinos. Assim, durante o abate, maior atenção deve ser dada ao trato gastrointestinal, especialmente para o órgão acessório, a vesícula biliar. O principal objetivo deste estudo foi caracterizar a microbiota bacteriana presente na bile e no epitélio de vesículas biliares de bovinos abatidos em matadouro frigorífico sob inspeção sanitária e avaliar a resistência antimicrobiana de estirpes do gênero Staphyloccocus. Foram coletadas 30 vesículas biliares íntegras e foi pesquisada na bile e no epitélio do órgão a presença de bactérias heterotróficas aeróbias mesófilas (BHAM), Staphylococcus spp. e Enterobacteriaceae totais, Escherichia coli, Enterococcus spp. e Salmonella spp. A frequência de isolamento dos microrganismos citados acima foi, respectivamente: 23,02 por cento, 14,39 por cento, 13,67 por cento, 24,46 por cento, 0por cento e 24,46 por cento. Em relação aos dois ambientes da vesícula, a frequência de isolamento dos microrganismos no epitélio foi de 64,03 por cento, e na bile 35,97 por cento, não sendo diferente estatisticamente, mas com diferença significativa entre as médias populacionais.No teste de susceptibilidade aos antimicrobianos, as estirpes de Staphylococcus isoladas a partir da bile e do epitélio da vesícula biliar apresentaram sensibilidade a: penicilina G, ceftriaxona, cloranfenicol e gentamicina. A observação de que a vesícula biliar comporta microrganismos em elevadas frequências atenta para o fato de que o bovino possa ser um portador persistente de patógenos de grande importância em saúde pública...

ABSTRACT

Earlier reports on the detection of Heticobocter DNA in the gallbladder tissue of patients with biliary diseases have shown discordant results. This study aimed to detect the presence of Helicobacter in gallstone, gallbladder tissue and bile specimens from subjects with H. pylori-positive gastritis with cholelithiasis. The presence of H. pylori in antrum biopsies was confirmed by rapid urease test and/or histopathological examination. DNA was extracted from gallbladder, bile and gallstone samples from 50 patients undergoing cholecystectomy. The presence of Helicobacter genus-specific DNA [16S rRNA genes] was determined by nested polymerase chain reaction assay. Helicobacter DNA was detected in the gallbladder tissue and bile of 28% and 18% respectively of the patients, but was not detected in any of the gallstones. These results do not rule out the possibility of Helicobacter infection as a contributing agent or cofactor in the development of biliary diseases

ABSTRACT

PURPOSE: Establish the prevalence of Helicobacter spp in chronic cholecystitis and its correlation with the gallbladder's histological findings. METHODS: 100 patients were operated for chronic cholecystitis with cholecystolithiasis. In pathological examination of the gallbladder, were evaluated the presence of metaplasia, dysplasia, lymphoid follicles, anaplasia and tumors that might be related to the presence of Helicobacter plus the presence of the bacilli Giemsa by optical microscopy. From the DNA extracted from the gallbladder's bile, PCR was performed by using specific primers for the identification of Helicobacter spp with amplification of the 400bp segment of rRNA gene16S, with positive control DNA from Helicobacter pylori. All the cases negative for isolation of genetic material were excluded. The cases of PCR and Giemsa were used as negative control group. The histological findings were compared to the presence of bacilli and PCR data using a chi-square and Fisher's Exact test (CI = 95.0 percent, p <0.05). RESULTS: Of 68 patients, 42 (61.8 percent) were PCR for Helicobacter spp and 19 (27.9 percent) had Giemsa. There was no correlation between the two findings. The PCR for Helicobacter spp was not correlated to the histological findings. The presence of lymphoid follicles and metaplasia was related to the Giemsa (p = 0.025 and p= 0.039). CONCLUSION: There is high prevalence of Helicobacter spp in patients with chronic cholecystitis and cholecystolithiasis without be correlated with the histological patterns studied.


OBJETIVO: Estabelecer a prevalência do Helicobacter spp nos doentes com colecistopatia crônica calculosa e correlacioná-la com as alterações histológicas da vesícula biliar. MÉTODOS: Foram operados 100 doentes portadores de colecistite crônica calculosa. No anátomo-patológico foram avaliadas a presença de, metaplasias, displasias, folículos linfóides, anaplasias e tumores que pudessem se relacionar à presença do helicobacter e a presença de bacilos Giemsa à microscopia. A partir do DNA extraído da bile foi realizada PCR utilizando-se primers específicos para identificação de Helicobacter spp com amplificação de segmento de 400bp do gene16S rRNA, com controle positivo de DNA de Helicobacter Pylori. Os casos negativos para isolamento de material genético na bile foram excluídos. Os casos de PCR e Giemsa negativos foram utilizados como grupo controle. Os achados histológicos foram comparados ao Giemsa e à PCR utilizando-se Teste do Qui-Quadrado e Exato de Fisher (IC=95,0 por cento; p<0,05). RESULTADOS: De 68 doentes, 42(61,8 por cento) apresentaram PCR para Helicobacter spp e 19(27,9 por cento) Giemsa. Não houve correlação entre os dois achados. Não houve correlação entre alterações histológicas e a PCR (p=0,378). A presença de folículos linfóides e metaplasia estiveram relacionadas ao Giemsa (p=0,025 e 0,039). CONCLUSÃO: Há prevalência elevada de Helicobacter spp nos doentes com colecistite crônica calculosa sem haver correlação com os achados histológicos estudados.

ABSTRACT

OBJECTIVE: Helicobacter pylori (H pylori) represents a potential initiator of cholesterol crystallization and it has been proposed that it is related to gallstone formation. In this study, any possible association between the H pylori identification in the mucosa of gallbladder and cholesterol gallstone formation was evaluated. METHODS: Gallbladders containing pure or mixed cholesterol gallstones (cholelithiasis group, n = 89) and gallbladders without gallstones (control group, n = 42) were submitted to standard histopathological examination for H pylori detection, as well as to nested polymerase chain reaction amplification for H pylori DNA detection. RESULTS: Helicobacter pylori was identified in the gallbladder's epithelium in four patients with cholelithiasis and in two patients in the control group by histology. In all the cases which were found to be H pylori positive by histological examination, H pylori DNA were also detected. No correlation between gallstone formation and H pylori detection in the biliary epithelium was found. A higher incidence of acute inflammation in the cholelithiasis (22.5% vs 9.5%, p = not significant [ns]) and in the H pylori positive groups (33% vs 17.6%, p = ns) were histologically detected. A higher incidence (10% vs 0%), p = ns) of H pylori in gallbladders with gallstones and acute inflammation, compared to gallbladders with acute inflammation but without gallstones, was noticed. CONCLUSION: Helicobacter pylori is detectable in low frequency in the mucosa of the gallbladder and it does not seem to act as a lithogenic component for cholesterol gallstone formation. Its higher incidence in gallbladders with gallstones and acute inflammation, suggests a possible accessory role in a subset of patients with cholelithiasis.


OBJETIVO: Helicobacter pylori (H pylori) representa un iniciador potencial de la cristalización del colesterol, y se ha propuesto que guarda relación con la formación del cálculo biliar. En este estudio, se evaluó cualquier posible asociación entre la identificación de H pylori en la mucosa de la vesícula y la formación del cálculo biliar de colesterol. MÉTODOS: Las vesículas que contienen cálculos biliares de colesterol puros o mixtos (grupo de colelitiasis, n = 89) y vesículas sin cálculos biliares (grupo control, n = 42) fueron sometidos a un examen histopatológico estándar con el fin de detectar el H pylori descubrimiento, así como a la amplificación de la reacción en cadena de polimerasa para la detección de ADN H pilori. RESULTOS: El Helicobacter pylori fue identificado mediante histología en el epitelio de la vesícula en cuatro pacientes con el colelitiasis y en dos pacientes en el grupo de control. En todos los casos que resultaron ser H pylori positivo por el examen histológico, se halló también DNA H pylori. No se halló correlación ninguna entre la formación del cálculo biliar y la detección de H pylori en el epitelio biliar. Se detectó histológicamente una incidencia más alta de inflamación aguda en la colelitiasis (22.5% contra 9.5%, p = no significativo [ns]) y en los grupos H pylori positivos (33% contra 17.6%, p = ns). Se observó una incidencia más alta (10% contra 0%), p = ns) de H pylori en las vesículas con los cálculos biliares e inflamación aguda, en comparación con las vesículas con la inflamación aguda pero sin cálculos biliares. CONCLUSIÓN: Helicobacter pylori es detectable en baja frecuencia en la mucosa de la vesícula y no parece actuar como un componente litogénico en la formación del cálculo biliar de colesterol. Su mayor incidencia en las vesículas con cálculo biliar e inflamación aguda, hace pensar en un posible papel auxiliar en un subconjunto de pacientes con colelitiasis.

ABSTRACT

Background: Gallbladder cancer is frequent in Chile and there is sparse information about the association between this type of cancer and the presence of bacteria in the gallbladder bile. Aim: To determine the presence of aerobic bacteria in gallbladder bile in patients with and without gallbladder cancer. Material and methods: A microbiological analysis of bile and pathological study was performed in 608 gallbladders, obtained during to cholecystectomies performed to 513 women and 95 men aged 44 years old as a mean. Results: Pathological study showed a chronic cholecystitis in 468 cases (77 percent), an acute cholecystitis in 140 (33 percent), cancer in 24 (3.9 percent) and dysplasia in 5 cases (0.8 percent). A positive culture was obtained in 22.5 percent of women and 28.5 percent of males. Twenty seven percent of women over 30 years old had positive cultures compared with 10 percent of younger women (p <0.001). Thirty two percent of acute cholecystitis had positive cultures, compared with 24 percent of chronic cholecystitis (p=0.03). E Coli was isolated in 51 percent of positive cases, streptococci-enterococci in 24 percent, enterobacter sp in 9 percent, klebsiella and proteus in lower proportions. Salmonella sp was isolated in 4 cases, being all women with chronic cholecystitis. Thirteen of 29 cases with cancer or dysplasia had positive cultures (45 percent), compared with 25 percent of patients with inflammatory gallbladder diseases (p=0.02). streptococci-enterococci were isolated in 7 cases and enterobacter sp in three. Conclusions: The presence of salmonella sp in gallbladder bile was not frequent in the studied patients. Its role in the pathogenesis of gallbladder cancer must be reassessed

ABSTRACT

Com o objetivo de pesquisar em caes a presença de bactérias no sangue portal e seu papel como via de disseminaçao, realizou-se a investigaçao bacteriana do sangue da veia porta, da veia hepática esquerda, da bile da vesícula biliar e do tecido hepático. Foram empregados dezesseis caes (Canis familiaris), em jejum e com peso médio de 12,18 Kg. Todos os animais foram submetidos à laparotomia e as amostras de sangue, bile e tecido hepático colocados em meios líquidos com caldo de tripticaseína de soja, sendo depois semeados em placas de Petri, contendo meios enriquecidos e seletivos, a cada 48 horas, durante um período de 15 dias para bactérias aeróbias e 30 dias para bactérias anaeróbias. Nas culturas, houve o crescimento de bactérias aeróbias na bile vesicular em 3/16 (18,8 por cento) e no sangue portal em 1/16 (6,3 por cento), nao se observando o crescimento de bactérias anaeróbias. Em relaçao ao sangue da veia hepática esquerda e do tecido hepático, nao houve o isolamento de bactérias aeróbias e anaeróbias em todas as semeaduras realizadas. Nao foi possível verificar a disseminaçao bacteriana pelo sangue portal, pois as bactérias isoladas no sangue portal e na bile foram concontradas isoladamente e em caes diferentes.

ABSTRACT

Pretende-se atualizar os dados microbiológicos em colecistite aguda litásica identificando os microorganismos eventualmente presentes nesta situaçäo, bem como verificar o aspecto de açäo de algumas drogas antimicrobianas atualmente disponíveis. Com este objetivo, säo incluídos 22 doentes operados em regime de urgência, com diagnósticos pré-operatórios de colecistite aguda litiásica. A bile vesicular, colhida por punçäo no intra-operatório, foi semeada em preparados apropriados para o crescimento de germes aeróbios e de anaeróbios. Verificou-se crescimento bacteriano constituído exclusivamente de germes aeróbios, únicos ou associados. Dos germes identificados, houve predominância de Gram-negativso (75,0%). Entre os microorganismos mais freqüentemente identificados figuravam a Escherichia coli, a Klebsiela pneumoniae e o Streptococcus sp. Foram testados 16 antimicrobianos para Gram-negativos e 19 para Gram-positivos. Verificaram diferentes níveis de resistência bacteriana a cada uma destas drogas. As melhores respostas foram obtidas com o Cloranfenicol (Gram+) e com a Cefotaxima sódica e Pefloxacin (Gram-). A Escherichia coli, germe mais freqüente entre aqueles identificados, mostrou-se, mais vezes, sensível à Gentamicina, Pefloxacin, Cefotaxima sódica e Tobramicina. Conclui-se, ao cotejar com os dados disponíveis na literatura, que a microflora nestas situaçöes näo sofreu alteraçäo ao longo do tempo, porém, qualitativamente, há necessidade periódica de se avaliar a sensibilidade destes germes em relaçäo aos antimicrobianos em uso. Atualmente, os antimicrobianos acima relacionados parecem constituir as melhores opçöes terapêuticas frente a infecçöes agudas das vias biliares
