Bacterial flora of liver abscesses in feedlot cattle fed tylosin or no tylosin. (1/293)

Bacterial flora of liver abscesses from cattle fed tylosin or no tylosin and susceptibilities of the predominant bacterial isolates to tylosin and other antimicrobial compounds were determined. Abscessed livers were collected at slaughter from cattle originating from feedlots that had fed tylosin (n = 36) or no tylosin (n = 41) for at least 2 yr, and segments of livers with one or two intact abscesses were transported to the laboratory. Abscesses were cultured for anaerobic and facultative bacteria. Fusobacterium necrophorum, either as single culture or mixed with other bacteria, was isolated from all abscesses. The incidence of subsp. necrophorum, as part of the mixed infection, was lower (P < .05) in the tylosin group than in the no-tylosin group (33 vs 61%). However, the incidence of Actinomyces pyogenes was higher (P < .01) in the tylosin group than in the no-tylosin group (53 vs 10%). Totals of 119 F. necrophorum and 21 A. pyogenes isolates were used for determinations of susceptibilities to bacitracin, oxytetracycline, chlortetracycline, lasalocid, monensin, tylosin, tilmicosin, and virginiamycin. The minimum inhibitory concentrations (MIC) of antibiotics were determined with a broth microdilution method. The mean MIC of tylosin for F. necrophorum and A. pyogenes were not different between isolates from tylosin and no-tylosin groups. We concluded that continuous feeding of tylosin did not induce resistance in F. necrophorum or A. pyogenes. Also, the higher incidence of mixed infection of F. necrophorum and A. pyogenes in liver abscesses of tylosin-fed cattle suggests a potential synergistic interaction between the two organisms in causing liver abscesses.  (+info)

Analysis by enzyme-linked immunosorbent assay and PCR of human liver abscess aspirates from patients in China for Entamoeba histolytica. (2/293)

Aspirates of liver abscesses were analyzed for Entamoeba histolytica. PCR detected a gene encoding a 30-kDa protein in all samples but detected the ribosomal DNA gene in only 14 (33.3%) samples. Enzyme-linked immunosorbent assay detected antigen in 41 (97.6%) samples. PCR analysis of a strain-specific antigen (SSG) revealed that abscesses were caused by various strains.  (+info)

Identification of a major cluster of Klebsiella pneumoniae isolates from patients with liver abscess in Taiwan. (3/293)

Klebsiella pneumoniae has emerged as the leading liver abscess pathogen in Taiwan, with the percentage rising from 30% in the 1980s to over 80% in the 1990s. Most of the patients with K. pneumoniae liver abscess are diabetic and without biliary tract disease. Some patients develop serious extrahepatic complications such as endophthalmitis, meningitis, lung abscess, and necrotizing fasciitis. Pulsed-field gel electrophoresis (PFGE) was used for cluster analysis of 96 isolates from patients with liver abscess and 60 isolates from patients with other diseases. A total of 136 PFGE types were identified. Among the 96 liver abscess-associated isolates, 60 (62.5%) were classified in major cluster A. Cluster A included 41 PFGE types (types 1 to 41) which had a genetic similarity of at least 72.4% +/- 9.4%. The PFGE patterns of cluster A strains are so similar that they could have originated from the same ancestor. This study demonstrates that cluster A plays an important role in the high incidence of K. pneumoniae liver abscess in Taiwan.  (+info)

Multilocular pyogenic hepatic abscess complicating ascaris lumbricoides infestation. (4/293)

A 74-year-old man was admitted to our hospital with frequent right flank pain. The multiple multilocular hepatic abscesses were revealed by computed tomography. Radiographs following a barium meal showed a linear filling defect in the ileum consistent with ascariasis. One day after treatment with pyrantel pamoate, an Ascaris was passed in the stool. The pyogenic hepatic abscesses gradually healed with both antibiotics and continuous drainage. After 2 months, he was discharged. In this case, the pyogenic hepatic abscesses were thus considered to have been caused by an inflammation which spread through the portal vein.  (+info)

Chromobacterium violaceum infection in Brazil. A case report. (5/293)

We report the second case of infection with Chromobacterium violaceum that occurred in Brazil. A farm worker living in the State of Sao Paulo presented fever and severe abdominal pain for four days. At hospitalization the patient was in a toxemic state and had a distended and painful abdomen. Chest X-ray and abdominal ultrasound revealed bilateral pneumonia and hypoechoic areas in the liver. The patient developed failure of multiple organs and died a few hours later. Blood culture led to isolation of C. violaceum resistant to ampicillin and cephalosporins and sensitive to chloramphenicol, tetracyclin, aminoglicosydes, and ciprofloxacin. Autopsy revealed pulmonary microabscesses and multiple abscesses in the liver. The major features of this case are generally observed in infections by C. violaceum: rapid clinical course, multiple visceral abscesses, and high mortality. Because of the antimicrobial resistance profile of this Gram-negative bacillus, for appropriate empirical antibiotic therapy it is important to consider chromobacteriosis in the differential diagnosis of severe community infections in Brazil.  (+info)

Unretrieved gallstones presenting as a Streptococcus bovis liver abscess. (7/293)

We describe a case of a delayed liver abscess presenting two years after a laparoscopic cholecystectomy. At exploration, the patient was found to have an unretrieved gallstone as the nidus for the Streptococcus bovis abscess.  (+info)

Isolated tuberculous hepatic abscess in a non-immunocompromised patient. (8/293)

A 38 years old female presented with pain in the epigastrium, jaundice and fever since one and half month. The computerised tomographic scan of the abdomen revealed a multiloculated abscess of the left lobe of liver. The pus drained from the liver abscess at laparotomy showed acid fast bacilli on microscopy. A detailed search failed to identify any other focus of tuberculous infection. The case has been reported for the rarity of isolated hepatic tuberculous abscess and its presentation with jaundice, a rare feature, and to highlight the importance of microscopic or culture diagnosis in a suspected case of pyaemic abscess.  (+info)
