A Síndrome Multissistêmica do Definhamento do Suíno (SMDS) é uma doença emergente e mundialmente distribuída, que tem trazido sérios prejuízos econômicos para a indústria suinícola. O Circovírus Suíno tipo 2 (PCV2), agente causal da doença, provoca lesões principalmente nos tecidos linfóides, e sugere-se que produza imunossupressão, predispondo o hospedeiro a infecções virais, bacterianas e fúngicas secundárias. Neste trabalho, é descrito um estudo da prevalência e bacteriologia das otites purulentas em suínos apresentando a SMDS, bem como em animais de baixo desenvolvimento e de crescimento normal. No total, foram examinados 385 suínos com idades entre 60 e 130 dias. De 242 animais com a SMDS, 57 (23,5%) apresentaram lesões purulentas no ouvido médio. Dentre 119 animais de baixo desenvolvimento, apenas 1 (0,7%) apresentou a lesão. Não foram detectadas lesões macroscópicas no ouvido médio dos 24 animais com crescimento normal (controles). Os agentes isolados com maior freqüência das lesões foram Arcanobacterium pyogenes, Streptococcus α– hemolíticos e Pasteurella multocida, encontrados em, respectivamente, 37 (43%), 32 (37,2%) e 24 (27,9%) dos 86 ouvidos submetidos à bacteriologia. A alta prevalência de lesões purulentas no ouvido médio de animais com a SMDS sugere que a infecção pelo PCV2 pode tornar o suíno mais suscetível às otites bacterianas. Por outro lado...

Bacterial strains isolated from the kidney and liver of grey mullets, Mugil platanus Giinther, 1880, captured in Cananéia, São Paulo State, Brazil, in October 1996, belong to the genera Micrococcus, Pseudomonas, Flavobacterium, Aeromonas and Vibrio. The resistance/susceptibility patterns of the isolated micro-organisms to nine antimicrobial substances were determined, the more resistant bacteria had been Pseudomonas, Flavobacterium and Micrococcus. To the best of the authors knowledge this is the first bacteriological study done on Mugil platanus in Brazil.

OBJECTIVE: Treatment of perianal abscesses requires prompt surgical drainage and antimicrobial therapy. However, we should encourage the selective use of antimicrobial agents on a case-by-case basis, especially because there is no evidence that uncomplicated perianal abscesses can be safely treated only with drainage. For this reason, it is important to identify the causative organisms; therefore, we accessed the microbiological analysis of these patients. PATIENTS AND METHODS: In this study, 81 consecutive adult patients with perianal abscesses, who presented at a university hospital in Diyarbakir from January 2004 to December 2006, were included. Clinical and laboratory data, and results of microbiological analysis were recorded. RESULTS: All specimens, except seven, yielded bacterial growth. Escherichia coli, Bacteriodes spp., coagulase-negative Staphylococci, and Staphylococcus aureus were the most common isolated organisms. CONCLUSION: In contrast to other investigators, this study demonstrated that aerobic organisms are the predominant isolates in these infections.

Duodenum swabs were harvested from 80 broilers in 15 flocks of 8 broiler farms and were submitted to bacteriological evaluation. Five broiler breeders were sampled to obtain comparative data. Macro and microscopic lesions in the gut and the liver were evaluated in all birds submitted to swab harvesting and also broilers of two slaughter plants. Semiquantitative bacterial examination in duodenum swabs demonstrated higher microorganism growth in blood agar than in MacConkey medium. Staphylococcus sp, Enterococcus sp and Escherichia coli were found in some broiler flocks. An increased cellularity of the muscular mucosae of duodenum villi and/or the presence of some gametocytes or schizonts of coccidia were found in the lesioned gut in addition to high bacterial growth in blood agar. In some flocks, enlarged yellowish livers with vacuolated hepatocytes and/or increased reticuloendothelial response were seen in some birds. Liver and gut samples were collected in two slaughter plants in order to establish a pattern of response in broilers after withdrawal of growth promoters. Livers with macroscopic lesions presented microscopic lesions in the parenchyma such as increased leukocyte response in the sinusoidal space, vacuolar degeneration of hepatocytes or focal necrosis in the perilobular region...

Accurate antimicrobial susceptibility testing is vital for patient care and surveillance of emerging antimicrobial resistance. The National Committee for Clinical Laboratory Standards (NCCLS) outlines generally agreed upon guidelines for reliable and reproducible results. In January 1997 we surveyed 320 laboratories participating in the New York State Clinical Evaluation Program for General Bacteriology proficiency testing. Our survey addressed compliance with NCCLS susceptibility testing guidelines for bacterial species designated a problem (Staphylococcus aureus and Enterococcus species) or fastidious (Streptococcus pneumoniae, Haemophilus influenzae, and Neisseria gonorrhoeae) organism. Specifically, we assessed compliance with guidelines for inoculum preparation, medium choice, number of disks per plate, and incubation conditions for disk diffusion tests. We also included length of incubation for S. aureus and Enterococcus species. We found overall compliance with the five characteristics listed above in 80 of 153 responding laboratories (50.6%) for S. aureus and 72 of 151 (47.7%) laboratories for Enterococcus species. The most common problem was an incubation time shortened to less than 24 h. Overall compliance with the first four characteristics was reported by 92 of 221 (41.6%) laboratories for S. pneumoniae...

During a 2-year period, 10 strains of Arthrobacter cumminsii were isolated in or received by a Swiss routine clinical bacteriology laboratory, and 5 further isolates were referred to a Swedish bacteriology reference center over a 5-year period, making A. cumminsii the most frequently encountered Arthrobacter species in these two laboratories. The present report outlines the clinical features of the 15 A. cumminsii strains and presents an extended biochemical characterization of this microorganism. A. cumminsii exhibits a unique cellular fatty acid pattern with the consistent presence of C14:0i and C14:0 fatty acids as well as relatively large amounts of C16:0i and C16:0 fatty acids usually not seen in other Arthrobacter spp. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis was found to be a useful tool for confirmation of the identification of A. cumminsii. The MICs of 39 antimicrobial agents were determined, and it was demonstrated that aminoglycosides and quinolones had only weak activities against A. cumminsii strains, in contrast to their activities against most other coryneform bacteria. As a result of the extended characterization of A. cumminsii, an emended description of this species is presented. Due to the lack of A. cumminsii in established identification systems...

A medium containing (per liter) 6.8 g of sodium acetate trihydrate, 3.4 g of potassium dihydrogen phosphate, and 0.1 g of magnesium sulfate heptahydrate (medium pH, 5.85 plus/minus 0.05) was developed for use in a water bacteriology proficiency test. The medium maintained 80 to 100 % viability of inoculated Escherichia coli at temperatures up to 31 degrees C for at least 12 days, while the concentrations of bacteria in the medium were as low as 20 bacteria per 100 ml. The medium remained stable after a year of storage. It has been used successfully to preserve bacteria in nine statewide bacteriology proficiency tests for potable and nonpotable water and has also been used in a nationwide pilot test. This report presents the results of these tests.

A dedicated microbiology data processing system with remote batched job entry to an obsolete computer, has been superseded by the inclusion of bacteriology in an on-line interactive clinical pathology system which had previously incorporated chemical pathology and haematology. The original Phoenix system has been adapted to allow for the entry of bacteriology data using mnemonic codes and to deal with the problems caused by the longer processing time of bacteriology specimens. Particular advantages of the new system include the immediate linkage of all specimens for each patient and an easy recall and display of results in the laboratories and on the wards.

The bacteriology of anorectal sepsis in a district general hospital has been reviewed to see whether the information gained helped patient management. Forty-six patients with anorectal sepsis were reviewed, underlying fistulas were identified in nine patients (19.5%). Bacteroides species were not routinely subtyped in the department. It was found that isolation of unspecified Bacteroides species was not helpful in identifying those patients with underlying fistulas. Unless subtyping of Bacteroides species is specifically requested, pus from anorectal sepsis should not routinely be sent for bacteriology.

In previous studies of human and experimental acute pancreatitis, three main assumptions have been made. First, that the disease is due to activation of pancreatic proteolytic enzymes in the pancreas with resulting “autodigestion” of the gland. Second, that interstitial pancreatitis is a mild form of hemorrhagic pancreatitis into which it may progress, and third, that bacteria play little part, if any, in the initiation of the disease. These assumptions are now questioned. In the present study in dogs, levels of proteolytic enzymes in blood, thoracicduct lymph and peritoneal fluid were measured using benzoylarginine amide. Raised levels of amidase were found in hemorrhagic, but not with interstitial, pancreatitis, and biochemical examination of amidase suggested it was not a pancreatic protease, but with its broad specificity and stability derived from bacteria. Addition of antibiotic to the blind duodenal loop in hemorrhagic pancreatitis reduced the level of blood amidase, but Trasylol given intravenously did not, nor did it inhibit amidase in vitro. In all animals, histological examination was made of the pancreas at time of death. On bacteriology, it is concluded that experimental interstitial pancreatitis results from damage to the pancreatic duct system without infection...

The organisms cultured and their antibiotic sensitivities, together with clinical details, were obtained from all the available bacteriology requestlresult forms from a rural practice over a six-year period. The 3022 bacteriology specimens analysed yielded 997 potential pathogens. The main infections studied were those of the urinary tract, the upper respiratory tract and the skin and soft tissue. In spite of the fact that trimethoprim alone had never been used in the practice, 29% of urinary tract pathogens were resistant to this drug. Ninety-six per cent of isolates of Haemophilus influenzae were sensitive to ampicillin. The overall results suggest that most infectious disease in rural general practice can be managed with a limited and inexpensive antibiotic regimen. Such a regimen is described.

AIMS—To determine the current bacteriology of lacrimal duct obstruction (LDO) and to relate the bacteriological findings to the type of symptoms.
METHODS—127 samples were obtained from the lacrimal sac in 118 consecutive adult patients with LDO, including nine bilateral cases.
RESULTS—Altogether, 156 isolates were recovered from the 127 samples cultured. Cultures were positive from 84% of the samples. Gram positive bacteria were isolated in 79 (62%) samples. The most frequently cultured bacterial species was Staphylococcus epidermidis, representing 27% of the isolates. Gram negative bacteria were recovered from 26 (20%) samples, and these bacteria were statistically significantly more common in cases with copious discharge than in cases with minor discharge (p=0.000). Cases with simple stenosis of the lacrimal duct (SSLD) showed significantly less Streptococcus sp (p=0.004) and Gram negative organisms (p=0.004) than those with chronic dacryocystitis.
CONCLUSION—The bacteriology of SSLD resembles that of normal conjunctival flora. Chronic dacryocystitis in adults is associated with an increased proportion of Gram negative bacteria which may be a reservoir for postoperative intraocular infection. They should also be taken into account in selecting antimicrobial prophylaxis in lacrimal drainage surgery.

Clinical microbiology has always been a slowly evolving and conservative science. The sub-field of bacteriology has been and still is dominated for over a century by culture-based technologies. The integration of serological and molecular methodologies during the seventies and eighties of the previous century took place relatively slowly and in a cumbersome fashion. When nucleic acid amplification technologies became available in the early nineties, the predicted "revolution" was again slow but in the end a real paradigm shift did take place. Several of the culture-based technologies were successfully replaced by tests aimed at nucleic acid detection. More recently a second revolution occurred. Mass spectrometry was introduced and broadly accepted as a new diagnostic gold standard for microbial species identification. Apparently, the diagnostic landscape is changing, albeit slowly, and the combination of newly identified infectious etiologies and the availability of innovative technologies has now opened new avenues for modernizing clinical microbiology. However, the improvement of microbial antibiotic susceptibility testing is still lagging behind. In this review we aim to sketch the most recent developments in laboratory-based clinical bacteriology and to provide an overview of emerging novel diagnostic approaches.

Bacteriology and histopathology are the most commonly used tests used for official confirmatory diagnosis of bovine tuberculosis (bTB) in cattle in most countries. PCR is also being used increasingly because it allows a fast diagnosis. This test could be applied as a supplement to or replacement for current bTB confirmatory diagnostic tests but its characteristics have first to be evaluated. The aim of this study was to estimate and compare sensitivities and specificities of bacteriology, histopathology and PCR under French field conditions, in the absence of a gold standard using latent class analysis. The studied population consisted of 5,211 animals from which samples were subjected to bacteriology and PCR (LSI VetMAX™ Mycobacterium tuberculosis Complex PCR Kit, Life Technologies) as their herd of origin was either suspected or confirmed infected with bTB or because bTB-like lesions were detected during slaughterhouse inspection. Samples from 697 of these animals (all with bTB-like lesions) were subjected to histopathology. Bayesian models were developed, allowing for dependence between bacteriology and PCR, while assuming independence from histopathology. The sensitivity of PCR was higher than that of bacteriology (on average 87.7% [82.5–92.3%] versus 78.1% [72.9–82.8%]) while specificity of both tests was very good (on average 97.0% for PCR [94.3–99.0%] and 99.1% for bacteriology [97.1–100.0%]). Histopathology was at least as sensitive as PCR (on average 93.6% [89.9–96.9%]) but less specific than the two other tests (on average 83.3% [78.7–87.6%]). These results suggest that PCR has the potential to replace bacteriology to confirm bTB in samples submitted from suspect cattle.

Le développement et la survie de l’embryon dépendent des nutriments fournis par les sécrétions utérines. Les objectifs de cette étude étaient de déterminer l’effet de la surovulation (SOV) sur la bactériologie et cytologie utérine et sur les paramètres biochimiques utérin et sérique et leurs effets sur le nombre d’embryons transférables (ET). Deux groupes de vaches Holstein (groupe I, non lactante, n=7 et groupe II, lactante, n=28) ont été respectivement induites en chaleur ou surovulées et ensuite inséminées. Au jour 7 du cycle œstral (J7) et lors du jour de la récolte (JR), un prélèvement individuel de sang et de liquide de lavage utérin a été fait pour l’analyse du statut bactériologique et cytologique de l’utérus et la mesure de la concentration de plusieurs paramètres biochimiques présélectionnés. Les embryons récoltés ont été évalués selon les critères de l’IETS. La SOV a donnée une moyenne de 7.39 ± 6.22 ovocytes/embryons dont 3.32 ± 4.81 ET. Il n’y avait pas de variation significative de la bactériologie et cytologie utérine des deux groupes entre J7 et JR. La concentration sérique de l’urée (P=0.0001), d’E2 (P=0.006); la concentration utérine du Glu (P=0.002)...

This thesis traces the development of American bacteriology during the first quarter of the twentieth century. While bacteriology experienced a period of rapid growth, an enduring disciplinary anxiety equally characterized the field. In particular, bacteriologists feared increasing specialization and conceptual fragmentation. Leading practitioners repeatedly worried that their science constituted a collection of unrelated techniques, carried out in the service to other practical endeavors without the benefit of an underlying theory or unifying language. I suggest that the sources of bacteriology's rapid professional growth equally accounted for this sense of conceptual impoverishment and disciplinary privation. Typically, bacteriologists focused on what bacteria did rather than what they were in any biological sense. The first three chapters provide a comprehensive survey of the institutional contexts bacteriology (e.g., medical schools, public health laboratories, water sanitation works, dairies, land-grant colleges, and agricultural experiment stations). For the most part, bacteriologists studied bacteria only so far as to isolate, identify and eliminate pathogens. Dairy and soil bacteriologists, however, sought to distinguish productive types of bacteria...

The Ministry of Health requires that all medical laboratories in the Province of Ontario participate in a laboratory proficiency testing program (LPTP). In bacteriology compliance has been excellent. Eighty-six laboratories, for various reasons over the period under review, have surrendered their licence or, because of poor performance on LPTP test surveys, have had their licence withdrawn by the Ministry. The highest percentage of withdrawals occurred in small hospitals in isolated areas. In April 1979 there were 249 participating laboratories. Participants' results are first analysed by computer, and, subsequently, approximately 20% of participants' reports are reviewed by the Committee. Various Committee actions ensue: correspondence with the laboratory director regarding errors; an offer of a visit; and possibly a report via a senior LPTP committee to the Ministry that a laboratory is non-proficient and, in LPTP's terms of reference, non-remediable. Subsequent Ministry action might be the withdrawal of a laboratory's licence. However, this last recourse only occurs when educational efforts have proved ineffectual. Overall, performance in LPTP bacteriology surveys has improved over the period 1975-8, with 68% of 263 laboratories achieving a score of 70% or higher and 26% of 263 laboratories scoring less than 60%.

During the last five years, 48 graduates have taken the formal Diploma in Bacteriology course offered by the School of Hygiene, University of Toronto. This course provides instruction by lectures, seminars, and practical work in bacteriology, virology, immunology, parasitology, sanitary bacteriology, and statistics. A graduate course of this type presents many advantages as it is possible to cover a considerable area of knowledge in the relatively short space of one academic year. Of the 48 students, 23 held degrees in medicine, and 25 in veterinary science, arts, or science. Eleven diplomates continued further formal studies by enrolling in Master's or Ph.D. programs. Twenty diplomates are now engaged in university teaching in Canada or overseas. Almost all of the remaining 28 are employed in hospital, public health, or veterinary laboratories.

Laboratory investigation of bacterial infections generally takes two days: one to grow the bacteria and another to identify them and to test their susceptibility. Meanwhile the patient is treated empirically, based on likely pathogens and local resistance rates. Many patients are over-treated to prevent under-treatment of a few, compromising antibiotic stewardship. Molecular diagnostics have potential to improve this situation by accelerating precise diagnoses and the early refinement of antibiotic therapy. They include: (i) the use of 'biomarkers' to swiftly distinguish patients with bacterial infection, and (ii) molecular bacteriology to identify pathogens and their resistance genes in clinical specimens, without culture. Biomarker interest centres on procalcitonin, which has given good results particularly for pneumonias, though broader biomarker arrays may prove superior in the future. PCRs already are widely used to diagnose a few infections (e.g. tuberculosis) whilst multiplexes are becoming available for bacteraemia, pneumonia and gastrointestinal infection. These detect likely pathogens, but are not comprehensive, particularly for resistance genes; there is also the challenge of linking pathogens and resistance genes when multiple organisms are present in a sample. Next-generation sequencing offers more comprehensive profiling...

The origin of Bacteriology in Chile is intimately bound to the life of the physicians Vicente Izquierdo Sanfuentes and Francisco Puelma Tupper. Both were awarded in 1874 with a government fellowship to study in the most prestigious universities of Europe. Dr. Izquierdo studied Histology and Dr. Puelma Tupper Pathology. After their return to Chile in 1879, both founded in the Faculty of Medicine of the University of Chile, the first experimental laboratories in their respective disciplines. It was in those laboratories that the new science of microbiology started to be developed slowly. This discipline was just consolidating itself in Europe, led by the famous scientists Louis Pasteur and Robert Koch.
