Microscopy of clinical specimens is a rapid and inexpensive method for the presumptive diagnosis of certain infectious diseases. Early diagnosis permits the physician to initiate appropriate therapy without waiting for culture results. Examination of the Gramstained smear gives information on the inflammatory response, as well as the bacteria involved. Accurate interpretation of the smear, however, requires some training and experience. This article describes the microscopic methods commonly used in the laboratory and their application to office practice...

BACKGROUND: urinary tract infection is a common problem during pregnancy. Asymptomatic bacteriuria can cause the development of serious complications affecting both the mother and foetus. Urine culture, the traditional screening test is relatively expensive, time consuming and requires a microbiology laboratory and trained staff. However simpler, less expensive tests which include urine multistix and urine gramstain better suited for developing countries are available. OBJECTIVE: to determine the sensitivity, specificity and predictive values of multistix nitrite, leucocyte esterase (LE) and urine gram staining for asymptomatic bacteriuria in pregnancy...

Aside from the streptococci, micrococci have been the next most frequent group of organisms isolated from inflamed udders. They produce various types of disease. Some give rise to only a mild catarrh of the larger milk ducts and cystern, while others produce more or less severe parenchymatous inflammation. On the whole, the prognosis is more favorable with micrococcic infection than with that associated with streptococci. Cases of considerable severity have, however, been attributed to staphylococci. Micrococci similar in many respects to those associated with mastitis have been found to occur in the normal udder...

The objectives were, first, to determine the sensitivity and specificity of the Osmetech Microbial Analyser (OMA) for the diagnosis of bacterial vaginosis (BV) and, secondly, to determine the factors that interfere with the performance of the test. Women presenting to a genitourinary medicine clinic underwent routine screening for genital infections. Additional swabs were tested on the OMA, and by Nugent scoring. The optimum method for sampling was determined on the first 372 samples. BV was diagnosed in 182 (27%) of the remaining 665 subjects by Amsel criteria, and 188 (29%) of 642 women with evaluable Gram-stains...

The objective of this double-blind, multicenter study was to compare the efficacy and safety of oral fleroxacin, 400 mg once daily for 7 days, with amoxicillin, 500 mg administered every 8 hours for 7 days, in the treatment of acute exacerbation of chronic bronchitis. Adult male or female inpatients or outpatients were included. Patients gave informed consent and underwent a physical examination. Appropriate sputum specimens were collected, gramstained, and cultured before and 3-9 days after therapy. Complete blood count, serum chemistry, and urinalysis were performed before and 3-9 days after therapy...

The clinical significance of clostridia is much greater than is generally recognized. The organisms are a major cause of septic abortion, Clostridium perfringens being the most important single organism. This species is also the principle agent in food-poisoning. Clostridium botulinum is considered to be one of the main causes of the sudden death syndrome in infants. As clostridia are universally distributed in nature and the human body, the isolation of an organism of this group from the human body is significant only if it can be linked with pathological changes...

The quality of the morphological-biochemical identification of P. aeruginosa affects the results of group determination with anti-O-sera (Institute Pasteur Production) to a great extent. Out of 563 isolates classified as P. aeruginosa on the basis of colony morphology, haemolysis, pigment formation, odor, gramstaining and oxidase test, 84,2% react with one monovalent antiserum. Out of 498 strains which are more exactly identified by additional use of the Oxi/Ferm tube-system (Hoffmann-La Roche), 94,0% are clearly to be grouped...

A case of anaerobic sepsis associated with Fusobacterium mortiferum is reported. Blood cultures from a 60-year-old man with type II diabetes mellitus, hypertension, severe atherosclerotic cardiovascular disease, and renal insufficiency revealed on a gramstained smear highly pleomorphic gram-negative bacilli with bizarre forms and round bodies. Growth of the organism on nonselective anaerobic media and analysis of its pattern produced results characteristic of Fusobacterium mortiferum.

Seventy patients with a clinical diagnosis of Malassezia folliculitis were studied, of which 48 were confirmed on finding unipolar budding yeastlike organisms on gramstained microscopy or histology specimens. The epidemiologic and clinical features of these 48 cases (M = 44; F = 4) were analyzed. The typical Singaporean patient with Malassezia folliculitis is a young man of mean age 22.2 years with erythematous follicular papules or pustules on the upper back, shoulders, upper chest, and sides of the back. Aggravating factors include heat and sweating...

Antimicrobiologic chemotherapy is a cornerstone in the modern concept of treatment of sepsis. It is supported by a number of measures of intensive care. Externally acquired infections followed by sepsis mainly affect immunocompromised patients. They represent the minority. On the other hand, nosocomial infections play a dominant role in intensive care units. Nosocomial pneumonias and infections caused by intravascular plastics or endoprotheses are the most important reasons of sepsis. Initial antimicrobiologic therapy considers both the infectious focus and the specific epidemiology and resistance of microorganisms present in the department: it comprises the drawing of 2 to 3 blood cultures, taking of urinary cultures, tracheal secretion, liquor and wound-swaps for microbiologic examination...
