Legionella are poorly visualized with Gram stain. 3. Legionella. demo spirochetes or causitive organisms of legionella. People that interact with animals (farmers, ranchers, vets) 16 Although Legionella pneumophila is the most common disease- Legionella does not grow on common culture media because it requires certain supplementation (cysteine and iron). Legionella disease is a systemic infection with rare cardiac manifestations. stain, special stains use both science and art to provide valuable and cost-effective Dieterle Borrelia burgdorferi, Legionella pneumophila, Treponema pallidum Giemsa Helicobacter pylori, Plasmodium vivax, Rickettsia prowazekii, Rickettsia rickettsii, Rickettsia tsutsugamushi Dieterle's stain for Legionella was negative. Legionella pneumophila is a gram-negative rod, coccobacillus in tissue and clinical material, filamentous on artificial media. What is the gram stain for Legionella pneumophila? The habitat for Legionella is aquatic systems including human-constructed reservoirs, such as cooling towers and hot water tanks. Morphology of Legionella pneumophila: Legionellae are thin, non-capsulated bacilli, 25 m x 0.3-1 m, coccobacillary in clinical material and assuming longer forms in culture. Most are motile with polar or subpolar flagella. They are gram-negative but stain poorly, particularly in smears from clinical specimens. Legionella, and in the United States, up to 20% of cases are reported to be associated with travel.11 Contaminated cooling towers and water Dieterle's silver impregnation stain of a lung section showing pleomorphic bacilli of L. pneumophila Photo courtesy Dorothy I Slater Table 1.

Genus Legionella is a pathogenic group Family legionellaceae- 50 species More than 70 serogroups Species L. pneumophila:- 80-90% human infections. Legionella is a genus of pathogenic Gram-negative bacteria that includes the species L. pneumophila, causing legionellosis (all illnesses caused by Legionella) including a pneumonia-type illness called Legionnaires' disease and a mild flu-like illness called Pontiac fever.. Legionella may be visualized with a silver stain or cultured in cysteine-containing media such as buffered What stains are used for Legionella?

Final diagnosis requires isolation of the organism or immunofluorescent studies of the tissue, sera or both. Fungi and yeast are impregnated with silver and appear black against a green counterstain in the GMS stain. May weakly stain acid-fast, but loses this characteristic when grown in culture. Legionella is a ubiquitous pathogen yet the global occurrence of legionellosis is poorly understood. Microscopy: Legionellae stain poorly with gram stain.

Dieterle silver stain, 2. Specimen: Respiratory secretions (sputum, bronchial aspirate or washings), as well as pleural fluid, lung biopsy or autopsy material. Legionellae in clinical specimens stain poorly with Gram stain and the small, intracellular bacteria are rarely recognized. Silver stains such as Warthin-Starry or Dieterle stains are preferred. They usually do not stain with Gram stain, and in tissue specimens, Dieterle or Warthin-Starry stain is used to visualize these organisms. TECHNIQUE: Cut paraffin sections 4-5m. Transmission occurs primarily through inhalation Pleural fluid was Polar, subpolar, and lateral flagella may be present and most Of note, L. micdadei may be acid-fast stain positive. Silver stains such as Dieterle, Steiner, and Warthin-Starry stains aid in the detection of the organisms on tissue sections. However, these tests are difficult to read and interpret, and few (eg, Pneumocystis and Legionella direct fluorescent antibody tests) are commercially available and commonly used. pneumophila sg 4.

The Dieterle and Warthin-Starry silver impregnation techniques for spirochetes, Bartonella, and Legionella occasionally are ordered . Legionella pneumophila infection should be included in the differential diagnosis of conditions associated with reversible lesions of the corpus callosum. Upon notification of the physician by the laboratory that L. pneumophila was recovered, the patient was directed to return to the clinic for further evaluation. Examples of its uses include, lyme disease, and syphilis. described, such as the silver impregnation method of Dieterle (Dieterle, 1927); the most effective methods include antibody-coupled fluorescent dyes and immunoperoxidase staining. It is a ubiquitous aerobic gram-negative organism that lives in soil and water. In clinical specimens, the or-ganism stains poorly or not at all by Gram stain or the usual histologic stains; however, it can be demonstrated by certain silver impregnation methods Wright stain and Giemsa stain. An intracellular pathogen, effective drugs in animal models include fluoroquinolones, macrolides, TMP/SMX, rifampin and doxycycline. Recently, it has been shown that the possible aetiological agent is a microorganism which stains with some silver stains. Legionella What bacterium is diagnosed using the Dieterle silver stain? Dieterle stain. The stain was negative. Atypical bacteria like Legionella spp, 86 because of their intracellular nature, are best demonstrated using the Dieterle silver stain.
