Rapid diagnosis of pulmonary coccidioidomycosis. Cytologic v potassium hydroxide preparations.

Only registered users can translate articles

In 26 patients with culture-proved pulmonary coccidioidomycosis, cytologic preparations of respiratory secretions were significantly more sensitive (38.5%) than potassium hydroxide (KOH) preparations (15.4%) in identifying spherules of Coccidioides immitis. Those patients able to produce sputum or

Coccidioidomycosis in Brazil. A case report.

Only registered users can translate articles

Coccidioidomycosis is an endemic infection with a relatively limited geographic distribution: Mexico, Guatemala, Honduras, Colombia, Venezuela, Bolivia, Paraguay, Argentina and the southwest of the United States. In these countries, the endemic area is restricted to the semiarid desert like regions

Chapter 2: coccidioidomycosis.

Only registered users can translate articles

Coccidioidomycosis is a systemic mycosis caused by the dimorphic fungi Coccidioides immitis and Coccidioides posadasii. Infection is acquired by inhalation of infective arthroconidia that live in the soil. In 60% of cases, the infection is benign and resolves spontaneously. In the northern

Rapid diagnostic evaluation of bronchial washings in patients with suspected coccidioidomycosis.

Only registered users can translate articles

Coccidioidomycosis is a regionally common fungal infection, primarily affecting the lung. While in the majority of cases the tempo of the disease allows for a more leisurely diagnostic plan, including multiple serologic tests and culture of respiratory secretions, occasionally, patients will present

Concentration of Rift Valley fever and Chikungunya viruses by precipitation.

Only registered users can translate articles

Simple and efficient methods for concentrating Rift Valley fever (RVF) virus and chikungunya (CHIK) virus are described. Ammonium sulfate, potassium sulfate, or alcohol was used as a precipitating agent and the precipitate was resuspended to volumes suitable for further processing and purification.

Experimental infection of three indigenous breeds of sheep in Nigeria, namely the West African Dwarf (WAD), Yankasa and Ouda resulted in fatal disease with the Zinga Rift Valley Fever virus. Infected sheep of the three breeds responded by pyrexia within 24 h of infection, that lasted 6 to 7 days,

Rift Valley fever virus structural proteins: expression, characterization and assembly of recombinant proteins.

Only registered users can translate articles

BACKGROUND Studies on Rift Valley Fever Virus (RVFV) infection process and morphogenesis have been hampered due to the biosafety conditions required to handle this virus, making alternative systems such as recombinant virus-like particles, that may facilitate understanding of these processes are

Primary cutaneous coccidioidomycosis: a review of the literature and a report of a new case.

Only registered users can translate articles

A 31-year-old woman working in the laboratory with the mycelial phase of Coccidioides immitis developed a firm, raised, erythematous lesion on the left index finger. A biopsy specimen of the lesion grew a white mold that proved to be C immitis. A sinus tract communicating with the lesion and

Chemotherapy for the systemic mycoses: the prelude to ketoconazole.

Only registered users can translate articles

Successful chemotherapy of the systemic mycoses now covers a span of more than 75 years and dates to the first reported use of potassium iodide for treatment of sporotrichosis. The second drug with efficacy was stilbamidine, and its currently available successor, hydroxystilbamidine isethionate,

Parasitic polymorphism of Coccidioides spp.

Only registered users can translate articles

BACKGROUND Coccidioides spp. is the ethiological agent of coccidioidomycosis, an infection that can be fatal. Its diagnosis is complicated, due to that it shares clinical and histopathological characteristics with other pulmonary mycoses. Coccidioides spp. is a dimorphic fungus and, in its saprobic

Drugs for fungal infections.

Only registered users can translate articles

The type of fungal infection and the immunologic status of the patient determine whether drug therapy should be used. Amphotericin B is the single most important antifungal agent for the treatment of systemic mycoses. Flucytosine is given adjunctively with amphotericin B. Miconazole, a new

Erythema nodosum. A review.

Only registered users can translate articles

Erythema nodosum is not an uncommon dermatologic entity. Sarcoidosis and streptococcal infection have become the two most common causes, while tuberculosis was the predominant etiology prior to the use of isoniazid. Histoplasmosis and coccidioidomycosis are two important geographic considerations.

Coccidioidal peritonitis associated with continuous ambulatory peritoneal dialysis.

Only registered users can translate articles

We report the first three cases of peritonitis due to the fungus Coccidioides immitis occurring during continuous ambulatory peritoneal dialysis (CAPD). At the time of diagnosis, none of the patients had evidence of active infection outside of the peritoneal cavity. Clues suggesting the diagnosis

Novel ionophores active against La Crosse virus identified through rapid antiviral screening.

Only registered users can translate articles

Bunyaviruses are significant human pathogens, causing diseases ranging from hemorrhagic fevers to encephalitis. Among these viruses, La Crosse virus (LACV), a member of the California serogroup, circulates in the eastern and midwestern United States. While LACV infection is often asymptomatic,

Amphotericin B: spectrum and resistance.

Only registered users can translate articles

Amphotericin B is a polyene macrolide antibiotic derived from the actinomycete Streptomyces nodosus. Of the 200 known polyene agents, amphotericin B is the only one with toxicities that are sufficiently limited to permit intravenous administration. All polyenes have a common mechanism of action in
