Leishmania

Leishmania & Trypanosoma The genera Leishmania and Trypanosoma are members of the family Trypanosomatidae. These protozoans cause diseases with widely varied clinical presentations as well as geographic distributions, including leishmaniasis, American trypanosomiasis (Chagas’ disease), and African trypanosomiasis (sleeping sickness). For example, the endemic zones for African and American trypanosomiasis do not overlap, the diseases are transmitted by different vectors, they involve distinct mechanisms of pathogenesis, and they follow different clinical courses. Nonetheless, the causative agents share important biological features. Each is a hemoflagellate with a kinetoplast containing its own chromosomal DNA with highly conserved and repeated elements, each forms a single flagellum at some point during its life cycle, and each …

Chromomycosis

Essentials of Diagnosis Patients are usually immunocompetent. Found worldwide but usually in tropical or subtropical areas. Mold in culture; forms sclerotic body or muriform cell in tissue. Infection results from direct inoculation from contaminated soil or vegetative substances. Chronic indolent cutaneous verrucous lesions, most often on the feet. General Considerations Chromomycosis, also known as chromoblastomycosis, is a chronic subcutaneous infection caused by several different fungi. Although rarely seen in the United States, it is common worldwide. A. Epidemiology. Chromomycosis occurs worldwide but is most frequently encountered in tropical and subtropical regions. The most common occurrence is in barefoot individuals, particularly among agricultural workers. The organisms causing chromomycosis are found commonly in …

Sporothrix Schenckii

Essentials of Diagnosis Cigar-shaped yeast. Dimorphic: mycelial in nature, yeast in tissue. Associated with activities that involve contact with soil, sphagnum moss, decaying wood, or vegetation. Gardeners, forestry workers, miners, animal health care providers most at risk. Raised skin lesions with proximal spread along lymphatic channels. Recovery of microorganism from culture. General Considerations A. Epidemiology. Sporothrix schenckii, the causative agent of sporotrichosis, is a ubiquitous fungus commonly found in the soil, on sphagnum moss, on decaying wood, and on a variety of other vegetation. It is found worldwide but prefers a temperate or tropical climate with high humidity. Most cases of sporotrichosis are sporadic, but large human epidemics have been reported. …

Other Mycobacteria

Essentials of Diagnosis Demonstration of the acid-fast bacillus. Infections more common in immunocompromised hosts. Infections mainly pulmonary or soft tissue. General Considerations The increasingly relative importance of the atypical mycobacteria, many of which are ubiquitous in the environment, was recognized with the decline in tuberculous disease. Generally, atypical mycobacteria are unusual causes of disease in patients who are immunocompetent but can in immunocompromised hosts such as AIDS and cancer patients. Most infections caused by atypical mycobacteria are skin and soft tissue abscesses, sometimes following pulmonary infection or implantation of prosthetic devices. There have been a few reports of epidemics of iatrogenic infection with atypical mycobacteria, associated with injection of contaminated materials. …

Tularemia

Essentials of Diagnosis • Suspected in patients with fever, lymphadenopathy, and skin lesions who have a history of animal exposure (including to wild animals, ticks, or deerflies) or are coming from a high prevalence area or in laboratory personnel who work with Francisella spp. • Blood culture or other biologic specimen cultures on appropriate culture media. • Serum antibody titer = 1:160 or a fourfold increase or decrease in titer. General Considerations Francisella tularensis is the causative agent of tularemia (also called rabbit fever or deerfly fever), an infectious disease that occurs primarily in animals. It may occasionally cause human disease, which most often manifests itself by one or more skin …

Use and Administration of Itraconazole 100 mg (Sporanox)

Therapeutic use of Itraconazole 100 mg Capsules (Sporanox) Itraconazole can be used to treat various superficial fungal infections, including the dermatophytoses, pityriasis versicolor, and mucosal and cutaneous forms of candidosis. It is also effective in patients with subcutaneous infections, such as chromoblastomycosis, sporotrichosis and certain forms of phaeohyphomycosis. It has become the drug of choice for non-life-threatening forms of blastomycosis and histoplasmosis, and is a useful alternative to amphotericin B for invasive aspergillosis. Maintenance treatment with itraconazole has helped to prevent relapse in patients with AIDS with histoplasmosis or cryptococcosis, and prophylactic treatment with this drug has helped to prevent aspergillosis and candidosis in neutropenic patients. However, it has not been …

Buy Without Prescription Sporanox (Itraconazole) 100mg

Itraconazole: Side Effects See also Antifungal azoles Itraconazole is a triazole antifungal drug. It is used orally to treat oropharyngeal and vulvovaginal candidiasis, pityriasis versicolor, dermatophytoses unresponsive to topical treatment, and systemic infections, including aspergillosis, blastomycosis, chromoblastomycosis, cocci-dioidomycosis, cryptococcosis, histoplasmosis, paracocci-dioidomycosis, and sporotrichosis. It is also used to prevent fungal infections in immunocompromised patients. Pharmacokinetics The systemic availability of itraconazole and the bioequi-valence of single 200 mg doses of itraconazole solution and two capsule formulations have been evaluated in a crossover study in 30 male volunteers. Itraconazole and hydroxyitraconazole were 30-37% more available from the solution and were greater than from either capsule formulation. However, the values of Cmax, fmax, and …

Order Generic Lamisil (Terbinafine) No Prescription 250mg

Terbinafine: Side Effects The allylamine derivative terbinafine can be used orally or topically. It is active against a broad range of fungi, including filamentous fungi and, to a lesser extent, yeastlike fungi. However, probably because of irreversible protein binding, its clinical usefulness is limited to the treatment of dermatophyte infections and perhaps lymphocutaneous sporotrichosis. Terbinafine acts by inhibiting the synthesis of fungal ergosterol at the level of squalene oxidase, leading to depletion of ergosterol and accumulation of toxic squalenes in the fungal cell membrane. Pharmacokinetics Numerous reviews and studies of the pharmacokinetics of terbinafine have appeared. Independent of food, its oral availability is 70-80%. With a single dose of 250 mg, …
