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 …

Fusarium, Penicillium, Paracoccidioides, & Agents of Chromomycosis

FUSARIUM INFECTION Essentials of Diagnosis Worldwide geographic distribution. Mold, septate hyphae 3-8 um in diameter. A rare infection in severely immunocompromised patients. Blood cultures often but not always positive. No serologic tests available. Cutaneous involvement is common feature. General Considerations A. Epidemiology. Fusarium spp. is an emerging fungal pathogen. Although long recognized as a cause of local infection involving nails, traumatized skin, or the cornea (eg, in contact lens wearers), deep or disseminated infection was not described until the mid 1970s. Despite its worldwide distribution and its frequent recovery from soil and vegetative material, infection is quite rare. Only ~ 100 cases involving invasive disease in immunosuppressed patients have been described …

Paracoccidioidomycosis

Essentials of Diagnosis Patients usually immunocompetent. Patients in endemic areas with chronic pulmonary and mucotaneous lesions involving the mouth, nose, larynx, and face; regional or diffuse lymphadenopathy. Found in Latin America, from Mexico to Argentina. Dimorphic fungus: yeast form in tissue specimens and at 37 °C; mold form when grown at room temperature in the laboratory. Thick-walled yeast, 4-40 um, with multiple buds when seen in tissue specimens. Complement fixation or immunodiffusion. General Considerations Paracoccidioidomycosis is caused by Paracoccidioides brasiliensis. Also known as South American blastomycosis, it is the most prevalent systemic mycosis found in Central and South America and is the most common endemic mycosis in this area. A. Epidemiology. …

Coccidioides

Essentials of Diagnosis Predisposing factors include travel to the dry desert climates found in the southwestern United States and exposure to dust. The commonest source of infection is dust inhalation in the southwestern United States. The commonest infection is pneumonia. Key laboratory findings include growth of the fungus and complement fixing (CF) antigen detection by immunodiffusion. General Considerations Coccidioidomycosis was first described as a disease a little more than a century ago in Buenos Aires, Argentina. It was in San Francisco that the organism causing the clinical disease was given its name, Coccidioides immitis. Many diseases were later found to be caused by this organism, including San Joaquin Valley Fever. A. …

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 …

HIV / AIDS

Definition Table Centers for Disease Control and Prevention 1993 Revised Classification System for HIV Infection in Adults and AIDS Surveillance Case Definition and Table Centers for Disease Control and Prevention 1994 Revised Classification System for HIV Infection in Children Younger than 13 Years present the revised classification systems for adult and child HIV infection. Pathogenesis Transmission of HIV Infection with HIV occurs through three primary modes: sexual, parenteral, and perinatal. Sexual intercourse, primarily receptive anal and vaginal intercourse, is the most common vehicle for transmission. The probability of HIV transmission from receptive anorectal intercourse is 0.1% to 3% per sexual contact and 0.1% to 0.2% per sexual contact for receptive vaginal …
