A fungal infection that may appear in two forms: 1, a primary lesion characterized by the formation of a small cutaneous nodule and small nodules along the lymphatics that may heal within several months; and 2, chronic granulomatous lesions characterized by thick crusts, warty growths, and unusual vascularity and infection in the middle or upper lobes of the lung.
Infection with a fungus of the genus COCCIDIOIDES, endemic to the SOUTHWESTERN UNITED STATES. It is sometimes called valley fever but should not be confused with RIFT VALLEY FEVER. Infection is caused by inhalation of airborne, fungal particles known as arthroconidia, a form of FUNGAL SPORES. A primary form is an acute, benign, self-limited respiratory infection. A secondary form is a virulent, severe, chronic, progressive granulomatous disease with systemic involvement. It can be detected by use of COCCIDIOIDIN.
Meningeal inflammation produced by CRYPTOCOCCUS NEOFORMANS, an encapsulated yeast that tends to infect individuals with ACQUIRED IMMUNODEFICIENCY SYNDROME and other immunocompromised states. The organism enters the body through the respiratory tract, but symptomatic infections are usually limited to the lungs and nervous system. The organism may also produce parenchymal brain lesions (torulomas). Clinically, the course is subacute and may feature HEADACHE; NAUSEA; PHOTOPHOBIA; focal neurologic deficits; SEIZURES; cranial neuropathies; and HYDROCEPHALUS. (From Adams et al., Principles of Neurology, 6th ed, pp721-2)

A genus of mitosporic fungi containing about 100 species and eleven different teleomorphs in the family Trichocomaceae.
Infections of the respiratory tract with fungi of the genus ASPERGILLUS.

A fungal toxin produced by various species of Trichoderma, Gladiocladium fimbriatum, Aspergillus fumigatus, and Penicillium. It is used as an immunosuppressive agent.
Infections of the central nervous system caused by TREPONEMA PALLIDUM which present with a variety of clinical syndromes. The initial phase of infection usually causes a mild or asymptomatic meningeal reaction. The meningovascular form may present acutely as BRAIN INFARCTION. The infection may also remain subclinical for several years. Late syndromes include general paresis; TABES DORSALIS; meningeal syphilis; syphilitic OPTIC ATROPHY; and spinal syphilis. General paresis is characterized by progressive DEMENTIA; DYSARTHRIA; TREMOR; MYOCLONUS; SEIZURES; and Argyll-Robertson pupils. (Adams et al., Principles of Neurology, 6th ed, pp722-8)
A form of bacterial meningitis caused by MYCOBACTERIUM TUBERCULOSIS or rarely MYCOBACTERIUM BOVIS. The organism seeds the meninges and forms microtuberculomas which subsequently rupture.

Headache and meningeal irritation may be followed by SEIZURES, cranial neuropathies, focal neurologic deficits, somnolence, and eventually COMA. The illness may occur in immunocompetent individuals or as an OPPORTUNISTIC INFECTION in the ACQUIRED IMMUNODEFICIENCY SYNDROME and other immunodeficiency syndromes.

Inflammation of the coverings of the brain and/or spinal cord, which consist of the PIA MATER; ARACHNOID; and DURA MATER. Infections (viral, bacterial, and fungal) are the most common causes of this condition, but subarachnoid hemorrhage (HEMORRHAGES, SUBARACHNOID), chemical irritation (chemical MENINGITIS), granulomatous conditions, neoplastic conditions (CARCINOMATOUS MENINGITIS), and other inflammatory conditions may produce this syndrome.

  • Collectively, treatment with ketoconazole resulted in a prominent inhibitory effect on the metabolism of BOS, followed by treatment with fluconazole, voriconazole, and itraconazole. (

  • Fungal Infections (Yeast Infections, Vaginal Candidiasis , Vaginitis) Candidiasis is a very common vaginal infection caused by yeast (fungus). (
  • Little is known about fungal biofilms, which may cause infection and antibiotic resistance. (
  • Because immunosuppression predisposes to infection by C. neoformans and both CsA and FK506 exacerbate C. neoformans meningitis ( 39 , 41 ), these potent immunosuppressive agents cannot be used alone to treat fungal meningitis. (
  • However, these decreases have not been observed among HIV-infected injecting-drug users, suggesting that more emphasis should be placed on providing currently recommended chemoprophylactic agents to all persons who have HIV infection and who meet appropriate criteria for prophylaxis for opportunistic infections. (

  • A 25 to 60% mortality rate associated with disseminated infection has been reported ( 11 ), due in part to the limited number of antifungal agents available and in part to increasing resistance to the most popularly used drug, fluconazole. (
  • Preventing a yeast infection with Fluconazole ( brand name Diflucan ) is not in any way preventing a yeast infection. (
  • Drug companies will have you purchasing their drugs for years and tell you that if you stay on Fluconazole for years that you are preventing a yeast infection. (
  • The bacterial balance in your body has been disrupted, and that is why you now have to think of doing things like taking Fluconazole to prevent your next yeast infection. (
  • If you want to prevent a fungal infection then you have to get your bacterial balance back. (
  • If you've been using anti fungal drugs, and your infection keeps coming back then the fungus in your body is slowly getting drug resistant. (
  • In addition, during systemic infections, one way the host defends itself is by regulating metal levels in tissues surrounding the fungal infection. (
  • Yeast infection treatments, which fail to respond to conventional anti-fungal drug treatments, have become increasingly reported, just like antibiotic resistant bacterial infections have over the years. (
  • You medical doctor may well prescribe an antifungal drug if he or she suspects a fungal infection, and a drug of this nature will only be prescribed if a fungal infection is diagnosed after a swab is returned positive. (
  • If it is severe, or there is associated fever, it may be secondarily infected with viral or fungal infection and swabs should be taken. (
  • Cryptococcus neoformans is an opportunistic fungal pathogen that causes life-threatening infections of the central nervous system. (

  • 3 - Fluconazole (Diflucan) is taken at 200 mg the first day, then 100 mg once a day thereafter. (
  • Studies suggest that fluconazole is more effective than ketoconazole, and I can vouch for the effectiveness of Diflucan in the clinic, it certainly works for many, but is not always successful because like most drugs the causes are never really addressed adequately by the doctor. (
  • In addition, I highly recommend that you naturopath prescribe you a liver supplement for three weeks to clear any Diflucan drug residues from your liver. (

  • William Hope , Professor of Therapeutics and Infectious Diseases at the University of Liverpool, said: "This study is unique in that it combines information from experimental models of cryptococcal meningitis with data from patients receiving fluconazole as monotherapy, which remains the norm in much of Africa, despite not being consistent with current treatment recommendations from the WHO. (
