A mitosporic fungal genus which causes COCCIDIOIDOMYCOSIS.
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.
Suspensions of attenuated or killed fungi administered for the prevention or treatment of infectious fungal disease.
A sterile solution containing the by-products of growth products of COCCIDIOIDES IMMITIS, injected intracutaneously as a test for COCCIDIOIDOMYCOSIS.
Substances of fungal origin that have antigenic activity.
Immunoglobulins produced in a response to FUNGAL ANTIGENS.
Meningitis caused by fungal agents which may occur as OPPORTUNISTIC INFECTIONS or arise in immunocompetent hosts.
A genus of onygenacetous mitosporic fungi whose perfect state is Ajellomyces (see ONYGENALES). The species Blastomyces dermatitidis (perfect state Ajellomyces dermatitidis) causes blastomycosis.
A mitosporic Onygenales fungal genus causing HISTOPLASMOSIS in humans and animals. Its single species is Histoplasma capsulatum which has two varieties: H. capsulatum var. capsulatum and H. capsulatum var. duboisii. Its teleomorph is AJELLOMYCES capsulatus.
An order of fungi in the phylum ASCOMYCOTA containing many medically important species. There are four families and mitosporic (anamorphic) forms are prominent.
Pulmonary diseases caused by fungal infections, usually through hematogenous spread.
Technique involving the diffusion of antigen or antibody through a semisolid medium, usually agar or agarose gel, with the result being a precipitin reaction.
Serologic tests based on inactivation of complement by the antigen-antibody complex (stage 1). Binding of free complement can be visualized by addition of a second antigen-antibody system such as red cells and appropriate red cell antibody (hemolysin) requiring complement for its completion (stage 2). Failure of the red cells to lyse indicates that a specific antigen-antibody reaction has taken place in stage 1. If red cells lyse, free complement is present indicating no antigen-antibody reaction occurred in stage 1.
Infection resulting from inhalation or ingestion of spores of the fungus of the genus HISTOPLASMA, species H. capsulatum. It is worldwide in distribution and particularly common in the midwestern United States. (From Dorland, 27th ed)

Lung weight parallels disease severity in experimental coccidioidomycosis. (1/344)

Evidence provided by histopathological study of lesions is a valuable adjunct for evaluating chemotherapeutic efficacy in experimental animal models, In addition, this should be correlated with a measure of disease severity in the same animal. The latter could be obtained by homogenization of infected organs and quantitative enumeration of viable cells of the etiological agent, but this would preclude histopathological studies in the same animal. Progression of disease in pulmonary infection is associated with replacement of air space by fluid, cells, and cellular debris. Therefore, an increase in lung weight should reflect severity of disease. Results with the murine model of coccidioidomycosis demonstrate that increasing lung weight parallels the increasing census of fungus cells in the lungs of both treated and nontreated infected mice. This was supported with evidence obtained from microscopic studies of lesions indicating that specific chemotherapy limited spread of the infection and inhibited multiplication of the fungus in the lung. Therefore, lung weight can be used as a measure of disease severity in the murine model of coccidioidomycosis.  (+info)

Reactivation of coccidioidomycosis in a fit American visitor. (2/344)

The case history is presented of an American visitor, known to have had primary coccidioidomycosis previously, who became very unwell during a visit to the UK. Despite consideration of reactivation of coccidioidomycosis from the outset, other pathogens were identified while Coccidioides immitis was not initially, leading to a delay in treatment.  (+info)

The first imported case of pulmonary coccidioidomycosis in Korea. (3/344)

Coccidioidomycosis is an endemic disease found in the southwestern part of North America. Travellers who visit the endemic area may carry the infection. We report a case of pulmonary coccidioidomycosis in a 74-year-old woman. She was healthy before visiting Arizona, U.S.A twice. After returning home, she began to complain of intermittent dry coughing. The symptom was mild, however, and she was treated symptomatically. Later a chest radiograph, which was taken 4 years after the onset of the symptom, showed a solitary pulmonary nodule in the right upper lobe. By percutaneous needle aspiration, a few clusters of atypical cells were noted in the necrotic background. A right upper and middle lobectomy was done. A 1.5 x 1.5 x 1.2 cm sized tan nodule was present in otherwise normal lung parenchyma. Microscopically, the nodule consisted of aggregates of multiple solid granulomas inside of which was mostly necrotic. Neutrophils and nuclear debris were scattered along the periphery of the necrotic foci. Numerous multinucleated giant cells were associated with the granulomas. In the necrotic area, mature spherules of Coccidioides immitis, which were 30-100 microm in diameter, were present. They contained numerous endospores which ranged from 5 to 15 microm and were also noted in multinucleated giant cells. The diagnosis of coccidioidomycosis was made. She is doing well after the resection.  (+info)

Genes influencing resistance to Coccidioides immitis and the interleukin-10 response map to chromosomes 4 and 6 in mice. (4/344)

Coccidioidomycosis is a fungal infection that is endemic in the southwestern United States. Infection is more severe in blacks and Filipinos, which suggests that there is a genetic basis for susceptibility to this infection in humans. We found that there is also a difference in resistance to Coccidioides immitis infection among inbred mouse strains: B6 mice are susceptible, while DBA/2 mice are resistant (T. N. Kirkland and J. Fierer, Infect. Immun. 40:912-916, 1983). In this paper we report the results of our efforts to map the genes responsible for resistance to this infection in mice. Mice were infected by intraperitoneal inoculation, and 15 days later the numbers of viable fungi in their lungs and spleens were enumerated. We also determined the amounts of interleukin-10 mRNA made in the infected lungs. These three phenotypes were mapped as quantitative traits by using the 26 available lines of recombinant inbred mice derived from a cross between B6 and DBA/2 mice. The best associations were those between the regions near the Lv locus on chromosome 4 and the Tnfr1 locus on chromosome 6. We then infected backcross mice [(B6 x DBA/2) x B6] and confirmed these associations; 14 of 16 (87%) mice that were heterozygous at both Lv and Tnfr1 were resistant to infection, whereas only 4 of 16 (25%) mice that were homozygous B6 at both loci were resistant. These are the first genetic loci to be associated with susceptibility to C. immitis, but there may be additional genes involved in murine resistance to this infection.  (+info)

Resistance to Coccidioides immitis in mice after immunization with recombinant protein or a DNA vaccine of a proline-rich antigen. (5/344)

Two inbred strains of mice (BALB/c and C57BL/6) were vaccinated with either recombinant expression protein of a Coccidioides immitis spherule-derived proline-rich antigen (rPRA) in monophosphoryl lipid A-oil emulsion adjuvant or a DNA vaccine based on the same antigen. Four weeks after vaccination, mice were infected intraperitoneally with arthroconidia. By 2 weeks, groups of mice receiving saline or plasmids with no PRA insert exhibited significant weight loss, and quantitative CFUs in the lungs ranged from 5.9 to 6.4 log10. In contrast, groups of mice immunized with either rPRA or DNA vaccine had significantly smaller pulmonary fungal burdens, ranging from 3.0 to 4.5 log10 fewer CFUs. In vitro immunologic markers of lymphocyte proliferation and gamma interferon (IFN-gamma) release after splenocytes were stimulated with rPRA correlated with protection. Also, plasma concentrations of rPRA-specific total immunoglobulin G (IgG), IgG1, and IgG2a showed increases in vaccinated mice. These studies expand earlier work by demonstrating protection in mice which differ in H-2 background, by using an adjuvant that is potentially applicable to human use, and by achieving comparable protections with a DNA-based vaccine. Our in vitro results substantiate a Th1 response as evidenced by IFN-gamma release and increased IgG2a. However, IgG1 was also stimulated, suggesting some Th2 response as well. PRA is a promising vaccine candidate for prevention of coccidioidomycosis and warrants further investigation.  (+info)

Coadministration of interleukin 12 expression vector with antigen 2 cDNA enhances induction of protective immunity against Coccidioides immitis. (6/344)

Interleukin 12 (IL-12) plays an important role in the induction of protective immunity against cancer and infectious diseases. In this study we asked whether IL-12 cDNA could increase the protective capacity of the antigen 2 (Ag2) gene vaccine in experimental coccidioidomycosis. Coimmunization of BALB/c mice with a single-chain IL-12 cDNA (p40-L-p35) and Ag2 cDNA, both subcloned into the pVR1012 plasmid, significantly enhanced protection against systemic challenge with 2,500 arthroconidia, as evidenced by a greater-than-1.3-log-unit reduction in the fungal load in the lungs and spleens compared to mice receiving the pVR1012 vector alone, Ag2 cDNA alone, or IL-12 cDNA alone. The enhanced protection was associated with increased gamma interferon secretion; production of immunoglobulin G2a (IgG2a), IgG2b, and IgG3 antibodies to Coccidioides immitis antigen; and the influx of CD4(+) and CD8(+) T cells in lungs and spleens. When challenged by the pulmonary route, mice covaccinated with Ag2 cDNA and IL-12 cDNA were not protected at the lung level but did show a significant reduction in the fungal load in their livers and spleens compared to mice vaccinated with Ag2 cDNA or IL-12 cDNA alone. These results suggest that IL-12 acts as a therapeutic adjuvant to enhance Ag2 cDNA-induced protective immunity against experimental coccidioidomycosis through the induction of Th1-associated immune responses.  (+info)

Outbreak of coccidioidomycosis in Washington state residents returning from Mexico. (7/344)

In July 1996 the Washington State Department of Health (Seattle) was notified of a cluster of a flulike, rash-associated illness in a 126-member church group, many of whom were adolescents. The group had recently returned from Tecate, Mexico, where members had assisted with construction projects at an orphanage. After 1 member was diagnosed with coccidioidomycosis, we initiated a study to identify further cases. We identified 21 serologically confirmed cases of coccidioidomycosis (minimum attack rate, 17%). Twenty cases (95%) occurred in adolescents, and 13 patients (62%) had rash. Sixteen symptomatic patients saw 19 health care providers; 1 health care provider correctly diagnosed coccidioidomycosis. Coccidioides immitis was isolated from soil samples from Tecate by use of the intraperitoneal mouse inoculation method. Trip organizers were unaware of the potential for C. immitis infection. Travelers visiting regions where C. immitis is endemic should be made aware of the risk of acquiring coccidioidomycosis, and health care providers should be familiar with coccidioidomycosis and its diagnosis.  (+info)

A major cell surface antigen of Coccidioides immitis which elicits both humoral and cellular immune responses. (8/344)

Multinucleate parasitic cells (spherules) of Coccidioides immitis isolates produce a membranous outer wall component (SOW) in vitro which has been reported to be reactive with antibody from patients with coccidioidal infection, elicits a potent proliferative response of murine immune T cells, and has immunoprotective capacity in a murine model of coccidioidomycosis. To identify the antigenic components of SOW, the crude wall material was first subjected to Triton X-114 extraction, and a water-soluble fraction derived from this treatment was examined for protein composition and reactivity in humoral and cellular immunoassays. Protein electrophoresis revealed that the aqueous fraction of three different isolates of C. immitis each contained one or two major glycoproteins (SOWgps), distinguished by their molecular sizes, which ranged from 58 to 82 kDa. The SOWgps, however, showed identical N-terminal amino acid sequences, and each was recognized by sera from patients with C. immitis infection. Antibody raised against the purified 58-kDa glycoprotein (SOWgp58) of the Silveira isolate was used for Western blot and immunolocalization analyses. Expression of SOWgp was shown to be parasitic phase specific, and the antigen was localized to the membranous SOW. The water-soluble fraction of SOW and the purified SOWgp58 were tested for the ability to stimulate proliferation of human peripheral monocytic cells (PBMC). The latter were obtained from healthy volunteers with positive skin test reaction to spherulin, a parasitic-phase antigen of C. immitis, and from volunteers who showed no skin test reaction to the same antigen. The SOW preparations stimulated proliferation of PBMC from skin test-positive but not skin test-negative donors, and the activated cells secreted gamma interferon, which is indicative of a T helper 1 pathway of immune response. Results of this study suggest that SOWgp is a major parasitic cell surface-expressed antigen that elicits both humoral and cellular immune responses in patients with coccidioidal infection.  (+info)

While most Ascomycetes tend to associate principally with plants, the dimorphic fungi Coccidioides immitis and Coccidioides posadasii are primary pathogens of immunocompetent mammals, including humans. Infection results from environmental exposure to Coccidiodies, which is believed to grow as a soil saprophyte in arid deserts. To investigate hypotheses about the life history and evolution of Coccidioides, the genomes of several Onygenales, including C. immitis and C. posadasii; a close, nonpathogenic relative, Uncinocarpus reesii; and a more diverged pathogenic fungus, Histoplasma capsulatum, were sequenced and compared with those of 13 more distantly related Ascomycetes. This analysis identified increases and decreases in gene family size associated with a host/substrate shift from plants to animals in the Onygenales. In addition, comparison among Onygenales genomes revealed evolutionary changes in Coccidioides that may underlie its infectious phenotype, the identification of which may ...
Coccidioides is a genus of dimorphic ascomycetes in the family Onygenaceae. Member species are the cause of coccidioidomycosis, also known as San Joaquin Valley fever, an infectious fungal disease largely confined to the Western Hemisphere and endemic in the Southwestern United States. The host acquires the disease by respiratory inhalation of spores disseminated in their natural habitat. The causative agents of coccidioidomycosis are Coccidioides immitis and Coccidioides posadasii. Both C. immitis and C. posadasii are indistinguishable during laboratory testing and commonly referred in literature as Coccidioides. Coccidioidomycosis is amazingly diverse in terms of its scope of clinical presentation, as well as clinical severity. About 60% of Coccidioides infections as determined by serologic conversion are asymptomatic. The most common clinical syndrome in the other 40% of infected patients is an acute respiratory illness characterized by fever, cough, and pleuritic pain. Skin manifestations, ...

Coccidioidal infection is overcome by the development of cell-mediated immunity. This study evaluated the role of dendritic cells (DCs) in the initiation of coccidioidal immunity in nonimmune individuals. It was demonstrated that DCs pulsed with the coccidioidal antigen preparation, toluene spherule lysate (TSL), induce DC maturation, autologous lymphocyte proliferation, and antigen-specific lymphocyte responses from nonimmune donors. Furthermore, TSL-primed lymphocytes secreted interferon - γ after restimulation with TSL or antigen 2/proline-rich antigen, a subcomponent of TSL, but they did not do so when restimulated with ovalbumin or ...

For patients who are unresponsive to fluconazole, options are limited. Several case reports have studied the efficacy of three newer antifungal agents in the treatment of disease that is refractory to first-line therapy: posaconazole and voriconazole (triazole compounds similar in structure to fluconazole) and caspofungin (glucan synthesis inhibitor of the echinocandin structural class). However, these drugs have not been FDA approved, and clinical trials are lacking. Susceptibility testing of Coccidioides species in one report revealed uniform susceptibility to most antifungal agents, including these newer drugs. In very severe cases, combination therapy with amphotericin B and an azole have been postulated, although no trials have been conducted. Caspofungin in combination with fluconazole has been cited as beneficial in a case report of a 31-year-old Asian patient with coccidioidal pneumonia. In a case report of a 23-year-old Black male with HIV and coccidioidal meningitis, combination ...

Coccidioides is a fungi that is responsible for causing infections in the Southwestern part of the United States. It is a dimorphic fungi, taking on the form of a mold outside the body and a large spherule filled with endospores inside the human body. Coccidioides is endemic to the Southwestern US and is specifically associated with inhalation of spores in dust. Infections with Coccidioides causes Coccidioidomycosis, which is also known as San Joaquin Valley Fever or simply Valley Fever. Patients typically present with pneumonia, arthralgias, and skin manifestations such as erythema nodosum and erythema multiforme. Histopathology of affected tissues reveal granulomas and fungal spherules filled with endospores. While treatment for mild infections is supportive, severe infections can be treated with fluconazole or itraconazole for local symptoms and Amphotericin B for severe systemic infections.
Peritoneal macrophages from normal mice phagocytized arthroconidia and endospores of Coccidioides immitis without affecting the viability of the spores within 4 h after infection. In contrast, macrophages, when infected in the presence of lymphocytes from immune mice, significantly reduced the viability of phagocytized endospores and arthroconidia. The inability of macrophages from normal mice to kill C. immitis may in part be explained by the observation that C. immitis appeared to inhibit fusion of the phagosomes containing fungal spores with the lysosomes within the macrophages. However, fusion of phagosomes containing spores and lysosomes was observed in macrophages infected in the presence of lymphocytes from immune mice. ...
Primary coccidioidal disease is rarely diagnosed in the midwest in the nonimmunocompromised host. Since coast-to-coast travel is common today, many patients may become exposed to Coccidioides immitis while traveling in endemic areas. We present a case of acute coccidioidal pleural effusion in a Michigan woman who had recently visited northeastern Arizona. Her travel history was the single most important factor in the eventual diagnosis of coccidioidal pleural effusion.
Coccidioides species are dimorphic fungi. Coccidioides immitis is endemic to the San Joaquin valley of California; Coccidioides posadasii is found in desert regions of the southwestern United States including Arizona, Utah, New Mexico, and West Texas, and also in parts of Mexico, Argentina, Paraguay and Central America. There is very little difference in morphology or clinical presentation between the 2 species, and both can cause the disease coccidioidomycosis, also referred to as Valley Fever.. Coccidioides fungi are commonly found in soil and dust in endemic areas (Johnson et al., 2014). Arthroconidida are the infectious form of the fungi. When the arthroconidida dissociate, they can be carried by the wind for many miles. Coccidioidomycosis cases increase when there are rainy summers followed by dry winters, and after earthquakes or after humans disturb the soil by plowing, construction or similar activities.. When the anrthroconidida are inhaled into the lungs, they transform into ...

Coccidioidomycosis is a fungal infection that usually presents as a primary lung infection. The fungus is endemic to the Southwest United States of America, northern Mexico and parts of Central and South America the infection is rare outside these areas. However, some patients develop disseminated infection that can lie dormant for several years and can present itself in travelers. We report the first case of extra pulmonary Coccidioidomycosis in a non-immunocompromised individual in Denmark. A 32 year old Danish woman presented at the Emergency department with abdominal pain. Computed tomography scan and ultrasound examination of the pelvis raised suspicion of salpingitis. A laparoscopy exposed a necrotic salpinx and several small white elements that resembled peritoneal carcinomatosis. Histological workup however determined that she suffered from disseminated coccidioidomycosis. The patient had lived 2 years in Las Vegas, in the United States of America, 7 years prior and had no memory of lung

Healthcare: Antibiotic avoidance. Over a third of women presenting with urinary tract infection symptoms are happy to delay antibiotic treatment when asked by their GP, with the majority of these patients showing an improvement in symptoms without the need for further treatment. This intriguingly suggests that patients are much more open to reducing unnecessary antibiotic use than is often thought. More on this study over on our blog.. Microbiology: Conversion of Coccidioides. Coccidioides immitis is a disease-causing fungus in mammals that exists as molds in the wild, growing in the desert soils of the southwestern US, and in Central and South America. In humans it can cause Valley Fever or pneumonia through inhalation of spores which eventually turn into pathogenic spherules. Viriyakosol et al. now report that this conversion from spores to spherules requires major transcriptional reprogramming, and has little congruence with genetic mechanisms displayed in other dimorphic fungi..

Glycolysis is the process of converting glucose into pyruvate and generating small amounts of ATP (energy) and NADH (reducing power). It is a central pathway that produces important precursor metabolites: six-carbon compounds of glucose-6P and fructose-6P and three-carbon compounds of glycerone-P, glyceraldehyde-3P, glycerate-3P, phosphoenolpyruvate, and pyruvate [MD:M00001]. Acetyl-CoA, another important precursor metabolite, is produced by oxidative decarboxylation of pyruvate [MD:M00307]. When the enzyme genes of this pathway are examined in completely sequenced genomes, the reaction steps of three-carbon compounds from glycerone-P to pyruvate form a conserved core module [MD:M00002], which is found in almost all organisms and which sometimes contains operon structures in bacterial genomes. Gluconeogenesis is a synthesis pathway of glucose from noncarbohydrate precursors. It is essentially a reversal of glycolysis with minor variations of alternative paths [MD:M00003 ...
Linoleate dioxygenase-cytochrome P450 (DOX-CYP) fusion enzymes are common in pathogenic fungi. The DOX domains form hydroperoxy metabolites of 18:2n-6, which can be transformed by the CYP domains to 1,2- or 1,4-diols, epoxy alcohols, or to allene oxides. We have characterized two novel allene oxide synthases (AOSs), namely, recombinant 8R-DOX-AOS of Coccidioides immitis (causing valley fever) and 8S-DOX-AOS of Zymoseptoria tritici (causing septoria tritici blotch of wheat). The 8R-DOX-AOS oxidized 18:2n-6 sequentially to 8R-hydroperoxy-9Z,12Z-octadecadienoic acid (8R-HPODE) and to an allene oxide, 8R(9)-epoxy-9,12Z-octadecadienoic acid, as judged from the accumulation of the α-ketol, 8S-hydroxy-9-oxo-12Z-octadecenoic acid. The 8S-DOX-AOS of Z. tritici transformed 18:2n-6 sequentially to 8S-HPODE and to an α-ketol, 8R-hydroxy-9-oxo-12Z-octadecenoic acid, likely formed by hydrolysis of 8S(9)-epoxy-9,12Z-octadecadienoic acid. The 8S-DOX-AOS oxidized [8R-(2)H]18:2n-6 to 8S-HPODE with retention of ...
ribose-5-phosphate isomerage B (RpiB):Presented here is a series of crystal structures solved by the Seattle Structural Genomics Center for Infectious Disease (SSGCID) of ribose-5-phosphate isomerase B, or RpiB, from the pathogenic fungus, Coccidioides immitis. This parasite, which resides in the soil in certain parts of the western hemisphere, causes coccidioidomycosis, also known as Valley Fever. The disease is difficult to diagnose as it causes masses which mimics a lung tumor. Ribose-5-phosphate isomerase is an enzyme that catalyzes the conversion between ribose-5-phosphate and ribulose-5-phosphate. This family of enzymes naturally occurs in two distinct classes, RpiA and RpiB, which play, among others, an important role in the pentose phosphate pathway, which converts a type of glucose into other molecules. Although RpiB occurs predominantly in bacteria, the RpiB from this fungal pathogen contains high structural similarity to other known RpiB structures despite modest sequence similarity. The C.

A general rule with any fungal infection is that it takes a long time to clear. Valley Fever is no different and a year of medication administration is fairly common. Treatment continues until the clinical signs have resolved, the radiographs look normal, and the antibody level has stabilized (note antibody levels may never fully drop to zero). Ketoconazole, itraconazole , and fluconazole are the usual drugs to treat this condition. Monitoring liver enzymes is important with all of these, particularly since long treatment courses are common.. Lufenuron, the active ingredient in the flea control product Program, was developed to inhibit the development of chitin (the crunchy exterior material of the insect body). The idea was that a flea larva who had fed upon blood pellets (flea dirt) from a pet treated with oral lufenuron would be unable to properly pupate into an adult flea. It turns out that the shell of Coccidioides immitis is also rich in chitin and that lufenuron at specific doses may be ...

Once in contact with the host immune system, the microorganism faces the hosts tightly integrated cellular and humoral immune responses. Cellular immunity, comprising T lymphocytes, macrophages, and natural killer cells, primarily recognizes and combats pathogens that proliferate intracellularly. Cellular immune mechanisms are important in immunity to all classes of infectious agents, including most viruses and many bacteria (e.g., Mycoplasma, Chlamydophila, Listeria, Salmonella, and Mycobacterium), parasites (e.g., Trypanosoma, Toxoplasma, and Leishmania), and fungi (e.g., Histoplasma, Cryptococcus, and Coccidioides). Usually, T lymphocytes are activated by macrophages and B lymphocytes, which present foreign antigens along with the hosts own major histocompatibility complex antigen to the T-cell receptor. Activated T cells may then act in several ways to fight infection. Cytotoxic T cells may directly attack and lyse host cells that express foreign antigens. Helper T cells stimulate the ...

Coccidioidomycosis consists of a spectrum of disease, ranging from a mild, self-limited, febrile illness to severe, life-threatening infection. It is caused by the soil-dwelling fungi, Coccidioides immitis and C. posadasii, which are present in diverse endemic areas. Climate changes and environmental factors affect the Coccidioides lifecycle and influence infection rates. The incidence of coccidioidomycosis has risen substantially over the past two decades. The vast majority of Coccidioides infections occur in the endemic zones, such as California, Arizona, Mexico, and Central America. Infections occurring outside those zones appear to be increasingly common, and pose unique clinical and public health challenges. It has long been known that elderly persons, pregnant women, and members of certain ethnic groups are at risk for severe or disseminated coccidioidomycosis. In recent years, it has become evident that persons with immunodeficiency diseases, diabetics, transplant recipients, and ...

N2 - The proinflammatory cytokines tumor necrosis factor alpha (TNF-α), interleukin-1α (IL-1α), and interleukin-6 (IL-6) were induced in mice infected with Coccidioides immitis. Analyses of the cytokine profiles of two inbred mouse strains which differ in their susceptibility to pulmonary challenge with C. immitis revealed higher levels of IL-6 in lungs from DBA/2 mice (resistant strain) than in those from BALB/c mice (susceptible strain) beginning at day 6 and continuing through day 15 postinfection. Spleen cells from both mouse strains secreted TNF-α, IL-1α, and IL-6 in vitro in response to stimulation with killed spherules but differed in that spleen cells from the resistant strain produced increased levels of these cytokines earlier after pulmonary challenge and at increased levels throughout the course ...
Epidemiology. Coccidioidomycosis is caused by a soil-dwelling fungus that consists of two species, Coccidioides immitis and Coccidioides posadasii. Most cases of coccidioidomycosis in HIV-infected individuals have been reported in the areas in which the disease is highly endemic.1 In the United States, these areas include the lower San Joaquin Valley and other arid regions in southern California; much of Arizona; the southern regions of Utah, Nevada, and New Mexico; and western Texas.2 Recently, cases of coccidioidomycosis that appeared to be acquired in eastern Washington state have been reported.3 Whether this is anomalous or is a manifestation of an expanding area of endemicity is not clear at this time. In some instances, coccidioidomycosis has been diagnosed in patients with HIV infection well outside the known endemic regions. These have presumably been the result of reactivation of a previously acquired infection.. The risk of developing symptomatic coccidioidomycosis after infection is ...
Coccidioidomycosis (/kɒkˌsɪdiɔɪdoʊmaɪˈkoʊsɪs/, kok-sid-ee-oy-doh-my-KOH-sis), commonly known as cocci, valley fever, as well as California fever, desert rheumatism, and San Joaquin Valley fever, is a mammalian fungal disease caused by Coccidioides immitis or Coccidioides posadasii. It is endemic in certain parts of Arizona, California, Nevada, New Mexico, Texas, Utah, and northern Mexico. ...

TY - JOUR. T1 - Coccidioidomycosis. T2 - Clinical Update. AU - Ampel, Neil M.. AU - Wieden, Manon A.. AU - Galgian, John N.. PY - 1989/11. Y1 - 1989/11. N2 - Over the last decade coccidioidomycosis, a fungal infection endemic to the desert Southwest of the United States, has gained national prominence. This review summarizes recent advances in the clinical understanding of this disease. Immunosuppressive therapy and infection with the human immunodeficiency virus are recognized risk factors for the development of severe, progressive disease. Although relatively uncommon, extrapulmonary dissemination of Coccidioides immitis can lead to chronic infection ofthe skin, bones, and meninges. Culture and histologic examination are important in establishment of the diagnosis, but serologic tests remain both diagnostically and prognostically useful. lteatment is problematic. Coccidioidomycosis is an unpredictable disease, and assessments of drug efficacy are difficult. Ketoconazole is challenging ...
Coccidioidomycosis, also called Valley Fever, is an infection caused by the fungus Coccidioides. The disease is also sometimes called San Joaquin Valley fever or desert rheumatism. The term Valley Fever usually refers to Coccidioides infection in the lungs, but the infection can spread to other parts of the body in severe cases (this is called disseminated coccidioidomycosis).. ...

Coccidioidomycosis is a fungal infection caused by the endemic fungus Coccidioides species and is acquired through inhalation of airborne arthrospores within the endemic areas of the southwest US, northern Mexico, and limited areas of Central and South America. Both humans and animals may become infected. Coccidioidomycosis may be asymptomatic or can cause acute and chronic pulmonary syndromes and, rarely, extrapulmonary infection. No human-to-human transmission of infection occurs. ...

Community-acquired pneumonia (CAP) often results in severe illness and death. In large, geographically defined areas where Coccidioides spp. are endemic, coccidioidomycosis is a recognized cause of CAP, but its frequency has not been studied extensively. To determine the frequency of patients with coccidioidomycosis, we conducted a prospective evaluation of 59 patients with CAP in the Phoenix, Arizona, area. Of 35 for whom paired coccidioidal serologic testing was performed, 6 (17%) had evidence of acute coccidioidomycosis. Coccidioidal pneumonia was more likely than noncoccidioidal CAP to produce rash. The following were not found to be risk factors or reliable predictors of infection: demographic features, underlying medical conditions, duration of time spent in disease-endemic areas, occupational and recreational activities, initial laboratory studies, and chest radiography findings. Coccidioidomycosis is a common cause of CAP in our patient population. In the absence of distinguishing ...
Infection with Coccidioides immitis, a soil-inhabiting fungus native to the San Joaquin Valley in California, causes an illness in humans called coccidioidomycosis. Growth of C immitis occurs in 2 phases: (1) the mycelial arthrospore phase in the soil and (2) the spherule-endospore phase in infected tissues.
Each year, the etiologic agents, Coccidioides immitis and C. posadasii, cause Valley Fever in tens of thousands of individuals. While it widely accepted that this fungal disease is endemic to arid locations, such as the southwestern United States, the recent discovery of endemic clusters in Washington state suggests an expansion of the geographic range. Here, we present a whole genome analysis of 86 genomes, where 68 are unique to this study. The incorporation of Bayesian phylogenetics resulted in the identification of phylogeographic structure of both species, and calibrations on the root node reveal that C. posadasii is the more ancient of the two species. Taken together, we propose that C. posadasii originated near the Arizona-Mexico border, and we suggest a subsequent dispersal mechanism and route of spread.. ...

TY - JOUR. T1 - Coccidioidomycosis in liver transplant recipients relocating to an endemic area. AU - Blair, Janis E.. AU - Douglas, David D.. PY - 2004/11. Y1 - 2004/11. N2 - Coccidioidomycosis is an endemic fungal infection of the desert southwestern United States. This infection occurs at a rate of 1% to 8% in solid organ transplant recipients residing in the endemic area, and it has a high rate of disseminated infection and mortality. The risk of infection among transplant recipients from nonendemic areas visiting or moving to an endemic region is not known. We reviewed the clinical course of 41 liver transplant recipients who originally resided in and underwent liver transplantation in an area of low coccidioidal endemicity and who later relocated their follow-up care to our program, which is located in an endemic area. No patients received antifungal prophylaxis to prevent primary coccidioidomycosis. Among 37 patients with at least 1 year of follow-up care, the incidence of new ...
For patients with clinically mild infection, such as focal pneumonia, or who have a positive coccidioidal serologic test alone, initial therapy with a triazole antifungal is appropriate (BII). Fluconazole or itraconazole at doses of 400 mg daily is recommended (636Galgiani JN, Ampel NM, Blair JE, et al. Coccidioidomycosis. Clin Infect Dis 2005;41:1217-23., 637Galgiani JN, Ampel NM, Catanzaro A, et al. Practice guideline for the treatment of coccidioidomycosis. Clin Infect Dis 2000;30:658-61.). Data are limited with regard to the newer triazoles, posaconazole and voriconazole, but these agents might be useful in cases that fail to respond to fluconazole or itraconazole. Voriconazole should be used cautiously with HIV PIs and efavirenz.. For patients with either diffuse pulmonary involvement or severely ill patients with extrathoracic disseminated disease, amphotericin B is the preferred initial therapy (AII) (636Galgiani JN, Ampel NM, Blair JE, et al.

One of the most well-known studies of fungal infection, first noted in the late 1890s and carrying into the 1940s by physicians and researchers, was valley fever. It was isolated to the region of the San Joaquin Valley in California, and affected over 450 farm labourers and trainee soldiers. Studies found the fungal pathogen Coccidioides immitus had became airborne and entered the body through inhalation. This research was significant for medical mycology history because it encouraged other researchers to study the effects of fungal pathogens on humans, and brought attention to fungal disease as a major player in human disease ...
Olorofim is currently an investigational compound under clinical development. It belongs to the orotomides, a new class of antifungal antibiotics with a new mechanism of action targeting DHODH, an enzyme essential in the pathway of de novo pyrimidine biosynthesis (18). This is a novel target, and the compound has shown potent in vitro and in vivo activity against several medically important molds, including several Aspergillus spp. (19-21, 23), the Scedosporium/Pseudallescheria species complex and Lomentospora spp. (24, 25), certain species of Fusarium, Penicillium spp., and Talaromyces marneffei (18), as well as the dimorphic human pathogens Coccidioides spp. (26).. We showed that olorofim controls the growth of seven Aspergillus spp. that have been documented from CGD patients with cases of IA, in contrast to several other commonly used antifungals. More importantly, olorofim therapy was effective in reducing mortality, pathology, GM levels, and fungal DNA loads in two different murine models ...

Dr. Kearney presented an interesting case of an individual with untreated HIV who presented with dyspnea found to have hypoxemic respiratory failure. The patients history of a significant period of time off antiretroviral therapy (,3 years), the severity of the presentation of hypoxemic respiratory failure, and the severity of the lymphopenia (CD4# ,35) data-preserve-html-node=true raised suspicion for opportunistic infection. Sputum and blood cultures for fungus subsequently returned positive for Coccidioides immitis. Treatment had been started for coccidioidomycosis empirically with an azole and was subsequently increased to include amphotericin B once cultures returned positive. Highly active antiretroviral therapy was begun on admission as well. The patients respiratory failure improved over the subsequent days, but unfortunately he developed recurrent hypoxemic respiratory failure and pseudosepsis concerning for IRIS. The differential for dyspnea in the HIV+ patient is myriad. However, ...

Silver-staining of immunoprecipitates extends the sensitivity of the radial immunodiffusion assay by tenfold. This modification permits the quantification of apolipoproteins A-I, A-II, C, and E at levels of 0.2-1.0 mg/dl in plasma samples at a sensitivity threshold of 10 ng. The silver-enhanced radial immunodiffusion method is readily adapted from the standard method, simple and inexpensive to perform, and does not require costly instrumentation. These advantages make the modified RID assay an attractive alternative to other forms of immunoassay.
