Summary and Conclusion 1. The results of a survey of skin sensitivity to histoplasmin, coccidioidin and tuberculin on the north coast of Honduras are reported. 2. Of 421 hospitalized patients, the histoplasmin skin test was positive in 47.7 per cent, doubtful in 5.2 per cent, and negative in 47.1 per cent. The coccidioidin skin test was positive in 1.0 per cent, doubtful in 2.1 per cent, and negative in 96.9 per cent. 3. Of 360 patients tested with tuberculin (P.P.D. 0.005 mg.), the result was positive in 89.5 per cent, doubtful in 2.2 per cent, and negative in 8.3 per cent. 4. Pulmonary calcifications were present in 84 (59.2 per cent) of 142 selected patients. Of these, 45.2 per cent were tuberculin positive, histoplasmin negative; 42.9 per cent were tuberculin positive, histoplasmin positive; 8.3 per cent were tuberculin negative, histoplasmin positive; and 3.6 per cent were negative to both. 5. These results suggest that, in addition to the high prevalence of tuberculosis in this area,
Summary The range of histoplasmin sensitivity in 821 Guatemalan hospital patients between the ages of 15 and 60 years of age was found to be 23 to 81% depending on the test area. The uniformity of histoplasmin sensitivity rates in all age groups tested suggests that most infections are acquired prior to age 15. The ratio of males to females was approximately 5 to 3, with sensitivity rates of 62 and 49 per cent, respectively.

The syndrome described here demonstrates an ophthalmic feature similar to that seen in patients suffering from presumed ocular histoplasmosis in the USA. We report 81 patients who fulfilled the clinical criteria for presumed ocular histoplasmosis, including 51 patients exhibiting the classic clinical picture which was identical to the entity as described in the USA. Thirty patients had an incomplete form, as they did not show numerous histospots. Nevertheless, there are some differences in clinical features when comparing our patients with those described in the USA.. Our patients do not come from an area endemic for histoplasmosis, which is usually the case for diagnosis in the USA.136 In seven patients, the results of histoplasmin skin testing were available, and it was negative in all patients. Diagnosis by histoplasmin skin testing has been abandoned since it was suggested that there was a possibility of flare up of maculopathy in 7%.37 There is a predominance of females in our group, which ...

Histoplasmosis (also known as Cave disease, Darlings disease, Ohio valley disease, reticuloendotheliosis, spelunkers lung and cavers disease) is a disease caused by the fungus Histoplasma capsulatum. Symptoms of this infection vary greatly, but the disease affects primarily the lungs. Occasionally, other organs are affected; this is called disseminated histoplasmosis, and it can be fatal if left untreated. Histoplasmosis is common among AIDS patients because of their suppressed immunity. In immunocompetent individuals, past infection results in partial protection against ill effects if reinfected. Histoplasma capsulatum is found in soil, often associated with decaying bat guano or bird droppings. Disruption of soil from excavation or construction can release infectious elements that are inhaled and settle into the lung. If symptoms of histoplasmosis infection occur, they will start within 3 to 17 days after exposure; the average is 12-14 days. Most affected individuals have ...
This booklet is a revised edition of the NIOSH document Histoplasmosis:Protecting Workers at Risk, which was originally published in September 1997. The updated information in this booklet will help readers understand what histoplasmosis is and recognize activities that may expose workers to the disease-causing fungus Histoplasma capsulatum. The booklet also informs readers about methods they can use to protect themselves and others from exposure.. Outbreaks of histoplasmosis have shared similar circumstances:People who did not know the health risks of breathing in the spores of H. capsulatum became ill and sometimes caused others nearby to become ill when they disturbed contaminated soil or accumulations of bird or bat manure. Because they were unaware of the hazard, they did not take protective measures that could have prevented illness.. Histoplasmosis - Protecting Workers at Risk [PDF 677KB ...

Histoplasmosis is worldwide systemic mycoses caused by the dimorphic fungus Histoplasma capsulatum. The isolation and identification of H. capsulatum in culture is the reference test for histoplasmosis diagnosis confirmation. However, in the absence of it, serology has been used as a presumptive diagnosis through antibody and antigen detection. The purpose of the present study was to validate an immunoassay method (western blot) for antibodies detection in the diagnosis of histoplasmosis. To validate the western blot (WB) a study was conducted using 118 serum samples from patients with histoplasmosis and 118 serum controls collected from January 2000 to December 2013 in residents of the Rio de Janeiro State, Brazil. Diagnostic validation parameters were calculated based on the categorization of results obtained in a 2 × 2 table and subjected to statistical analysis. In addition, the viability of deglycosylated histoplasmin antigen (ptHMIN) onto nitrocellulose membranes previously sensitized was

Histoplasmosis is a systemic disease that affects the bone marrow, lungs, liver, and spleen, mostly by involving the reticuloendothelial system, with hematogenous spread being the primary mechanism of dissemination.4 Geographically, histoplasma capsulatum is mostly concentrated in the Ohio, Missouri, and Mississippi river valleys.5,6 Immunocompetent individuals have clinically silent infections and recover without any medical intervention. Immunosuppression is the number one cause of histoplasmosis manifesting as a syndrome, and most cases are reported in the AIDS-affected population.2,5 Transplant recipients are the second population with an increased incidence of reported histoplasmosis.7 The diseases clinical presentation is variable. Pulmonary involvement as acute or chronic pulmonary disease in the form of pneumonia, pulmonary nodules, cavitary lung disease, and broncholithiasis is the most common presentation. The disseminated disease can present with rheumatological, dermatological, and ...

In Mexico, primary pulmonary histoplasmosis is the most relevant clinical form of the disease. The geographical distribution of specific strains of Histoplasma capsulatum circulating in Mexico has not been fully established. Outbreaks must be reported in order to have current, updated information on this disease, identifying new endemic areas, manner of exposure to the fungi, and molecular characterization of the causative agents. We report a recent outbreak of histoplasmosis in treasure hunters and the molecular characterization of two isolates obtained from these patients. Six patients admitted to the National Institute of Respiratory Diseases (INER) in Mexico City presented severe respiratory symptoms suggestive of histoplasmosis. They acquired the infection in the Veracruz (VZ) endemic zone. Diagnosis was made by X-ray and Computed tomography (CT), liver function, immunological techniques, and culture. Identification of H. capsulatum isolates was confirmed by using Polymerase chain reaction (PCR)
Histoplasmosis is a serious opportunistic infection in persons with AIDS that demonstrates an excellent response to antifungal therapy. However, until the advent of highly active antiretroviral therapy (HAART), patients with histoplasmosis required lifelong suppressive antifungal therapy. It is thought that immune reconstitution as a result of HAART may diminish the need for chronic therapy. Histoplasmosis offers an opportunity to examine the concept of discontinuation of maintenance therapy as it is rapidly diagnosed and effectively treated with itraconazole [AS PER AMENDMENT 9/27/00: or other appropriate therapy for disseminated histoplasmosis] should relapse occur.. Patients discontinue antifungal maintenance therapy. Patients are seen for routine visits every 8 weeks and urine and serum specimens are collected for real time Histoplasma antigen testing and immunologic parameters. Patients with suspected recurrence, as determined by clinical or routine laboratory findings consistent with ...

We have cloned an actin-encoding cDNA from the dimorphic fungus Histoplasma capsulatum, an important pathogen of humans. The predicted amino acid sequence as well as the general codon pattern of Histoplasma actin revealed the highest degree of similarity to the actin of the filamentous ascomycete Aspergillus nidulans. Southern blot analysis determined that actin was encoded by a single copy in the Histoplasma genome. Northern blot analysis showed a single 1700 nt transcript in yeast and mould cells as well as in cells undergoing the temperature induced mould-to-yeast conversion. Actin mRNA levels normalized to 18 S rRNA were found to be equivalent in all the stages examined, except for a sharp four-fold transient decrease 4 h into the mould-to-yeast conversion. These data suggest that actin mRNA would not be a suitable internal marker for expression studies during Histoplasma mould-to-yeast morphogenesis.
Histoplasma capsulatum is a dimorphic fungus that remains in a mycelial form at ambient temperatures and grows as yeast at body temperature in mammals. Infection causes histoplasmosis.
The complement fixation test is based on the use of complement, a biological substance present in the sera of normal animals. Its great value is its predictable activity in the presence of serologically reacting factors and its nonspecificity, that is, it is not like an antibody with a narrow range of reactions or increased concentration occurring in a host following immunization or infection. Furthermore, it is easily destroyed by heating at temperatures that have no deleterious effect on antibodies.
Histoplasmosis is a disease caused by a fungus (or mold.) The fungus is common in the eastern and central United States. It grows in soil and material contaminated with bat or bird droppings. You get infected by breathing the fungal spores. You cannot get the infection from someone else.. Histoplasmosis is often mild, with no symptoms. If you do get sick, it usually affects your lungs. Symptoms include feeling ill, fever, chest pains, and a dry cough. In severe cases, histoplasmosis spreads to other organs; this is called disseminated disease. Disseminated disease is more common in infants, young children, seniors, and people with immune system problems.. Tests for histoplasmosis include blood or urine tests and tissue samples. Chest x-rays and CT scans may also help to diagnose it. Mild cases usually get better without treatment. Treatment of severe or chronic cases is with antifungal drugs..

Histoplasmosis is a relatively common fungal infection in dogs and cats. Affected pet may have respiratory, eye, liver, and gastrointestinal complications.
The long-term goal of our research is to understand how the fungal pathogen Histoplasma capsulatum causes disease. H. capsulatum is a highly virulent pathogen that causes significant morbidity in both immunocompromised and immunocompetent individuals, with approximately 500,000 Histoplasma infections estimated to occur every year in the U.S. H. capsulatum is a pathogen of macrophages, which phagocytose microbes and digest them via an arsenal of microbicidal mechanisms. In contrast to most microbes, H. capsulatum replicates to high levels in the macrophage phagosome. Colonization of the macrophage is followed by host-cell death and release of live yeast cells, but the mechanism that triggers host-cell death is unknown. We have determined that the previously identified Histoplasma factor Cbp1 is dispensable for high intracellular fungal burden, but required for host-cell lysis. Additionally, our preliminary studies uncovered that Cbp1 is required to induce transcription of a specific and limited ...

The Northern blot method is used to detect specific RNAs that have been separated by size and immobilized onto a membrane (Fig 1). This method can provide specific information regarding the size of a sncRNA and possible precursor structures. Thus, it represents a valuable tool in the discovery and validation of new sncRNAs. In situ hybridization (ISH) is a technology that allows detection of specific nucleic acid sequences in tissue samples at the cellular level (Nielsen, 2012; Urbanek et al., 2015). For detection of individual sncRNA, the ISH technology determines the cellular origin of expression and provides information on expression levels in different tissue compartments and cell populations. This histological expression analysis is of crucial importance for elucidating roles particularly of sncRNAs in molecular and biological processes. ...

Histoplasma duboisii is a saprotrophic fungus responsible for the invasive infection known as African histoplasmosis. This species is a close relative of Histoplasma capsulatum, the agent of classical histoplasmosis, and the two occur in similar habitats. Histoplasma duboisii is restricted to continental Africa and Madagascar, although scattered reports have arisen from other places usually in individuals with an African travel history. Like, H. capsulatum, H. duboisii is dimorphic - growing as a filamentous fungus at ambient temperature and a yeast at body temperature. It differs morphologically from H. capsulatum by the typical production of a large-celled yeast form. Both agents cause similar forms of disease, although H. duboisii predominantly causes cutaneous and subcutaneous disease in humans and non-human primates. The agent responds to many antifungal drug therapies used to treat serious fungal diseases. Histoplasmosis was first reported from the African continent in 1942. These early ...
A 27 year old female with AIDS and disseminated histoplasmosis is presented. The clinical features include fever, weight loss, productive cough, splenomegaly and moderate pallor. The initial working diagnosis was pulmonary tuberculosis. The diagnosis of disseminated histoplasmosis was made terminally from bone marrow aspirate examination. Disseminated histoplasmosis with its varied clinical picture is likely to be missed in a patient with AIDS, and therefore a high index of suspicion is necessary for diagnosis. PIP: A 27-year old female from Nairobi was admitted to the medical wards of the Kenyatta National Hospital in May 1991. She presented with a 4-week history of productive cough, fever, weight loss, and night sweats. She acknowledged a history of contact with a patient known to have pulmonary tuberculosis. She has never received a blood transfusion. She was single and para 3 + 0. Examination revealed a sick patient, with moderate pallor, fever of 38 degrees Celsius, and who was wasted with ...
Histoplasma was initially described from a lesion in a horse by Rivolta in 1873, who named the organism Cryptococcus farciminosum. In 1905, Samuel Darling noted the presence of intracellular organisms in many tissues, including the lungs, of a patient suspected of succumbing to miliary tuberculosis (Darling 1906). Darling named the organism Histoplasma capsulatum , because it appeared to be an encapsulated protozoan-like organism. In 1912, mycologist Henrique da Rocha-Lima reviewed Darlings slides and noted the cytological similarities between Darlings Histoplasma organism and Cryptococcus farciminosum. Cryptococcus farciminosum was reclassified as Histoplasma farciminosum in 1934, and in 1985 it was again reclassified as a variant of Histoplasma capsulatum (var. farciminosum ) (Weeks et al. 1985).. William De Monbreun cultured the organism from the blood of a child suffering from an unexplained febrile disease in 1934, and demonstrated it to be a dimorphic fungus (De Monbreun 1934). De ...
The role of Yps3 in virulence has remained speculative since the identification of this protein in 1989. There is a correlation of YPS3 expression with pathogenicity, since only the most virulent strains of Histoplasma express YPS3 and only in the host-adapted yeast morphotype (2, 13). These observations were made with nonisogenic H. capsulatum strains, and the levels of Yps3 production were only one of many differences among the strains. In this study, we provide the first genetic evidence that the YPS3 gene of the restriction fragment length polymorphism class 2 strains of H. capsulatum influences virulence. We demonstrate that RNAi-silenced YPS3 mutants have a virulence defect in a mouse model of infection, although they grow normally as yeasts in vitro, can transition to the mycelial morphotype when the growth temperature is shifted to 25°C (data not shown), and appear normally virulent during the in vitro infection of RAW 264.7 macrophages.. In mice, Yps3 RNAi mutants were able to infect ...

Chronic obstructive pulmonary disease is characterized by a strong inflammatory response to inhalation of harmful irritating particles. Recruitment of immune cells that secrete cytokines, chemokines and proteases, consequently leads to airway obstruction and reduced air flow. TLR receptors are primarily responsible for innate immunity and they enhance the response of acquired immunity. There was a link between TLR receptors, activation (phosphorylation) of MAPK kinase (ERK, p38, JNK) and the secretion of various cytokines that cause an inflammatory response. TLR4 agonist (LPS) and TLR2 agonist (LTA) might be used for examination of the inflammatory response induced by these receptors. The aim of this study was the optimization of the conditions for determining the signaling molecules ERK and p38 MAPK from THP-1 cell lines by Western blot method. The results show that the optimal conditions and the best results for all the examined proteins ERK, p-ERK, p38 and p-p38 are achieved by using the ...
