The experiments recorded above show that in the case of antipneumococcus horse serum or purified antibody the arbitrary immunological procedure (37° for 2 hours, overnight in the ice box) does not permit either the establishment of a true equilibrium or the precipitation of the maximum amount of antibody nitrogen. Analyses of such horse sera for antibody content should therefore be carried out at 0° and the determinations should be allowed to stand in the cold for at least 24 hours in order to insure the completion of the reaction.. It is believed that the similarity of the nitrogen: S III ratios in the specific precipitate, whether obtained from whole serum or from purified antibody, and the failure of added serum to influence the amount of nitrogen precipitated show that the absolute chemical method for the estimation of antibody actually measures antibody and not antibody plus a more or less indefinite amount of non-specific protein. An objection to the use of the method is thus shown to be ...
IgG titers (seroconversion of 4× rise). • Skin tests (coccidioidin and spherulin) good for epidemiologic studies, not for diagnosis of acute disease. • C immitis early to grow in culture but hazardous to handle. • Spherule identification in tissue, lavage samples helpful in diagnosis. • Pap staining most sensitive (Gram stains fail to demonstrate spherules) ...
CASE REPORT. A 31 year old white male cement finisher entered the hospital January 3, 1956, because of progressively increasing cough over the previous year, productive of a small amount of white to yellow sputum without hemoptysis. In November, 1955, the patient had sought medical attention because of nocturnal cough, and a roentgenogram of the chest revealed a milky spot. Tuberculin and coccidioidin skin tests were said to be negative at this time. Hospitalization was recommended but refused by the patient. On admission the patient complained ...

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,

AU - Lake, D. F.. PY - 2001/11/1. Y1 - 2001/11/1. N2 - Coccidioidomycosis, an infection endemic to the southwestern United States, is caused by the fungus Coccidioides immitis. 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 ...

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 ...

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. ...
Immunologically reactive proteins in acid extracts and culture supernatants of Streptococcus equi were recognized through a combination of chromatographic and immunologic procedures. Both high- and low-molecular-weight components of each of these protein preparations were protective for mice and were, therefore, presumed to contain a variety of hydrolytic products or fragments of the M protein of S. equi. Convalescent horse sera that exhibited strong bactericidal activity for S. equi always reacted with polypeptides in the molecular weight range of 24,000 to 29,000, whereas preinfection sera did not. Rabbit antisera to affinity-purified S. equi protein also reacted with these polypeptides, as well as with a polypeptide of about 36,000 to 37,000 molecular weight. M protein in acid extract and culture supernatant did not cross-react in immunodiffusion, but rabbit antiserum to affinity-purified M protein from an acid extract of S. equi reacted strongly with culture supernatant proteins of ...

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.
TY - JOUR. T1 - Pulmonary coccidioidomycosis. AU - Thompson, George Richard. PY - 2011. Y1 - 2011. N2 - Coccidioidomycosis refers to the spectrum of disease caused by the dimorphic fungi Coccidioides immitis and Coccidioides posadasii. Clinical manifestations vary depending upon both the extent of infection and the immune status of the host. Coccidioidomycosis has been reported to involve almost all organ systems; however, pulmonary disease is the most common clinical manifestation. The incidence of coccidioidomycosis continues to rise, and primary coccidioidal pneumonia accounts for 17 to 29% of all cases of community-acquired pneumonia in endemic regions. The majority of patients with coccidioidomycosis resolve their initial infection without sequelae; however, several patients develop complications of disease ranging in severity from complicated pulmonary coccidioidomycosis to widely disseminated disease with immediately life-threatening manifestations. This review focuses on complications of ...
A method has been devised for the electrophoretic transfer of proteins from polyacrylamide gels to nitrocellulose sheets. The method results in quantitative transfer of ribosomal proteins from gels containing urea. For sodium dodecyl sulfate gels, the original band pattern was obtained with no loss of resolution, but the transfer was not quantitative. The method allows detection of proteins by autoradiography and is simpler than conventional procedures. The immobilized proteins were detectable by immunological procedures. All additional binding capacity on the nitrocellulose was blocked with excess protein; then a specific antibody was bound and, finally, a second antibody directed against the first antibody. The second antibody was either radioactively labeled or conjugated to fluorescein or to peroxidase. The specific protein was then detected by either autoradiography, under UV light, or by the peroxidase reaction product, respectively. In the latter case, as little as 100 pg of protein was ...

The 2014/15 influenza season to date in Canada has been characterised by predominant influenza A(H3N2) activity. Canada's Sentinel Physician Surveillance Network (SPSN) assessed interim vaccine effectiveness (VE) against medically attended, laboratory-confirmed influenza A(H3N2) infection in January 2015 using a test-negative case-control design. Of 861 participants, 410 (48%) were test-positive cases (35% vaccinated) and 451 (52%) were test-negative controls (33% vaccinated). Among test-positive cases, the majority (391; 95%) were diagnosed with influenza A, and of those with available subtype information, almost all influenza A viruses (379/381; 99%) were A(H3N2). Among 226 (60%) A(H3N2) viruses that were sequenced, 205 (91%) clustered with phylogenetic clade 3C.2a, considered genetically and antigenically distinct from the 2014/15 A/Texas/50/2012(H3N2)-like clade 3C.1 vaccine reference strain, and typically bearing 10 to 11 amino acid differences from the vaccine at key antigenic sites of the

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.

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 ...

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

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, ...
In 2002, the prevalence of bovine tuberculosis (tb) among 500 cattle on Holeta Farm, near Addis Ababa, Ethiopia, was 48 per cent, and the farm was divided into positive and negative herds. After three consecutive rounds of skin testing and segregation of skin test-positive and -negative animals, the prevalence of bovine tb was reduced from 14 per cent to 1 per cent in the negative herd in a year. Spoligotyping of 41 isolates from 17 cows gave an identical and unique spoligotype pattern, which can be represented as the binary number 1100000101111110111111100010000000000100000, where 1 indicates the presence of a spacer and 0 represents a loss. This spoligotype pattern had not previously been reported on the Mycobacterium bovis spoligotype database, and it was therefore designated sb1176, Ethiopian M bovis strain 1 (embs1). The variable number tandem repeat (vntr) profile of the strain was 5254*33.1, which differed from the vntr profile of strains reported in Great Britain.. ...

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 ...

The AGID, or Coggins, test has been shown to correlate with horse inoculation test results for EIAv and therefore can be used to identify EIAv carriers. Although other serologic tests have been defined and approved for the diagnosis of EIA, the AGID test is recognized internationally as the gold standard serologic test. The use of AGID and additional tests has assisted in the control of EIA. Presently, USDA recognizes the AGID and a number of ELISA formats for conducting official tests. Controlling the spread of EIAv involves minimizing or eliminating contact of healthy horses with the secretions, excretions, and blood of EIAv-infected horses. Once the reservoirs of EIAv are identified, separated, and maintained a safe distance from the other horses, the transmission of EIAv is broken. Until all horses are tested, precautions should be taken to prevent commingling with horses that do not originate from test-negative farms or that have been exposed to test-positive horses. All diagnostic ...
