Samples of ambient air collected with three different types of spore traps in a rural location were examined for the presence of Pneumocystis carinii by screening for P. carinii-specific DNA sequences by DNA amplification. Eleven spore trap samples were analyzed by nested PCR, using oligonucleotide primers designed for the gene encoding the mitochondrial large subunit rRNA of P. carinii f. sp. carinii and P. carinii f. sp. hominis. The samples were collected over a 3-year period during the months of May to September, with a range of sampling times from 9 to 240 h. One air sample from an animal facility housing P. carinii-infected rats was also examined. P. carinii-specific amplification products were obtained from samples from each of the spore traps. The amplification products from eight air samples were cloned and sequenced. The majority of the recombinants from each of these samples had sequences identical to those of P. carinii f. sp. carinii and P. carinii f. sp. hominis, and a number of ...
Pneumocystis is a fungal genus that contains multiple species. One member of the genus that has not been formally analysed for its phylogenetic relationships and possible species status is the Pneumocystis found in laboratory mice, Pneumocystis murina sp. nov. (type strain ATCC PRA-111T=CBS 114898T), formerly known as Pneumocystis carinii f. sp. muris. To advance research in this area, approximately 3000 bp of additional DNA sequence were obtained from the locus encoding rRNAs. This sequence and others were used to determine genetic distances between P. murina and other members of the genus. These distances indicated that P. murina DNA is most similar to that of the species of Pneumocystis found in laboratory rats. Nevertheless, P. murina is at least as diverged from these other Pneumocystis species as species in other fungal genera are from each other. The 18S rRNA gene sequence divergence exhibited by P. murina could not be ascribed to accelerated evolution of this gene as similar levels of divergence
Pneumocystis carinii pneumonia remains a major cause of morbidity and mortality in human immunodeficiency virus-infected individuals, despite the widespread use of prophylaxis and the development of new chemotherapeutic agents. The study of P. carinii and of pulmonary host defenses directed against it has been limited by lack of reliable, reproducible methods to obtain pure populations of organisms in useful quantities. While recent success has been achieved with cultures of rat P. carinii organisms, cultures of mouse P. carinii organisms have not been successful. Experiments were performed to determine whether P. carinii organisms derived from mice could be propagated in vitro. Mouse P. carinii organisms, obtained from the lungs of chronically infected athymic mice, were inoculated into spinner flasks containing HEL299 feeder cells seated on microcarrier beads. The numbers of mouse P. carinii organisms increased significantly over 7 days in culture. To test the viability and pathogenicity of ...
Summary Sera from patients with likely and possible Pneumocystis carinii pneumonia (PCP) on the basis of clinical information and laboratory investigations were tested by immunoblotting to assess the usefulness of trophozoites in the serodiagnosis of PCP. IgG antibodies to 50-60- kDa proteins were demonstrated with cyst antigen, but antibodies to additional proteins of 61, 70, 82, 95, 99 and 116 kDa were found with trophozoite antigen. These bands were not demonstrated with control sera. IgG antibody to the 116-kDa protein was found in 18 (46%) of 39 sera from patients with possible PCP compared with 5 (17%) of 30 sera from patients with likely PCP. There was no other significant difference between the two patient groups in detection of these proteins. Sera with higher indirect immunofluorescence assay (IFA) IgG titres were more likely to be immunoblot positive. Only 4 of 16 patients with likely PCP were IgG negative in the IFA; three of these were IgG immunoblot positive. In 4 of 10 patients with
Iron plays a critical role in host-parasite interactions, and iron chelators have been demonstrated to serve as effective adjunct therapeutic agents against malaria. The effects of the parenteral iron chelator deferoxamine (DFO) on the growth of rat-derived Pneumocystis carinii were studied in a human fibroblast cell culture model and in two in vivo models of experimental infection. In addition, the effects of the investigational oral iron chelator CP20 and its 3-hydroxypyridin-4-one analogs CP51, CP94, and CP96 on the growth of P. carinii in vitro were assessed. DFO suppressed the growth of P. carinii in vitro in a dose-dependent manner, and daily injections of DFO markedly reduced the intensity of P. carinii infection in both mice and rats. Cell cultures treated with iron chelators that are administered orally to humans also showed substantial P. carinii growth inhibition. Reduction of P. carinii numbers after iron chelator therapy correlated with alterations in P. carinii morphology, as ...

N2 - Pneumocystis is an important fungal pathogen that causes life-threatening pneumonia in patients with AIDS and malignancy. Lung fungal pathogens are recognized by C-type lectin receptors (CLRs), which bind specific ligands and stimulate innate immune responses. The CLR Dectin-1 was previously shown to mediate immune responses to Pneumocystis spp. For this reason, we investigated a potential role for Dectin-2. Rats with Pneumocystis pneumonia (PCP) exhibited elevated Dectin-2 mRNA levels. Soluble Dectin-2 carbohydrate-recognition domain fusion protein showed binding to intact Pneumocystis carinii (Pc) and to native Pneumocystis ...

A. Statement of Hypotheses:. HIV-infected patients have an increased incidence of emphysema compared to non-HIV-infected smokers, and it has been hypothesized that this accelerated disease progression is the result of one or more latent infections that amplifies the pulmonary inflammatory response to cigarette smoke. Pneumocystis is one infectious agent that likely plays a key role in the development of HIV-associated emphysema. Colonization with Pneumocystis has been demonstrated in HIV-infected subjects, and HIV-infected smokers are particularly susceptible to Pc colonization regardless of CD4 cell count or use of prophylaxis. Pneumocystis colonization is also increased in non-HIV-infected patients with chronic obstructive pulmonary disease (COPD) and is directly related to the severity of the disease. The presence of Pneumocystis in the lungs, even at low levels as seen in colonization, produces inflammatory changes similar to those seen in COPD, with increases in the numbers of neutrophils ...

Pneumocystis carinii was propagated in vitro with primary embryonic chick epithelial lung (CEL) cells. Viability and growth of the organism were demonstrated by direct observation of the reproductive cycle in the Sykes-Moore chamber, serial passage with an increase in the number of mature cysts forms, the cytopathic effect of the organism on cell culture, and inhibition of growth of the organism by specific antiserum and pentamidine isethionate. Attempts to culture P. carinii indefinitely were not successful. However, cyst forms derived from murine and human sources increased 100-fold and 10-fold, respectively, during CEL cell culture passages. Serial passage of trophozoites alone resulted in the development of typical CPE and a maximum number of 2.8 X 10(3) cyst forms. Autoradiographic methods demonstrated active DNA, RNA, and protein synthesis within the cyst and suggest that metabolic interaction between the host cells and the organisms occurred. The nature of the attachment of P. carinii to ...
Our thanks to Dr. Melanie T. Cushion for her comments on the life cycle text.. This is a generalised life cycle proposed by John J. Ruffolo, Ph.D. (Cushion, MT, 1988) for the various species of Pneumocystis. These fungi are found in the lungs of mammals where they reside without causing overt infection until the hosts immune system becomes debilitated. Then, an oftentimes lethal pneumonia can result. Asexual phase: trophic forms replicate by mitosis. Sexual phase: haploid trophic forms conjugate and produce a zygote or sporocyte (early cyst). The zygote undergoes meiosis and subsequent mitosis to produce eight haploid nuclei (late phase cyst). Spores exhibit different shapes (such as, spherical and elongated forms). It is postulated that elongation of the spores precedes release from the spore case. It is believed that the release occurs through a rent in the cell wall. After release, the empty spore case usually collapses, but retains some residual cytoplasm. A trophic stage, where the ...
To the editor: Extrapulmonary dissemination of Pneumocystis carinii is rare. To our knowledge, P. carinii infection of the bone marrow has been reported in only three patients, each having a nonmalignant immunodeficiency syndrome (1-3). Conversely, P. carinii pneumonia occurs frequently in homosexual men who have T-cell immunodeficiency (4) as well as in patients with various malignancies after chemotherapy (5). However, infection with this organism has not been described in the bone marrow of patients with lymphoma. We report the cases of two patients with lymphoma who had such infections and propose bone marrow biopsy as a routine examination to confirm ...
Two sources of rats free of latent Pneumocystis carinii are described. First, rats from a virus-free colony failed to develop infection after 8 weeks of immune suppression unless they were housed with previously infected rats. Second, pregnant rats (non-virus free) received trimethoprim-sulfamethoxazole from day 10 of gestation until the pups were weaned. Pups raised in filter-topped cages and immunosuppressed for 8 weeks were free of P. carinii infection. ...

Screening for this agent in rodents in research studies can be important for obtaining reliable and interpretable results. Because this pathogen occurs widely in the environment, many animals have been exposed to it and serology testing is therefore unable to reliably determine animals current carrier status. Detection of this pathogen by PCR is useful because this technique is very sensitive and specific. Results will not be compromised if the infection is at early stage or the animal is immunodeficient. ...

To address the potential role of such a G protein in Pneumocystis, PcCdc42 was cloned from a Pc cDNA library. Using the full-length 576-bp PcCdc42 cDNA sequence, a CHEF blot of genomic DNA yielded a single band, providing evidence that this gene is ...
The nonspecific histopathologic changes of diffuse alveolar damage (DAD) were the only findings in nine of 17 lung biopsy specimens containing Pneumocystis carinii infection. Because of the frequent absence of the classically described intra-alveolar frothy material, special stains for organisms should be performed on all biopsy specimens from immunocompromised patients that show DAD, and the diagnosis of Pneumocystis infection should not be discarded unless careful search for organisms using special stains is negative. ...
Glycosphingolipid (GSL) Lactosyl Ceramide (LacCer) is thought to be involved in Pneumocystis interaction with the host. Our previous results show that treatment with glycosphingolipid synthesis inhibitor PDMP reduces the fungus lung burden as well as symptoms of inflammation in mice with Pneumocystis pneumonia (PCP). Experiments were set up to resolve whether anti-inflammatory effects were due to the specific mechanisms involved in innate immune responses to Pneumocystis, or to some general anti-inflammatory property of PDMP. Animals were infected with live organisms, or challenged with either beta-glucan (the pro-inflammatory component of Pneumocystis cell wall) or LPS (inducer of lung inflammation unrelated to Pneumocystis). At the experimental endpoint the following inflammatory parameters were assessed: leukocyte recruitment to the lungs, production of pro-inflammatory cytokines and chemokines, histopathology and lung damage. Results show that glucan-induced acute inflammation partially ...
Summary Pneumocystis carinii pneumonia (PCP) is the most common opportunistic infection in children who have acquired immunodeficiency syndrome (AIDS). Despite the publication of guidelines for prophylaxis against PCP for children infected with human immunodeficiency virus (HIV) in 1991 (1), ongoing AIDS surveillance has detected no substantial decrease in PCP incidence among HIV-infected infants. Studies indicate that this continued incidence is associated with failure to identify HIV-infected children before PCP occurs and with limitations in the ability of CD4+ measurements to identify children at risk for PCP. In March 1994, the National Pediatric & Family HIV Resource Center, * in collaboration with CDC, convened a working group to review additional data about the occurrence of PCP among HIV-infected children and to reevaluate the 1991 PCP prophylaxis guidelines for children. This report summarizes these new data and presents revised PCP prevention guidelines that recommend a) promptly ...
Pneumocystis carinii pneumonia (PCP), the most common presenting manifestation of the acquired immunodeficiency syndrome (AIDS), is a major and recurring cause of morbidity and mortality for persons infected with the human immunodeficiency virus (HIV). In recent years, important advances have been made in understanding which patient subpopulations are athighest risk for developing PCP and in the design of chemotherapeutic regimens that can reduce the frequency of this illness. Recently, a number of experts* convened by the National Institutes of Health independently reviewed data on prophylaxis against PCP among persons infected with HIV, and then provided recommendations to the U.S. Public Health Service concerning which persons should receive prophylaxis and what specific prophylactic regimens should be used. The resulting guidelines are detailed below. BACKGROUND Since the early 1980s, management of PCP has become increasingly successful, and several effective chemotherapeutic regimens are ...

The disease PCP is relatively rare in people with normal immune systems, but common among people with weakened immune systems, such as premature or severely malnourished children, the elderly, and especially persons living with HIV/AIDS (in whom it is most commonly observed).[1][10] PCP can also develop in patients who are taking immunosuppressive medications. It can occur in patients who have undergone solid organ transplantation or bone marrow transplantation and after surgery.[11] Infections with Pneumocystis pneumonia are also common in infants with hyper IgM syndrome, an X-linked or autosomal recessive trait. The causative organism of PCP is distributed worldwide[12] and Pneumocystis pneumonia has been described in all continents except Antarctica.[12] More than 75% of children are seropositive by the age of 4, which suggests a high background exposure to the organism. A post mortem study conducted in Chile of 96 persons who died of unrelated causes (suicide, traffic accidents, and so ...

Pneumocystis carinii pneumonia is a leading cause of morbidity and mortality in patients with the acquired immunodeficiency syndrome (AIDS). Much remains unknown about the basic biology of P. carinii and studies of this infection have been hampered by the lack of cultivation methods. We developed a sensitive and specific assay for P. carinii by utilizing DNA amplification of the P. carinii dihydrofolate reductase (DHFR) gene. By this method, P. carinii DNA was detected in the lungs of rats with experimentally induced P. carinii pneumonia 2 wk before the onset of histopathological changes. DNA amplification analysis of serum demonstrated that by 10 wk of corticosteroid treatment, 12 of 12 (100%) infected rats had circulating DHFR DNA. P. carinii DHFR DNA also was detected in the serum of patients with AIDS and active P. carinii pneumonia (12 of 14 sera collected prospectively). Patients with advanced AIDS but without a history of P. carinii pneumonia were negative by this assay (0 of 6 sera ...
SPN : Pneumocystis jiroveci is one of the major microbial pathogens associated with opportunistic pulmonary infections in patients receiving immunosuppressive therapy or with immune deficiencies. Presently, the most common means to diagnose Pneumocystis jiroveci infection is by microscopic detection of the organisms in specimens such as bronchoalveolar lavage, open lung biopsy tissue, induced sputum and transtracheal aspirate.
Pneumocystis pneumonia or PCP is a fungal infection in one or both lungs. It is common in people who have a weak immune system, such as people who have AIDS.

True polyploidy rarely occurs in humans, although polyploid cells occur in highly differentiated tissue, such as liver parenchyma, heart muscle, placenta and in bone marrow.[1][48] Aneuploidy is more common. Polyploidy occurs in humans in the form of triploidy, with 69 chromosomes (sometimes called 69, XXX), and tetraploidy with 92 chromosomes (sometimes called 92, XXXX). Triploidy, usually due to polyspermy, occurs in about 2-3% of all human pregnancies and ~15% of miscarriages.[citation needed] The vast majority of triploid conceptions end as a miscarriage; those that do survive to term typically die shortly after birth. In some cases, survival past birth may be extended if there is mixoploidy with both a diploid and a triploid cell population present. There has been one report of a child surviving to the age of seven months with complete triploidy syndrome. He failed to exhibit normal mental or physical neonatal development, and died from a Pneumocystis carinii infection, which indicates a ...
The development of a granulomatous histological reaction in PCP is unusual, occurring in only 3% of the cases of PCP identified in patients with malignancy at our institution. All of these patients had expected risk factors for development of PCP but they had atypical clinical features. The presentation was insidious with very minimal symptoms and the radiographs showed a reticulonodular pattern rather than the expected interstitial-alveolar infiltrates. This pattern is more characteristic of HIV infected patients than of those with malignancy where the presentation is often subacute to fulminant and dyspnoea is the prominent symptom.6 In addition, an increased serum level of LDH, which is a sensitive marker for the presence of PCP, was not found in our patients.7 The LDH level was normal or only slightly raised.. The unexpected finding of most clinical significance was the non-diagnostic bronchoscopy in all cases, even in the two cases from whom transbronchial biopsy specimens were taken in ...
Methods of treating Pneumocystis carinii pneumonia comprise administering a therapeutically effective amount of a dicationic dibenzofuran compound described by Formula (I). Methods of treating Pneumocystis carinii pneumonia also comprise administering a therapeutically effective amount of a dicationic dibenzothiophene compound described by Formula (II). Novel compounds are also disclosed, and are represented by the Formulae (I) and (II).

PCP is a rare disease in healthy people. However, it can be serious in those who have AIDS, cancer, or other conditions that weaken the immune system.. PCP is one of the most common pediatric illnesses associated with AIDS, especially in babies younger than 6 months old. Its prevention is very important in AIDS care since it is a leading cause of death in people with AIDS.. In kids who are already seriously ill, symptoms of this form of PCP begin suddenly with a fever, a cough, and difficulty breathing. A child may not cough up any mucus because it is usually too thick to come up with the cough. Other symptoms can include weight loss and night sweats.. Babies who are already sick or have a weakened immune system also can develop PCP. In most cases, the baby is 3 to 6 months old and has no fever, but gradually begins to breathe faster than normal. As the lung infection gets worse, breathing becomes more difficult, and the babys chest muscles may begin to retract (pull in abnormally) with each ...
Could the coronavirus be interfering with the immune system in a way that is allowing Pneumocystis pneumonia to thrive?. A: Yes. COVID has been linked to CD4+ (T helper) lymphopenia, possible via cytokine storm. The main risk factor for PCP is CD4+ lymphoooenia caused by HIV.. My understanding is that Pneumocystis pneumonia, otherwise known as PJP or PCP, is caused by a fungus. It is highly opportunistic, and is rarely seen in people with healthy immune systems. It is highly associated with AIDS/HIV. A: Its actually rarely seen with HIV these days (due to ART), useally in transplant or immunosupressed patients.. The fungus that causes it is widespread, and likely exists in the lungs of most healthy people.. I'm not sure about this one, but it seems relatively difficult to test for. Given it's rarity, it seems it is most are assumed to have it if they present symptoms and are positive for HIV/AIDS. If they are suspected, it seems they test for HIV/AIDS first.. A: It is easy to test for ...
