Study of the epidemiology of Pneumocystis carinii f. sp. suis in abattoir swine in Portugal

Pneumocystis has been identified in various mammalian species, including domestic, wild and zoo animals. This study’s main objectives were: (1) to estimate the prevalence of the Pneumocystis carinii f. sp. suis infection in slaughtered pigs in Portugal, (2) assess the prevalence differences within distinct age groups of animals, (3) determine the possible associations between pulmonary lesions and the infection, and (4) genetically characterize the P. carinii f. sp. suis isolates recovered from infected animals using PCR with DNA sequencing.

Diagnosis of Pneumocystis pneumonia: evaluation of four serologic biomarkers

The diagnosis of Pneumocystis pneumonia (PCP) relies on microscopic visualization of Pneumocystis jiroveciiorganisms or DNA detection in pulmonary specimens. This study aimed to assess the usefulness of (1–3)-β-d-glucan (BG), Krebs von den Lungen-6 antigen (KL-6), lactate dehydrogenase (LDH) and S-adenosyl methionine (SAM) as serologic biomarkers in the diagnosis of PCP. Serum levels of BG, KL-6, […]

The 13th International Workshops on Opportunistic Protists (IWOP13)

The 13th International Workshops on Opportunistic Protists (IWOP-13) was held November 13-15, 2014 in Seville, Spain. The objectives of the IWOP meetings are to: (1) serve as a forum for exchange of new information among active researchers concerning the basic biology, molecular genetics, immunology, biochemistry, pathogenesis, drug development, therapy, and epidemiology of these immunodeficiency-associated pathogenic eukaryotic microorganisms that are seen in patients with AIDS and; (2) to foster the entry of new and young investigators into these underserved research areas.

Microsporidia as emerging pathogens and the implication for public health: a 10-year study on HIV-positive and -negative patients.

Despite recent advances in the understanding and diagnosis of emerging microsporidian pathogens, more research is necessary to elucidate their complex epidemiology. In fact, studies that reflect true human-infecting microsporidian prevalence are still inadequate. The present 10-year study was undertaken to examine the occurrence of Microsporidia in 1989 stools, 69 urine and 200 pulmonary specimens from HIV-positive and HIV-negative patients using PCR and DNA sequencing.

Pneumocystis jirovecii pneumonia: still a concern in patients with haematological malignancies and stem cell transplant recipients

Pneumocystis jirovecii can cause life-threatening pneumonia following treatment for haematological malignancies or after HSCT. The mortality rate of P. jirovecii pneumonia (PCP) in these patients is 30%-60%, especially after HSCT. The clinical presentation of PCP in haematology differs from that associated with HIV infection, with the disease being acute and more often severe, having a lower fungal burden and being more frequently linked to treatment with corticosteroids.
