Fusarium is an emerging human opportunistic pathogen of growing importance, especially among immunosuppressed haematology patients due to an increased incidence of disseminated infections over the past two decades. This trend is expected only to continue due to the advances in medical and surgical technologies that will prolong the lives of the severely ill, making these patients susceptible to rare opportunistic infections. Production of mycotoxins, enzymes such as proteases, angio-invasive property and an intrinsically resistant nature, makes this genus very difficult to treat...

Heart transplantation is offered to children with heart failure that is not amenable to medical or surgical therapy. Indications for heart transplant include unrepairable congenital heart disease, failed palliation of congenital heart disease, and cardiomyopathies. There has been tremendous progress in this field since the first heart transplant was performed in 1967. Each year, approximately 500 pediatric heart transplants take place worldwide. Pediatric heart transplant survivors are living longer with their initial transplant...

BACKGROUND: Transplant recipients are at risk of developing progressive multifocal leukoencephalopathy (PML), an opportunistic infection due to reactivation of JC virus. Post-transplant lymphoproliferative disorders (PTLDs) represent a common malignancy in this population, and antiCD20-therapy has become an established component of its treatment. CASE PRESENTATION: We describe the first case of a renal allograft transplant recipient with PTLD who received rituximab-based immune-chemotherapy and developed PML shortly thereafter...

The authors describe pathological and microbiological features of mortalities in a captive breeding colony of Lord Howe Island stick insects ( Dryococelus australis) over a period of 18 months. There were 2 peaks of mortality in this period. In the first, insects presented dead with minimal premonitory signs of illness. In the second, affected insects were ataxic with contracted limbs and inability to climb or right themselves. Gross lesions were uncommon but included pigmented plaques on the gut and cloacal prolapse...

Microorganisms provide both beneficial and harmful effects to human beings. Beneficial effects come from the symbiotic relationship that exists between humans and microbiota, but then several human illnesses have turned some friendly microbes into opportunistic pathogens, causing several microbial-related diseases. Various efforts have been made to create and utilize antimicrobial agents in the treatment and prevention of these infections, but such efforts have been hampered by the emergence of antimicrobial resistance...

Hepatitis C virus (HCV) is a common opportunistic pathogen especially among Human immunodeficiency virus (HIV) infected patients. Due to incongruous studies, the pathological effect of HCV on HIV induced disease are still not fully understood. While some studies have showed no effect of HCV on HIV infection, others reported a defined role of HCV in aggravating the rates of AIDS-related illnesses and mortality. The explanation of such variances may be due to the host immune response, viral genotypes, sub-type and quasi-species distribution...

Human immunodeficiency virus (HIV) enters the brain early after infecting humans and may remain in the central nervous system despite successful antiretroviral treatment. Many neuroimaging techniques were used to study HIV+ patients with or without opportunistic infections. These techniques assessed abnormalities in brain structures (using computed tomography, structural magnetic resonance imaging (MRI), diffusion MRI) and function (using functional MRI at rest or during a task, and perfusion MRI with or without a contrast agent)...

Microsporidia are intracellular organisms most commonly known to cause opportunistic infection in patients with human immunodeficiency virus (HIV). There have been several case reports of infection in solid organ and bone marrow transplant recipients. Here, we report a case of a non-HIV-infected renal transplant patient with microsporidiosis of the renal tract associated with acute graft dysfunction. We also review the literature of twelve previously reported cases of microsporidiosis in patients with renal transplants who had described graft involvement...

Thrombocytopenia is one of the most common hematological manifestations seen in HIV patients with approximately 40% of the patients developing thrombocytopenia during their course of illness. Opportunistic infection like tuberculosis is a rare but curative cause of thrombocytopenia in these patients. Clinically, it is a challenge to determine the exact cause and decide the treatment of thrombocytopenia in these patients as both infections can lead to significant thrombocytopenia by varied mechanisms. The treatment options are limited by drug antitubercular treatment highly active antiretroviral therapy (ATT and HAART)-induced thrombocytopenia...

Background: Despite the shift in antiretroviral therapy (ARVs) eligibility cascade from CD4 ≤ 200 to CD4 ≤ 350 to CD4 ≤ 500 mm3 , HIV related morbidity and mortality continue to escalate annually, as do HIV infections. The new paradigm of treatment for all HIV positives individual irrespective of CD4 count may significantly reduce HIV and related illnesses. The author assumes that all HIV infected partners should be eligible for HIV treatment and care, irrespective of CD4 count...

Mucormycosis, a rare opportunistic infection seen in immunocompromised hosts, is caused by fungi of Mucorales family. It may be confined to the organs, such as rhinocerebral and pulmonary mucormycosis, or may cause disseminated infection. A 14-year-old boy presented to our clinic with fever and left upper quadrant abdominal pain, and on evaluation was found to have pancytopaenia, and imaging revealed ill-defined splenic collection with thrombus in the splenic vein. He was started on empirical intravenous antibiotics, followed by antifungals empirically as he did not show any improvement clinically...

Proteus mirabilis, a Gram-negative bacterium, is ubiquitous in the environment and is considered as the normal microflora in the human gastrointestinal tract. However, this bacterium is an opportunistic pathogen in humans, often causing urinary tract infections. Moreover, Proteus has been frequently isolated from food animals, including poultry. Whether this bacterium contributes to the foodborne illness in humans is unclear. In this report, P. mirabilis isolates recovered from broilers during housing in the units were characterized, their antimicrobial activity was assayed, and broiler immune response to the soluble proteins was determined...

BACKGROUND: Criteria for the 2007 WHO algorithm for diagnosing tuberculosis among HIV-infected seriously ill patients are the presence of one or more danger signs (respiratory rate > 30/min, heart rate > 120/min, temperature > 39 °C, and being unable to walk unaided) and cough ≥ 14 days. Determining predictors of poor outcomes among HIV-infected inpatients presenting with WHO danger signs could result in improved treatment and diagnostic algorithms. METHODS: We conducted a prospective cohort study of inpatients presenting with any duration of cough and WHO danger signs to two regional hospitals in Cape Town, South Africa...

REVIEW
Rebekah M Martin, Michael A Bachman
Klebsiella pneumoniae is a Gram-negative pathogen that has a large accessory genome of plasmids and chromosomal gene loci. This accessory genome divides K. pneumoniae strains into opportunistic, hypervirulent, and multidrug-resistant groups and separates K. pneumoniae from two closely related species, Klebsiella variicola and Klebsiella quasipneumoniae . Some strains of K. pneumoniae act as opportunistic pathogens, infecting critically ill and immunocompromised patients. These K. pneumoniae are a common cause of health-care associated infections including pneumonia, urinary tract infections (UTIs), and bloodstream infections...

While bereavement camps serve as a support for children, this study examines a therapeutic recreation-based camp for families who have lost a child. The study triangulated documents, researcher reflection, and staff interviews to highlight the themes of Searching & Finding, Getting to Know, Finding the Balance, and Joining. Developing opportunistically through internal and external factors, the camp's evolution represents a closing of the loop, from supporting families of living children to also supporting the families of children who have died...

HIV-associated neurocognitive disorders (HAND) remain frequent even among individuals receiving combined antiretroviral therapy (cART). In addition, HAND may adversely affect the quality of life and adherence to cART. There is scarce epidemiological information about HAND in Latin America. This cross-sectional study recruited HIV-infected patients from a tertiary teaching institution in São Paulo, Brazil, between May 2013 and February 2015. The patients were adults with at least 4 years of education and patients with current neurological or psychiatric diseases were excluded...
