Abstract

Introduction: 

Since the dawn of the new millennium, Candida species have been increasingly implicated as a cause of both healthcare-associated as well as opportunistic yeast infections, due to the widespread use of indwelling medical devices, total parenteral nutrition, systemic corticosteroids, cytotoxic chemotherapy, and broad-spectrum antibiotics. Candida tropicalis is a pathogenic Candida species associated with considerable morbidity, mortality, and drug resistance issues on a global scale.

Methodology: 

We report a case of a 43-year-old man who was admitted to our hospital for further management of severe coronavirus disease 2019 (COVID-19) pneumonia. During his stay in the ward, he received systemic corticosteroids for a total duration of 32 days. A broad-spectrum antibiotic (piperacillin-tazobactam) was also given due to copious amounts of tracheostomy secretions.

Results: 

The patient’s fever recurred following an afebrile interval of 11 days, and C. tropicalis was cultured from his blood. The yeast was highly resistant to fluconazole and voriconazole but remained susceptible to echinocandins. Unfortunately, the patient was unable to receive any echinocandin and eventually succumbed to candidemia.

Conclusions: 

Multilocus sequence typing was used to characterize C. tropicalis as a novel diploid sequence type (i.e., 1515) that has not been previously reported.

#USA, Novel #Influenza A #H5N1 Virus: One Pediatric Case in #California {FluView}

By G.M.
 {Excerpt} One confirmed human infection with influenza A(H5) virus was reported to CDC this week. To date, human-to-human transmission of influenza A(H5) virus has not been identified in the United States. This case was reported by the California Department of Public Health and occurred in a child less than 18 years old with no known contact with influenza A(H5N1) virus-infected animals or humans . The investigation into the source of infection for this case is ongoing , and no human-to-human transmission has been identified. A specimen from the individual was tested at a public health laboratory using the CDC influenza A(H5) assay before being sent to CDC for further testing. The specimen was positive for influenza A(H5) virus using diagnostic RT-PCR at CDC. Additional analysis including genetic sequencing is underway. In response to this detection, additional case investigation and contact monitoring are being conducted by public health officials in California. There have now be...

#USA, Two more #human cases of #H5N1 #birdflu reported in #California

By G.M.
Two cases of bird flu have been reported in San Joaquin County, California, local health officials said. According to a press release issued Friday and reported by the Sacramento Bee , health officials with San Joaquin County Public Health Services said both cases were farm workers who were exposed to infected animals . Both people are showing mild symptoms and are recovering, officials said, adding that there are 34 total confirmed cases across California. In a warning posted on Facebook, health officials said bird flu was “spreading in several farms such as poultry and cattle” and urged residents to take precautions to prevent the spread of the disease. Precautions include the use of protective equipment when handling poultry, dairy cattle or other animals that may be infected, and when handling raw and unpasteurized milk. (...) There are currently 60 confirmed cases of bird flu in the country . While most of the cases are in California , other states with confirmed cases include Col...

#PuertoRico - High pathogenicity avian #influenza #H5N1 viruses (#poultry) (Inf. with) - Immediate notification

By G.M.
Highly pathogenic avian influenza (HPAI) H5N1 clade 2.3.4.4b was confirmed on one poultry premises in Culebra Municipality, Puerto Rico . This is the first confirmed case of HPAI in poultry from Puerto Rico. Full genotyping confirms the virus as a reassortant of the A3 genotype with North American wild bird lineage viruses ( AM PB2, PA, NP ). Comparisons of the virus to other recent detections from wild birds and North America reports are in progress. The USDA Animal and Plant Health Inspection Service (APHIS), in conjunction with State Animal Health and Wildlife Officials, are conducting comprehensive epidemiological investigations and enhanced surveillance in response to the HPAI H5N1 related events.
