Isolation and genome sequencing of five lytic bacteriophages from hospital wastewater in the Philippines.

Here, we report the genome sequences of five bacteriophages isolated from hospital wastewater, including two new species and two candidates for therapeutic application. No virulence, temperate marker and antibiotic resistance genes were found in the genomes of phage vB_VIPECOOM03 and phage vB_VIPKPNUMC01, making them suitable candidate for therapy.

Calcineurin controls hyphal growth, virulence, and drug tolerance of Candida tropicalis.

Candida tropicalis, a species closely related to Candida albicans, is an emerging fungal pathogen associated with high mortality rates of 40 to 70%. Like C. albicans and Candida dubliniensis, C.

Calcineurin is required for pseudohyphal growth, virulence, and drug resistance in Candida lusitaniae.

Candida lusitaniae is an emerging fungal pathogen that infects immunocompromised patients including HIV/AIDS, cancer, and neonatal pediatric patients. Though less prevalent than other Candida species, C. lusitaniae is unique in its ability to develop resistance to amphotericin B.

Convergent Evolution of Calcineurin Pathway Roles in Thermotolerance and Virulence in Candida glabrata.

Candida glabrata is an emerging human fungal pathogen that is frequently drug tolerant, resulting in difficulties in treatment and a higher mortality in immunocompromised patients. The calcium-activated protein phosphatase calcineurin plays critical roles in controlling drug tolerance, hyphal growth, and virulence in diverse fungal pathogens via distinct mechanisms involving survival in serum or growth at host temperature (37° and higher). Here, we comprehensively studied the calcineurin signaling cascade in C.

Calcineurin controls drug tolerance, hyphal growth, and virulence in Candida dubliniensis.

Candida dubliniensis is an emerging pathogenic yeast species closely related to Candida albicans and frequently found colonizing or infecting the oral cavities of HIV/AIDS patients. Drug resistance during C. dubliniensis infection is common and constitutes a significant therapeutic challenge.
