The role of lysogeny in the modification of phage typing patterns of Staphylococcus aureus isolated from dairy cows

, 1980
Strains of Staphylococcus aureus were isolated at a single sampling from cows in a dairy herd. When typed by phage most showed a complex pattern of lysis with group III and IV phages.

An Adenoviral‐Vectored Tp0326 Vaccine Elicits Robust Functional Antibodies to Prevent Treponema pallidum Dissemination in a Rabbit Model

Advanced Science, EarlyView.
Vaccination promotes cellular infiltration into primary lesions and effectively inhibits T. pallidum dissemination to distal organs. Notably, transfer of lesion tissue from immunized animals fails to establish infection in naive recipients, confirming specific protective immunity.

Site‐Specific Protein Bioconjugation Through Cellular Incorporation of Noncanonical Amino Acids

Angewandte Chemie, EarlyView.
Genetic code expansion (GCE) enables site‐specific installation of noncanonical amino acids containing bioorthogonal conjugation handles, allowing precise, homogeneous protein modification. This review examines the principles of orthogonal translation, surveys the chemistries available for chemoselective labeling, and highlights emerging multi‐site ...

New phage typing scheme for Vibrio cholerae O1 biotype El Tor strains

, 1993
The conventional phage typing scheme proposed by S. Basu and S. Mukerjee (Experientia 24:299-300, 1968) has been used routinely for identification of the strains at the Vibrio Phage Reference Laboratory since 1968. However, because of limitations of this

Determination of Gene‐Level Fitness Contributions Across the Mucin‐Utilization Network of Bacteroides thetaiotaomicron

Advanced Science, EarlyView.
Genome‐wide CRISPRi and RNA‐seq resolve how B. thetaiotaomicron converts host mucosal glycans into fitness. The study reveals a layered mucin‐utilization architecture in which capsular polysaccharides constrain surface access, extracellular CAZymes and peptidases show functional redundancy, and intracellular catabolic pathways create discrete metabolic

A Dual‐Delivery System Designed to Overcome EV‐Mediated Ferroptosis Resistance for Efficient Solid Tumor Therapy

Advanced Science, EarlyView.
(A) Establishment and characterization of the osteosarcoma‐targeted dual‐delivery nanoplatform mBAP1/siENO1@LNP‐OTP for simultaneous regulation of BAP1 and ENO1 in tumor cells. (B) After intravenous administration, mBAP1/siENO1@LNP‐OTP preferentially accumulates at tumor sites through OTP‐mediated targeting.

In Vitro Selection of Functional Neoproteins Containing Highly Fluorinated Cores

Angewandte Chemie, EarlyView.
The generation of neoproteins—functional proteins containing unnatural amino acids—is a key goal in synthetic biology. We develop a platform to discover neoproteins with specified bioactivity from trillion‐member sequence libraries, using genetic code reprogramming, in vitro selection and microwave peptide synthesis.

A Chiral Virus‐Like Nanoplatform That Broadly Mediates Antibiotic Delivery to the Brain for Bacterial Meningitis Therapy

Advanced Science, EarlyView.
Chiral virus‐mimicking mesoporous silica nanostructures (CVSNs) efficiently transport diverse antibiotics across the blood–brain barrier (BBB) into brain parenchyma and cerebrospinal fluid. By enhancing delivery to microglia and astrocytes, CVSNs improve antibiotic bioavailability and therapeutic efficacy against both Gram‐negative and Gram‐positive ...
