An oral Vibrio vaccine for salmonids was developed.
The vaccine was produced by spray coating lyophilized
formalin-killed whole cells of Vibrio anguillarum (VA LS 1-
74) onto non-pareil sugar beads. Then methacrylic acrylic
acid copolymer (Eudragit L-30D) was applied as an enteric
protective coating.
Using x-ray radiographic techniques, it was...
At present all vaccines for fish are primarily delivered either by injection or immersion which introduces added stress and labor. A more attractive method of vaccine delivery is oral administration using an enteric protection system, Enteric Coated Antigen Microspheres (ECAMs), which can be utilized for a variety of antigenic forms....
The Bureau of Land Management (BLM) maintains a growing number of feral horses on public rangelands. With population growth rates as high as 22% annually, herds are exceeding their carrying capacity and millions of dollars are spent maintaining captured horses in holding facilities awaiting adoption. To manage the feral horse...
Currently, the only anthrax vaccine licensed for human use in the United States is the Anthrax-vaccine-absorbed (AVA or Biothrax®). AVA suffers from several drawbacks, including a complicated and lengthy dosing schedule that requires six initial injections administered over eighteen months, followed by annual boosters. Therefore, a new generation anthrax vaccine...
Neisseria gonorrhoeae is the sexually transmitted pathogen responsible for millions of cases of gonorrhea worldwide each year. Rapidly-spreading antibiotic resistance is diminishing the ability to effectively treat a disease with significant consequences to female and male reproductive health, as well as to neonatal well-being. A protective vaccine has the potential...
Several systems were examined for the production and delivery of recombinant vaccines for fish. C. crescentus was employed to produce a fragment of the IHNV glycoprotein. When administered by injection to 0.5 gram rainbow trout (Oncorhynchus mykiss), one of the fusion proteins (184 amino acids of the IHNV glycoprotein fused...
In the face of limited resources, how should those resources be allocated? The COVID-19 pandemic highlighted the difficulty of allocating a limited number of vaccines. The Centers for Disease Control and Prevention (CDC) issued standard guidelines based on ethical principles, yet all 50 states in the United States (US) interpreted...
Members of the family Chlamydiae cause a wide range of diseases. Chlamydia trachomatis and C. pneumoniae are most commonly associated with human disease. C. psittaci and C. pecorum are largely animal pathogens, although C. psittaci can cause pneumonia in the elderly and immunocompromised. A vaccine against these pathogens is desirable,...
Expanding efforts to develop preventive gonorrhea vaccines is critical because of the dire possibility of untreatable gonococcal infections. Reverse vaccinology, which includes genome and proteome mining, has proven very successful in the discovery of vaccine candidates against many pathogenic bacteria. However, progress with this approach for a gonorrhea vaccine remains...
