Cross-immunity in Nile tilapia vaccinated with Streptococcus agalactiae and Streptococcus iniae vaccines

Publication date: Available online 10 December 2019Source: Fish &Shellfish ImmunologyAuthor(s): Qishuo Wang, Tianzeng Fu, Xincang Li, Qian Luo, Jinjing Huang, Yongcan Sun, Xuepeng WangAbstractStreptococcus agalactiae and Streptococcus iniae are major bacterial pathogens of tilapia that can cause high mortality concomitant with large economic losses to aquaculture. Although development of vaccines using formalin-killed bacteria to control these diseases has been attempted, the mechanism of immunity against streptococcal infections and the cross-protective ability of these two bacteria remains unclear. To explore the immunological role of these vaccines, we compared the immune responses of tilapia after immunization with both vaccines and compared the relative percent survival (RPS) and cross-immunization protection of tilapia after separate infection with S. agalactiae and S. iniae. All results revealed that vaccinated fish had significantly higher (P

Authors: Lizardo K, Ayyappan JP, Ganapathi U, Dutra WO, Qiu Y, Weiss LM, Nagajyothi JF Abstract Chagas disease is caused by Trypanosoma cruzi which is endemic in Latin America. T. cruzi infection results in a latent infection with approximately a third of latently infected patients developing chronic Chagas cardiomyopathy (CCM). CCM is a common cause of cardiomyopathy in endemic regions and has a poor prognosis compared to other cardiomyopathies. The factors responsible for the transition from the asymptomatic indeterminate latent stage of infection to CCM are poorly understood. Our previous studies demonstrated th...

It is interesting, but not compelling if its role...

(Natural News) If you’re under the age of 18 and your parents won’t let you get vaccinated, then they must hate you and want you to die. This is what WikiHow is telling children, anyway, in a new “learn how to do anything” information page that teaches young ones how to secretly get vaccinated without...

Kunkel, Kazuhiro TatedaAbstractPneumococcal conjugate vaccination (PCV) may prevent influenza-related pneumonia, including Streptococcus pneumoniae pneumonia. To investigate PCV efficacy against secondary pneumococcal pneumonia following influenza, PCV was administered intramuscularly 2 and 5 weeks before S. pneumoniae serotype-3 colonization of murine nasopharynges followed by intranasal challenge ...

The surface antigens of apicomplexan parasites function as attachment and invasion in host-parasite interaction. Meanwhile, host immune response is triggered as a result of parasitic invasion. Immunogenicity and potency as a vaccinal candidate antigen of E. tenella surface antigen 4 (EtSAG4) have been unknown. Therefore, a...
