Dear dr. Wijaya Saputra
Seemingly the ELISA titers are not a vaccine titers, because the ts-11 vaccine titers are never ever rise up to this level in 4 weeks period, they diminish or disappear in 4 weeks period. So these titers are infection.
So you have to give antibiotics, preferably after sensitivity test for the MG if possible, otherwise, give blindly a reputable anti-mycoplasmal one.

Newcastle disease (ND) is caused by virulent strains of the Newcastle disease virus (NDV), also recently designated as the Avian Orthoavulavirus 1 (AOAV-1).It is one of the most devastating disease of poultry and wild birds. Phylogenetic analyses clearly distinguish historical isolates (obtained prior to 1960) from currently circulating viruses of class II genotypes V, VI, VII, and XII to XVIII.Ge ...

Indirect ELISA aims to detect antibodies, using plates coated with the antigen.
This is an "indirect" way to diagnostic and occurred disease (contact of body with micro pathogens induced immune response, so we look after antibodies subsequently)
Other ELISA remain available though in the poultry secotr, such as blocking ELISA for Avian Flu or Avian Metapneumovirus

Thank you for the clarification, probably there was a misunderstanding since from what I know, there were some efforts from a company to develop a killed vaccine, which was by the way included in the list you mentioned.The results also you shared regarding anticoccidials effectiveness are very meaningful.Kind regards.

SandySome thoughts on this. Yes birds require a higher bacterial load to get infected as they become aged. One probable reason is salmonella infection in birds will induce a tolerance- development of T-regulatory cells. This might be one reason why they require a higher bacterial load. Our lab conducts research in avian immunology- including pathogens such as coccidia and salmonella. Please keep i ...

Paul Wagura Tilmicosin is a bacteriostatic, that means it stops only multiplication, that's why we talk more about reducing clinical signs and lesions rather than killing the Mycoplasma. There will be always carriers since Mycoplasma infects and do multiplication in organs less or poorly vascularised, and where only few antibiotics target.

MG infection is very common in many countries. Most of the PS & Com. flocks of Pakistan found positive in lab and also showing signs of infection in the field. Negative flocks are getting infection easily from contaminated field.Keeping this in view, I personally feel that sue of vaccines either killed or live is useless. Tilmycosin, the latest antimycoplasma drug is giving better results to r ...

Good day,
I have a question about your slide mentioning vaccines and technologies.
Don't you think that there was some efforts, regardless commercialization, to improve coccidiosis prevention in broilers, either by using specific devices to improve the vaccination process or to add underestimated strains, such as mitis or praecox?
Also, can you give us more details when you mentioned that there i ...

Sachin Patil The F-vax in the United States has changed over the years and now is very non-reactive compared to the past. in 2000, 1/4 of a dose of F-vax by water or spray would result in respiratory signs and 100% seroconversion. In 2010, a full dose of F-vax by spray produced no respiratory reaction and 30 to 40% positive seroconversion. Our producers now have gone to the eyedrop method of appli ...
