Miniconference INPOMED

A miniconference presenting final results achieved during INPOMED project was arranged on May 23, 2022 at the Veterinary Research Institute, Brno, Czech Republic. Recordings of all presentations can be seen here.

INPOMED webinar

Dear colleagues,

on March 22, 2022, as a part of Interreg supported INPOMED project we organised an on-line webinar. The first presentation was given by Prof. Bernd Kaspers from Ludwig-Maximilians University Munich and was be focused on the importance of gut microbiota on the development of gut immune system. Second invited presentation was delivered by prof. Silke Rautenschlein from University of Veterinary Medicine Hannover covering a topic of Campylobacter interactions with chicken host. Following invited speaker’s presentations, results of INPOMED project partners were introduced in a form of four brief presentations. We hope that you have learnt at least something new and inspirative for you.

INPOMED project on-line seminar

Dear colleagues,

it is our pleasure to announce that on March 22, 2022, from 1 p.m. to 3 p.m., on-line webinar will be organised. The seminar is part of the Interreg supported INPOMED project „INPOMED – Innovations in Poultry Medicine“. Seminar will start with two presentations by invited speakers. The first presentation will be given by Prof. Bernd Kaspers from Ludwig-Maximilians University Munich and will be focused on the importance of gut microbiota on the development of gut immune system. Second invited presentation will be delivered by prof. Silke Rautenschlein from University of Veterinary Medicine Hannover covering a topic of Campylobacter interactions with chicken host. Following invited speaker’s presentations, results of INPOMED project partners will be introduced in a form of four brief presentations. All presentations will be in English though questions can be raised in English, German or Czech language. We are looking forward to meet you on-line on March 22 at 1 p.m.

Lactobacilli as probiotics for poultry

Lactobacilli are generally accepted as beneficial microbes. Despite this, in our hands, lactobacilli do not permanently colonise chicken intestinal tract and do not protect chickens against Salmonella Enteritidis challenge. We have repeatedly shown that if lactobacilli and Salmonella meet each other for the first time as late as in the chicken crop, lactobacilli administration does not lead to protection of chickens against Salmonella. However, if lactobacilli and Salmonella are simultaneouysly inoculated to chicken feed and conditions are set so that fermentation may proceed, metabolic activity of lactobacilli leads to decrease in pH and suppression of Salmonella viability. The most common and frequent probiotic effect of lactobacilli as probiotics is therefore expressed as fermentation and decrease in pH what results in suppression of other microbiota viability including pathogens like Salmonella. For more details, see HERE.

Influence of lincomycin-spectinomycin treatment on the outcome of Enterococcus cecorum infection and on the cecal microbiota in broilers

Enterococcus cecorum (EC) is one of the main reasons for skeletal disease in meat type chickens. Intervention strategies are still rare and focus mainly on early antibiotic treatment of the disease, although there are no data available concerning the effectivity of this procedure. The present study aimed to investigate the efficacy of early lincomycin-spectinomycin treatment during the first week of life after EC-infection. Furthermore, the impact of lincomycin-spectinomycin treatment and EC infection on the development of cecal microbiota was investigated. For more information, see here.

Ecological adaptations and consequences for selection of novel types of probiotics

In this review we reminded characteristics of chicken gut anaerobes and related them to the probiotic potential of individual gut microbiota members. By comparison of already published data we proposed  that bacterial species from the intestinal tract which exhibit any form of adaptation to aerobic environment (spore forming bacteria, aerotollerant or facultative anaerobes) are less efficient in the colonisation of chicken intestinal tract and are therefore less suitable as probiotics intended for a single dose administration.

Novel probiotic products are tested under field conditions

After extended testing under laboratory conditions and contained environment of experimental animal houses we moved towards verification of probiotic efficacy under real field conditions. Key for the success is the administration of strictly anaerobic cultures. This is why we test different approaches like administration via drinking water, fermented feer or spraying in hatcharies.
