Feeding laying hens with lactobacilli improves internal egg quality and animal health.

Feeding animals with lactobacilli strains is a biotechnological strategy to improve production, food quality, and animal health. Thus, this study aimed to select new lactic acid bacteria (LAB) able to improve laying hens health and egg production. Forty Bovans White layers (two days old) were randomly divided into four experimental groups that receive an oral gavage with saline solution (control group) or with one of the three lactobacilli selected (KEG3, TBB10, and KMG127) by their antagonistic activity against the foodborne pathogen Bacillus cereus GGD_EGG01.

Contaminated water confirmed as source of infection by bioassay in an outbreak of toxoplasmosis in South Brazil.

The protozoan Toxoplasma gondii is a causative agent of toxoplasmosis, an important and widespread zoonotic disease. The transmission of this disease in humans includes ingestion of sporulated oocysts present in contaminated water or food. T.

Combination of Adt-O1Manisa and Ad5-boIFNλ3 induces early protective immunity against foot-and-mouth disease in cattle.

Foot-and-mouth-disease (FMD) remains the most infectious livestock disease worldwide. Although commercially available inactivated or adenovirus-vectored-vaccines (Ad5-FMD) are effective, they require 5-7 days to induce protection. Therefore, new control strategies that stimulate rapid immune responses are needed.

Evaluation of a Fiber-Modified Adenovirus Vector Vaccine against Foot-and-Mouth Disease in Cattle.

Novel vaccination approaches against foot-and-mouth disease (FMD) include the use of replication-defective human adenovirus type 5 (Ad5) vectors that contain the capsid-encoding regions of FMD virus (FMDV). Ad5 containing serotype A24 capsid sequences (Ad5.A24) has proved to be effective as a vaccine against FMD in livestock species.

Type III interferon protects swine against foot-and-mouth disease.

In recent years, we have developed novel strategies to control foot-and-mouth disease (FMD), including the use of biotherapeutics such as interferons (IFN) delivered by a replication-defective human adenovirus type 5 (Ad5). Swine can be sterilely protected after vaccination with an Ad5 that encodes porcine type I IFN (poIFN-α), and cattle can be similarly protected or develop significantly reduced disease when treated with an Ad5 delivering bovine type III IFN (boIFN-λ3). Here, we have evaluated the efficacy of porcine IFN-λ3 (poIFN-λ3) against FMD virus in vivo.
