Effects of L. reuteri NBF 2 DSM 32264 Consumption on the Body Weight, Body Condition Score, Fecal Parameters, and Intestinal Microbiota of Healthy Persian Cats.

In the literature, there are several studies showing the effects of different probiotic administrations in dogs, while there is limited information about their effects in cats. Furthermore, there are no studies that examined the effects of the probiotic strain Lactobacillus reuteri on cats' welfare, especially considering a specific breed. In this study, the effects of L. reuteri NBF 2 DSM 32264 on body weight, body condition score (BCS), and fecal parameters (fecal score and fecal moisture) of healthy Persian cats were assessed; additionally, a microbiological analysis was carried out to quantify bacterial species like Escherichia coli (for the total coliform count) and Lactobacilli. The administration of L. reuteri NBF 2 DSM 32264 showed no alteration in the body weight and body condition score of Persian cats. The fecal moisture decreased at the end of the study and the values of fecal score were improved. Moreover, at the end of the study period, an increase in Lactobacilli (p > 0.001) was observed. The data collected report the ability of L. reuteri NBF 2 DSM 32264 to improve fecal quality parameters in healthy adult Persian cats, leading to an increase in Lactobacilli and a reduction in total coliforms.

Effects of Feeding a Hypoallergenic Diet with a Nutraceutical on Fecal Dysbiosis Index and Clinical Manifestations of Canine Atopic Dermatitis.

BACKGROUND: an imbalance of the intestinal microbiota can cause health problems in the gastrointestinal tract and in other organs. Canine Atopic Dermatitis (CAD) is a genetically predisposed, inflammatory and pruritic allergic skin disease with multifactorial etiology and multimodal treatment. The aim of this study was to assess the effect of a nutraceutical product on Dysbiotic Index (DI) and the skin lesions of atopic dogs. METHODS: a nutraceutical product was administered to 32 dogs with CAD. The product was associated with a standardized hypoallergenic diet for 60 days; the dietary regimen continued for 120 days, while ongoing therapies remained unchanged. Values of Visual Analogic Scale (VAS), Canine Atopic Dermatitis Lesional Index (CADLI) and DI were evaluated on day 0, 60, 120. RESULTS: all the 32 dogs showed a statistically significant decrease (p < 0.001) to V60 of VAS and CADLI, which persisted and increased to V120 when diet alone was continued. The decrease in the DI value was also statistically significant (p < 0.001). CONCLUSION: the intake of nutraceutical associated with diet resulted in a decrease in the index of intestinal dysbiosis, with an improvement in the subjective severity of cutaneous lesions.
