Mitigating Salmonella In Poultry Using Probiotics: Mechanisms, Challenges, And Opportunities, Oluwaseun D. Adeyemi, Samuel N. Nahashon

Food and Animal Sciences Faculty Research

The global poultry industry continues to face significant challenges due to Salmonella infections, which pose severe public health concerns and economic losses. Recently, the reemergence of antimicrobial resistance has led to the restriction of antibiotic use in poultry, especially as growth promoters, thus accelerating the search for sustainable alternatives. Among these, probiotics have gained attention as potential candidates for improving poultry health and mitigating Salmonella colonization in the gut. This review summarizes the key mechanisms through which probiotics exert anti-Salmonella effects, including competitive exclusion, production of antimicrobial substances, reinforcement of the intestinal barrier, and modulation of host immune responses.

Effect Of Heat Stress On Jejunal Epithelial Barrier Integrity In Broilers Divergently Selected For High- And Low-Water Efficiency, Elizabeth S. Greene, Sara Orlowski, Sami Dridi

Poultry Science Faculty Publications and Presentations

Drought and water scarcity, exacerbated by global warming, are enormous threats to global food sustainability and security. Poultry, in particular, are highly impacted by adverse environmental stressors. As nutrient absorption and intestinal integrity are critical for growth and performance, understanding the impact on the broiler gastrointestinal tract is highly relevant. Here, we examined the effect of chronic cyclic heat stress (HS) on the jejunal expression profile of tight-junction, gap-junction, adherens, and desmosome genes in the 4th generation of broiler lines divergently selected for low (LWE)- and high-water efficiency (HWE). Male HWE and LWE broilers (n = 240/line) were allotted to …

A Bovine Cell Line Resistant To Japanese Encephalitis Virus Entry But Permissive To Post-Entry Replication, Sang-Im Yun, Young-Min Lee

Animal, Dairy, and Veterinary Science Faculty Publications

Japanese encephalitis virus (JEV) is a mosquito-borne zoonotic orthoflavivirus that poses a significant global health threat. It causes severe neuroinflammatory disease in humans and reproductive failure in swine. Because of the broad host range and cell tropism of JEV, identifying animal cell lines resistant to infection has been a persistent challenge. In this study, we demonstrate that Madin–Darby bovine kidney (MDBK) cells are resistant to JEV infection yet remain fully permissive to viral replication when transfected with viral genomic RNA. Using immunoblotting, immunofluorescence, and flow cytometry, we show that MDBK cells, unlike the highly susceptible baby hamster kidney (BHK-21) cells …

Association Of Hair Shedding Level With Cow–Calf Performance In Summer-Bred Dexter Cattle, Ichard Browning Jr, Emily G. Hayes, Kaylee S. Hillin, Maria Lenira Leite-Browning

Food and Animal Sciences Faculty Research

Reduced winter hair shedding in beef cows through the spring and summer months may contribute to heat stress and reduced performance in spring-calving herds. This study evaluated the relationship of hair shedding with the fertility and maternal performance of 72 Dexter cows. Hair shedding data for 20 May, 3 June, 17 June, and 1 July in 2019 were used to classify cows as high or low hair shedders. Hair shedding levels were lower (p < 0.05) for 2-year-old cows than for cows 7+ years of age for the first three dates and lower (p ≤ 0.05) for lactating cows than for dry cows on the first two dates. Concurrent and four years of historical performance records were used to assess the associations between hair shedding and cow–calf performance. Data from 230 natural matings in July and August from 2015 to 2019 were analyzed. Birth to weaning weight data were recorded from 2016 to 2019 on 124 spring-born calves. Cow fertility was higher (p < 0.05) for high-shed cows than for low-shed cows for the 1 July classification. When the records from cows that were dry in 2019 were excluded from testing, fertility was higher (p < 0.05) for high-shed cows than for low-shed cows at all four scoring dates. The associations of cow hair shedding levels with preweaning calf performance were minimal. Dexter cows exhibiting higher hair shedding levels in the spring and summer expressed higher summer fertility.

Turkish Journal of Zoology

Eyelids play a crucial role in protecting the eyes of vertebrates; however, certain  reptile species, such as Ophisops elegans, completely lack movable eyelids. In this  study, we present the first video-documented evidence of a blink-like reflex in O.  elegans, captured through endoscopic field observations and corroborated by laboratory video analysis. The observed movement consisted of a brief convex  deformation of the ocular surface, lasting approximately 0.3 s and resembling a blink  despite the presence of a fixed transparent brille. This behavior was observed once in  the field and twice under controlled laboratory conditions. We propose that O.  elegans may employ …

Habitat Diversity Or Altitudinal Gradient? Which Factor Better Explains Ground Beetle (Coleoptera: Carabidae) Biodiversity? A Case Study From Davraz Mountain (Isparta, Türkiye), Ebru Ceren Fi̇dan, Ali̇ Gök

Turkish Journal of Zoology

Ground beetle (Carabidae) species diversity and spatial distribution were surveyed  across five habitat types along an elevational gradient on Davraz Mountain, a  biogeographical transition area in southwestern Türkiye. The analyses showed that  habitat heterogeneity—particularly soil moisture and texture—exerts a stronger  influence on carabid diversity than elevation. Sørensen’s and Jaccard similarity  indices showed strong faunal overlap between some sampling areas, while  multivariate principal components and canonical correspondence analyses verified  distinct environmental gradients influencing community structure. Diversity indices  indicated varying levels of species richness and evenness across sampling areas.  The data highlight the importance of fine-scaled habitat features in driving ground  beetle …

This study investigates the impact of winter nighttime versus daytime milking on melatonin concentration in milk and explores its relationship with somatic cell count (SCC) and differential somatic cell count (DSCC). Milk samples were collected from 40 Holstein cows at 12-hour intervals (04:00 AM Night samples and 04:00 PM Day samples) during the winter season (11 h of light and 13 h of darkness). The relationship between melatonin content, SCC and DSCC was assessed. Night milk had significantly higher melatonin levels (15.63 ± 1.90 pg/mL) compared to day milk (6.80 ± 0.75 pg/mL). SCC was significantly lower in night milk …
