Apparent tick paralysis by Otobius megnini in a cat.

In this study, we report a rare case of tick paralysis in a cat induced by Otobius megnini infestation. An 11-month-old female cat was admitted to a private veterinary clinic in Luling Texas, USA presenting with depression, tachycardia, and flaccid paralysis of the entire body. The four recovered ticks were morphologically and molecularly identified as O. megnini nymphs. Following initial tick removal and treatment with 0.1% milbemycin oxime in the ear canal on the first day of hospitalization, and additional tick removal and topical selamectin treatment on the second day of hospitalization the animal gradually improved. The recovery of the cat after tick removal supports the diagnosis of tick toxicosis. While tick antiserum is not available in North America, prevention of tick infestation and tick-induced paralysis can be effectively accomplished using repellent collars and the compliant use of other ectoparasiticide products year-round.

Antimicrobial Effects of Plant-Based Supplements on Gut Microbial Diversity in Small Ruminants.

Every year in the United States, approximately 48 million people are affected by bacterial illnesses that are transmitted through food, leading to 3000 fatalities. These illnesses typically stem from food animals and their by-products, which may harbor dangerous pathogens like Salmonella enterica, Listeria monocytogenes, enterohemorrhagic Escherichia coli O157:H7, and Campylobacter jejuni. Factors that contribute to contamination include manure used as a soil amendment, exposure to polluted irrigation water, and contact with animals. To improve food safety, researchers are studying pre-slaughter intervention methods to eliminate bacterial contamination in live animals. While small ruminants are vital to global agriculture and income generation for small farms, traditional feeding practices involve supplements and antibiotics to boost performance, which contributes to antibiotic resistance. Hence, researchers are looking for friendly bacterial strains that enhance both animal and human health without impacting livestock productivity. The global trend is to minimize the use of antibiotics as feed supplements, with many countries prohibiting or limiting their use. The aim of this review is to provide a comprehensive insight on the antioxidant capabilities, therapeutic attributes, and applications of bioactive compounds derived from sweet potato tops (SPTs), rice bran (RB) and radish tops (RTs). This overview provides an insight on plant parts that are abundant in antioxidant and prebiotic effects and could be used as value-added products in animal feed and pharmaceutical applications. This review was based on previous findings that supplementation of basal diets with natural supplements represents a multifaceted intervention that will become highly important over time. By remarkably reducing the burden of foodborne pathogens, they apply to multiple species, are cheap, do not require withdrawal periods, and can be applied at any time in food animal production.
