“…This study suggested that overall prevalence of ectoparasites of dairy cows was 69%. This finding was higher than the reports of Urge B [20], who reported 40.76% prevalence of ectoparasites. This difference might be due to the presence of various factors like veterinary service delivery system, feeding and management, animal husbandry practice, and variation in the geographical locations.…”

Cattle in Sudan serves multiple purposes in agricultural systems, and producing milk is crucial for raising income and providing for domestic needs. However, there is no historical data on the assessment of cattle welfare in Sudan, especially in Nyala. The current study was carried out on 11 dairy farms with Frisian cows from January to March 2021. The primary goal of the study was to assess dairy cows' welfare issues. In this study, 155 female Friesian cows were randomly selected from the farms and examined. Data was collected by closely observing, and the following factors were evaluated: appropriate behaviors, emotional state, physical state, lameness, lesion and injury, health status, and cleanliness of the body. According to the study, the following percentages of animals were impacted: Among cows, 21.3% exhibited anxious behavior, 23.2% displayed fear, 54.2% had thin body conditions, and 27.1% had very thin body conditions. Twenty percent of cows had mildly damaged hocks, 13.5% had swollen knees without skin damage, and 11.6% had swollen knees with skin damage. Cows with dirty udders, dirty hindquarters, dirty lower legs, and dirty flanks comprised 32.3%, 52.3%, 49.7%, and 43.2% of the herd. Additionally, 69.0% of cows had ectoparasites, 28.4% had abnormal nasal discharge, 31.6% had abnormal ocular discharge, and 27.1% had hair loss. We conclude that the major welfare issues highlighted in this study include injuries, ectoparasites, unclean coats, and health status. Education and veterinary services are required to improve the wellbeing of the dairy cattle in the research region.

“…In addition to ticks, other blood-feeding parasites such as lice and fleas have also been implicated as potential vectors for brucellosis. A study conducted in Ethiopia found that lice collected from cattle were positive for Brucella DNA, suggesting their potential role in transmitting the bacteria [ 88 ]. Similarly, a study conducted in Mexico detected Brucella DNA in fleas collected from dogs [ 55 ].…”

Background Brucellosis is a zoonotic affliction instigated by bacteria belonging to the genus Brucella and is characterized by a diverse range of pervasiveness, multiple transmission routes, and serious hazards. It is imperative to amalgamate the current knowledge and identify gaps pertaining to the role of ticks in brucellosis transmission. Methods We systematically searched China National Knowledge Infrastructure (CNKI), WanFang, Google Scholar, and PubMed on the topic published until April 23, 2022. The procedure was performed in accordance with the Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) guidelines. The selected articles were categorized across three major topic areas, and the potential data was extracted to describe evidence-practice gaps by two reviewers. Results The search identified 83 eligible studies for the final analyses. The results highlighted the potential capacity of ticks in brucellosis transmission as evidenced by the detection of Brucella in 16 different tick species. The pooled overall prevalence of Brucella in ticks was 33.87% (range: 0.00–87.80%). The review also revealed the capability of Brucella to circulate in parasitic ticks' different developmental stages, thus posing a potential threat to animal and human health. Empirical evidence from in vitro rodent infection experiments has revealed that ticks possess the capability to transmit Brucella to uninfected animals (range: 45.00–80.00%). Moreover, significant epidemiological associations have been found between the occurrence of brucellosis in animals and tick control in rangelands, which further suggests that ticks may serve as potential vectors for brucellosis transmission in ruminants. Notably, a mere three cases of human brucellosis resulting from potential tick bites were identified in search of global clinical case reports from 1963 to 2019. Conclusions It is imperative to improve the techniques used to identify Brucella in ticks, particularly by developing a novel, efficient, precise approach that can be applied in a field setting. Furthermore, due to the lack of adequate evidence of tick-borne brucellosis, it is essential to integrate various disciplines, including experimental animal science, epidemiology, molecular genetics, and others, to better understand the efficacy of tick-borne brucellosis. By amalgamating multiple disciplines, we can enhance our comprehension and proficiency in tackling tick-borne brucellosis.
