Abstract
Epizootic hemorrhagic disease (EHD) is an infectious viral disease caused by epizootic hemorrhagic disease virus (EHDV) and EHDV frequently circulates in wild and domestic ruminants. Sporadic outbreaks of EHD have caused thousands of deaths and stillbirths on cattle farms. However, not much is known about the circulating status of EHDV in Guangdong, southern China. To estimate the seroprevalence of EHDV in Guangdong province, 2886 cattle serum samples were collected from 2013 to 2017 and tested for antibodies against EHDV using a competitive ELISA. The overall seroprevalence of EHDV reached 57.87% and was highest in autumn (75.34%). A subset of positive samples were serotyped by a serum neutralization test, showing that EHDV serotypes 1 and 5-8 were circulating in Guangdong. In addition, EHDV prevalence always peaked in autumn, while eastern Guangdong had the highest EHDV seropositivity over the five-year period, displaying apparent temporal-spatial distribution of EHDV prevalence. A binary logistic model analysis indicated a significant association between cattle with BTV infections and seroprevalence of EHDV (OR = 1.70, p < 0.001). The co-infection of different serotypes of EHDV and BTV raises a high risk of potential genomic reassortment and is likely to pose a significant threat to cattle, thus urging more surveillance to monitor their circulating dynamics in China.

Abstract
PURPOSE Canine hookworm disease is a global zoonotic parasitic disease caused by a variety of nematodes in families Ancylostomatidae, including Ancylostoma spp., Necator spp., and Uncinaria spp., in the small intestine (mainly the duodenum) of dogs. The disease is widely distributed in China. The purpose of this study is to systematically diagnose and treat canine hookworm disease through the case of miniaturization Schnauzer dog feed infected with A. ceylanicum, so as to provide experimental basis for subsequent prevention and control of canine hookworm disease. METHODS In the current study, we isolated hookworm eggs from a diseased miniature schnauzer, then the polymerase chain reaction (PCR) was used to amplify the ITS1-5.8S-ITS2 gene sequence from genomic DNA extracted from hookworms. Phylogenetic analysis based on ITS1-5.8S-ITS2 gene sequence sequences was inferred using MEGA-X. After phylogenetic analysis, etiologic and symptomatic therapies were used to treat the canine hookworm disease. RESULTS The sequencing results showed that the length of the ITS1-5.8S-ITS2 gene sequence was approximately 960 bp, and ITS1 and ITS2 were extracted to analyze similarity with other hookworms to build a phylogenetic tree. After phylogenetic analysis, the results showed that the diseased miniature schnauzer was infected by A. ceylanicum. Using etiologic and symptomatic therapies, the sick dog with an A. ceylanicum infection was also treated for 5 days. CONCLUSIONS To our knowledge, this is the first report of diagnosis and treatment for canine hookworm disease in Guangzhou city. In addition, with the improvement of economic level, the scale of pet dog breeding is also increasing. The diagnostic methods and treatment schemes adopted in this report will help to standardize the prevention and control of canine hookworm disease.

Abstract
To characterize ticks in cattle from Guangdong Province and Guangxi Zhuang Nationality Autonomous Region, Southern China, 783 cattle in four localities were examined. Among them, 232 (29.63%) cattle were positive for tick infection. A total of 503 ticks collected in these cattle were further investigated. Two Rhipicephalus species, namely R. microplus and R. sanguineus, were firstly identified by morphological features. Thereinto, R. microplus is the prevalent species in cattle in southern China, with high prevalent in summer and autumn annually. Mixed infection of R. microplus and R. sanguineus was just found in yellow cattle. To further confirm the morphological identification of these cattle-origin ticks, a phylogeographic analysis inferred from the sequences of the ribosomal internal transcribed spacer-2 (ITS-2) was performed, and R. microplus and R. sanguineus were identified. However, the morphological taxonomy of R. microplus has been challenged in recent years. The mitochondrial cytochrome c oxidase subunit 1 (cox1) marker was then used to provide higher resolution of R. mircoplus complex. The re-constructed cox1 phylogenetic tree further identified these R. mircoplus tick samples as R. microplus Clade A. These findings illustrated the prevalence and characterization of cattle-origin ticks in Southern China for the first time, and provided base-line information for further control of tick and tick-borne disease in these areas.
