Comparative Analysis of Microbial Communities in Each Developmental Stage of in Two Regions in Inner Mongolia, China.

is the most widely distributed tick genus in China. , a predominant tick species in Inner Mongolia, can carry and transmit pathogenic microorganisms. Here, were collected from Ordos (O-D) and Hinggan League (H-D) in the Inner Mongolia.

Sheep challenged with sheep-derived type II Mycobacterium avium subsp. paratuberculosis: the first experimental model of paratuberculosis in China.

Background: Paratuberculosis (PTB), caused by Mycobacterium avium subsp. paratuberculosis (MAP), is difficult to diagnose in the early stages and poses substantial challenges in prevention, control, treatment, and eradication. A well-defined animal model can help identify disease markers and serve as a platform for vaccine and drug development.

Prevalence and Genotyping of subsp. in Sheep from Inner Mongolia, China.

Background: Paratuberculosis (PTB) is a chronic wasting disease mainly caused by subsp. (MAP) in ruminants. It is difficult to diagnose, prevent, treat, and eradicate, thereby causing serious economic losses to the livestock industry.

Prevalence and genotyping of Enterocytozoon bieneusi in cattle from Shanxi and Inner Mongolia, China.

Enterocytozoon bieneusi is a zoonotic pathogen, with cattle serving as major reservoirs and important mediums for its transmission. However, data on the prevalence and subtypes of E. bieneusi in cattle from Northern Shanxi and Central Inner Mongolia, China, are limited.

The Impact of subsp. on Intestinal Microbial Community Composition and Diversity in Small-Tail Han Sheep.

Paratuberculosis (PTB), primarily caused by subsp. (MAP), is a chronic infection that affects ruminants and is difficult to prevent, diagnose, and treat. Investigating how MAP infections affect the gut microbiota in sheep can aid in the prevention and treatment of ovine PTB.

Comparative analysis of microbial communities in different growth stages of .

Ticks were identified as arthropods that are pathogenic vectors. is one of the dominant tick species in Inner Mongolia, and it carries and transmits a wide range of pathogenic microorganisms. However, at present, only the detection of adult ticks and different developmental stages carrying one specific pathogen, or the next-generation sequencing of adult ticks were available.

Serological investigation and genotyping of Mycobacterium avium subsp. paratuberculosis in sheep and goats in Inner Mongolia, China.

Paratuberculosis a contagious and chronic disease in domestic and wild ruminants, is caused by Mycobacterium avium subspecies paratuberculosis (MAP). Typical clinical signs include intractable diarrhea, progressive emaciation, proliferative enteropathy, and mesenteric lymphadenitis. Paratuberculosis is endemic to many parts of the world and responsible for considerable economic losses.

Comparative analysis of the pathogenic mechanisms of street rabies virus strains with different virulence levels.

Objective: To characterize two strains of street rabies virus (RABV) isolated from the brain tissue of cattle from Inner Mongolia. Differences in the histopathological and ultrastructural changes in the brain tissue of infected mice were determined to reveal variation in the pathogenesis of infection between street rabies virus strains.

Methods: Ten-day-old mice were intracranially inoculated with one of three virus strains and brain tissue harvested when the mice were moribund.

Identification of animal rabies in Inner Mongolia and analysis of the etiologic characteristics.

Objective: To perform pathological observation and etiological identification of specimens collected from dairy cows, beef cattle and dogs which were suspected of rabies in Inner Mongolia in 2011, and analyze their etiological characteristics.

Methods: Pathological observation was conducted on the brain specimens of three infected animals with Hematoxylin-Eosin staining, followed by confirmation using immunofluorescence and nested RT-PCR methods. Finally, phylogenetic analysis was conducted using the virus N gene sequence amplified from three specimens.

[Molecular genetic evolution analysis of new A(H1N1) influenza virus].

In order to analyze the molecular epidemiology of A (H1N1) influenza virus in 2009, the complete genome sequences of influenza strains from different host sources downloaded from the NCBI were analyzed on genetic evolution by DNAstar software in this research. The results showed that 79 mutation sites of new A (H1N1) influenza virus were observed compared to previous human A (H1N1) influenza strain, including 14 mutation sites new in all A (H1N1) influenza sources and 37 mutation sites only observed in swine strain. A significant difference was represented in antigenic sites between new A (H1N1) influenza strain and the previous human A (H1N1) strain.
