First molecular detection and genetic diversity of Hepatozoon sp. (Apicomplexa) and Brugia sp. (Nematoda) in a crocodile monitor in Nakhon Pathom, Thailand.

The crocodile monitor (Varanus salvator) is the most common monitor lizard in Thailand. Based on habitat and food, they have the potential to transmit zoonoses, with a high possibility of infecting ectoparasites and endoparasites. Diseases that could infect crocodile monitors and be transmitted to other animals, including humans.

First report of Strongylidae nematode from pilot whale () by molecular analysis reveals the cosmopolitan distribution of the taxon.

This study investigates the identification, genetic composition, and placement in the evolutionary tree of a particular nematode species found in a short-finned pilot whale in the Gulf of Thailand. To accomplish this, we utilized various methods, including microscopic observations, molecular techniques, and comparative analyses to better understand the characteristics of this parasite. Initially, we concentrated on studying the 18s rDNA sequence through nested PCR, resulting in a 774-bp product.

Molecular identification and genetic diversity of equine ocular setariasis in Thailand based on the COI, 12S rDNA, and ITS1 regions.

Equine ocular setariasis is mainly caused by Setaria digitata, and the identification of this filarial nematode is based on morphology. However, morphological characterization alone is insufficient for the detection and differentiation of S. digitata from its congeners.

Ehrlichia canis: Molecular characterization and genetic diversity based on the p28 and trp36 genes.

Ehrlichia canis is a common tick-borne intracellular pathogen causing canine monocytic ehrlichiosis (CME) in dogs worldwide. The aims of this study were to investigate the genetic diversity and antigenicity of E. canis based on the p28 and trp36 genes in dogs in Thailand.

Molecular characterization and genetic diversity of and of cattle in Thailand.

and are the most common tick-borne parasites that cause bovine babesiosis which effects livestock production, leading to economic losses in tropical and subtropical areas of the world. The aims of this study were to determine the molecular detection, genetic diversity and antigenicity prediction of based on spherical body protein 2 () gene and based on rhoptry-associated protein 1a () gene in cattle in Thailand. By PCR assay, the molecular detection of and infection revealed levels of 2.

Anaplasma marginale: Molecular discrimination, recombinant expression and characterization of major surface protein 2.

A. marginale's major surface protein 2 (MSP2) is an immunodominant protein that is encoded by a multigene family. Phylogenetic analysis revealed that the msp2 sequence Thailand strain was clustered in third clade, with similarity values between 90.

Molecular genetic diversity and bioinformatic analysis of Leucocytozoon sabrazesi based on the mitochondrial genes cytb, coxI and coxIII and co-infection of Plasmodium spp.

Leucocytozoon sabrazesi is an intracellular haemoprotozoan parasite responsible for leucocytozoonosis, which is transmitted by insect vectors and affects chickens in tropical and subtropical areas in many countries. It causes huge economic losses due to decreased meat and egg production. In the present study, we used nested PCR to determine the genetic diversity of L.

Molecular discrimination and genetic diversity of three common tick-borne pathogens in dogs in Thailand.

There was little information regarding the occurrence of canine vector-borne disease (CVBDs) in shelter dogs in Thailand. This work is the first report regarding a molecular method used to determine the occurrence and genetic diversity of three canine tick-borne pathogens (TBPs) (Hepatozoon canis, Anaplasma platys and Ehrlichia canis) in blood samples from 275 shelter dogs in the north and central areas of Thailand. The PCR results based on the 18S rRNA and 16S rRNA genes showed that 71 (25.

Molecular characterization of Anaplasma marginale based on the msp1a and msp1b genes.

Anaplasma marginale is an intracellular rickettsial bacterium causing anaplasmosis in ruminants. A. marginale is transmitted biologically by ticks and mechanically by blood-sucking vectors.

Molecular detection and genetic diversity of Leucocytozoon sabrazesi in chickens in Thailand.

Leucocytozoon sabrazesi is the intracellular protozoa of leucocytozoonosis, which is transmitted by the insect vectors and affects chickens in most subtropical and tropical regions of the globe, except South America, and causing enormous economic losses due to decreasing meat yield and egg production. In this study, L. sabrazesi gametocytes have been observed in the blood smears, and molecular methods have been used to analyse the occurrence and genetic diversity of L.

Molecular and recombinant characterization of major surface protein 5 from Anaplasma marginale.

Anaplasmosis is a tick-borne disease caused by the intracellular rickettsia Anaplasma marginale, which affects cattle and other ruminants in both tropical and subtropical regions of the world, and also causing tremendous economic losses due to decreasing livestock production. The major surface protein 5 (MSP5) of A. marginale is an immunodominant and highly conserved protein encoding by a single gene.

Molecular detection and genetic diversity of Anaplasma marginale based on the major surface protein genes in Thailand.

Anaplasma marginale is the rickettsial agent of anaplasmosis, a tick-borne disease, which affects cattle and other ruminants in tropical and subtropical areas of the world, and causing huge economic losses because of decreasing meat and milk production. In the present study, molecular methods have been used to determine the occurrence and genetic diversity of A. marginale, based on the genes encoding the major surface proteins (msps) genes, in blood samples from 520 cattle and 121 buffaloes in the north and northeastern regions of Thailand.

Recombinant expression and characterization of major surface protein 4 from Anaplasma marginale.

Anaplasma marginale is the rickettsia which causes the bovine anaplasmosis. The distribution of A. marginale is both tropical and subtropical regions of the world.
