The results showed that crocodile contained single circular chromosome with size 1.22–1.23 Mbp plasmid 7.7–8.0 kbp. A containing eight coding sequences (CDSs)...

Abstract The increasing prevalence of methicillin-resistant Staphylococcus aureus (MRSA) emphasises the urgent need for novel antimicrobial agents as alternatives to antibiotics. Bacteriophage therapy is one most promising strategies. Here, we isolated and comprehensively characterized a phage, vB_SauM_VL10 (VL10), from urban sewage. VL10 genome displays 141,746 bp linear double-stranded DNA, containing 193 open reading frames lacking tRNA, virulence, or antibiotic resistance genes....

Bacterial cultures observed under a microscope, graded for cell density, weekly, 12 weeks. Most pathogenic difficult to all conditions. All conditions novel subclade P1 positive within 2 For P2, storing weeks prior resulted in more...

Chlamydia is a known pathogen in both saltwater and freshwater crocodiles. However, the exact species/strain has not been clearly identified. In this study, we successfully cultivated Siamese crocodile McCoy cells at temperature of 30°C. Electron microscopy; phylogeny based on nine conserved taxonomically informative markers, ompA, or seven housekeeping genes; whole-genome sequencing analysis isolate confirmed identity as new member genus Chlamydia, species that name crocodili.

Pseudomonas aeruginosa is a notable nosocomial pathogen that can cause severe infections in humans and animals. The emergence of multidrug resistant (MDR) P. has motivated the development phages to treat infections. In this study, novel phage, vB_PaeS_VL1 (VL1), was isolated from urban sewage. Phylogenetic analyses revealed VL1 species genus Litunavirus subfamily Migulavirinae. virulent phage as no genes encoding lysogeny, toxins or antibiotic resistance were identified. therapeutic...

We collected water and soil samples from a waterfall in Thailand to investigate the presence of potentially pathogenic Leptospira. Isolation Leptospira all 17 environmental was successful. Based on 16S rRNA gene sequence analysis, diverse group species recovered including 2 (Leptospira alstonii [5/17, 29%] kmetyi [1/17, 6%]); 1 intermediate wolffii [9/17, 53%]); non-pathogenic meyeri 6%] idonii 6%]). The high prevalence indicates that may serve as natural reservoir possible pathogens leptospirosis.

The intracellular pathogen Burkholderia pseudomallei, the etiological agent of melioidosis in humans and various animals, is capable survival movement within cytoplasm host cells by a process known as actin-based motility. bacterial factor BimA required for motility through its direct interaction with actin, mediating actin polymerization at single pole bacterium to promote both between cells. However, little about other proteins this process. Here, we have investigated role bimC gene...

Porcine species have been used in preclinical transplantation models for assessing the efficiency and safety of transplants before their application human trials. Porcine-induced pluripotent stem cells (piPSCs) are traditionally established using four transcription factors (4TF): OCT4, SOX2, KLF4, C-MYC. However, inefficiencies reprogramming piPSCs maintenance self-renewal pluripotency remain challenges to be resolved. LIN28 was demonstrated play a vital role induction humans. To investigate...

Pig induced pluripotent stem cell (piPSC) line was generated from embryonic fibroblast cells using retroviral transduction approaches carrying human transcriptional factors: OCT4, SOX2, KLF4, c-MYC and LIN28. The piPSC line, VSMUi001-D, positive for alkaline phosphatase activity expressed the pluripotency associated transcription factors including NANOG surface markers SSEA-1, all iPSC hallmarks of authenticity. Furthermore, VSMUi001-D exhibited a normal karyotype formed embryoid bodies in...

Coronavirus disease (COVID-19) is an emerging infectious caused by SARS-CoV-2. Given the emergence of SARS-CoV-2 variants, continuous surveillance in animals important. To monitor infection wildlife Thailand, we collected 62 blood samples and nine nasal- rectal-swab from captive tigers (Panthera tigris) Ratchaburi province Thailand during 2020-2021. A plaque reduction neutralization test (PRNT) was employed to detect neutralizing antibodies. real-time RT-PCR assay performed RNA. Our findings...

Abstract Phospholipase C (PLC) enzymes are key virulence factors in several pathogenic bacteria. Burkholderia pseudomallei , the causative agent of melioidosis, possesses at least three plc genes ( plc1 plc2 and plc3 ). We found that culture medium gene expression increased with increasing pH, whilst was pH (4.5 to 9.0) independent. Expression not detected medium. All were expressed during macrophage infection by B. K96243. Comparing wild-type mutants revealed plc2, plc12 or plc123 showed...

To explore the prevalence of influenza viruses in these animal species, 196 archival sera from 5 felid species including Panthera tigris (N=147), Prionailurus viverrinus (N=35), leo (N=5), Pardofelis temminckii (N=8) and Neofelis nebulosa (N=1) collected between 2011 2015 10 provinces Thailand were determined for presence antibody avian human viruses. Blocking enzyme-linked immunosorbent (ELISA) assay hemagglutination inhibition (HI) employed...

For a decade, chlamydial and herpesvirus infections have caused significant morbidity mortality in farmed crocodiles. In September 2017, total of 160 juvenile freshwater Siamese crocodiles (Crocodylus siamensis) with conjunctivitis/pharyngitis lesions were admitted at the Veterinary Aquatic Animal Research Health Care Unit, Faculty Science, Mahidol University. All did not respond well to antibiotics or supportive treatments died. This study aimed detect identify causative agents associated...

The reprogramming of cells into induced neural stem (iNSCs), which are faster and safer to generate than pluripotent cells, holds tremendous promise for fundamental frontier research, as well personalized cell-based therapies neurological diseases. However, with viral vectors increases the risk tumor development due vector transgene integration in host cell genome. To circumvent this issue, Sendai virus (SeV) provides an alternative integration-free method that removes danger genetic...

Little is known about the ecology of influenza A virus (IAV) in nonhuman primates (NHPs). We conducted active surveillance IAV among 672 cynomolgus macaques (Macaca fascicularis) living 27 free-ranging colonies Thailand between March and November 2019. hemagglutination inhibition (HI) assay was employed as screening test against 16 subtypes avian (AIV) two strains H1 subtype human virus. The serum samples with HI titers ≥20 were further confirmed by microneutralization (MN) assay. Real-time...
