Article Synopsis
  • * Low-coverage whole genome sequencing (lcWGS) enhances the ability to identify population structures and assign individuals to specific breeding groups in the American Redstart songbird.
  • * Combining insights from migratory data with demographic trends can inform conservation strategies, particularly emphasizing the significance of the Northern Temperate-Greater Antilles population for maintaining species diversity.

Background: Bovine tuberculosis is the leading cause of death in cattle and other species worldwide. Quick and precise identification of mycobacteria is critical to control the occurrence of tuberculosis in cattle.

Methods: We developed a fluorescent peptide nucleic acid fluorescence in situ hybridization (PNA-FISH) approach to detect Mycobacterium bovis and Mycobacterium avium in cytological smears and tissue sections of bovines suspected of having tuberculosis.

Background: complex (MAC) is connected to human immunosuppressive diseases, including HIV-AIDS, and may pose a zoonotic threat. MAC causes lymphadenopathy in children, respiratory infection in adults, and generalized infection in immunocompromised individuals. Infection with nontuberculous Mycobacteria (NTM) in humans is now primarily brought on by MAC.

Background: , an opportunistic, zoonotic, apicomplexan parasite, is one of the most common causes of diarrhea in neonatal bovine calves around the globe. Bovine calves act as a major source of infection by excreting huge numbers of highly resistant oocysts in faeces, which can survive for a long time in extreme environmental conditions. As low as ten oocysts can cause disease and mortality, leading to the requirement of an early and accurate diagnosis for proper and favorable prognosis, management, and control.

Background: Bovine tuberculosis (bTB) is a major bacterial disease that causes significant economic disruption across the globe.

Aims: Our study was based on using a fluorescence polarization assay (FPA) that used fluorescein-labeled ESAT-6 protein to detect antibodies in bovine serum.

Methods: The ESAT-6 protein was used in a FPA.

Many transcription factors contain intrinsically disordered transcription activation domains (TADs), which mediate interactions with coactivators to activate transcription. Historically, DNA-binding domains and TADs have been considered as modular units, but recent studies have shown that TADs can influence DNA binding. Whether these results can be generalized to more TADs is not clear.

The novel severe respiratory syndrome-like coronavirus (SARS-CoV-2) causes COVID-19 in humans and is responsible for one of the most destructive pandemics of the last century. At the root of SARS-CoV infection is the interaction between the viral spike protein and the human angiotensin converting enzyme 2 protein, which allows the virus to gain entry into host cells through endocytosis. In this work, we apply hydrogen-deuterium exchange mass spectrometry (HDX-MS) to provide a detailed view of the functional footprint and conformational dynamics associated with this interaction.

Setting: Studies evaluating Xpert MTB/RIF Ultra assay (Xpert Ultra) for diagnosing tuberculous meningitis (TBM) are scarce and have reported contrasting results in comparison to Xpert MTB/RIF assay (Xpert).

Objective: To evaluate the performance of Xpert Ultra in diagnosing TBM and compare it with Xpert and multiplex polymerase chain reaction (MPCR).

Design: Xpert Ultra was performed on 244 cerebrospinal fluid (CSF) samples: 56 definite TBM, 148 probable TBM and 40 non-TBM controls.

Background: Bovine tuberculosis (bTB) is a chronic disease of cattle with high economic importance in livestock farming caused by and bears a zoonotic potential. There are some non-tuberculous mycobacteria (NTM) which cause disease similar to bTB and interfere with diagnosis of bTB. Non-tuberculous mycobacteria are saprophytic in nature but some of them may cause pulmonary infections, mastitis, lesions in respiratory tract and lymph nodes of cattle, due to which they are being recognized worldwide and interfere with the diagnosis of bTB.

Wild wheat species Aegilops peregrina (UUSS), harbours resistance to various diseases including leaf rust and stripe rust. Inheritance studies in a recombinant inbred line population of wheat-Ae. peregrina introgression line IL pau16061 revealed the transfer of a single major dominant gene conditioning all stage resistance, herein temporarily designated as LrAp.

Background: Paratuberculosis and tuberculosis (TB) caused by (MAP) and complex (MTC), respectively are economically important, chronic debilitating diseases affecting the dairy herds and are also potential zoonotic threats.

Aims: Differential diagnosis of paratuberculosis and TB in blood samples of cattle and buffaloes.

Methods: In this study, an in-house developed multiplex polymerase chain reaction (PCR) targeting MAP, and was used in blood samples (buffy coat) parallel with IS PCR and B PCR for diagnosis of paratuberculosis and TB, respectively; in a total of 202 cattle and buffaloes.

The ankyrin repeat (AR) structure is a common protein-protein interaction motif and ankyrin repeat proteins comprise a vast family across a large array of different taxa. Natural AR proteins adopt a conserved fold comprised of several repeats with the N- and C-terminal repeats generally being of more divergent sequences. Obtaining experimental crystal structures for natural ankyrin repeat domains (ARD) can be difficult and often requires complexation with a binding partner.

Migratory waterfowl and shorebirds are known to be important reservoirs for influenza A viruses (IAV) and they have been repeatedly implicated as causing avian influenza virus (AIV) outbreaks in domestic poultry flocks worldwide. In recent years, wild birds have been implicated in spreading zoonotic H5 influenza viruses to many countries, which has generated high levels of public health concern. Trinidad and Tobago (T&T) is positioned along the wintering route of migratory birds from the Americas; every year, many species of wild birds stopover on the islands of T&T, potentially carrying AIVs and exposing local populations of wild and domestic birds, including commercial poultry, to infection.

The main nuclear factor kappa B transcription factor family members RelA-p50 heterodimer and RelA homodimer have different biological functions and show different transcriptional activation profiles. To investigate whether the two family members adopt a similar conformation in their free states, we performed hydrogen-deuterium exchange mass spectrometry, all-atom molecular dynamics simulations, and stopped-flow binding kinetics experiments. Surprisingly, the N-terminal DNA-binding domains adopt an open conformation in RelA-p50 but a closed conformation in RelA homodimer.
