Further evidence of the host plasticity of porcine circovirus-2: detection of the virus in domestic dogs in Namibia.

Porcine circovirus 2 (PCV-2) is a major pathogen of swine, causing significant production losses in the pig industry worldwide. Several studies have detected the virus in different species, both in asymptomatic and diseased subjects, highlighting PCV-2 host plasticity. As PCV-2 has been identified in carnivores, the present study was undertaken to investigate the susceptibility of domestic dogs to PCV-2 infection by testing archived blood samples originating from low-income rural areas in Namibia.

Synthesis, Characterization, Anti-Nematicidal, and Computational Study of Copper(II) Complex Derived From Fluoro-substituted Schiff Base Ligand.

In this study, a novel fluoro-substituted Schiff base ligand (HL) was synthesized through a condensation reaction between 2-bromo-4-(trifluoromethoxy)aniline and 2-hydroxybenzaldehyde in methanol solvent at room temperature. The ligand was subsequently reacted with copper(II) acetate to produce the corresponding Cu(II) complex (CuL). Both the ligand and its complex underwent characterization using various techniques including nuclear magnetic resonance, ultraviolet-visible, Fourier-transform infrared, thermogravimetric analysis, elemental analysis, and mass spectroscopy.

Insect-specific Alphamesonivirus-1 () in lymph node and lung tissues from two horses with acute respiratory syndrome.

Unlabelled: Members of the RNA virus order infect hosts ranging from marine invertebrates to terrestrial mammals. As such, understanding the determinants of host range in this group of viruses, as well as their patterns of emergence and disease potential, is of clear importance. The are a recently documented family within the .

Retrospective analysis of CD4 count trends in South Africa.

Background: South Africa has the largest HIV epidemic globally. Despite the scale-up of antiretroviral therapy, people living with HIV are still presenting with low CD4 counts.

Objectives: This study assessed CD4 trends.
