Abstract In the genome of SARS-CoV-2, 5′-terminus encodes a polyprotein, which is further cleaved into 15 non-structural proteins whereas 3′ terminus four structural and eight accessory proteins. Among these 27 proteins, present study aimed to discover likely antigenic epitopes be used for development vaccine or serodiagnostic assay using an in silico approach. For this purpose, after full analysis SARS-CoV-2 Wuhan isolate variant that are detected frequently, surface including spike,...

Abstract Purpose Anaplasmosis is a tick-borne disease which caused by different Anaplasma species. Among species, A. ovis can infect sheep and goats cause ovine anaplasmosis. In this study, the prevalence of spp. was investigated in 31 breeds from regions Türkiye. Method PCR targeting MSP-4 gene blood samples (n = 366) collected Also, some positive were sequenced for species identification sub-cluster analyses. Results The molecular 43.9% (161/366).

Naegleria fowleri, the brain-eating amoeba, is a free-living amoeboflagellate with three different life cycles (trophozoite, flagellated, and cyst) that lives in variety of habitats around world including warm freshwater soil. It causes disease called naegleriasis leading meningitis primary amoebic meningoencephalitis (PAM) humans. N. fowleri transmitted through contaminated water sources such as insufficiently chlorinated swimming pool or tap water, swimmers are at risk. found all over...

The emergence of tick-borne disease is increasing because the effects temperature rise driven by global warming. In Turkey, 19 pathogens transmitted ticks to humans and animals have been reported. Based on this, this study aimed investigate including Hepatozoon spp., Theileria Babesia Anaplasma Borrelia Bartonella spp. in tick samples (n = 110) collected from different hosts (dogs, cats, cattle, goats, sheep, turtles) molecular methods.To meet objective, were identified morphologically at...

Abstract Background Cryptosporidium spp. are obligate intracellular apicomplexan parasites transmitted to humans and other animals by contaminated water, food, or direct contact. They mainly cause gastrointestinal symptoms, although subclinical infections also common. Cats primarily infected host-adapted felis while C. parvum muris have been detected in some cases. In this study, the molecular prevalence of was investigated screening 399 fecal samples collected from stray cats using nested...

Bartonella spp. are vector-borne pathogens that cause zoonotic infections in humans. One of the most well-known these is cat-scratch disease caused by henselae and clarridgeiae, with cats being major reservoir for two bacteria. Izmir, Turkey home to many stray cats, but their potential role as a transmission humans has not been investigated yet. Therefore, aim this study was investigate prevalence species genetic diversity living Izmir.

Discovery of new Toxoplasma gondii serotyping epitopes is important due to reports showing the influence genotype on severity toxoplasmosis. In Turkey, genotypes belonging type II, III and Africa 1 lineages were mainly detected. The present study focused find out with high discriminative capacity serotype these using well characterized strains isolated from Turkey.To meet this objective, GRA6 GRA7 genes sequenced lineages, B cell inside sequences predicted by Bcepred additional docking...

Abstract Severe acute respiratory syndrome coronavirus 2 had devastating consequences for human health. Despite the introduction of several vaccines, COVID-19 continues to pose a serious health risk due emerging variants concern. DNA vaccines gained importance during pandemic their advantages such as induction both arms immune response, rapid development, stability, and safety profiles. Here, we report immunogenicity protective efficacy vaccine encoding spike protein with D614G mutation...

Abstract Background Bartonella henselae is one of the most commonly identified species associated with several human diseases. Although B. was detected in humans and cats Turkey, they have not been genotyped previously. Therefore, this study aimed to genotype samples (n = 44) isolated from stray using multi-locus sequence typing (MLST) method. For aim, eight different housekeeping markers were amplified by nested PCR then sequenced reveal types (STs) samples. Results Allelic profiles...
