Prevalence and Phylogenetic Network Analysis of Nosema apis and Nosema ceranae Isolates from Honeybee Colonies in Türkiye.

Purpose: Nosemosis is a disease that infects both Western honeybees (Apis mellifera L.) and Asian honeybees (Apis cerana) and causes colony losses and low productivity worldwide. In order to control nosemosis, it is important to determine the distribution and prevalence of this disease agent in a particular region.

Maturation of immunoglobulin G avidity after inactive gE deleted bovine herpesvirus type 1 (BHV-1) marker vaccination.

Particularly for countries in which the prevalence of infection is high, prevention and control of infectious bovine rhinotracheitis (IBR) can be done by vaccination programs. Recently, marker vaccines have been used in the control and eradication of bovine herpesvirus type 1 (BHV-1) infection. Vaccine protection and virus circulation were estimated by individual serological testing using both gB- and gE-ELISA blocking tests.

Vaccination with recombinant oncosphere antigens reduces the susceptibility of sheep to infection with Taenia multiceps.

Taenia multiceps is a cestode parasite, the larval stage of which encysts in the brain of sheep, goats and cattle causing an often fatal condition. The parasite also causes zoonotic infections in humans. Homologues of the recombinant oncosphere vaccine antigens from Taenia ovis and other Taenia species were identified in T.

Detection of Babesia (Theileria) equi (Laveran, 1901) in horses in the Kars province of Turkey.

This study was carried out in order to detect antibodies to Babesia (Theileria) equi in the local breed of horses in the province of Kars, Turkey. A total of 108 serum samples from apparently healthy horses in eight villages were examined for B. equi antibodies by an indirect immunofluorescent antibody test (IFAT).

Serum protein alterations in dogs naturally infected with Toxoplasma gondii.

We conducted this study to describe the serum electrophoretic pattern in dogs associated with the infection of Toxoplasma gondii (T. gondii). The serum protein pattern of 25 dogs with confirmed T.

Detection of Toxoplasmosis gondii seropositivity in sheep in Yalova by Sabin Feldman Dye Test and Latex Agglutination Test.

Sera collected from 63 sheep older than one year of age in two regions of Yalova were tested for anti- Toxoplasma gondii antibodies using the Sabin-Feldman Dye Test (SFDT) and Latex Agglutination Test (LAT). Of the 63 samples tested, 42 (66.66%) and 41 (65.

Characterization of Newcastle disease viruses isolated from chickens and pigeons in the South Marmara region of Turkey.

Between December 1992 and April 1993, Newcastle disease (ND) outbreaks occurred in a broiler flock, a layer flock, in village chickens of two prefectures and in five pigeon lofts in the South Marmara Region of Turkey. Four viruses from chickens and five from pigeons were isolated from these outbreaks, and identified as Newcastle disease viruses (NDV). All were characterized as velogenic strains based on their mean death time in eggs, ability to form plaques in tissue culture and, for some isolates, intracerebral pathogenicity index and intravenous pathogenicity index tests.
