In order to examine the prevalence of Cryptosporidium infection in wild rodents and insectivores of South Korea and to assess their potential role as a source of human cryptosporidiosis, a total of 199 wild rodents and insectivore specimens were collected from 10 regions of South Korea and screened for Cryptosporidium infection over a period of 2 years (2012-2013). A nested-PCR amplification of Cryptosporidium oocyst wall protein (COWP) gene fragment revealed an overall prevalence of 34.2% (68/199). The sequence analysis of 18S rRNA gene locus of Cryptosporidium was performed from the fecal and cecum samples that tested positive by COWP amplification PCR. As a result, we identified 4 species/genotypes; chipmunk genotype I, cervine genotype I, C. muris, and a new genotype which is closely related to the bear genotype. The new genotype isolated from 12 Apodemus agrarius and 2 Apodemus chejuensis was not previously identified as known species or genotype, and therefore, it is supposed to be a novel genotype. In addition, the host spectrum of Cryptosporidium was extended to A. agrarius and Crosidura lasiura, which had not been reported before. In this study, we found that the Korean wild rodents and insectivores were infected with various Cryptosporidium spp. with large intra-genotypic variationa, indicating that they may function as potential reservoirs transmitting zoonotic Cryptosporidium to livestock and humans.

This study was conducted in Samsun Province of Turkey to investigate the serological status of domesticated water buffaloes for both Crimean-Congo Hemorrhagic Fever (CCHF) and Lumpy Skin Disease (LSD). Serum was collected from a total of 272 water buffaloes from different age groups and both genders; of the total, 48.1% had been vaccinated against LSD with heterologous sheep-goat pox vaccine. The serum samples were individually assessed by using a commercial ID screen enzyme-linked immune-sorbent assay (ELISA) to detect neutralizing antibodies against both CCHF virus and LSD virus. All 272 buffaloes were negative for antibodies against the CCHF virus. All the unvaccinated buffaloes (141) were seronegative for LSD virus but of the 131 vaccinated buffaloes, 10 (7.6%) were seropositive for the LSD virus. In addition, 8.6% of vaccinated animals age >1 year old were seropositive for LSD, whereas the seropositivity was 5.1% for the animals age < 1 year old. There was no significant difference for seropositivity between male and female animals in the >1 year old or < 1 year old age groups. When seroprevalances for LSD in the tested water buffaloes are evaluated by gender, there was a significant difference between females (8.6%) and males (0%) in the >1 year old water buffaloes (X2=20.24; P<0.001). Separately, the results of this study indicate that Bafra district water buffaloes are not infected by CCHFV and LSDV and some of the buffaloes that vaccinated with LSDV did not develop sufficient antibodies to protect them after they were vaccinated for the LSD virus. Furthermore, the authors of this study conclude that both the commercially produced vaccine that is currently administered and the vaccination strategy have to be urgently evaluated by the veterinary authorities in Turkey. This is essential in order to combat the spread of LSD virus infection with an effective vaccine and a comprehensive management strategy across Turkey.

Bovine parainfluenza 3 virus (BPI3V)is one of the most important respiratory
pathogens and a leading cause of serious respiratory illnesses in cattle, both independent of
and in connection with other pathogens involved in the bovine respiratory disease complex
(BRDC). In this study, we aimed to identify the historical circulation of genotype C bovine
BPI3V (BPI3Vc) in Turkey using the archival serum samples of domestic ruminants that had
been collected from six provinces of northern Anatolia in Turkey between 2009-2010. A total
of 896 sera from cattle (n=442), sheep (n=330), and goats (n=124) were randomly selected
and screened with a virus neutralization test in order to detect antibodies for BPI3Vc. The
overall seropositivity rate was 21.09%, with seropositivity rates for cattle, sheep, and goats
of 21.04%, 20.00%, and 24.19%, respectively. Neutralizing antibody titers for selected samples
ranged between 1/4 to 1/512. This study represents the first serological study conducted
using the first BPI3V isolate of Turkey.
