AI Article Synopsis
- Bovine respiratory infections are a major economic issue for the cattle industry globally, including in Turkey, with Influenza D virus (IDV) potentially contributing to these diseases.
- A study was conducted to investigate the presence of IDV in cattle across Turkey, particularly in farms with high rates of respiratory disease and calf mortality.
- Out of 76 samples collected from 12 herds, IDV was identified in three cattle, with genetic analysis revealing a 95% similarity to strains found in Europe and the U.S., underscoring the need for ongoing monitoring of this virus in the Turkish cattle industry.
Article Abstract
Bovine respiratory infections are the most economically important diseases affecting the cattle industry worldwide including Turkey. Influenza D virus (IDV) could play an important role to trigger bovine respiratory disease (BRD) complex. Since, there is no data about the presence and genotypes of IDV in Turkish cattle herds; this study was performed to investigate IDV in cattle in Turkey. Animals analyzed in this study were from commercial cattle farms having respiratory disease in calves with significant mortality. Nasal swabs and tissue samples from cattle in Marmara, Inner Anatolia and Aegean region of Turkey were analyzed by real-time RT-PCR assay to detect IDV. Among 76 samples form 12 cattle herds, IDV was detected in 3 cattle in a herd. Sequencing and phylogenetic analysis of partial hemagglutinin esterase fusion (HEF) gene showed that the Turkish strain is 95% identical to its European and US counterparts, which suggest intercontinental spread of the virus. These findings highlight the need for future continuous surveillance on larger scale to determine the distribution pattern and evolution of this novel emerging pathogen in Turkish cattle industry.

Article Synopsis
- The study aimed to investigate the genetic diversity of specific DNA microsatellites from the bovine genome and their relationship to milk yield in Awassi sheep, based on comparisons of bovine and ovine genome mapping.
- Eighteen microsatellite markers tied to milk yield (from previous bovine studies) were analyzed in Awassi sheep using PCR amplification to evaluate genetic variation and their impact on milk production.
- Results indicated that the 123 bp allele at the BMS1341 marker on BTA2 significantly increased daily milk yield (P < 0.01), while several other markers also showed moderate significance in influencing the yield (P < 0.05).

Vector-borne pathogens continue to increase their impact on the livestock industry worldwide. To protect animals against these pathogens, it is very important to identify the species that cause the disease and understand their prevalence. This study aimed to investigate the presence and prevalence of vector-borne pathogens in apparently healthy cattle in different parts of Kyrgyzstan using molecular diagnostic techniques.

Article Synopsis
- Brucellosis is a sickness caused by bacteria that affects both people and animals, causing health problems and money loss in farming in Türkiye and other countries.
- Researchers studied the genes of 106 samples from animals and humans in Türkiye to understand how they differ from each other and from samples in other countries.
- The study found different types of the bacteria in Türkiye, showing they are also related to bacteria from neighboring countries and some European countries, which means travel might help spread the disease, so better controls are needed to keep it from spreading.

Article Synopsis
- Anaplasma is a type of bacteria that can make sheep and goats sick, and this study looked at how common it is in animals from Faisalabad, Pakistan.
- Out of 384 blood samples taken, 131 tested positive for Anaplasma, showing it’s more common in goats (41.88%) than in sheep (22.00%).
- The study also found that factors like where the animals live, if they have ticks, their age, and how clean their surroundings are can affect their chances of getting sick.

IntroductionEnterococcus, which used to be thought of as a harmless commensal living in the digestive tract, has now become a highly resistant and highly contagious pathogen that makes nosocomial infections much more common. This study examined enterococci species and their antibiotic resistance phenotypes and genotypes and virulence gene content in Turkish ground beef samples. Methodology A total of 100 ground beef samples were analyzed between May 2020 and May 2021.
