In this study, I report an unexpected case of a Holstein calf that developed horns even though the sire was homozygous and the dam was heterozygous for polledness. After verifying and confirming the correct parentage, the parents and offspring were genotyped with the Illumina EuroG_MD BeadChip and the SNPs in the polled region on chromosome 1 were evaluated. In addition, the father was sequenced with next generation sequencing to identify possible, previously unknown variants.

- The study investigates the genetic factors influencing milk production traits in 374 Holstein heifers using a genome-wide association study (GWAS) approach.
- It finds moderate to high heritability estimates (0.32-0.54) for traits like 100-day and 305-day milk yield, suggesting that targeted genetic improvements are possible.
- The analysis identifies key single nucleotide polymorphisms (SNPs) linked to milk yield and highlights several important genes, which could help inform breeding strategies for better milk production in Holstein cattle.
Article Synopsis
- Corynebacterium auriscanis is commonly found in dogs with skin infections and can spread to humans through bites, but its pathogenic functions are not well understood.
- This study aimed to analyze the genomes of three C. auriscanis strains to identify genes linked to its virulence and survival mechanisms.
- Findings revealed 42 potential virulence factors, but none categorized as true virulence factors, indicating that C. auriscanis behaves more like an opportunistic pathogen rather than a primary one.
Occurrence, genetic diversity, and antimicrobial resistance of methicillin-resistant Staphylococcus spp. in hospitalized and non-hospitalized cats in Brazil.

Article Synopsis
- A study was conducted to investigate the presence and characteristics of Staphylococcus spp. in both hospitalized and non-hospitalized cats, focusing on methicillin-resistant strains.
- A total of 218 swabs were taken from 109 cats, and various identification and genetic analysis techniques were used to isolate and categorize the bacteria.
- The findings indicated that S. felis was most common in non-hospitalized cats, while MRS strains such as MRSH and MRSP were primarily found in hospitalized ones, with factors like antibiotic use, hospitalization, and comorbidities linked to higher prevalence rates.
