Special Issue Information

Dear Colleagues,

Diseases, Diagnosis, and Treatment of Bovine Bacterial Infectious is a critical area of veterinary medicine focused on understanding, preventing, diagnosing, and treating bacterial infections in cattle. This field is of utmost importance for both animal welfare and the livestock industry, as healthy cattle are essential for a stable and productive economy. Bacterial Infectious Diseases can range from mild to severe and can have significant economic consequences due to decreased productivity, increased veterinary costs, and potential losses in the livestock industry. Understanding how these diseases spread and identifying risk factors (such as overcrowding, poor sanitation, and stress) is crucial in prevention. Accurate and timely diagnosis is essential for effective treatment and control. Different bacterial infections may present with various clinical signs. These could include fever, coughing, nasal discharge, diarrhea, lameness, and more. Vaccination plays a crucial role in preventing bacterial infections in cattle. It helps stimulate the immune system to produce antibodies against specific pathogens. Responsible use of antibiotics is essential to prevent the development of antibiotic-resistant strains of bacteria. This involves proper dosage, duration, and selection of antibiotics. Effective treatment involves choosing the right antibiotics or antimicrobial agents based on the specific pathogen involved and its sensitivity profile. Ongoing research is uncovering new diagnostic techniques, treatment strategies, and preventive measures to improve the health and well-being of cattle. Understanding and managing bovine bacterial infections also has implications for public health. Some of the bacteria affecting cattle can be zoonotic, meaning they can also infect humans. Overall, the field of Diseases, Diagnosis, and Treatment of Bovine Bacterial Infectious Diseases is integral to ensuring the health and productivity of cattle populations, which in turn has far-reaching impacts on agriculture, food security, and public health. Continual research and collaboration in this area are crucial for the sustainable and responsible management of cattle populations worldwide.

Bovine mastitis is an important and costly disease to dairy cattle. Diagnostic methods usually performed in Brazil are somatic cell counts (SCC) and milk microbiology. Low bacteria shedding in milk implies no colony growth in microbiological tests and false negative results. Streptococcus agalactiae and Staphylococcus aureus are principal pathogens of mixed mastitis. However, S. agalactiae has a higher bacterial release from the mammary gland than S. aureus, affecting microbiological sensitivity to diagnose S. aureus. This study aimed to estimate the SCC and total bacterial count (TBC) from cows according to pathogen isolated in milk and to evaluate variation in S. aureus diagnosis by a microbiological test during S. agalactiae treatment, which is called blitz therapy. Both S. agalactiae and S. aureus presented high SCC means, although S. agalactiae showed shedding of bacteria 2.3 times greater than S. aureus. Microbiological sensitivity to S. aureus increased for 5 months during S. agalactiae treatment. The prevalence of S. agalactiae fell after 5 months of therapeutic procedures. The prevalence of S. aureus increased to 39.0. The results showed that due to high sensitivity, the polymerase chain reaction (PCR) could be used at the beginning of blitz therapy with the goal of S. agalactiae eradication from the dairy herd.
