Background: Ruminant mastitis continues to be a cause of economic losses in the dairy industry and remains a major public health hazard globally.
Objectives: This cross-sectional study was carried out in Mukurweini Sub-County of Nyeri County, Kenya, to investigate the prevalence of bacteria causing mastitis, risk factors associated with goat mastitis and the antibiotic resistance profiles of bacteria isolated from the goat milk.
Methods: Farm level data on risk factors for mastitis was obtained from 56 farmers using a semi structured questionnaire.
Human African trypanosomiasis (HAT) develops in two stages namely early stage when trypanosomes are found in the blood and late stage when trypanosomes are found in the central nervous system (CNS). The two environments are different with CNS environment reported as being hostile to the trypanosomes than the blood environment. The clinical symptoms manifested by the disease in the two environments are different.

- * Bacterial analysis identified 19 species, with coagulase-negative staphylococci and Staphylococcus aureus being predominant, showing varied antibiotic resistance including high resistance to ceftazidime and amoxicillin.
- * The findings highlight the urgent need for improved management strategies among farmers and health professionals to address both mastitis and rising antibiotic resistance in cattle.
Article Synopsis
- Antimicrobial resistance (AMR) is an increasing global health concern, necessitating baseline data on the prevalence and characteristics of drug-resistant bacteria, particularly in pastoralist communities in Kenya.
- A study analyzed nasal swabs from 176 healthy pastoralists in Kajiado Central, revealing high rates of bacteria: coagulase-negative Staphylococcus (CoNS) at 44.9% and Staphylococcus aureus at 43.2%, along with notable antibiotic resistance levels.
- Factors such as gender and raw milk consumption were linked to higher instances of multi-drug resistant (MDR) bacteria, particularly among males, suggesting a need for further research and interventions to combat AMR in the region.
Infertility remains a challenge in breeding herds in most developing countries. In the current study, 104 penile sheath washes were collected from bulls of different breeds and ages from different cattle breeding farms in Zimbabwe. The samples were submitted to the Central Veterinary Laboratory, Zimbabwe, for screening of species using the polymerase chain reaction (PCR).
