Overview

What is she best known for?

The fields of study she is best known for:

  • Bacteria
  • Internal medicine
  • Antibiotics

Her primary areas of study are Mastitis, Herd, Veterinary medicine, Dairy cattle and Antimicrobial. Pamela L. Ruegg interconnects Antibiotics, Ceftiofur, Staphylococcus aureus and Somatic cell count in the investigation of issues within Mastitis. Her research integrates issues of Milking, Biotechnology, Disease, Subclinical mastitis and Bacteriological Cure in her study of Herd.

Her study in Veterinary medicine is interdisciplinary in nature, drawing from both Biosecurity and Animal feed. Pamela L. Ruegg has researched Dairy cattle in several fields, including Bulk tank and Lactation. Her studies in Antimicrobial integrate themes in fields like Penicillin and Dairy herds.

Her most cited work include:

  • Relationship between udder and leg hygiene scores and subclinical mastitis. (246 citations)
  • Treatment practices and quantification of antimicrobial drug usage in conventional and organic dairy farms in Wisconsin. (198 citations)
  • Results of milk samples submitted for microbiological examination in Wisconsin from 1994 to 2001. (186 citations)

What are the main themes of her work throughout her whole career to date?

Pamela L. Ruegg spends much of her time researching Mastitis, Veterinary medicine, Herd, Animal science and Somatic cell count. Her work deals with themes such as Internal medicine, Subclinical infection and Lactation, which intersect with Mastitis. Her study focuses on the intersection of Veterinary medicine and fields such as Antimicrobial with connections in the field of Antibiotic resistance and Ceftiofur.

In the subject of general Herd, her work in Bulk tank and Dairy herds is often linked to Management practices, thereby combining diverse domains of study. When carried out as part of a general Animal science research project, her work on Milking is frequently linked to work in Grazing, therefore connecting diverse disciplines of study. Her Somatic cell count study integrates concerns from other disciplines, such as Culling, Incidence and Brown Swiss.

She most often published in these fields:

  • Mastitis (48.94%)
  • Veterinary medicine (40.43%)
  • Herd (35.46%)

What were the highlights of her more recent work (between 2013-2020)?

  • Mastitis (48.94%)
  • Veterinary medicine (40.43%)
  • Somatic cell count (27.66%)

In recent papers she was focusing on the following fields of study:

Her main research concerns Mastitis, Veterinary medicine, Somatic cell count, Herd and Milking. Her Mastitis research is multidisciplinary, relying on both Internal medicine, Subclinical infection, Ceftiofur and Intensive care medicine. Her Veterinary medicine study incorporates themes from Udder, Total bacterial count, Bacterial counts and Intramammary infection.

Her Somatic cell count study combines topics in areas such as Rennet, Casein, Animal science and Brown Swiss. Her Herd research includes elements of Logistic regression, Biotechnology and Hygiene. The study incorporates disciplines such as Conditional logistic regression and Dentistry in addition to Milking.

Between 2013 and 2020, her most popular works were:

  • A 100-Year Review: Mastitis detection, management, and prevention. (143 citations)
  • Treatments of clinical mastitis occurring in cows on 51 large dairy herds in Wisconsin. (63 citations)
  • The effect of storage temperature and duration on the microbial quality of bulk tank milk. (34 citations)

In her most recent research, the most cited papers focused on:

  • Bacteria
  • Internal medicine
  • Antibiotics

The scientist’s investigation covers issues in Mastitis, Veterinary medicine, Herd, Milking and Pirlimycin. Pamela L. Ruegg is interested in Subclinical mastitis, which is a branch of Mastitis. Her Veterinary medicine research includes themes of Bacterial counts and Hetacillin.

Her Herd study combines topics from a wide range of disciplines, such as Gastroenterology, Pregnancy and Subclinical infection. The Milking study combines topics in areas such as Conditional logistic regression, Dentistry and Infection control. Her Pirlimycin research is multidisciplinary, incorporating elements of Streptococcus uberis, Ceftiofur and Staphylococcus epidermidis.
