Overview

What is he best known for?

The fields of study he is best known for:

  • Genetics
  • Biochemistry
  • Disease

Ryan O’Handley focuses on Veterinary medicine, Giardia, Dairy cattle, Feces and Cryptosporidium parvum. Ryan O’Handley works mostly in the field of Veterinary medicine, limiting it down to topics relating to Neospora caninum and, in certain cases, Coccidiosis, as a part of the same area of interest. The study incorporates disciplines such as Giardia Infections and Cryptosporidium in addition to Giardia.

His Cryptosporidium study is focused on Microbiology in general. His Dairy cattle research incorporates elements of Intestinal cryptosporidiosis, Herd, Serology and Disease. Ryan O’Handley has researched Feces in several fields, including Giardiosis, Diarrhea and Animal science.

His most cited work include:

  • Update on Cryptosporidium and Giardia infections in cattle (234 citations)
  • Duration of naturally acquired giardiosis and cryptosporidiosis in dairy calves and their association with diarrhea. (222 citations)
  • The public health and clinical significance of Giardia and Cryptosporidium in domestic animals. (206 citations)

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

The scientist’s investigation covers issues in Veterinary medicine, Microbiology, Feces, Giardia and Cryptosporidium parvum. His studies deal with areas such as Dairy cattle and Neospora caninum as well as Veterinary medicine. Ryan O’Handley focuses mostly in the field of Microbiology, narrowing it down to topics relating to Giardia duodenalis and, in certain cases, Isospora and Genetics.

His Feces study combines topics from a wide range of disciplines, such as Prevalence, Animal science and Giardia lamblia. His Giardia research includes elements of Pathogen, Disaccharidase, Drug development, Protozoa and Giardia Infections. His Cryptosporidium parvum study combines topics in areas such as Diarrhea and Cryptosporidium.

He most often published in these fields:

  • Veterinary medicine (63.27%)
  • Microbiology (32.65%)
  • Feces (32.65%)

What were the highlights of his more recent work (between 2014-2021)?

  • Microbiology (32.65%)
  • Toxoplasma gondii (8.16%)
  • Staphylococcus aureus (4.08%)

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

His main research concerns Microbiology, Toxoplasma gondii, Staphylococcus aureus, Giardia and Extracellular. His Microbiology research integrates issues from Monensin and Haemolysis. His studies deal with areas such as Zoology, Host, Protozoa and Transmission as well as Toxoplasma gondii.

His studies in Giardia integrate themes in fields like Drug development, Neonatal mouse, Pharmacology and Drug discovery. As a member of one scientific family, Ryan O’Handley mostly works in the field of Giardia duodenalis, focusing on Immunofluorescence and, on occasion, Veterinary medicine. His Veterinary medicine study frequently draws connections to other fields, such as Feces.

Between 2014 and 2021, his most popular works were:

  • Secreted biofilm factors adversely affect cellular wound healing responses in vitro. (24 citations)
  • Robenidine Analogues as Gram-Positive Antibacterial Agents. (17 citations)
  • Gas chromatography-mass spectrometry-based metabolite profiling of Salmonella enterica serovar Typhimurium differentiates between biofilm and planktonic phenotypes (14 citations)

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

  • Biochemistry
  • Genetics
  • Disease

His scientific interests lie mostly in Microbiology, Extracellular, Biofilm, Epidermal cell differentiation and Salmonella enterica. Ryan O’Handley regularly ties together related areas like Hydrochloride in his Microbiology studies. His Hydrochloride investigation overlaps with Alkylation, Imine, Moiety and Polymyxin B.

Among his Alkylation studies, you can observe a synthesis of other disciplines of science such as Methylene, Gram-positive bacteria and Robenidine. Epidermal cell differentiation combines with fields such as Hemolysin Proteins, Staphylococcus aureus, Keratinocyte and Wound healing in his investigation. There are a combination of areas like Biochemistry, Glycine, Amino acid and Metabolome integrated together with his Salmonella enterica study.
