Overview

What is he best known for?

The fields of study he is best known for:

  • Internal medicine
  • Genetics
  • Ecology

His main research concerns Veterinary medicine, Herd, Dairy cattle, Animal science and Helminths. His Veterinary medicine research includes themes of Livestock, Deworming and Toxocara canis. His research in the fields of Dairy herds overlaps with other disciplines such as Economic cost.

His Dairy cattle research focuses on subjects like Anthelmintic, which are linked to Serology and Lactation. His studies in Animal science integrate themes in fields like Eimeria, Excretion and Spore. His Helminths research integrates issues from Feces and Parasitology.

His most cited work include:

  • Epidemiology of Cryptosporidium spp. and Giardia duodenalis on a dairy farm. (131 citations)
  • Value of present diagnostic methods for gastrointestinal nematode infections in ruminants. (124 citations)
  • Anthelmintic treatment of dairy cows and its effect on milk production. (114 citations)

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

Harm W. Ploeger mainly investigates Veterinary medicine, Animal science, Grazing, Herd and Immunology. His specific area of interest is Veterinary medicine, where Harm W. Ploeger studies Anthelmintic. His biological study spans a wide range of topics, including Ivermectin and Ice calving, Lactation.

Harm W. Ploeger works mostly in the field of Animal science, limiting it down to topics relating to Nematode and, in certain cases, Herd health. His work carried out in the field of Grazing brings together such families of science as Ostertagia ostertagi, Serology, Pasture and Haemonchus contortus. His study in Herd is interdisciplinary in nature, drawing from both Dairy cattle and Nematode infection.

He most often published in these fields:

  • Veterinary medicine (54.95%)
  • Animal science (23.42%)
  • Grazing (18.92%)

What were the highlights of his more recent work (between 2012-2021)?

  • Veterinary medicine (54.95%)
  • Feces (14.41%)
  • Deworming (9.01%)

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

His scientific interests lie mostly in Veterinary medicine, Feces, Deworming, Environmental health and Toxocariasis. His study connects Dictyocaulus viviparus and Veterinary medicine. As a part of the same scientific family, Harm W. Ploeger mostly works in the field of Dictyocaulus viviparus, focusing on Ostertagia and, on occasion, Dictyocaulus and Animal science.

As part of the same scientific family, he usually focuses on Feces, concentrating on Parasitology and intersecting with Giardiosis. His Ivermectin study deals with Larva intersecting with Pyrantel and Helminths. The concepts of his Moxidectin study are interwoven with issues in Livestock and Grazing.

Between 2012 and 2021, his most popular works were:

  • Toxocara canis in household dogs: prevalence, risk factors and owners’ attitude towards deworming (43 citations)
  • Environmental contamination with Toxocara eggs : A quantitative approach to estimate the relative contributions of dogs, cats and foxes, and to assess the efficacy of advised interventions in dogs (37 citations)
  • Coprophagy in dogs interferes in the diagnosis of parasitic infections by faecal examination (36 citations)

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

  • Internal medicine
  • Genetics
  • Ecology

His primary areas of study are Veterinary medicine, Deworming, Environmental health, Ivermectin and Moxidectin. His study in Veterinary medicine focuses on Eimeria in particular. Harm W. Ploeger focuses mostly in the field of Deworming, narrowing it down to topics relating to CATS and, in certain cases, Free roaming, Significant risk and Young age.

His Environmental health research includes elements of Gastrointestinal parasites, Dog owners and Toxocara cati, Toxocara canis. His Ivermectin research is multidisciplinary, relying on both Haemonchus contortus, Anthelmintic and Flock. The various areas that Harm W. Ploeger examines in his Moxidectin study include Teladorsagia circumcincta, After treatment, Larva, Period and Excretion.
