AIM The present study was undertaken to study the pathology and control of sudden unexplained mortality in wistar rats. MATERIALS AND METHODS This study was conducted in a colony of 25 male wistar rats where there was mortality of nine rats. The dead rats were subjected to thorough post-mortem examination and necropsy samples were processed for hematoxylin and eosin staining for histopatholog...

Parasitic nematodes infect hundreds of millions of people and farmed livestock. Further, plant parasitic nematodes result in major crop damage. The pipeline of therapeutic compounds is limited and parasite resistance to the existing anthelmintic compounds is a global threat. We have developed an INVertebrate Automated Phenotyping Platform (INVAPP) for high-throughput, plate-based chemical scree...

Malnutrition, anaemia, and gut parasites are commonly interrelated. Using the Nippostrongylus brasiliensis-rat model, the effect of iron and protein deficiency on the efficacy of benzimidazole anthelmintics was studied. It was demonstrated that the anthelmintics mebendazole and fenbendazole were significantly less effective in eradicating parasites when animals were deficient in iron and protei...

Benzimidazoles anthelmintics, which enter into environment primarily through excretion in the feces or urine of treated animals, can affect various organisms and disrupt ecosystem balance. The present study was designed to test the phytotoxicity and biotransformation of the three benzimidazole anthelmintics albendazole (ABZ), fenbendazole (FBZ) and flubendazole (FLU) in the harebell (Campanula ...

Prolonged use of broad-spectrum antibiotics disrupts the indigenous gut microbiota, which consequently enables toxigenic Clostridium difficile species to proliferate and cause infection. The burden of C. difficile infections was exacerbated with the outbreak of hypervirulent strains that produce copious amounts of enterotoxins and spores. In recent past, membrane-active agents have generated a ...

The objective of this study was to assess the efficacy commercial anthelmintics in horses naturally infected with gastrointestinal nematodes from southern Rio Grande do Sul state, Brazil. anthelmintic assessed by fecal egg count reduction test (FECRT) and coproculture. Fecal samples were collected 110 animals seven farms located region state Sul, south Criteria used suspect resistance included ...

In animal farming, anthelmintics are regularly applied to control gastrointestinal nematodes. There is plenty of evidence that also non-target organisms, such as dung beetles, are negatively affected by residues of anthelmintics in faeces of domestic ungulates. By contrast, knowledge about possible effects on wild plants is scarce. To bridge this gap of knowledge, we tested for effects of the c...

Maintaining production and economic viability in the face of resistance to multiple anthelmintic actives is a challenge for farmers in many countries. In this situation, most farmers in New Zealand rely on the use of combination products, containing multiple actives with similar spectra of activity, in order to maintain control. However, there are concerns that use of combinations, once resista...

Gastrointestinal nematode infections pose a major threat to small ruminant production. is a helminth parasite that feeds on blood of small ruminant animals and causes anaemia, anorexia, loss of condition, and eventual death of the host animal. The parasite is particularly found in tropical and subtropical regions worldwide [1]. In Nigeria and most developing countries, parasitic helminths cause...
