Myocarditis is considered a fatal form of foot-and-mouth disease (FMD) in suckling calves. In the present study, a total of 17 calves under 4 months of age and suspected clinically for FMD were examined for clinical lesions, respiratory rate, heart rate, and heart rhythm. Lesion samples, saliva, nasal swabs, and whole blood were collected from suspected calves and subjected to Sandwich ELISA and reverse transcription multiplex polymerase chain reaction (RT-mPCR) for detection and serotyping of FMD virus (FMDV).

- * A total of 235 samples, including raw meat, fish products, and milk, were tested, revealing a 7.23% contamination rate with C. difficile, consisting of both toxigenic and non-toxigenic strains.
- * Contamination was found mainly in meat and dry fish, while milk products showed no contamination; the study also noted varying toxin profiles and the highest antibiotic resistance in non-toxigenic isolates.
Newcastle disease virus (NDV) affects commercial poultry as well as other avian species in the wild and in captivity. Although the diversity of NDV in domestic chickens has been well understood, little light has been shed on NDV outbreaks in other avian species. We provide an annotated sequence of NDV/Owl/Guwahati/01/20, a virulent strain of NDV isolated from barn owls in captivity from Guwahati in Northeast India.

- The study aims to address the lack of a suitable vaccine for Necrotic Enteritis (NE) in the Indian broiler industry by investigating the prevalence and characteristics of C. perfringens type G in affected chickens.
- Researchers screened intestinal scrapings and faecal contents, finding that over 51% of suspected cases contained the pathogenic C. perfringens type G, with some strains showing multidrug resistance.
- The prepared sonicated supernatant (SS) vaccine demonstrated a significantly better immunogenic response compared to traditional preparations, highlighting the importance of the TpeL toxin in NE and suggesting SS as an effective immunization method.
