Expression of Chitinase-like 3 Protein 1 (CHI3L1) in Buffalo Cumulus-oocyte Complexes during in vitro Maturation J. Vijay Anand, K. Brindha, M. Parthiban, P. Raja, S. Parthiban, A. Raja, S. Meignanalakshmi Indian Journal of Animal Research, 2026 Background: Buffaloes (Bubalus bubalis) are a vital livestock species in South Asia, significantly contributing to milk production and agricultural sustainability. However, reproductive inefficiency remains a significant challenge, adversely impacting productivity. In vitro maturation (IVM) of oocytes is a critical technique for improving reproductive efficiency in buffaloes. Chitinase-3-like Protein 1 (CHI3L1), known for its roles in tissue remodelling and inflammation, has emerged as a potential regulator in reproductive processes. This study investigates the expression of CHI3L1 in buffalo cumulus-oocyte complexes (COCs) during IVM to explore its role in oocyte maturation. Methods: Buffalo ovaries were collected post-slaughter and COCs were retrieved and cultured in TCM 199 medium supplemented with FSH, LH and estradiol. The COCs were classified into immature and mature groups based on morphological criteria after 24 hours of culture. Total RNA was extracted from both groups and CHI3L1 expression was quantified using quantitative real-time PCR (qRT-PCR). Western blot analysis was performed to assess CHI3L1 protein levels in both immature and mature oocytes. Result: The study found a significant upregulation of CHI3L1 expression in mature COCs, with a 3-fold increase compared to immature COCs (p less than 0.05). Western blot analysis confirmed the higher intensity of CHI3L1 protein in mature oocytes, correlating with the qRT-PCR results. These findings suggest that CHI3L1 plays a crucial role in the maturation of buffalo oocytes, potentially through its involvement in tissue remodelling and inflammatory responses within the COCs.
MOLECULAR AND PATHOLOGICAL EVIDENCE OF DUCK VIRAL ENTERITIS: FIRST CONFIRMED REPORT IN MANILA DUCK (CAIRINA MOSCHATA) IN SOUTHERN INDIA Durairajan R., Parthiban S., Ramesh J., Ramya R., Jayanthi B., Karthik K., Murugan M.S. Exploratory Animal and Medical Research, 2024 This study reports the foremost incidence of duck viral enteritis (DVE) outbreak in a freerange flock of 250 Manila ducks from Tamil Nadu, Southern India.A sudden 20% (n=50) mortality was observed in the duck flock, presenting clinical signs such as greenish or blood-stained diarrhea, anorexia, ocular discharge, incoordination, and death.Postmortem examination of randomly selected 10 carcasses revealed blood in the body cavities, hemorrhages in the heart, air sacs, proventriculus, liver, and spleen, and enlargement of kidney, spleen, and liver with necrotic foci.Histopathological examination evidenced congestion and hemorrhages in the proventriculus, heart, and air sacs.The liver exhibited diffused congestion and hepatic steatosis.Spleen evinced congestion, hemorrhages, and multifocal necrotic areas.The small intestine showed blunting and fusion of villi with mononuclear cell infiltration.Screening of pooled viscera demonstrated no specific bacterial etiology and was negative for NDV and DHAV genomes.PCR screening for the DVEV genome targeting partial UL-31 showed amplification of 446bp amplicon in all the 10 carcasses examined.Sequencing and alignment of PCR amplicon from one sample yielded 373 nucleotides encoding 94 amino acids and gene sequence submitted to the GenBank with accession number of OR725707.BLAST homology search showed 100% sequence identity with published Anatid alphaherpesvirus 1 genomes available in GenBank.Phylogenetic analysis revealed specific grouping along with published DVEV genomes of India, Bangladesh, China, USA, and Germany.Further, deduced amino acid comparison with established DVEV amino acid sequences also showed a 100% match to the published DVEV sequences.
MOLECULAR EVIDENCE OF BRUCELLA ABORTUS ASSOCIATED REPRODUCTIVE FAILURE IN DOMESTIC SWINE- AN UNEXPLORED FIELD STUDY IN SOUTHERN INDIA S. Parthiban, Shivani Naidu, P. Raja, M. Parthiban, K. Senthilkumar, T. Muthuramalingam, D. Balasubramanyam, S. Ranganatha, R. Sumanth Kumar Exploratory Animal and Medical Research, 2024 Brucellosis is an infectious bacterial zoonotic disease of domestic and wild animals frequently caused by Brucella abortus, B. ovis, B. melitensis, B. suis, and B. canis species. The present study was conducted on 100 serum samples from swine with a history of abortion and reproductive failure in the southern states of India. The samples were screened by Rose Bengal plate agglutination test (RBPT) and standard tube agglutination test (STAT) for detection and quantification of brucella antibody respectively. The samples were also subjected to 16S rRNA gene and Brucella cell surface salt-extractable (BCSP 31) based PCR assays for Brucella genome screening and confirmation. Brucella genome-positive samples were also subjected to AMOS multiplex PCR for B. abortus, B. ovis, B. melitensis, and B. suis species differential diagnosis. The serological screening revealed 3% (n=3) seropositivity for Brucellosis with antibody tires of 1: 160, 1:160, 1:320 for TL7, TL12 and KA-9 samples respectively. Molecular screening evidenced 5% (n=5) positivity for the Brucella genome including three seropositive samples yielded a specific amplicon of 800 and 223 bp amplicons by 16S rRNA and BCSP-31 PCR respectively. Further species identification by AMOS PCR yielded an amplicon of 498 bp specific to B. abortus genome in all three seropositive samples (TL7, TL12, and KA-9) and two PCR-positive samples (TN17 and KA-21) yielded 285bp amplicon specific to B. suis. Molecular screening of Brucella-positive samples for viral co-infections such as PCV2, PPV, CSFV, and PRRSV evidenced non-involvement of above screened 4 viral aetiologies in all 5 Brucella-positive samples indicating the primary infection of Brucella species.

Sathish, M. Parthiban, V. Yuvachandran Viva, M. Sandhya Bhavani, S. Parthiban, G. Dhinakar Raj, K. Porteen Exploratory Animal and Medical Research, 2024 INTRODUCTIONCanine pyoderma is a prominent infection in dogs.caused by Staphylococcus which is naturally present in canine's skin.The disease is characterized by pusfilled lesions due to secondary bacterial infections triggered by the exponential growth of normal resident or transient flora [1] and also infections like food allergens, environmental allergens, or poor managemental practices.It is more often reported in dogs than cats [2,3,4].The clinical signs include excessive itching, licking, or chewing.The skin will appear crusty or moist and the fur of the canine would be patchy with peeling.
