2022
M. Venkatesan | K. Jayalakshmi | B. Poovarajan | M. Saravanan | S Yogeshpriya | P Selvaraj
A retrospective study was carried out to assess the udder affections of cows that were presented to the Large Animal Medicine Referral Clinic of Veterinary College and Research Institute, Thanjavur, Orathanadu, Tamil Nadu during June 2017 to April 2018. In this study involving 161 cows, 4 cows were found to have udder swelling / abscess diagnosed by ultrasound and percutaneous aspiration done under sonagraphic guidance. Udder ultrasound revealed hyperechoic alveolar tissue with anechoic/ heterogenous content in the affected quarters. Aspirated samples were culturally positive for the isolate Staphylococcus aureus and E. coli. In vitro antibiotic sensitivity test showed highest susceptibility to streptomycin followed by enrofloxacin and ciprofloxacin, gentamicin and amoxycillin with good recovery on treatment.
اظهر المزيد [+] اقل [-]Effect of Phyllanthus emblica on ceruloplasmin in bovine Staphylococcal mastitis.

Sharma, Nitika | Mukherjee, Reena | Ingale, S.L. | Jadhav, Rabindra
Therapeutic and anti-inflammatory potential of aqueous extract of Phyllanthus emblica (Common name - Amla) was evaluated in mastitic cows. The milk Somatic Cell Count (SCC) and ceruloplasmin concentration was significantly (P0.05) higher in mastitic cows prior to treatment. The parameters of mastitic cows treated with P. emblica (group III) and with amoxicillin sulbactum combination (group IV) were compared to that of healthy cows (group I and II). Significant reduction (P0.05) in Somatic Cell Count (SCC) was observed in both the treated groups. The level of ceruloplasmin significantly (P0.05) reduced in group III and IV after treatment. Results of the present experiment indicate reduction of SCC and ceruloplasmin level in the mastitic animals treated with the P.emblica extract. The extract of P. emblica significantly reduced (P0.05) the udder inflammation and helped in lowering the concentration of inflammatory marker ceruloplasmin. Therefore P. emblica extract could be advised for the treatment of bovine mastitis.
اظهر المزيد [+] اقل [-]Haemolytic properties and titration of haemolysins of Staphylococcus aureus of milk origin from cattle and goat with clinical mastitis.

Upadhyay, A. | Kataria, A.K.
Thirty Staphylococcus aureus isolates used in the study obtained from cattle (20) and goat (10) were haemolytic on blood agar. Twenty one of the isolates (14 from cattle, 7 from goats) produced a-haemolysis, 3 produced b-haemolysis (2 from cattle and 1 from goats), and 6 isolates (4 from cattle and 2 from goats) produced both a- and b-haemolysis. The haemolysins tested against erythrocytes from rabbit, cattle and horse in order to demonstrate a-, b- and d-toxins, respectively revealed that a- and b-toxins were produced by all the isolates but b toxin was produced by only 7 isolates from cattle and by 3 from goats. On titration it was recorded that highest titre was recorded for a-toxins (for cattle, 1:2560 and for goat, 1:1280) whereas the highest titres for b and d-toxins was similar (1:160) for cattle as well as goat isolates. The result obtained for qualitative and quantitative haemolysin assays correlated well with the haemolysis pattern seen on the blood agar plates.

Ranjan, Rajeev | Gupta, M.K. | Singh, K.K.
A study was carried out in 2161 quarter milk samples of 550 cows in Durg district Chhattisgarh. Out of 550 animals, 385 (70%) animals were found to be positive for sub clinical mastitis (SCM) by Modified White Side Test (MWST), 432 (78.54%) by Modified California Mastitis Test (MCMT) and 462 (84%) by somatic cell count (SCC). The quarter wise prevalence of sub clinical mastitis was 47.99%, 55.25% and 60.90% by MWST, MCMT and SCC respectively. Prevalence of blind teats was 1.77%. prevalence was highest during second and third lactations and at 5 and 6 years of age. Infection rate was higher during early and late stages of lactation. HF and Jersey cross bred cows were more susceptible than indigenous cows. Microorganisms isolated were predominantly Staphylococci. ABST revealed sensitivity to cefotaxime whereas most of the isolates were resistant to ampicillin.

اظهر المزيد [+] اقل [-]Evaluation of lactate dehydogenase, alkaline phosphatase and aspartate aminotransferase activity in milk as an indicator of subclinical mastitis in Holstein x Hariana cows.

Gera, Sandeep | Guha, Anirban
Pertaining to the scenario at hand milk samples from Holstein x Hariana crossbred cows were investigated for alternation in enzyme activity as influenced by sub clinical mastitis (SCM) and their percent sensitivity,specificity,accuracy,positive and negative predictive values, positive and negative likelihood ratios and correlation with (somatic cell count) SCC were calculated. It was found that SCM influence significantly the activity of ALP at pO.OIand LDH at pO.O5in milk. Aspartate amino transferase activity was not influenced by SCM in milk. Moreover, both were found to be correlated with somaticcellcount, significantly.Fromthe likelihoodratios itwas clearthat both alkalinephosphatase (ALP) and LDH can be used for diagnosis of SCM, but, ALP is the safe indicator of SCM in the present study.
اظهر المزيد [+] اقل [-]Therapeutic and anti-oxidant activity of vitamin E and selenium in bovine Staphylococcal mastitis.
2010
Sharma, Nitika | Mukherjee, Reena | Ingale, S.L. | Jadhav, R.K.
Therapeutic and anti-oxidant potential of vitamin E and selenium was evaluated in mastitic cows. The CMT point score and milk somatic cell count (SCC) was significantly (P0.05) higher in mastitic cows prior to treatment. Reduced activity of enzymatic anti-oxidant catalase was observed in mastitic animals. The parameters studied in mastitic cows treated amoxicillin sulbactum (group II) and with amoxicillin sulbactum, vitamin E and selenium (group III) were compared with that of group I healthy cows. Significant reduction (P0.05) in CMT and SCC was observed in both the treated groups. However, reduction in CMT point score and SCC was more pronounced in group III than group II cows. Synergistic action of antibiotic and vitamin E selenium significantly (P0.05) enhanced the activity of catalase in group III mastitic animals on day 8 time period. Therefore, vitamin E and selenium supplementation could be advised in the therapy of mastitis.
