Abstract:Aim:The present investigation was undertaken to evaluate the blood biochemical metabolites of crossbred cattle suffering from brucellosis, in Khetri region of Kamrup District of Assam, India.Materials and Methods: Blood was collected by venipuncture from the jugular vein using 18 gauge hypodermic needle fitted to a Vacutainer-Leur adapter and evacuated tubes. Samples were screened for Brucella by rose Bengal plate test using plate test antigen. The study consisted of two groups. Group I consisted of healthy cr… Show more
“…Furthermore, cows serologically positive for brucellosis had lower A/G ratios when compared with healthy cows. The result of the present study is partly in agreement with previous reports that documented an increase of serum globulin level in Brucella-affected cows (18), ewes (31), and camels (19), whereas Nath et al (18) reported a significant decrease in albumin concentrations and nonsignificant changes in total protein and A/G ratio between the brucellosis-affected and healthy cows. However, Hamada et al (31) found a nonsignificant difference in albumin and total protein between brucellosis-affected and healthy ewes.…”
Materials and methods
Animals and sample collectionA total of 1100 mature female dairy cows (Holstein-Friesian breed, none vaccinated against brucellosis, 3-5 years age) from private farms (Elbehira Governorate, Egypt) were used. All animal-related procedures were carried out in accordance with the Animal Ethics Committee of the Faculty of Veterinary Medicine, Kafrelsheikh University. Blood samples were collected from the jugular vein.

“…The significantly increases of the liver enzyme (AST) in Brucella infected cows in comparison with the values of healthy cows indicates damage of the liver, which supports the earlier reports. 25,33,59 However, this study recorded lower level of ALT which contradicts the earlier reports. The insignificantly higher level of CK in Brucella-infected cows (1.82 ± 0.19) in comparison with healthy cows (0.96 ± 0.20) is in conformity with earlier reports.…”
Background: Sero-molecular methods have been used for the study on the prevalence and economic impact of brucellosis in Bangladesh. The physio-pathological effects and therapeutic trials against brucellosis in animals or humans could not be traced in the available inland literature.
Objectives: This study was conducted to determine the sero-prevalence and haemato-biochemical and therapeutic responses in Brucella-infected dairy crossbred cows.
Materials and Methods: Sera samples of 552 cross-bred dairy cows of Military Dairy Farm, Jessore and smallholder dairy farms of Sirajgonj and Dhaka were initially screened for Brucella infection with Rapid kit test (RKT) and Rose Bengal test (RBT) and positive samples were tested further with ELISA and PCR for confirmatory diagnosis during the period from January 2018 to June 2019. Out of 11 all tests positive cows, of which four had history of abortion were selected for therapeutic trials with combined long acting oxytetracycline @ 25 mg/kg BW 16 doses at 72 hours intervals and streptomycin @ 25 mg / kg BW 10 doses at 24 hours interval injections. Blood samples of all the Brucella negative control and pre- and post-treatment stages of all the Brucella-infected cows were tested for haemato-biochemical changes and Brucella antibody responses by using ELISA and PCR.
Results: Of the 552 sera screened for Brucella infection, of which 18 (3.26%) cows were found positive with the RKT, RBPT and ELISA, whereas only 11 (1.99%) samples showed positive with PCR. The haemato-biochemical values between Brucella-negative and positive cows and antibiotic pre-treated and post-treated values of Brucella-infected cows were compared and discussed. The antibody titer decreased with antibiotic treatment and increased on with-drawl of the antibiotic at 180 days which indicates that antibiotics only effective against bacteremic form not intracellular stage that caused to relapse. However, of the four treated cows, one became pregnant on artificial insemination with normal reproductive cycle which needs to explore its status in further research.
Conclusions: The haemato-biochemical values in cows affected with sub-clinical brucellosis can determine the extent of harmful effects on the health of cows. Therapy with multiple antibiotics for long period, absence of effective vaccines and the most expensive quarantine and ‘test and slaughter’ methods, brucellosis remains as a challenge for its control and eradication in developing world. Human patients affected with brucellosis is treated with antibiotics with overall neglecting the animal reservoir of Brucella infection, therefore ‘One Health’ approach would be required to control this disease.
“…The current study revealed that the Brucellosis may be behind a significant elevation in serum total protein among tested buffalos which was similar to results recorded by Abou Eiazab in 2015 who found significant elevation in the total protein levels among cows infected with Brucella. Moreover other investigators reported significant increase in serum total protein among cattle infected with Brucellosis (Nath et al, 2014).…”

“…From the current study elevation in cholesterol, triglyceride and creatinine among tested cows were reported which was parallel to observations found by EL Bahgy and Ali in 2017. Moreover in a past study done by Nath et al, (2014), it was observed that serum cholesterol and triglyceride were significantly increased among cattle infected with Brucella. Also others recently found that total cholesterol and LDL values were increased while triglyceride, HDL and VLDL values were decreased among cattle with Brucellosis (Merhan et al, 2017).…”
The present study was undertaken to assess and compare the serum biochemical parameters of buffalos and cows brucellosis with negative ones .A total of ninety three blood samples were collected randomly from different age and flocks of non vaccinated local buffalos and cows. Rose Bengal Plate Test was depended for screening the collected blood samples in addition to measure serum biochemical parameters included total protein, albumin, cholesterol, triglyceride, urea, creatinine, aspartate transaminase (AST) and alanine transaminase ( ALT). It was observed that 12 (12.9%) samples positive for Brucella spp. The results of biochemical parameters shown that ALT, AST and total protein were increased significantly ( p<0.05) in buffalo positive for brucellosis than those of negative results .The values of the albumin, cholesterol, triglyceride, urea and creatinine did not show significant variation between the Brucella positive and negative buffalo. The values of serum cholesterol, triglyceride and creatinine concentrations for Brucella positive cows were declined significantly ( p<0.05) when compared to negative ones . The value of AST was elevated significantly ( p<0.05) in Brucella positive cows. It was noticed that there were no significant differences between positive and negative cows considering total protein, albumin, urea and ALT. cows .These changes in biochemical parameters of the blood indicate that brucellosis causes deteriorative effects on health of buffalo and cows infected with Brucella.
