|Abstract: The present study was conducted to determine the alterations in haematological parameters and stress markers in naturally Balantidium coli infected buffaloes, along with this efficacy of polyherbal anti-stressor product Restobal (Restobal®, M/s Ayurvet Limited) was also evaluated against the stress induced by B. coli. In present study, a total of ten apparently healthy buffaloes were selected and considered as control group while twenty buffaloes with natural B. coli infection were included in the disease group and considered for treatment trial. In all the clinical cases, clinical examination and detailed appraisal of haemato-biochemical profiles were carried out. For treatment trial, a total of twenty diseased buffaloes were divided into two groups with ten buffaloes in each group. In therapeutic trials (group I) buffaloes were administered with specific medication against B. coli infection and in herbal trail buffaloes (group II) were administered with specific medication against B. coli infection along with the commercial polyherbal anti stressor product (Restobal). Findings of present study revealed that buffaloes with B. coli infection have reduced haemoglobin levels, total erythrocyte count and monocyte count with increased total leukocyte, neutrophil, lymphocyte, eosinophil count and serum cortisol levels than the apparently healthy buffaloes which indicative of stress due to disease. Buffaloes administered with oral polyherbal anti stressors product showed the significant difference from the group I by elevation of haemoglobin parameters, packed cell volume and serum cortisol levels along with variations in the vital parameters. In conclusion, polyherbal anti stressor product which contains Ocimum sanctum, Phyllanthus emblica, Mangifera indica and Withania somnifera can be recommended along with the specific disease therapeutic protocol in buffaloes to the management of disease induced stress.|

Protozoan diseases have economic importance in ruminants and other animals. Among the different protozoan diseases, balantidiasis (Balantidium coli infection) is a common disease of ruminants including cattle and buffaloes. It usually presents in the apparently healthy animals but under certain circumstances, it also causes clinical diseases in bovines (Sivajothi & Reddy, 2018). During the pathogenesis, it produces the hyaluronidase which potentially enhancing the ability of parasites to invade the mucosa further causes passing of watery persistent foetid dung, dehydration, loss of body condition and leads to the development of stress (Roy et al., 2011). During the period of stress, excessive levels of cortisol will be released which causes impaired regular functions of host and various endocrinal responses. Management of stress is essential to maintain the regular production and reproduction in animals. Studies on the management of stress during the disease conditions are very limited (Schuster & Ramirez, 2008). In previous literature, the efficacy of the herbal product reported as supportive therapy during the vaccination stress in buffaloes (Sivajothi et al., 2018a; Sivajothi et al., 2018b). Hence, the present study was conducted to evaluate the stress parameters in buffaloes with clinical disease and efficacy of the polyherbal anti-stressor product (Restobal®, M/s Ayurvet Limited) which contains Ocimum sanctum, Phyllanthus emblica, Mangifera indica and Withania somnifera against the management of stress caused by Balantidium coli the disease in buffaloes.
2. Materials and Methods
2.1 Experimental Animals
The present study was conducted at College of Veterinary Science, Proddatur, YSR Kadapa District of Andhra Pradesh, India. For present study, a total of ten apparently healthy buffaloes were selected and considered as a control group to compare the haematological parameters in diseased buffaloes. Twenty buffaloes with natural B. coli infection were included in the disease group and separated into two groups equally. Buffaloes in group I were treated for specific B. coli infection alone and buffaloes in groups II were treated for B. coli infection along with administration of oral polyherbal anti stressor preparation (Restobal®, M/s Ayurvet Limited @ 50 ml orally BID).
2.2 Clinical examination
A detailed clinical and physical examination of the individual buffalo was carried out in both groups of buffaloes. Blood samples were collected from the buffaloes in both the groups on the 0th day, 3rd day and 5th day of post treatment. Three ml of whole blood with disodium ethylene diamine tetracetic acid (EDTA) was collected for haemogram and five ml of blood was collected into the vial containing clot activator for serum separation for estimation of serum cortisol levels.
2.3 Laboratory analysis
Whole blood sample was utilized for the estimation of red blood cell count (RBC), haemoglobin concentration (Hb), packed cell volume (PCV), total leukocyte count (TLC) and differential leukocyte counts (DLC) and serum was utilized for the estimation of cortisol by the standard procedures according to the test kit (Feldman et al., 2000).
2.4 Study Analysis
B. coli infection was diagnosed by the demonstration of the both trophozoites and cysts of B. coli in dung samples. Clinically diseased buffaloes were showed reduced feed and water intake, passing of watery and foul smell dung mixed with blood and drastic reduction in the milk yield. Daily feed intake and leftover feed by the individual animal and milk production were recorded throughout the study period.
Buffaloes with clinical B. coli infection in both the groups were treated with injection oxytetracycline @ 10 mg/kg body weight, intravenously, BID for three days; injection meloxicam @ 0.5 mg/kg body weight intramuscularly once; injection metronidazole @ 20 mg/kg body weight intravenously BID; intravenous fluids were administered (@ 10 ml mg/kg body weight) for three days and oral bolus containing metronidazole and furazolidone was given twice in a day for seven days (Sivajothi & Reddy, 2018).
2.6 Statistical analysis
Recorded data were presented as the mean ± standard error (SE) and subjected to statistical analysis using student’s t - test and one - way analysis of variance by using SPSS version 20.0. If P > 0.05 considered as statistically not significant, P ≤ 0.05 considered as statistically significant and P ≤ 0.01 considered as statistically highly significant at 95 % level of significance.
3.1 Clinical and laboratory findings in diseased buffaloes
Findings of present study revealed that buffaloes with B. coli infection showed elevated vital parameters including rectal temperature, heart rate and pulse rate. All the buffaloes with clinical diseases had reduced milk production (50 to 80 % of the initial production). Haematology revealed reduced haemoglobin levels, total erythrocyte count and monocyte count with increased total leukocyte, neutrophil, lymphocyte, eosinophil count and serum cortisol levels than the apparently healthy buffaloes. Clinical, haematological changes during the disease stress were mentioned in Table 1.
3.2 Clinical and laboratory findings in group I and group II
Observed clinical, haematological, cortisol levels in group I and group II of buffaloes were presented in Table 2. Buffaloes in the group II showed significant variation from the group I buffaloes i.e. elevated levels of haemoglobin and reduction in the packed cell volume; reduction in the serum cortisol levels; reduction in the heart rate, pulse rate and respiratory rate of the individual buffaloes.
Variations in the diseased buffaloes suggested that B. coli infection induces changes in vital, haematological biochemical parameters and stress markers which are indication of stress due to disease. Recorded abnormal haematological findings were in association with the previous findings and suggestive of stress due to disease in buffaloes (Schuster & Ramirez, 2008; Sivajothi & Reddy, 2017). In both the groups of buffaloes, reduction in the daily feed intake was noticed as a common finding and leftover roughage was noticed throughout the study period and there is no variation in between the groups during the trial period. All the buffaloes with clinical B. coli infection responded well to the given therapy. The response in the activity, consistency of the dung, reduction in the frequency of dung was improved by the third day of therapy and total duration required to attain the normal state of the animals was four to eight days. After therapy, buffaloes showed increased haemoglobin, reduced packed cell volume, total leukocyte count, lymphocyte count and cortisol levels (Padgett & Glaser, 2003).
Protozoan diseases cause anaemia in bovines in association with the dysentery (Reddy et al., 2015). Transmission of the B. coli infection occurs through the ingestion of food or water contaminated with cysts of Balantidium sp. It affects the small and large intestine and causes mainly by invading the colon and asymptomatic to serious dysentery (Ahmad & Rasad, 2011). Diagnosis of balantidiasis is done by demonstration of any of the development stages including cysts or trophozoites in dung (Sudan et al., 2012). During the disease management, the therapeutic efficacy of the different drugs mainly determined on the basis of the disappearance of clinical signs and reduction of cysts/trophozoites in dung. The therapeutic efficacies of various drugs like nitro heterocyclic compounds, secnidazole, metronidazole, benznidazole and furazolidone have been documented against B. coli (Tarrar et al., 2008).
Stress causes different changes in neurotransmitter activity which results in a cascade of hormonal release from the hypothalamus pituitary adrenal (HPA) axis resulting in an increase in blood corticosterone levels which in turn lead to an increase in serum triglycerides levels and hyperglycemia (Kumar et al., 2013). Stress is a reflex reaction revealed by the inability of an animal to cope with its environment, to the unfavourable conditions. Stress had the impact on growth, production, reproduction and susceptibility to other diseases (Yang & Glaser, 2000). The polyherbal product utilized in the present study was Restobal® (M/s Ayurvet Limited) which contains O. sanctum, P. emblica, M. indica and W. somnifera etc. Medicinal properties of these plant materials are well reported by various researchers (Kumar et al., 2012; Prakash et al., 2012; Sharma et al., 2013). These plant materials have strong anti-stress, antioxidant haemopoeitic and rejuvenating properties. Further, an increase in antioxidant defence, that is, enzymes SOD, CAT and ascorbic acid has been also well document, whereas a significant decrease in lipid peroxidation was also reported. Changes in these parameters proved that the buffaloes with restobal treatment were free from stress. Restobal is recommended to the buffaloes with the specific disease and it can be used as adjuvant therapy to enhance the speed of recovery as well as to quickly attain normal health status.
The present study reports B. coli infection in buffaloes and higher level of stress markers was also reported during the infection. Result of study suggests the use of polyherbal anti stressor product Restobal® (M/s Ayurvet Limited), as an adjuvant therapy for the management of stress developed due to B. Coli infection in buffaloes.
