ABSTRACT

Aim: The study was conducted to determine the intensity of gastrointestinal parasite (GIP) infections and hematological parameters in South African communal indigenous goats in relation to anemia.

Materials and Methods: A total of 288 goats were randomly sampled in areas representing four agro-ecological zones. Fecal and blood samples were collected from the rectum and jugular vein, respectively, of each animal. The number of eggs per gram (EPG) and oocysts per gram (OPG) of feces and the hematological parameters were determined using the modified McMaster technique and a BC-2800Vet® automatic hematology analyzer, respectively. Data were analyzed using the repeated measures techniques of Minitab 17, modeling the covariance structure of the observed data.

Results: Based on EPG and OPG, goats in humid zone were significantly infected (p<0.05) with strongyles, EimeriaMoniezia, and Trichuris spp. Hematological parameters of goats in arid and humid zone were lower (p<0.05) than those in semi-arid and dry sub-humid zone. GIP infection intensities were higher (p<0.05) in young animals than in adult and suckling goats. GIP infection intensity was similar between goat sexes, while hematological parameters were higher (p<0.05) in females. Higher (p<0.05) infection intensities for strongyles (302.90 EPG) and Eimeria (216.09 EPG) were observed in winter compared to summer (strongyles: 302.90, Eimeria: 216.09 EPG). Higher (p<0.05) values for the hematological parameters were observed during summer compared to that in winter.

Conclusion: GIP infection intensity in the winter could be associated with hypochromic and normocytic anemia which likely to affects suckling goats while in the summer could be associated with normochromic and normocytic anemia which likely to affect young goats.

ABSTRACT

Background and Aim: Reepithelialization can be described as the resurfacing of a wound with new epithelium in the process of healing, with the overlapping step from keratinocyte migration and proliferation to the tissue contraction. Zinc oxide-turmeric extract dressing has been proven to have anti-inflammatory properties, but its effectivity in the reepithelialization process is still unknown. This study aimed to determine the effect of a wound dressing consisting of zinc oxide and turmeric extract on wound reepithelialization by assessing the expression of cytokeratin 14 (CK14), epidermal growth factor receptor (EGFR), and epithelial cadherin (E-cadherin).

Materials and Methods: A total of 40 Wistar rats were randomized into four control and four treatment groups (n=5 per group). On day 1, a square-shaped full-thickness skin excision measuring 6×6 mm in size was created in the dorsal thoracic area of the rats, and the wounds were either dressed with a combination of zinc oxide and turmeric extract in the treatment groups or left undressed in the control groups. Then, the rats were sequentially sacrificed on days 3, 5, 7, and 14 to obtain subepithelial excision samples, which were subsequently subjected to immunohistochemistry analysis for the expression of CK14, EGFR, and E-cadherin to ascertain wound reepithelization. The data were tabulated and analyzed using a one-way analysis of variance and least significant difference test.

Results: The highest expression levels of CK14, EGFR, and E-cadherin were observed on days 7 and 14 in the treatment and control groups, respectively. While the expression levels of these markers on day 7 were found to be significantly higher in the treatment than the control groups, no significant difference in the expression levels on day 14 was detected between the control and treatment groups (p<0.05).

Conclusion: A wound dressing consisting of zinc oxide and turmeric extract can help accelerate reepithelization in the wound healing process.

ABSTRACT

Aim: The present investigation was intended to generate some basic data on electrocardiography (ECG) parameters in different breeds and their alterations in respect to sex and age.

Materials and Methods: The present investigation was carried out on 239 owned dogs of 11 different breeds presented to the Institute Veterinary Clinic during 2018-2019. The animals, irrespective of breed and sex were grouped on the basis of their age groups. Recordings of ECG were performed by a single-channel ECG machine (CardiartR, BPL, India) at 25 mm/s paper speed and 10 mm=1 mV calibration keeping the animals on the right lateral recumbence without any anesthesia. Heart rate, along with the amplitude and duration of different waves and complexes was measured.

Results: Heart rate did not vary significantly among breeds, sex, and different age groups. The highest heart rate has been reported in Doberman and the lowest in Beagle. The heart rate was lowest at the age group of 6 months-2.5 years and highest around 10.5-12.5 years irrespective of breed and sex. The incidence of sinus arrhythmia was mostly seen in older dogs. All the waves and complexes did not vary significantly between breeds, age, and sex except P duration which was significantly (p<0.05) higher in Golden retriever and Doberman breeds.

Conclusion: The present investigation generated some reference values of ECG in dogs which will help the clinicians to diagnose different cardiac abnormalities through ECG.

ABSTRACT

Aim: The effects of the inclusion of Aspergillus niger in the diet of Haidong chicks reared in the Qing-Zang high altitude area (China) under hypoxic conditions.

Materials and Methods: A total of 720 Haidong chicks were randomly divided into six groups and fed diets supplemented with 0%, 0.5%, 0.75%, 1.0%, 1.25%, and 1.5% of A. niger to determine blood parameters, intestinal morphology, and gut microflora in Haidong chicks reared in a high altitude environment.

Results: Packed cell volume (PCV), red blood cell (RBC) count, white blood cell count, and hemoglobin concentration increased in the groups fed diets containing A. niger. The administration of A. niger in 1.0% and 1.25% significantly decreased the concentration of Escherichia coli in the cecum, while the concentration of Bifidobacterium and Lactobacillus in the cecum and ileum was increased in the treated groups. When compared to the control groups, villi height, crypt depth, and goblet cell density in the intestine was raised, in general, in the groups treated with A. niger.

Conclusion: These findings suggest that 1.25% A. niger as dietary supplement may improve the resistance to ascites among birds reared under hypoxic conditions.

ABSTRACT

Aim: This study aimed to investigate the pathological effects of the infectious bronchitis virus (IBV) on chicken trachea and kidney tissues and also desired to diagnose the virus genome using a molecular tool.

Materials and Methods: Twenty trachea and kidney samples collected from one broiler farm contain 10,000 chickens at Tikrit city. The chickens showed signs of gasping and mortality (20%) at early ages (20 days old), the presence of IBV investigated using conventional reverse transcriptase-polymerase chain reaction technique with routine histopathological study to tracheal and renal tissue.

Results: Postmortem lesion showed severe respiratory inflammation with abscesses at tracheal bifurcation lead to airway blog. Molecular results showed two genotypes of IBV, one of them not included in primer designer research. The histological study showed different stages of inflammation, degeneration, and necrosis to the renal and tracheal tissues.

Conclusion: The respiratory and renal pathological effect of the virus responsible for the symptoms appeared on the affected chicks that caused mortality, with a high probability of presence of a new viral genotype added to the untranslated region.

ABSTRACT

Background and Aim: Respiratory diseases in young cattle are among the significant cattle pathologies that cause considerable economic damage globally. For the treatment of respiratory diseases, coformulated drugs that increase general nonspecific resistance, exhibit adaptogenic and anti-inflammatory properties, and normalize metabolic processes in animals are currently being used. The aim of our study was to investigate the therapeutic efficacy of the complex drug "gentaminoseleferon", used in the treatment of respiratory diseases in calves, especially in Mycoplasma dispar infection.

Materials and Methods: The animals were divided into three groups. Calves with the first clinical signs of respiratory pathology were randomly divided into two groups. The first experimental group (n=5) was intramuscularly injected with sulfetrisan at a dose of 5-10 mL/animal once per day for 7 days. The second experimental group (n=5) was given gentaminoseleferon at a dose of 1 mL/10 kg of body weight once per day for 7 days. The drugs were not used in the control group, the "healthy animals (n=5)". Blood samples were taken 10 days before and after treatment and compared between the experimental and healthy calves. The changes in the hematological and biochemical parameters of blood and serum were evaluated.

Results: During the recovery process of animals in the experimental groups, a normalization of the hematological and biochemical parameters of blood and serum was noted. Interestingly, in calves of the second experimental group, an increase in the total serum protein content by 2.2% (p<0.05) was recorded in comparison with the first group. The second group, furthermore, showed an increase in Vitamins A, E, and C concentrations by 13.5% (p<0.05), 11.9% (p<0.005), and 15.1% (p<0.0005), respectively, as well as in zinc and iron concentrations by 4.1% (p<0.05) and 9.3% (p<0.0001), respectively. These findings indicate a more pronounced decrease in the inflammatory process in the respiratory system and intensive restoration of metabolism, thereby establishing the high therapeutic efficacy of gentaminoseleferon.

Conclusion: Gentaminoseleferon was proven highly effective in the treatment of calves with respiratory illnesses and in restoring homeostasis in the organisms of animals after treatment, as indicated by the normalization of morphological and biochemical blood parameters with a reduction in the recovery time.

Keywords: blood parameters, calves, gentaminoseleferon, Mycoplasma dispar, respiratory diseases.

ABSTRACT

Background and Aim: Irisin, a novel myocyte-secreted hormone, was proposed to mediate some of the beneficial effects of exercise such as browning of adipocytes, thermogenesis, and metabolic homeostasis. Recently, several animals' models' studies have been performed to investigate the therapeutic impact of irisin in several disorders. Several interventional trials used different doses. However, optimum dose was not determined. This systematic review aims to identify the optimal dose of interventional irisin in mice and rat animal models.

Materials and Methods: Online databases PubMed, Google Scholar, and Springer were systematically searched from 2012 to 2019. The words searched were irisin, irisin and animal model, physical activity, and irisin and irisin dosage. Non-irisin doses, in vitro studies, and factors influencing irisin levels were excluded.

Results: Eleven of the total 391 qualifying studies were included. A daily injection of 500 μg/kg irisin may be the optimum dose of effect in mice and rats.

Conclusion: More studies are required to determine the optimum dose of irisin to be used as a therapeutic intervention based on animal model.
