Aim: The growth promoting effect of the blue-green filamentous alga Spirulina platensis (SP) was observed on meat type Japanese quail with antibiotic growth promoter alternative and immune enhancing power.

Materials and Methods: This study was conducted on 180 Japanese quail chicks for 4 weeks to find out the effect of diet type (vegetarian protein diet [VPD] and fish meal protein diet [FMPD])- Spirulina dose interaction (1 or 2 g/kg diet) on growth perfor-mance, gut microbiota, and sensory meat quality of growing Japanese quails (1-5 weeks old).

Results: Data revealed improvement (p<0.05) of weight gain, feed conversion ratio and European efficiency index due to 1, 2 g (SP)/kg VPD, and 2 g (SP)/kg FMPD, respectively. There was a significant decrease of ileum mean pH value by 1 g (SP)/kg VPD. Concerning gut microbiota, there was a trend toward an increase in Lactobacilli count in both 1; 2 g (SP)/kg VPD and 2 g (SP)/kg FMPD. It was concluded that 1 or 2 g (SP)/kg vegetarian diet may enhance parameters of performance without obvious effect on both meat quality and gut microbiota. Moreover, 1 and/or 2 g (SP) may not be invited to share fish meal based diet for growing Japanese quails.

Conclusion: Using of SP will support the profitable production of Japanese quails fed vegetable protein diet.

Aim: The emergence of multidrug-resistant (MDR) bacteria is the most dangerous threat for the treatment of infectious diseases. The aim of this study was to detect and characterize extended spectrum beta-lactamases (ESBLs) and carbapenemase-producing Klebsiella pneumoniae and Escherichia coli among patients and environment of intensive care units (ICUs) of three tertiary care hospitals in Pakistan.

Materials and Methods: A total of 82 samples from ICU’s patients and inanimate environment (injection trays, wash basins, door handles, hand swabs of professionals, and ICU fridges) were screened for ESBL by culturing on CHROMagar-ESBL. ESBL and carbapenemases production were confirmed by double disc synergy test and modified Hodge’s test, respectively. Polymerase chain reaction was used to detect ESBL encoding genes bla cefotaxime (CTX-M), blaCTX-M-1, blaCTX-M-2, blaCTX-M-9, blaTEM, blaSHV and carbapenemase genes blaKPC, bla New Delhi metallo-beta-lactamase-1, blaOXA-48 and blaVIM.

Results: Overall, ESBL production was found high 30/82 (36.5%) among isolates of which 15.8% K. pneumoniae and 20.7% E. coli were identified. All the K. pneumoniae and majority of E. coli isolates were MDR, i.e., resistance to three or more antimicrobial categories. Molecular characterization showed the blaCTX-M-1 as the predominant genotype found in 17/21 (80%) of the isolates. None of the strains was found positive for carbapenemase-encoding genes.

Conclusion: In conclusion, this study demonstrates the emergence of MDR ESBL producing strains among ICU patients and hospital environment, posing a serious threat for the control of nosocomial infections.

Aim: Chronic exposure to indoxacarb and pulmonary expression of toll-like receptor 9 (TLR-9) in mice.

Materials and Methods: In this study, healthy male Swiss albino mice (n=30) aging 8-10 weeks were used to evaluate TLR-9 expression in lungs of mice following indoxacarb exposure with and without lipopolysaccharide (LPS). Indoxacarb was administered orally dissolved in groundnut oil at 4 and 2 mg/kg/day for 90 days. On day 91, five animals from each group were challenged with LPS/normal saline solution at 80 μg/animal. The lung tissues were processed for real time and immunohistochemical studies.

Results: LPS resulted increase in fold change m-RNA expression level of TLR-9 as compare to control, while indoxacarb (4 mg/kg) alone and in combination with LPS resulted 16.21-fold change and 29.4-fold change increase in expression of TLR-9 m-RNA, respectively, as compared to control. Similarly, indoxacarb (2 mg/kg) alone or in combination with LPS also altered TLR-9 expression. Further at protein level control group showed minimal expression of TLR-9 in lungs as compare to other groups, however, LPS group showed intense positive staining in bronchial epithelium as well as in alveolar septal cells. Indoxacarb at both doses individually showed strong immuno-positive reaction as compare to control, however when combined with LPS resulted intense staining in airway epithelium as compare to control.

Conclusion: Chronic oral administration of indoxacarb for 90 days (4 and 2 mg/kg) alters expression of TLR-9 at m-RNA and protein level and co-exposure with LPS exhibited synergistic effect.

Keywords: indoxacarb, lipopolysaccharide, lungs, mice, toll-like receptor-9.

Abstract

Canine vector-borne diseases constitute a large group of diseases transmitted by arthropods with worldwide distribution. A wide range of bacterial, viral, and parasitic agents that are transmitted by vectors cause disease to dogs, many of which can also affect humans and thus have an important zoonotic potential. Bacterial agents that are transmitted by vectors have been considered less important than viral or parasitic agents and are not commonly discussed in companion animal practice. However, close contact between pet animals and people offers favorable conditions for transmission of these bacteria. Many of these diseases have become a focus of interest for scientists in recent years. Increase in reservoir abundance, climate change, changing habitat structure, socio-political changes, and imports of dogs for welfare reasons and trade as well as traveling are considered to be potential factors for the pathogens and vectors introduction into new areas. Apart from, the veterinary aspect of these diseases, domestic dogs could play a central epidemiological role in the transmission of bacterial agents to humans, acting as reservoirs and sentinels, a circumstance that requires a One Health approach. This review highlights the most important of these bacterial agents, presenting updated current knowledge with special reference to treatment approach and One Health aspect.

Aim: Recent trends in comparative animal and human research inform us that collaborative research plays a key role in deciphering and solving cancer challenges. Globally, cancer is a devastating diagnosis with an increasing burden in both humans and dogs and ranks as the number three killer among humans in Kenya. This study aimed to provide comparative information on cancers affecting humans and dogs in Nairobi, Kenya.

Materials and Methods: Dog data collection was by cancer case finding from five veterinary clinics and two diagnostic laboratories, whereas the human dataset was from the Nairobi Cancer Registry covering the period 2002-2012. The analysis was achieved using IBM SPSS Statistics^® v.20 (Dog data) and CanReg5 (human data). The human population was estimated from the Kenya National Census, whereas the dog population was estimated from the human using a human:dog ratio of 4.1:1.

Results: A total of 15,558 human and 367 dog cancer cases were identified. In humans, females had higher cancer cases 8993 (an age-standardized rate of 179.3 per 100,000) compared to 6565 in males (122.1 per 100,000). This order was reversed in dogs where males had higher cases 198 (14.9 per 100,000) compared to 169 (17.5 per 100,000) in females. The incident cancer cases increased over the 11-year study period in both species. Common cancers affecting both humans and dogs were: Prostate (30.4, 0.8), the respiratory tract (8.3, 1.3), lymphoma (5.6, 1.4), and liver and biliary tract (6.3, 0.5), whereas, in females, they were: Breast (44.5, 3.6), lip, oral cavity, and pharynx (8.8, 0.6), liver and biliary tract (6.5, 1.2), and lymphoma (6.0, 0.6), respectively, per 100,000.

Conclusion: The commonality of some of the cancers in both humans and dogs fortifies that it may be possible to use dogs as models and sentinels in studying human cancers in Kenya and Africa. We further infer that developing joint animalhuman cancer registries and integrated cancer surveillance systems may lead to accelerated detection of the risks of cancer in Africa.

Aim: Client satisfaction gained great importance in health care as a measurement of service quality. One of the most popular methods to evaluate client satisfaction is the SERVQUAL inquiry which measures service quality by evaluating client expectations and services towards a service in five dimensions: Tangibles, Empathy, Assurance, Reliability and Responsiveness.

Materials and Methods: In order to evaluate if owners of pets with cancer constitute a distinctive group from the general pet owner population and if these differences were perceived by the hospital staff we applied a SERVQUAL questionnaire to 51 owners of pet with cancer, 68 owners from the general pet population and 14 staff members.

Results: Owners of oncologic pets had different expectations of an ideal service granting importance to Assurance questions (6.75 vs 6.5, p= 0.045) while showing unmet needs in Reliability and Empathy dimensions. Veterinarians failed to understand these specificities and over evaluated characteristics of Tangible dimension (6.75 vs 6.25, p=0.027).

Conclusion: Owners of pet with cancer seem to constitute a specific subpopulation with special needs and veterinary staff should invest resources towards Assurance instead of privileging tangible aspects of veterinary services. By aligning professionals expectations with those of pet owners veterinarians can achieve better client satisfaction, improved compliance and stronger doctor-owner relationships.

Aim: The occurrence of acute renal failure (ARF) cases continues to increase every year. Some of the cases are due to nephrotoxic effect caused by overdose of antibiotic consumption or abuse of the drug, gentamicin. An antibiotic therapy that can be used to overcome in such a case is the pomegranate extracts. However, until now, studies using pomegranate for cases of ARF have not been done. This study aims to determine changes in body weight, the levels of total protein (TP), and the levels of serum uric acid (UA) as a result of the pomegranate extract consumption.

Materials and Methods: A total number of 32 rats (Rattus norvegicus) were divided into four groups randomly. One group was assigned as the control group (P0) and given intraperitoneal (i.p.) saline and 0.3% carboxy methyl cellulose sodium (CMC) Na; P1 was provided with 80 mg/kg bw/i.p. gentamicin and 0.3% CMC Na orally, P2 was supplied with 80 mg/kg bw/i.p. gentamicin and ellagic acid in 0.3% CMC Na, and P3 was given 80 mg/kg bw/i.p. gentamicin and 150 mg/kg bw pomegranate extract in 0.3% CMC Na. The provision of treatment was carried out in 8 days and followed by making the overthrow of body weight and blood sampling for the examination of study variables.

Results: The results taken by doing the analysis of variance method for the four treatment groups show that the control group (P0) has significant differences from P1, P2, and P3 (p<0.05), but there are no significant differences among the other three treatment groups. Meanwhile, the average values of serum UA levels among P1, P2, and P3 indicate significant differences.

Conclusion: In conclusion, the administration of pomegranate extracts in the treatment of nephrotoxicity toward rats is effective to maintain normal body weight, normal TP levels, and the UA blood serum of the rats. As this study is a preventive therapy, it needs further researches about the effective dose as a curative therapy, its level of effectiveness and its long-term side effects.

Aim: Ticks are obligate ectoparasites that have an impact on wide range of vertebrates and also act as a potential vector for the transmission of tropical theileriosis, babesiosis, etc., causing significant loss to livestock production worldwide. While feeding, they introduce their saliva containing different bioactive molecules into the host. These molecules have the capability to counteract the host hemostatic mechanism to suck host blood successfully. Therefore, the study was aimed to isolate anti-platelet aggregating peptides from salivary gland extract (SGE) of Hyalomma anatolicum ticks, a commonly available tick in India.

Materials and Methods: Female H. anatolicum salivary glands were dissected out and SGE was prepared by homogenizing it in a suitable buffer under ice. Extract so obtained was fractionated by gel filtration chromatography using Sephacryl S-200 column. Total protein concentration in fractions was estimated and bovine platelets were isolated, stimulated with thrombin (positive control), treated with Gly-Pro-Arg-Pro amide (negative control) and with salivary gland fractions for identification of proteins/peptides having anti-platelet aggregating activities.

Results: Proteins/peptides present in various salivary gland fractions inhibited the bovine platelet aggregation and the percent inhibition ranged between 33% and 35.8%.

Conclusion: The results suggests that the fractions of H. anatolicum salivary glands possess thrombin-induced anti-platelet aggregating activity and which could be further exploited for raising anti-tick vaccine and also for therapeutic purpose.

Keywords: anti-platelet aggregating proteins/peptides, gel filtration chromatography, Hyalomma anatolicum salivary gland, thrombin.

Aim: To study the prevalence of antimicrobial resistance due to extended spectrum beta-lactamase (ESBL)-producing Escherichia coli in samples collected from the ceca of healthy broilers of poultry sale outlets (PSOs) Jabalpur.

Materials and Methods: A total of 400 cecal swab samples were taken randomly from freshly slaughtered poultry of 39 PSOs located at four different zones or areas of Jabalpur and were screened for the presence of ESBL-producing E. coli using standard methods. Further they were characterized phenotypically by standard methods.

Results: All the 400 samples were screened for E. coli producing ESBL enzyme. Among the samples positive for E. coli 135 were positive for ESBL E. coli giving an overall prevalence of 33.5%.

Conclusion: This study related to the prevalence of ESBL-producing E. coli in healthy broilers in Jabalpur is indicative of antibiotic resistance prevalent in the healthy birds which are used for human consumption as well. It also signifies resistance prevalent against beta-lactam antibiotics including third and fourth generations of cephalosporins.

Abstract

Dogs are the hosts for a wide helminth spectrum including tapeworms, flatworms, and nematodes. These parasites affect the dog health and cause morbidity and mortality, especially in young and old animals. Some species, as Toxocara canis, Ancylostoma caninum, Dipylidium caninum, and Echinococcus spp. are well-known zoonotic parasites worldwide, resulting in high public health risks. Poor data about canine helminth species and prevalence are available in Russia, mainly due to the absence of official guidelines for the control of dog parasites. Moreover, the consequent low quality of veterinary monitoring and use of preventive measures, the high rate of environmental contamination by dog feces and the increase of stray dog populations, make the control of the environmental contamination by dog helminths very difficult in this country. This paper reviews the knowledge on canine helminth fauna and prevalence in Russia. Practical aspects related to diagnosis, treatment, and control of parasitic diseases of dogs in Russia are discussed.
