Aim: Chhotanagpuri breed of sheep reared for mutton in Jharkhand, India, having problem of low litter size and body weight. The response of genetic improvement for traits with low heritability through traditional selection method is timeconsuming. Therefore, marker-assisted selection based on a polymorphism study of suitable candidate gene can response quickly. Thus, this study was aimed at identification of different allelic and genotypic frequencies of Booroola fecundity (FecB) gene and its association with multiple birth and postnatal growth in Chhotanagpuri sheep.
Materials and Methods: DNA isolation and gene-specific amplification of FecB gene was performed from blood samples of from 92 Chhotanagpuri lambs maintained under similar feeding and  management conditions. Custom nucleotide sequencing and single-strand conformational polymorphism analysis were performed to identify different genotypes with respect to the target gene. Statistical analysis was performed for determination of allelic and genotypic frequencies of FecB gene polymorphisms and its association with multiple birth and postnatal growth of lambs from birth to 52 weeks age.
Results: “AA” “AB” and “BB” genotypes were found at locus-1 as it is polymorphic for FecB gene while locus-2 was found to be monomorphic for FecBgene. Higher frequency of “A” allele at locus-1 was found in single born lambs, whereas “B” allele was predominant among multiple born lambs. The lambs having “BB” genotype weighed significantly (p≤0.01) heavier than those of “AB” and “AA” genotype at 52 weeks of age.
Conclusion: “BB” genotype has emerged as favored genotype for multiple births and better growth indicator. Therefore, homozygous lambs for “B” allele should be selected and utilized in breeding program for better growth rate.

Research (Published online: 23-11-2016)
20. Value added by Spirulina platensis in two different diets on growth performance, gut microbiota, and meat quality of Japanese quails -Mohamed S. Yusuf, Marwa A. Hassan, Mohamed M. Abdel-Daim, Adel S. El nabtiti, Ali Meawad Ahmed, Sherief A. Moawed, Ahmed Kamel El-Sayed and Hengmi Cui
Veterinary World, 9(11): 1287-1293



   doi: 10.14202/vetworld.2016.1287-1293


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.

  doi: 10.14202/IJOH.2016.69-74


Abstract

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.
Keywords: antimicrobial resistance, Escherichia coli, extended spectrum beta lactamase, Klebsiella pneumoniae, nosocomial infections.

   doi: 10.14202/vetworld.2016.1282-1286



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.

Bacterial canine vector-borne zoonotic diseases in “One Health” concept

Review (Published online: 20-11-2016)
9Bacterial canine vector-borne zoonotic diseases in “One Health” concept - George Valiakos
International Journal of One Health, 2: 58-68



  doi: 10.14202/IJOH.2016.58-68


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.

Research (Published online: 19-11-2016)
8. One Health and cancer: A comparative study of human and canine cancers in Nairobi - Nyariaro Kelvin Momanyi, Rugutt Anne Korir and Riungu Erastus Mutiga
International Journal of One Health, 2: 42-57



  doi: 10.14202/IJOH.2016.42-57


Abstract

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.

Comparison of veterinary health services expectations and perceptions between oncologic pet owners, non-oncologic pet owners and veterinary staff using the SERVQUAL methodology

Research (Published online: 18-11-2016)
18. Comparison of veterinary health services expectations and perceptions between oncologic pet owners, non-oncologic pet owners and veterinary staff using the SERVQUAL methodology - Hugo Gregório, Patricia Santos, Isabel Pires, Justina Prada and Felisbina Luísa Queiroga
Veterinary World, 9(11): 1275-1281



   doi: 10.14202/vetworld.2016.1275-1281



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.
