ABSTRACT

Aim: The objective of this research was understanding slaughterhouses sustainability and the prospection status in special region of Jakarta Province Indonesia.

Materials and Methods: The concept of sustainable slaughterhouse was formed based on social, economy, ecology, technology, and institutional dimension. Research objects were three types of slaughterhouses in Special Capital Region of Jakarta Indonesia; pig slaughterhouse, chicken slaughterhouse, and ruminant slaughterhouse. Tools used were questionnaires to assess the perception of people living around slaughterhouses, assessment of the knowledge, attitude, and practice from slaughterhouse management, along with assessment and focus group discussion for sustainability test. Methods used were descriptive analysis and sustainability test by multidimensional scaling method. Data collected consisted of primary and secondary data. Primary data were obtained by field survey, interview, questionnaire, measurement of the waste threshold, and microbe contamination, whereas secondary data were obtained from slaughterhouse agency. Data were analyzed with IBM statistical package for the social sciences (SPSS®) version 18 to calculate characteristic, variables correlation, sustainability test with Rapfish® modified into Rap slaughterhouse, and prospective analysis with PPA.

Results: The level of sustainability for pig slaughterhouse was moderately sustainable with 0.5173 index value, ruminant slaughterhouse was moderately sustainable with 0.5171 index value, and chicken slaughterhouse was moderately unsustainable with 0.4530 index value.

Conclusion: Scenario on policies that should be applied in ruminant slaughterhouse was increasing the use of waste as biogas; for chicken slaughterhouse was increasing promotion and for pig slaughterhouse was increasing product quality control. The implication of this research was to provide input based on a scientific study for the local government of Jakarta in managing the slaughterhouses.

ABSTRACT

Aim: Genus Anaplasma is of veterinary and public health importance, and its members utilize ruminants as key hosts in their epidemiology. To date, information about the occurrence and molecular identity of Anaplasma phagocytophilum and other Anaplasma species in Saudi Arabian goats is scarce. This study aimed to molecularly detect and characterize zoonotic A. phagocytophilum and other Anaplasma spp. in goats from Taif District, KSA.

Materials and Methods: Blood samples collected from 67 goats were polymerase chain reaction tested using common and A. phagocytophilum-specific primers targeting 16S rRNA and msp4 genes, respectively. Amplicons of common reactions were purified, sequenced, and analyzed.

Results: Six goats yielded positive results with common primers, whereas all animals proved negative for A. phagocytophilum. Analysis of the two successfully sequenced amplicons revealed the presence of a variant strain of Anaplasma ovis (99.52% ID) and a new Anaplasma organism, which was clustered with Anaplasma bovis (95.9% ID) and Aegyptianella pullorum (94.99% ID) and distinctly separated from all other recognized species of the genus Anaplasma.

Conclusion: The tested goats proved negative for A. phagocytophilum; however, we could not confirm that the area is pathogen free. A variant strain of A. ovis and a putative novel Anaplasma spp. were reported raising the concern of veterinary and zoonotic potential. Other genes should be sequenced and analyzed for complete identification of the detected organisms.

ABSTRACT

Background and Aim: Zoonotic rodents (Rodentia: Muridae: Gerbillinae) and Phlebotominae sand flies are the major reservoir hosts and vectors of Leishmania major causing zoonotic cutaneous leishmaniasis, respectively. This study was carried out to evaluate the epidemiological aspects of cutaneous leishmaniasis (CL) in Tangestan County, Southwest Iran.

Materials and Methods: This descriptive cross-sectional study was carried out on human cases, probable reservoirs, and vectors of CL at Tangestan County in 2017. The data of patients were taken on health centers and analyzed. To determination faunistic of sand flies, they were collected using sticky paper traps and identified using identification keys. The rodent samples were captured using Sherman live traps and determined for amastigote infection.

Results: A total of 436 cases occurred during 2005-2017 and the incidence rate of disease was 0.2-12/100,000 people. Six species of sand flies including three species of Phlebotomus and three species of Sergentomyiaincluding Phlebotomus papatasi, Phlebotomus sergenti, Phlebotomus alexandri, Sergentomyia tiberiadis, Sergentomyia baghdadis, and Sergentomyia clydei were identified. From 185 trapped rodents, 9 species were identified. We founded, 2 out of 132 Tatera indica (1.53%) were positive with Leishmania spp. using the microscopic method.

Conclusion: According to the existence of human leishmaniasis cases as a host, T. indica with high abundance and infected to Leishmania as a reservoir, and existence of P. papatasi with high abundance as a suspected vector of disease; there is a potential for transmission of disease in the area. Design of exact control and prevention strategies is highly recommended.

ABSTRACT

Aim: The present study was aimed to determine the normal reference values of M-mode echocardiographic measurements in healthy Indian Spitz dogs and evaluate the influence of gender and body weight on these measurements.

Materials and Methods: M-mode echocardiography was performed in twenty-four clinically healthy conscious Indian Spitz dogs, aged 3-5 years and weighing 7-18 kg. Measurements were made from the right parasternal long axis left ventricular outflow tract view of the heart. The parameters recorded were: Left ventricular internal dimension, interventricular septal thickness and left ventricular posterior wall thickness during diastole and systole, left atrial diameter, aortic root diameter, left ventricular systolic functional parameters, and indices and mitral valve parameters.

Results: M-mode echocardiographic measurements in healthy Indian Spitz dogs were standardized. Gender had no influence on echocardiographic measurements except mitral valve excursion amplitude and time interval between onset and end of mitral valve closure, which were significantly (p<0.05) higher in females than males. Left ventricular internal dimension at end-diastole, left ventricular internal dimension at end-systole, left ventricular posterior wall dimension at end-systole, end-diastolic volume, end-systolic volume, stroke volume, cardiac output, left ventricular ejection time, and mitral valve excursion amplitude correlated significantly (p<0.05) with body weight in Indian Spitz dogs.

Conclusion: Data obtained in the present study can be used as breed-specific reference values for cardiac disease diagnosis as well as for future studies in Indian Spitz dogs.

ABSTRACT

Background and Aim: For many years, people use natural products from the plant and fungal to improve immune response against microorganism. This study aimed to investigate the immunomodulatory properties of polysaccharides (PS) from Coriolus versicolor in mice infected by intracellular bacteria Neisseria gonorrhoeae.

Materials and Methods: Thirty-six female BALB/C mice were divided into six groups: Normal control, negative control, positive control, P1 (PS before infection), P2 (PS after infection), and P3 (PS before and after infection). PS were administrated for 10 days. N. gonorrhoeae was infected twice with 2 weeks gap from the first to second exposure with a dose of 106 cells. 1 week after the end of treatment, level of oxidants, innate immune responses, and adaptive immune responses were measured.

Results: This study showed that PS administration could restore the number of leukocytes as normal but could not enhance the number of phagocytes and its activity. PS administration also showed immunosuppression activity by lowering nitric oxide levels in P2 and P3 groups (p<0.05). This result showed that PS prevent over-expression of pro-inflammatory cytokines by decreasing phagocytic activity. Contrast with innate immune response result; PS administration could significantly increase interferon-gamma level in P1, P2, and P3 groups (p<0.05). Level of antibodies was significantly increased in the P3 group (p<0.05). PS administration also showed an increased level of tumor necrosis factor-a, but the difference was not significant (p>0.05).

Conclusion: PS enhance adaptive immunity due to the capability of N. gonorrhoeae that able to survive and replicate in phagocytes. Thus, PS from C. versicolor could be potentially be used as a natural immunomodulator against intracellular bacteria.

ABSTRACT

Aims: Cryptosporidiosis is an important zoonotic disease of major public and veterinary concern. The disease affects humans and a variety of animal species including the domestic dog. This study aimed to determine the prevalence and risk factors associated with Cryptosporidium spp. infection in local breed of dogs from different homes and those presented at veterinary hospitals and clinics in Enugu State, Nigeria.

Materials and Methods: A total of 203 fresh fecal samples were collected from domestic dogs in six local government areas in Enugu State from February 2015 to August 2015. All the samples were examined using the formol-ether sedimentation method. Fecal smears were then stained by the modified Ziehl-Neelsen technique and examined under direct light microscopy.

Results: A total of 74 (36.5%) dogs were infected with Cryptosporidium spp. oocysts. There was a strong association (p<0.05) between the presence of Cryptosporidium spp. oocysts and management practices. However, there was no statistically significant association (p>0.05) between the presence of Cryptosporidium spp. oocysts and age, sex, and fecal consistency.

Conclusion: The findings of this work suggest that domestic dogs in Enugu State harbor and shed Cryptosporidium spp. oocysts in the environment, especially those managed semi-intensively. Such fecal shedding is particularly so and of greater zoonotic and epidemiological importance in animals that do not show clinical signs and therefore not treated. They, therefore, pose a greater public health risk, especially to immune-compromised humans and animals. Public education on the zoonotic implication of this protozoan infection is of paramount importance in Enugu State, in particular, and Nigeria, in general, considering the closeness of dogs and man.

ABSTRACT

Background and Aim: Several molecular studies on rabies virus (RABV) have been conducted in Indonesia, but it does not give clear information about molecular characteristics of previous RABV isolate in Indonesia. This study was conducted to know the characteristic of circulating RABV to determine a suitable method to control the spreading of RABV in Indonesia.

Materials and Methods: Samples of infected RABV from dog brain were collected from Sumatera, Kalimantan, Sulawesi, and Bali Islands. All samples were examined based on nucleoprotein encoding gene to determine the molecular characteristics based on homology and phylogenetic tree compared to Pasteur Virus and RABV that came from another country within Asia (Indonesia, China, Thailand, India, and Korea). The collected samples were processed by one-step reverse transcriptase-polymerase chain reaction using nucleoprotein encoding gene followed by sequencing. The amino acid of its antigenic site of isolated RABV was also analyzed.

Results: The results showed that isolated RABV has 84-85% similarity compared to Pasteur. According to phylogenetic construction, isolated samples do not share the same lineage toward Pasteur. The homology scores of isolated samples compared to RABV within Asia such as Indonesia, China, Thailand, India, and Korea were 98-99%, 92-93%, 88-89%, 86-88%, and 85-88%, respectively. According to antigenic site analysis compared to Pasteur, it was found that there were amino acid mutations within antigenic Site IV of nucleoprotein. Amino acid mutation from isoleucine to valine occurred in amino acid number 240 of 6 Kalimantan, 7 Kalimantan, and 8 Kalimantan. Amino acid mutation from alanine to aspartate and asparagine to threonine occurred within the same antigenic site in amino acid number 246 and 273 of C4 isolate from Sulawesi.

Conclusion: According to homology and phylogenetic tree analyses, isolated RABV remained different compared to RABV within Asia and Pasteur. The amino acid mutation occurred in antigenic site of nucleoprotein encoding gene.
