A survey of 95 wild rats which were captured from various locations was conducted to determine the diversity and distribution of ectoparasites and endoparasites infesting wild rat population around the city of Ipoh and Kuala Lumpur. The rodents captured were Rat tus norvegicus and post mortem was carried out immediately after capture, with skin and organs examined for parasite infection. Ectoparasites recovered were blood sucking louse (Polyplax spinulosa) and mites (Myocoptes musculinus). Endoparasites recovered were nematodes (Aspiculuris tetraptera, Trichuris sp., and two strongyles, one of which is Strongyloides sp.) And three intestinal protozoan parasites (Blastocystis sp., Trichomonas sp., and a coccidia). Low diversity of ecto- and endoparasites were observed infecting wild rat population caught in Ipoh as compared to Kuala Lumpur.
Mostrar más [+] Menos [-]Accuracy of transvaginal ultrasonography for early pregnancy diagnosis in Attappady black goats Texto completo

Philip, Laiju M. | Abhilash, R. S. | Francis, Bastin P.
Transabdominal ultrasonography has been popularly used in animal reproduction for the assessment of pregnancy status and foetal viability where as transvaginal method for pregnancy diagnosis is rarely used for pregnancy diagnosis in goats. The study was conducted in 74 Attappady Black goats from Government Goat Farm, Attappady and Livestock Research Station, Thiruvizhamkunnu to evaluate the accuracy of trans-vaginal methods and to identify the fetal characteristics from day 20 to 75. Transvaginal ultrasonographic examination was performed using endocavity transducer with frequency of 6.5 to 8 MHz. Observations were made in all the pregnant does at three different stages of pregnancy i.e., 20-35 days, 35-55 days and 55-75 days. Does were diagnosed as pregnant from the observation of gestational sac, embryo or foetus, embryonic or foetal heartbeat, placentomes or foetal skeleton. Sensitivity, specificity, positive predictive value, negative predictive value and overall accuracy along gestation period were 98.03, 92.3, 96.15, 96 and 95.62%, respectively. It is concluded from the present study that transvaginal ultrasonography can be used for herd pregnancy diagnosis at early stages from day 20 to 45 of pregnancy diagnosis in goats.

Data over a period of eleven years was analysed for Infectious Bursal Disease (IBD) virus isolated from chicken samples submit ted to the Regional Veterinary Laboratory at Bukit Tengah, Malaysia (RVLBT) for diagnosis. A total of 247 suspect IBD cases were tested by Virology Section, RVLBT between years of 2006 to 2016. IBD virus has been isolated by using Agar Gel Precipitation Test (AGPT), a bursal homogenate which has been used as an antigen against a known positive antiserum. About 27 cases (11%) from a total of 247 suspect cases in chickens were positive for the presence of IBD. The rate of IBD may be influenced by age of chickens with an increase in the possibility of IBD occurring in chicken older than 3 weeks. Apart from that, both broiler and local chickens are highly susceptible to this disease. Therefore, awareness on the existing IBD cases indicates the importance of strict management procedures, proper management programmes, vaccination and immunisation for chickens in Malaysia.

Identification of microorganisms, including bacteria, are widely used especially in environmental studies, biotechnology, clinical microbiology, microbial forensics, and in research study. The conventional method of bacteria identification is based on phenotypic observation techniques by profiling an organism’s metabolic attributes or some aspect of its chemical composition. Then, interpretation of test results involves substantial subjective judgement. Currently, general 16S rRNA sequencing and specific PCR play an important role in the accurate and faster identification of bacteria. The aim of this study is to compare the identification of the genus or species of bacteria from agricultural waste using conventional microbiology biochemical test and molecular techniques PCR 16S rRNA universal amplified ribosomal region (UARR) sequencing. A total of 72 agricultural waste samples and 2 ATCC culture as positive control were tested. Out of two ATCC bacteria and fifteen bacteria isolates identified by the biochemical test, twelve species (71%) of bacteria gave exactly the same bacteria genus as the 16S rRNA sequencing results. Aeromonas hydrophilia, Alcaligenes faecalis and Acinetobacter calcoaceticus was revealed as Pseudomonas sp. from the sequencing results. As for Alcaligenes sp., the results from the sequencing is Stenotrophomonas maltophilia. Previous reports also showed different results of the same isolate which were from similar classification, and closely related to each other. The limited number of biochemical tests available in a laboratory will contribute to misidentification of a proposed specie.
Mostrar más [+] Menos [-]Ignorance as a factor influencing the prevalence of onchocerciasis in some villages in Oyo State, Nigeria Texto completo
2017
Akinboade, O. A. | Anong, C. I. N. | Uwalaka, E. C.
Most studies on Simulum damnosum in Nigeria has focused mainly on the problem of onchocerciasis from the ecological standpoint. However, this study is aimed at viewing it from the human angle, with focus placed on the ignorance of the rural dwellers about the influences of their environment on the increasing incidences of onchocerciasis in their population. The premise is that, as the government and the scientists are working towards finding a lasting solution to the epidemic, the rural dwellers need to wake up to the realities of their own destiny. They need to come out and collaborate with other good efforts to form a strong united force that will rid their society of this menace. A study on the level of ignorance was carried out. It is assumed that their ignorance has kept the villagers relatively inactive and passive about freeing themselves. A descriptive method was used for this research and about 450 villagers were randomly selected and verbally interviewed. A questionnaire was designed and used as the instrument of the research. The research was carried out in two different villages of Asejire and Asepari. Findings were encouraging. Some of the villagers did not know about the existence of the disease even when some of their close relatives showed the symptoms. This high level of ignorance shows that it will be difficult to attain any cooperation from them in any attempt to make their environment unfavourable for the vector.

Parkinson's disease (PD) is an irreversible neurological disorder with related locomotor dysfunction and is characterized by the selective loss of nigral neurons. PD can be experimentally induced by 6-hydroxydopamine (6- OHDA). It has been reported that reactive oxygen species, which deplete endogenous glutathione (GSH) levels, may play important roles in the dopaminergic cell death characteristic of PD. Fucoidan, a sulfated algal polysaccharide, exhibits anti-inflammatory and anti-oxidant actions. In this study, we investigated whether fucoidan can protect against 6-OHDA-mediated cytotoxicity in SH-SY5Y cells. Cytotoxicity was evaluated by using MTT and LDH assays. Fucoidan alleviated cell damage evoked by 6-OHDA dose-dependently. Fucoidan reduced the number of apoptotic nuclei and the extent of annexin-V-associated apoptosis, as revealed by DAPI staining and flow cytometry. Elevation of lipid peroxidation and caspase-3/7 activities induced by 6-OHDA was attenuated by fucoidan, which also protected against cytotoxicity evoked by buthionine-sulfoximine-mediated GSH depletion. Reduction in the glutathione/glutathione disulfide ratio induced by 6-OHDA was reversed by fucoidan, which also inhibited 6-OHDA-induced disruption of mitochondrial membrane potential. The results indicate that fucoidan may have protective action against 6-OHDAmediated neurotoxicity by modulating oxidative injury and apoptosis through GSH depletion.

Getah virus (GETV) infection causes sporadic outbreaks of mild febrile illness in horses and reproductive failure in pigs. In this study, we established a reverse transcription polymerase chain reaction (RT-PCR) method to detect GETV from suspected virus-infected samples. The reaction conditions were optimized and validated by using RNA extracted from GETV propagated in cell culture. A GETV-specific GED4 primer set was designed and used to amplify a 177 bp DNA fragment from a highly conserved region of the E1 glycoprotein gene in the GETV genome. RT-PCR performed with this primer set revealed high sensitivity and specificity. In the sensitivity test, the GED4 primer set detected GETV RNA at the level of 102.0 TCID50/mL. In the specificity test, the GED4 primer set amplified only a single band of PCR product on the GETV RNA template, without non-specific amplification, and exhibited no crossreactivity with other viral RNAs. These results suggest that this newly established RT-PCR method is useful for accurate identification of GETV infection in animals.

A 9-month-old intact male Maltese dog (1.52 kg) was diagnosed with a patent ductus arteriosus (PDA). Transcatheter occlusion of the PDA was performed by using the Amplatz canine duct occluder (ACDO). After occlusion, reflex bradycardia occurred and lasted for at least 15 h with normal systolic arterial pressure and slightly increased diastolic arterial pressure. The bradycardia slowly resolved, and the heart rate was normal in re-examinations after 7 and 30 days. This is the first case of reflex bradycardia after ACDO implantation, in which the bradycardia continued for a long time, even after recovery from anesthesia.

A 5-year-old, 2.7 kg, spayed female Scottish Fold cat presented with hematemesis after administration of oral zaltoprofen, a non-steroidal anti-inflammatory drug, by the owner. Diagnostic imaging and blood analyses indicated development of acute kidney injury (AKI) resulting from zaltoprofen ingestion. To correct dehydration and anemic conditions, the cat received intravenous fluid therapy with whole blood transfusion and peroral N-acetylcysteine. Clinical signs resolved, but persistent azotemia was unresolved indicating that AKI could progress to chronic kidney disease. This case suggests that although zaltoprofen may have low adverse effects on humans, administration of zaltoprofen in cats can have serious adverse effects.
