This is a case report ofa captive female green peafowl (Pavomuticus) that was presented with severescaly legs with raised encrusted scaleson both legs. Diagnosis of scaly leg mitewas made based on history, clinical signs,and results of parasitological examinationfrom deep skin scrapping from the areaof lesions and response to treatment.Treatment consisted of Ivermectinsolution, administered orally at a doserate of 0.2 mg/kg. The gross lesionswere completely resolved 28 days posttreatment. It was concluded that based onthe treatment given, knemidocoptiasis orscaly leg can be successfully controlledwith good prognosis in captive birds. Careshould be taken as the mite is transmittedfrom bird to bird through prolonged closeor direct contact.

Trypanosomiasis positive cases were reported in Sahom Farm Retreatin Gopeng, Perak; with multispecies livestock animals. Nzi and Vavoua traps were applied to survey the population of biting flies; stable flies (Muscidae: Stomoxyinae) and horse flies (Tabanidae)as the vector for surra. Results indicated the presence of Trypanosomiasis infection diagnosed by buffy coat examination, thinblood stained smears and serological test (Surra Sero K-Set test) and identification of its insect vectors. The presence of bothbiting flies provides the missing link between the occurrence of the disease and host or environmental factors precipitatingthe disease. Besides trypanosomiasis in cattle, other parasitic infections were also recorded with heavy infections for liver fluke (Fasciola gigantica ova) and coccidia oocysts. Therefore, some control measures are recommended to eradicate the vectors and to treat infected animals in order to prevent the dissemination ofthe trypanosmiasis.

In Malaysia there are public opinion that goat meat contributes to high blood pressure and high blood cholesterol level that can lead to cardiovascular diseases. The aim of this study was to investigate this perception. 10 subjects were involved in the study, five men and five women. They were given fixed amount of goat meat soup with two slices of bread and a cup of sugarless barley drink. Pairedsamplest-test was used to compare the differences in the subjects’ blood pressure and cholesterol level between pre- and post- intake of goat meat. The results of this study shows that consumption of goatmeat does not cause increase risk of blood pressure and cholesterol level.

Brucellosis in goats is mainly caused by the bacterium Brucellamelitensis, which is one of the most important pathogenic species in the world. In Malaysia, the annual prevalence data of brucellosis was recorded in goats and the control strategy of the disease basedon test and cull of infected animals. This strategy has caused huge economic losses to farmers and government alike. Therefore, whole genome sequencing of B. melitensis local strain is essential forimproving the current vaccine. B. melitensis strain VRI 6530/11 wasobtained from veterinary research institute biobank, Ipoh. The strain was submitted for classical identification procedures and the total genomic DNA was extracted by using DNeasy blood and tissue kit(QIAGEN). The concentration and purity of DNA were determined by using agarose gel electrophoresis and spectrophotometer (DNA/RNA) assay respectively. The genome was sequenced by using IlluminaHiSeq platform with insert size ~200 bp. A total of 1.0 Gb data was generated from the sample. More than 95% of sequencing data was retained in the sample after quality filtering, this indicatethe sequencing reads are of high quality. Final assembly had 33 scaffolds with total size ~3.28 Mb, 44 contigs, GC content is 57.25%, N50 is 293,291. A total of 3,238 protein coding genes, 48 tRNAs and 3rRNAs were predicted and over 87% of the genes were functionally annotated. Genome sequencing of a local B. melitensis strain is the first of its kind in Malaysia and work from this study can contribute towards the development of a new effective vaccine for the control ofthe disease in the country.

Inclusion body hepatitis (IBH) has been reported in many countriesin the world. The IBH characterized presence of intra-nuclear inclusion bodies in hepatocytes in chickens. On December 2015, an onset of high acute mortality in a flock of 12, 18 and 23- day-old broiler chickens in Malacca and Johore was reported to the RegionalVeterinary Laboratory, Johor Bahru, Peninsular Malaysia. The birds showed lethargy, huddling, ruffled feathers, and inappetence. At necropsy, the livers were enlarged, pale yellow, friable andwith multiple petechial hemorrhages, the kidney were congested and enlarged, with hydropericardium and gizzard erosion. Large eosinophilic intranuclear inclusion bodies were seen in hepatocytes. PCR revealed liver were positive of FAdV at expected band of 1219 bp and the nucleotide sequence share 95-99% identity with the fowl adenovirus species E, serotype 8b. Based on the acute high mortality, age of the broilers, gross and microscopic lesions (especially intranuclear inclusion bodies) and molecular finding, the condition was diagnosed as adenovirus inclusion body hepatitis.

Hung, Germaine C. | Gaunt, Casey | Rubin, Joseph E. | Starrak, Gregory S. | Sakals, Sherisse A.
OBJECTIVE To quantify and characterize pleural fluid collected from healthy dogs after placement of a thoracostomy tube (TT). ANIMALS 8 healthy Coonhound-cross dogs (mean ± SD weight, 27.2 ± 1.6 kg). PROCEDURES Thoracic CT of each dog was performed before placement of a TT and daily thereafter for 7 days. Thoracic fluid volume was calculated from CT images. Effusion was aspirated when detected; volume was recorded, and cytologic analysis and bacterial culture were performed. RESULTS Mean ± SD volume of pleural effusion detected by CT was 1.43 ± 0.59 mL/kg (range, 0.12 to 3.32 mL/kg). Mean volume collected via aspiration was 0.48 ± 0.84 mL/kg (range, 0 to 2.16 mL/kg). Cytologic analysis yielded results consistent with an exudate, characterized by septic suppurative inflammation in 6 dogs and mixed inflammation in 1 dog; there was insufficient volume for analysis in 1 dog. Sufficient volume was obtained for bacterial culture for 6 dogs, which yielded pure growths of Staphylococcus pseudintermedius (n = 3) and Streptococcus equi subspecies zooepidemicus (2) and mixed growth of both of these species (1). The TT was removed before day 7 in 4 dogs because of pyothorax (n = 3) and irreversible damage to the TT (1). CONCLUSIONS AND CLINICAL RELEVANCE Presence of a TT induced a minimal volume of pleural effusion in healthy dogs. Pyothorax developed in most dogs between 4 and 6 days after TT placement. On the basis of these findings, a TT should be removed by the fourth day after placement, unless complications are detected sooner.

Regier, Penny J. | Smeak, Daniel D. | McGilvray, Kirk C.
OBJECTIVE To compare security of continuous intradermal suture lines closed by use of barbed suture with 3 end-pass configurations or without an end-pass configuration. SAMPLE 40 full-thickness, 4-cm-long, parasagittal wounds in canine cadavers. PROCEDURES Each continuous intradermal closure was terminated with 1 of 3 end-pass techniques or without an end-pass configuration (control group). A servohydraulic machine applied tensile load perpendicular to the long axis of the suture line. A load-displacement curve was generated for each sample; maximum load, displacement, stiffness, mode of construct failure, and load at first suture slippage at termination (ie, terminal end of the suture line) were recorded. RESULTS Values for maximum load, displacement, and stiffness did not differ significantly among the 3 end-pass techniques, and load at first suture slippage at termination was not significantly different among the 4 groups. A 1-pass technique slipped in 5 of 9 samples; 3 of these 5 slips caused failure of wound closure. A 2-pass technique slipped in 3 of 9 samples, none of which caused failure of wound closure. Another 2-pass technique slipped in 4 of 10 samples; 2 of these 4 slips caused failure of wound closure. The control group had slippage in 10 of 10 samples; 9 of 10 slips caused failure of wound closure CONCLUSIONS AND CLINICAL RELEVANCE An end-pass anchor was necessary to terminate a continuous intradermal suture line, and all 3 end-pass anchor techniques were suitable to prevent wound disruption. The 2-pass technique for which none of the suture slippages caused wound closure failure provided the most reliable configuration.

Streptococcus suis is an emerging zoonotic pathogen that causes septicemia, meningitis, arthritis, and pneumonia in swine and humans. The present study aimed to characterize the genetic diversity of S. suis serotype 2 isolated from pigs showing signs of illness in Brazil using pulsed-field gel electrophoresis (PFGE), single-enzyme amplified fragment length polymorphism (SE-AFLP), and profiling of virulence-associated markers. A total of 110 isolates were studied, 62.7% of which were isolated from the central nervous system and 19.1% from the respiratory tract. Eight genotypes were obtained from the combination of virulence genes, with 43.6% and 5.5% frequencies for the mrp (+) /epf (+) /sly (+) and mrp (-) /epf (-) /sly (-) genotypes, respectively. The presence of isolates with epf gene variation with higher molecular weight also appears to be a characteristic of Brazilian S. suis serotype 2. The PFGE and SE-AFLP were able to type all isolates and, although they presented a slight tendency to cluster according to state and year of isolation, it was also evident the grouping of different herds in the same PFGE subtype and the existence of isolates originated from the same herd classified into distinct subtypes. No further correlation between the isolation sites and mrp/epf/sly genotypes was observed.

Yunik, Matthew E. M. | Galloway, Terry D. | Lindsay, L Robbin
Bovine anaplasmosis is the disease caused by the bacterium Anaplasma marginale. It can cause production loss and death in cattle and bison. This was a reportable disease in Canada until April 2014. Before then, infected herds were quarantined and culled, removing infected animals. In North America, A. marginale is biologically vectored by hard ticks (Acari: Ixodidae), Dermacentor variabilis and D. andersoni. Biting flies, particularly horse flies (Diptera: Tabanidae), can also act as mechanical vectors. An outbreak of bovine anaplasmosis, consisting of 14 herds, was detected in southern Manitoba in 2008. This outbreak lasted multiple rounds of testing and culling before eradication in 2011, suggesting local maintenance of the pathogen was occurring. We applied novel approaches to examine the vector ecology of this disease in this region. We did not detect A. marginale by screening of 2056 D. variabilis (2011 and 2012) and 520 horse flies (2011) using polymerase chain reaction (PCR).

Reagan, Jennifer K. | Selmic, Laura E. | Garrett, Laura D. | Singh, Kuldeep
OBJECTIVE To evaluate effects of anatomic location, histologic processing, and sample size on shrinkage of excised canine skin samples. SAMPLE Skin samples from 15 canine cadavers. PROCEDURES Elliptical samples of the skin, underlying subcutaneous fat, and muscle fascia were collected from the head, hind limb, and lumbar region of each cadaver. Two samples (10 mm and 30 mm) were collected at each anatomic location of each cadaver (one from the left side and the other from the right side). Measurements of length, width, depth, and surface area were collected prior to excision (P1) and after fixation in neutral-buffered 10% formalin for 24 to 48 hours (P2). Length and width were also measured after histologic processing (P3). RESULTS Length and width decreased significantly at all anatomic locations and for both sample sizes at each processing stage. Hind limb samples had the greatest decrease in length, compared with results for samples obtained from other locations, across all processing stages for both sample sizes. The 30-mm samples had a greater percentage change in length and width between P1 and P2 than did the 10-mm samples. Histologic processing (P2 to P3) had a greater effect on the percentage shrinkage of 10-mm samples. For all locations and both sample sizes, percentage change between P1 and P3 ranged from 24.0% to 37.7% for length and 18.0% to 22.8% for width. CONCLUSIONS AND CLINICAL RELEVANCE Histologic processing, anatomic location, and sample size affected the degree of shrinkage of a canine skin sample from excision to histologic assessment.
