Serum acute phase proteins in cows with SARA (Subacute Ruminal Acidosis) suspect

The aim of this study was to evaluate the variations of Acute Phase Proteins (APPs) and other blood constituents during the onset of the sub-acute ruminal acidosis (SARA) pathological status. A total of 108 cows from 12 dairy herds were randomly selected and divided into three Groups of 36 animals each. All animals were subjected to a rumenocentesis. Group A was composed by subjects with a rumen pH>5.8, Group B was composed by subjects with a rumen pH ≤5.5≤5.8 and Group C was composed by subjects with a rumen pH<5.5. Blood samples were collected by jugular venipuncture and Haptoglobin (Hp), Serum Amyloid A (SAA), Total Proteins, Albumin and White Blood Cells (WBC) were determined. One-way ANOVA showed a statistical significance on Rumen pH, Hp, SAA. SARA seems not stimulate the APPs production from liver

Prognostic Factors and a Prognostic Index for Cats with Acute Kidney Injury

Background The clinical manifestations of acute kidney injury (AKI) range from mild to fatal in cats; however, prognosis factors have been rarely studied. Hypothesis/Objectives To find the clinical factors significantly correlated with the outcome among cats with AKI and to develop a simple prognostic index. Animals Seventy cats with AKI were recruited. Methods Demographic and clinicopathological data obtained from 70 cats with AKI were retrospectively collected. Student's t-test or MannWhitney U-test and Pearson chi-square test or Fisher's exact were applied to determine the factors associated with survival in cats with AKI. Using logistic regression, the statistically significant factors associated with prognosis were identified and a new prediction model was generated. Results The overall case fatality rate was 64% (45/70). The results showed that nonsurviving cats had significantly lower levels of PCV, WBC, RBC, LDH and albumin, a lower albumin/globulin ratio, lower blood glucose, and a reduced body temperature, as well as being older. Serum urea and creatinine concentrations were not statistically significant as prognostic factors, but a decrease in these 2 variables in 3 similar to days was significantly related to a reduction in death. A summary prognostic index including body temperature and LDH and albumin concentrations had area under the receiver-operating characteristic curve (AUROC) for predicting death of 0.86 (P similar to<similar to.05) and a cut-off value of 0.82, a sensitivity of 77% and a specificity of 90%. Conclusions The prognosis in cats with AKI is quite different from that found for human and dogs

Phylogenetic analysis of canine parvovirus VP2 gene in Taiwan

Canine parvovirus ( CPV) is a non-enveloped virus with a single-stranded DNA genome and causes infectious enteritis in dog. In this study, 36 isolates of CPV infection were obtained in Taichung, Taiwan from 2003 to 2004. Using primers that can distinguish subtypes of CPV, we amplified part of viral VP2 gene by polymerase chain reaction (PCR) and the PCR product was sequenced; results demonstrated that two isolates could be classified as type 2a of CPV and the others were type 2b. The complete coding region of VP2 gene of type 2b was also sequenced, and phylogenetic analysis of these DNA sequences revealed that our Taichung isolate was close to the V-120, FPV-314, 97-008, Taiwan 9, LCPV-T1, and T4 isolates; however, because of the degeneracy of codons, the amino acid sequences of Taichung isolate was similar to that of the 97-008 isolate from Japan. It is known that two important amino acid residues (Asn-426 in type 2a and Asp-426 in type 2b; Ile-555 in type 2a and Val-555 in type 2b) are the determinants for the discrimination of type 2a or type 2b. After scrutinizing the complete VP2 gene of our Taichung isolate, we found the VP2 protein of the Taichung isolate did possess this molecular feature of type 2b virus. Previous studies reported that type 2a virus was the major type in Taiwan; our finding showed that CPV type 2b was the predominant type in the middle part of Taiwan. Moreover, a unique Ala-489 in VP2 of our Taichung isolate was found, contrasting to a Val-489 in the VP2 of other strains

Disseminated Abscessation Complicated with Bone Marrow Abscess Caused by Arcanobacterium pyogenes in a Goat

An 8-month-old, Nubian wether with a history of systemic illness was euthanatized for a pathological examination. At necropsy, the presence of disseminated abscessation and cellulitis in the limbs was noted. Other postmortem findings associated with the visceral disease in this animal included multiple abscess lesions, mainly in the lungs, kidneys, phalanxes and vertebrae. Histopathological logically, lesions of arteriolitis were found as evidenced by bacterial embolisms in pulmonary and renal arteriola, indicating a bacteremia in the patient. Arcanobacterium pyogenes was consistently isolated from 8 lesions of abscessations, including the lesions of subcutaneous abscesses as well as bone marrow abscess in phalanxes and thoracic vertebrae. This is the first published report of disseminated arcanobacterial infection with bone marrow abscess of both the phalanxes and vertebrae in goat

Dystocia in Formosan sambar deer (Cervus unicolor swinhoei) in semi-domesticated herds

Over a nine-year period (2000 to 2008), 22 instances of dystocia and 50 normal fawnings in Formosan sambar deer (Cervus unicolor swinhoei) hinds from semi-domesticated herds were investigated. The majority of the hinds (17, 77.3 per cent) that suffered dystocia were categorised as having a body condition score (BCS) in the medium range (between 2.5 and 3.5 inclusive), indicating that there was no significant relationship between obesity (BCS >3.5) in hinds and the occurrence of dystocia. In addition, maternal body condition had no effect on the birthweight of the offspring. Among the 22 instances of dystocia, 16 of the fawns (72.7 per cent) did not survive; one of these deaths was anteparturient and the other 15 were parturient. Eighteen (81.8 per cent) of the cases of dystocia involved male fawns, and 15 (93.8 per cent) of the deaths were of male fawns (P=0.044). Nine (40.9 per cent) of the instances of dystocia resulted from maternal excitement, mainly attributable to disturbances caused by human beings. In 12 of the cases that resulted in the death of the fawn, the request for veterinary assistance had been delayed at least one day. There were six cases in which the fawns survived; these were the ones that had received assistance within six hours after the onset of parturition

Serum haptoglobin concentration in cattle

To obtain a basal concentration of serum Haptoglobin (Hp) in cattle in Taiwan, Hp concentrations were measured from serum samples collected from 10 healthy heifers, every week for one year. The values were also compared with those collected from 15 cows diagnosed with postpartum metritis. The heifers were successfully impregnated by artificial insemination six months after the tests. Hp concentrations were also measured in the serum collected from 11 other cows within 3 weeks after parturition. The Hp assay developed in this study gave a good correlation (r=0.893)with Western blotting. The Hp concentration of 454 serum samples from the 10 heifers had a mean value of 83.6 +/- 34.1 mg/l, and there was no significant difference among individual heifers. The basal value of Hp in heifers was calculated as less than 73.6 mg/l. No significant difference in Hp concentration was observed among the 10 heifers during cold and warm seasons (19.8 +/- 2.2degreesC vs 27.3 +/- 1.4degreesC), or before and after pregnancy. The mean serum Hp concentration from cows suffering from postpartum reproductive disorders was 1133.5 +/- 627.1 mg/l, which was significantly greater than the serum of healthy heifers and postpartum cows (104.6 +/- 61.0 mg/l) (P<0.05). These results demonstrate that Hp concentration may be a useful indicator for cows with postpartum reproductive disorders

Jejunojejunal intussusception and colonic impaction in a 12-day-old orphan foal

A 12-day-old 14.4-kg, female foal of Australian Miniature Pony breed was presented at the National Chung Hsing University Veterinary Medicine Teaching Hospital. Taiwan, with a history of weakness of 2 days duration. The mare died of unknown cause on the previous day. Abnormal findings during physical examination included an estimated dehydration of 3 to 5%, dark red oral mucous membranse, elevated heart, and respiratory rates, stiffened feces, and absence of intestinal motility on ausculation. Continual nursing care was followed by intravenous fluid therapy and nonsteroidal anti-inflammatory drug and antibiotic treatment. The foal's condition deteriorated rapidly, and feeding was refused. Subsequently, she developed signs of pyrexia and panting. In spite of oxygen supplement, she died 18 hours after admission. Postmortem examination revealed the presence of a jejunojejunal intussusception, 20 cm in length, a torsion of jejunum proximal to the intussusception also was noted. An ulcerative lesion, 3 cm in diameter, was found on the mucosa of duodenum. Large amounts of sand, coat hair, and hay mantling in bloody discharge were observed in a colonic impaction. That it was an acute case was evident by the involvement of intussusception and ulceration, indicating desquamation of the necrotic epithelial cells with edema and distinct infiltration of neutrophils. These results suggested that a practical management strategy for nursing an orphan foal should be performed to avoid a similar case in the future
