Caseous lymphadenitis (CLA) is a chronic and contagious disease of sheep and goats caused by Corynebacterium (C.) pseudotuberculosis. A four-year-old female Saanen dairy goat was submitted to the Animal Disease Diagnostic Center at National Veterinary Research and Quarantine Service. The clinical signs of the goat were emaciation, abortion and quadriplegia. The multifocal nodules of lymph nodes were encapsulated and filled with whitish caseous contents on the cut surface. Histopathologically, lymph nodes displayed suppurative and necrotizing granulomas. Caseous necrosis was diffusely observed in the center of the lymph nodes. Gram positive bacilli were shown in the lesions. C. pseudotuberculosis was isolated and confirmed by the biochemical tests and PCR assay. Based on clinical signs, histopathological examination and bacterial isolation, we diagnosed this case as CLA. To our knowledge, this is the first report of CLA in a Saanen dairy goat in Korea.

The mRNA from distal ileum of Indian goat was cloned and characterized after purification. cDNA was synthesized using goat ileal epithelial RNA, omniscript and sensiscript reverse transcriptase and amplified by Hotstart Taq DNA polymerase with primers designed by taking conserved regions of cattle enteric _Ò-defensin, cattle lingual antimicrobial peptide(LAP) and goat _Ò-defensin-2 sequences. The amplified cDNA of 253bp was, ligated to linearised TA cloning vector and transformed into XLblue strain of E.coli which was grown overnight at 37oC in a LB plate containing ampicillin, IPTG and X-Gal. The recombinant plasmid was isolated and digested with NcoI. The white colonies showed a release of 253bp insert. The sequence analysis showed 26, 16 and 5-nucleotide substitution having 85.6%, 91.3%, 97.4% homology with reported cattle EBD, buffalo EBD and goat BD2 mRNA respectively. The deduced amino acid sequence encodes for a 64 amino acid precursor peptide showing 12,18 and 4 amino acid substitution having 80%, 70.8%, 93.8% homology with buffalo EBD, cattle EBD and goat BD2 peptide respectively. Both nucleotide and amino acid sequence homology showed that the cloned sequence was closer to goat BD2.

The effect of addition of Melia azedarach (fruit), Pimpinella anisum (seed), Cuminum cyminum linn (seed), Murraya koenigii (leaves), Emblica officinalis (fruit), Allium sativum linn (bulb), Terminalia arjuna (bark), Sapindus trifoliatus (seed), Zingiber officinale (rhizome), Trigonella foenun-graecum (seed) at three dose level (1.5%, 2.0% and 3.0% of DM) on pH, dry matter and organic matter digestibility of feed was studied with rumen liquor of goat. There was no significant change in the in vitro fluid pH, showing no adverse effect of herb addition. The addition of all the herbs at 1.5% level had no significant (P 0.05) effect on in vitro dry matter and organic matter digestibility. There was slight improvement in dry matter and organic matter digestibility with the addition of Trigonella foenungraecum at 2% level as compared to control. At 3% level of addition of this herb, there was significant (P 0.05) increase in the in vitro dry matter digestibility (%) with Trigonella foenun-graecum (51.97) as compared to control (43.95). Similarly there was significant (P 0.05) increase in the in vitro organic matter digestibility (%) with Trigonella foenun-graecum (54.95) as compared to control (46.87) having with no addition of herbs. So Trigonella foenun-graecum (seed) at 3% dose level can be further explored in in vivo experiment to utilize it as a feed additive to increase the digestibility of feed in goats.

Thirty Staphylococcus aureus isolates used in the study obtained from cattle (20) and goat (10) were haemolytic on blood agar. Twenty one of the isolates (14 from cattle, 7 from goats) produced a-haemolysis, 3 produced b-haemolysis (2 from cattle and 1 from goats), and 6 isolates (4 from cattle and 2 from goats) produced both a- and b-haemolysis. The haemolysins tested against erythrocytes from rabbit, cattle and horse in order to demonstrate a-, b- and d-toxins, respectively revealed that a- and b-toxins were produced by all the isolates but b toxin was produced by only 7 isolates from cattle and by 3 from goats. On titration it was recorded that highest titre was recorded for a-toxins (for cattle, 1:2560 and for goat, 1:1280) whereas the highest titres for b and d-toxins was similar (1:160) for cattle as well as goat isolates. The result obtained for qualitative and quantitative haemolysin assays correlated well with the haemolysis pattern seen on the blood agar plates.

The efficacy of two methods of spraying of acaricides on tick-infested sheep and goats was assessed. Two pyrethroid acaricides, 0.15% sumicidin and 0.20% butox were sprayed on individual animal one by one or on group of ten animals kept in small enclosures at a time, totally involving 40 sheep and 40 goats for each method. The efficacy, as seen from the total efficacy score (TES) of the former method of spraying, was found to be higher than the latter. But the advantages of the group spraying were that it saved the time in spraying and the quantity of acaricidal emulsion.

Haematology and serum chemistry was studied in young (5-6 months) and adult (2-2½ years) changthangi goats (Capra hircus) to investigate the age associated changes in blood constituents. Significant difference was recorded in most of the haematological and biochemical indices between two age groups. Higher values were recorded for total erythrocytes (16.63 ± 0.61 and 12.79 ± 0.56 x 106 / cumm) in young and adult respectively when compared to reference values for goats which speaks of its adaptation to high altitude hypoxic conditions. The total leukocyte count (9.99 ± 0.72 x 103/ cumm) in young was significantly (P0.01) higher as compared to the adults (6.38 ± 0.65 x 103/ cumm). Present study has shown significant (P0.01) age related difference in differential leukocyte count, with neutrophils high in young and lymphocytes in adults. Biochemical studies revealed age associated difference with total proteins (7.48 ± 0.08 g/ dl), cholesterol (108.40 ± 6.26 mg/ dl), triglycerides (99.20 ± 7.79 mg/dl), LDL (20. 20 ± 2.01mg/dl), HDL (68.14 ± 3.65mg/ dl) and creatinine (0.92 ± 0.04 mg/ dl) higher in adults and enzymes like ALP (151.31 ± 10.26 u/l) and AST (165.43 ± 4.7 u/l) higher in young. The study indicated that age be considered while interpreting the clinical and experimental data.

O objetivo desta pesquisa foi determinar a influência do uso da plasmaferese sobre o tempo de recuperação clínica e hematológica de caprinos doadores de sangue total ou plasma. Para tanto, foram utilizados 20 caprinos adultos e clinicamente sadios, distribuídos por dois grupos de dez animais cada, a saber: grupo controle (de animais doadores de sangue total não tratados) e grupo experimental (de animais doadores que foram tratados com a plasmaferese). Os caprinos foram selecionados e monitorados por meio de exames físicos (funções vitais) e complementares (hemograma, proteínas totais, albumina, globulinas, relação A:G, ureia, creatinina e hemoglobina livre no plasma) realizados nos seguintes momentos: imediatamente antes e após a doação de sangue: 12, 24, 72, 120, 240, 360, 480 e 720 horas após os procedimentos. Os resultados foram analisados com comparações dentro e entre os dois grupos nos diferentes momentos do estudo. As observações clínicas efetuadas durante o período de até 30 dias após a doação de 20% do volume sanguíneo total, com ou sem a realização da plasmaferese nos animais dos grupos estudados, não sofreram variações influenciadas por esses procedimentos. Observou-se significativa variação dos componentes do eritrograma, tendo o grupo experimental apresentado as melhores taxas de recuperação em função do tempo. Com base nos resultados obtidos, a aplicação da técnica da plasmaferese em caprinos mostrou-se eficiente como recurso para a otimização do tempo de recuperação dos valores do hemograma de animais doadores de plasma, não determinando hemólise durante o seu procedimento. | The objective of this study was to determine the influence of plasmapheresis on clinical and haematological recovery time of whole blood or plasma donor goats. For this, 20 clinically healthy adult goats were divided into two groups of ten animals each: control group (not-treated whole blood donor animals), and experimental group (donor animals which were treated with plasmapheresis). Goats were selected and evaluated through physical examination (vital functions) and complementary tests (complete blood counts, total proteins, albumin, globulin, albumin:globulin ratio, urea nitrogen, creatinine, and plasma free haemoglobin) were carried out at the following moments: immediately before and after blood donation, 12, 24, 72, 120, 240, 360, 480, and 720 hours after the procedures. Results were analysed comparing animals in and between both groups (at differents moments of the study). The clinical observations made during the period of 30 days after donation of 20% of total blood volume, with or without plasmapheresis in the animals of studied groups, were not influenced by these procedures. The results revealed significant variation of eritrogram components, showing the experimental group to have better recovery rates according to time. Based on the results obtained in the present study, plasmapheresis technique application in goats showed to be efficient as a resource to optimize recovery time of blood cell values of plasma donor animals, and did not cause hemolisis during its procedure.

Foi realizado um levantamento soroepidemiológico da leptospirose em caprinos da microrregião do Seridó Oriental, Estado do Rio Grande do Norte, com o objetivo de determinar a prevalência de anticorpos anti-Leptospira spp. e identificar fatores de risco associados à infecção. Foram colhidas amostras de soro sanguíneo de 366 cabras em idade reprodutiva de 12 rebanhos. Para o diagnóstico sorológico da infecção por Leptospira spp., foi utilizada a Soroaglutinação Microscópica (SAM) com uma coleção de 24 sorovares de leptospiras vivas como antígenos. Dos 366 caprinos investigados, 53 foram soropositivos para pelo menos um sorovar de Leptospira spp., resultando em uma soroprevalência 14,5% (IC 95% = 11,0 - 18,5). O sorovar mais frequente foi o Autumnalis (73,6% das reações positivas). Não foram encontradas variáveis associadas à ocorrência de leptospirose (p >; 0,05). | A sero-epidemiological survey was conducted to determine the prevalence of anti-Leptospira spp. antibodies as well as to identify risk factors associated with infection in goats of the Seridó Oriental microregion, Rio Grande do Norte State, Northeastern Brazil. Serum samples from 366 adult goats from 12 herds were collected. For serological diagnosis of Leptospira spp. infection, the microscopic agglutination test (MAT) was carried out using 24 live Leptospira spp. serovars as antigens. Out of the 366 investigated goats, 53 were seropositive for at least one Leptospira spp. serovar, resulting in a seroprevalence of 14.5% (95% CI = 11.0% - 18.5%). The most prevalent serovar was the Autumnalis (73.6% of the positive reactions). There were no variables associated with leptospirosis occurrence (p >; 0.05).
