ETIOLOGICAL AND PATHOLOGICAL STUDY OF EPIDEDE/lY'I‘IS IN GOATS IN BAGHDAD CITY

Testes from 700 male goats aged l - 3 years , slaughtered at Baghdad abatteir, were examined during 6 months period. Histological and bacteriological examinations were done when gross lesions were observed. The results revealed that epidedimytis was observed in 21 (3%) of the examined animals ; 16 (2.3%) cases were unilaterally affected and S (0.7%) cases were bilaterally affected. Bacteriological isolations from infected organs included : Corynebacterium ovis (6 isolates) and Actinomyces pyogenes (3 isolates) both constituted the majonty of isolates ; as well as E. coli (4 iso-lates), and Pseudomonas aeruginosa , Staphylococcus epidermidis, Cory. bovis., Staph. aureus, Cory , ulcerams &. Yersinia pseuclotuberculosis ( 2 isolates of each ) and Campylobacter fetus (1 isolate). Histopathological examination showed 6 pathological patterns of epididmytis including acute epididymitis (14.2% of infected cases ) , subacute nomsuppurative epididymilis (9.5% od cases ) , chronic suppurative epididymitisd (28.5% of cases ), chronic non—suppurative epididymitis (19% of cases) and spermatic granuloma (14.2% of cases ).

Situação da tuberculose em ovinos consorciados com bovinos leiteiros na região sudoeste maranhense

RESUMO: Objetivando conhecer a situação da tuberculose ovina no Maranhão, avaliaram-se 343 ovinos da região sudoeste do estado, 247 fêmeas e 96 machos, com idade acima de 6 meses, por meio do teste cervical comparativo (TCC), com inoculação de tuberculinas na região cervical direita. Cranialmente, injetou-se derivado proteico purificado (PPD) aviário; e caudalmente, PPD bovino, em doses individuais de 0,1 mL. Todos os animais apresentaram resultado negativo para tuberculose, entretanto, 65 ovinos apresentaram reação à tuberculina bovina superior à aviária. Para investigar a possibilidade de baixa sensibilização ou anergia em animais com tuberculose avançada, foi necropsiado um ovino caquético, idade acima de quatro anos, com resultado negativo ao TCC, porém, com reação à tuberculina aviária e linfonodos aumentados com consistência endurecida. Os resultados indicaram infecções por C. pseudotuberculosis, Actinomyces pyogenes, Staphylococcus aureus e Mycobacterium sp. A cultura e o isolamento resultaram em Pseudomonas aeruginosas e Bacillus sp. Não foram visualizadas estruturas bacterianas compatíveis com bacilo álcool ácido resistente (BAAR). Os resultados confirmam ausência de animais reagentes ao M. bovis, pressupondo inexistência da tuberculose em ovinos na região estudada.

An outbreak of dermatophilosis and caseous lymphadenitis mixed infection in camels (Camelus dromedaries) in Jordan

Introduction: This study describes and reports, for the first time, an outbreak of dermatophilosis that occurred concurrently with caseous lymphadenitis involving two camel herds (Camelus dromedaries) in north Jordan. Methodology: The affected animals were part of two herds comprising 52 Arabian camels in herd 1 and 65 camels in herd 2. The age of infected camels ranged from 18 months to 5 years. Pus and skin scab samples were aseptically collected and bacteriologically examined. Affected camels were treated by long-acting oxytetracycline injection in a dose rate of 10 mg/kg body weight every 48 hours for three successive treatments, and local antiseptic and antibiotic cutaneous spray treatment for five successive days. Results: The main clinical signs on affected camels were skin dermatitis and abscess formation. The isolated organisms were Dermatophilus congolensis and Corynebacterium pseudotuberculosis were the causative agents of dermatophilosis and caseous lymphadenitis, respectively. Other organisms were isolated from skin abscesses, including α-hemolytic streptococci, hemolytic E. coli, Actinomyces pyogenes, and S. aureus. The affected camels were rapidly and effectively cured by the above-mentioned treatment protocol. No mortality was recorded. Conclusions: Introducing purchased camels from animal auctions without pre-examination and keeping camels in over-crowded small barns under cold, humid, and rainy conditions during winter may predispose the eruption of mixed infection of dermatophilosis and caseous lymphadenitis. Treatment by long-acting oxytetracycline injection with local antiseptic and antibiotic cutaneous spray can control such infection. A survey on camel herds raised near Jordan’s borders is needed to monitor the possibility of emerging infectious disease.

Evaluación citológica y microbiológica de lavados uterinos en bovinos con problemas reproductivos (estudio preliminar)

RESUMENObjetivo. Determinar las características citológicas y microbiológicas de lavados uterinosde bajo volúmen en hembras con problemas reproductivos en dos hatos del AltiplanoCundiboyacense. Materiales y métodos. Se evaluaron 21 muestras de lavados uterinosde vacas con historia de problemas reproductivos procedentes de dos hatos lecheros, enel primer hato ubicado en Sibaté (Cundinamarca) se muestrearon 10 animales y en elsegundo ubicado en Ventaquemada (Boyacá) se obtuvieron las 11 muestras restantes. Serealizó evaluación macroscópica y microscópica de cada uno de los lavados uterinos; parala evaluación citológica se utilizaron las tinciones de Gram y Wright. La determinación de laflora bacteriana se realizó mediante técnicas estándar en microbiología para la identificaciónde bacterias no exigentes, adicionalmente se realizaron pruebas de sensibilidad por latécnica de difusión de Kirby-bauer. Resultados. En la citología se observaron bacilosy cocos gram positivos, células epiteliales de descamación uterina (CEDU) y respuestainflamatoria (RI) mediada por polimorfonucleares (PMN). Los aislamientos bacterianoscorrespondieron a Lactobacillus sp como flora bacteriana normal del tracto genital (16.66%)y Klebsiella sp como flora acompañante (16.66%); adicionalmente se aislaron bacteriaspatógenas causantes de problemas reproductivos como Streptococcus sp. β hemolítico(33.33%), Streptococcus sp α hemolítico (50%) y Streptococcus sp. γ hemolítico (50%)y Arcanobacterium pyogenes (Corynebacterium-Actinomyces pyogenes) (16.66%); en un9.52% de las muestras se observaron espiroquetas. Conclusiones. Se observó una relacióndirecta entre el aspecto macroscópico de los lavados uterinos, la respuesta citológica y elaislamiento de bacterias.

Contribution à l’étude de la maladie des abcès chez le dromadaire (Camelus dromedarius) dans la région de Nefzaoua (sud-ouest de la Tunisie)

Les résultats d’une enquête épidémiologique et clinique, et d’examen bactériologique relative à la maladie des abcès chez le dromadaire dans la région de Nefzaoua (sud-ouest de la Tunisie) sont présentés. L’étude épidémiologique a concerné 33 élevages en extensif ainsi que des dromadaires exploités dans le secteur touristique. Les études clinique et bactériologique ont porté sur 38 animaux issus de ces élevages. Cliniquement, la maladie n’a pas affecté l’état général de l’animal et a souvent touché les noeuds lymphatiques cervicaux inférieurs et préscapulaires en un nombre d’un ou deux abcès par animal atteint. La forme interne de la maladie n’a pas été observée sur les soixante-douze carcasses abattues dans l’abattoir de la région. La morbidité de la maladie dans la région a été de 9 p. 100. Cette maladie a souvent touché les jeunes dont l’âge était inférieur à un an. Les facteurs favorisants les plus incriminés dans l’apparition de la maladie ont été : le tatouage, le regroupement des animaux provenant de différents élevages et l’infestation par les tiques. Différents germes ont été isolés, notamment les staphylocoques (53 p. 100 des cas), Corynebacterium pseudotuberculosis (18 p. 100) et Actinomyces pyogenes (26 p. 100).
