We describe an outbreak of mandibular abscess in Bergamácia sheep from the municipality of Botucatu, São Paulo, Brazil. In a herd of 120 sheep, 35 showed an increase of the mandibular volume with presence of a single nodule of stony consistency and different sizes, often fistulated but with no signs of inflammation in the surrounding soft tissues. The sheep were raised on a Panicum maximum cv. Tanzania pasture, with water and mineral salt ad libitum, and were treated orally against parasites with drenching pistols. Material for microbiological diagnosis and antibiogram was collected from the nodules of five affected sheep, through puncture and aspiration. From 35 affected sheep, 19 were submitted to radiographic examination, one was submitted to computer tomography and another to bone biopsy of the submandibular region. The only sheep that died was in a state of cachexia, probably due to the location of the volume increase which affected the molar hindering apprehension and appropriate chewing. Necropsy revealed areas of caseous necrosis in the jaw, from where Pseudomonas aeruginosa was isolated. The sheep were treated with intramuscular application of 10% sodium iodide and the antobiotgic enrofloxacin, but with little efficacy. Based on the clinical data from medical records, the location of lesions in the jaw bone, the result of microbiological culture, radiographic and computer tomography, the diagnosis of mandibular abscesses due to Pseudomonas aeruginosa infection was made.

Descreve-se um surto de abscesso mandibular em ovelhas da raça Bergamácia no município de Botucatu, estado de São Paulo. Do rebanho de 120 animais, 35 apresentaram aumento de volume mandibular com a presença de nódulos únicos, de consistência pétrea, de diferentes tamanhos, fistulados ou não e sem indicativos de inflamação dos tecidos moles adjacentes. Os animais eram criados em pasto de Panicum maximum cv. Tanzânia com água e sal mineral ad libitum e everminados, via oral, com pistolas dosificadoras. O material para diagnóstico microbiológico e antibiograma foi coletado de cinco animais acometidos, por punção e aspiração dos nódulos. Dos 35 animais acometidos, 19 foram submetidos ao exame radiográfico, um ao exame tomográfico e outro à biópsia óssea da região submandibular. O único ovino que morreu, encontrava-se em estado de caquexia provavelmente devido à localização do aumento de volume que afetou a implantação dos dentes molares daquela região impedindo a apreensão e mastigação adequadas levando a perda da condição corporal e morte. Ao exame necroscópico, observaram-se áreas de necrose caseosa na mandíbula direita de onde isolou-se Pseudomonas aeruginosa. O tratamento utilizado foi baseado na aplicação de iodeto de sódio a 10% por via intramuscular e antibioticoterapia segundo antibiograma com enrofloxacina por via intramuscular, porém com pouca eficácia. Diante do quadro clínico, dos dados de anamnese, da localização das lesões no tecido ósseo mandibular, do resultado do cultivo microbiológico, das alterações radiográficas e tomográficas foi feito o diagnóstico de abscesso mandibular causado por Pseudomonas aeruginosa.

The serotype characterization, antimicrobial susceptibility profile, and clinical-epidemiological findings were evaluated in 53 Salmonella spp. strains isolated from 41 dogs, nine horses and three cattle presenting different clinical manifestations between 1997 at 2007. Salmonella Typhimurium (45.3%), Salmonella enterica (22.6%), Salmonella Enteritidis (7.5%), Salmonella enterica subsp. enterica 4,5,12i (5.7%), Salmonella Newport (5.7%), Salmonella Dublin (3.8%), Salmonella Agona (3.8%), Salmonella Glostrup (3.8%), Salmonella Saintpaul (1.8%) were the more common serotypes. Ciprofloxacin (100.0%), norfloxacin (100.0%) and gentamicin (100.0%) were more effective drugs while resistance of isolates was observed to ceftiofur (28.5%) and florfenicol (7.0%). The strains were isolated from animals with enteritis, urinary tract infections, septicaemia, pyometra, pneumonia and conjuntivits. The results showed the high frequency of Salmonella Typhimurium serotype in different animals studied. The study highlighted also the presence of serotypes in our animals that also have been identified in humans with salmonellosis.

Foram caracterizados os sorotipos, o perfil de sensibilidade microbiana e os achados clínico-epidemiológicos em 53 linhagens do gênero Salmonella isoladas de 41 cães, nove equinos e três bovinos, acometidos por diferentes manifestações clínicas entre 1997 e 2007. Salmonella Typhimurium (45,3%), Salmonella enterica (22,6%), Salmonella Enteritidis (7,5%), Salmonella enterica subsp enterica 4,5,12i (5,7%), Salmonella Newport (5,7%), Salmonella Dublin (3,8%), Salmonella Agona (3,8%), Salmonella Glostrup (3,8%), Salmonella Saintpaul (1,8%) foram os sorotipos encontrados. Ciprofloxacina (100,0%), norfloxacina (100,0%) e gentamicina (100,0%) foram os antimicrobianos mais efetivos, enquanto a maior resistência das linhagens foi observada para ceftiofur (28,5%) e florfenicol (7,0%). As linhagens foram isoladas de animais com enterite, infecção do trato urinário, septicemia, piometra, pneumonia e conjuntivite. Ressalta-se para o predomínio do sorovar Typhimurium nas diferentes manifestações da salmonelose nos animais. Destaca-se, também, a identificação de sorotipos nos animais que também são observados em casos de salmonelose em humanos.

In last years increase the importance of milk quality and conditions of bovine milking. Simultaneously, increase the interest about organic milk and derivates. The aim of present study was investigate the milk pathogens, sensitivity and multiple drug resistance of isolates, somatic cell count and residues of drugs in milk, from cattle with and without mastitis, come from four little organic dairy farms in State of São Paulo, Brazil. Were used 148 cattle on the middle period of lactation. From these, two showed clinical mastitis, 72 subclinical mastitis and 74 without signs of mammary inflammation (control). Staphylococcus aureus (25.7%), Streptococcus spp. (21.4%), Corynebacterium bovis (12.9%), Streptococcus agalactiae (4.3%) and Staphylococcus spp (4,3%) were the more-frequent microorganisms isolated from animals with mastitis. Aspergillus spp. was isolated from one animal. Ceftiofur (95.2%), oxacillin (84.2%), gentamicin (76.3%) and cefoperazone (70.3%) were the more effective drugs. High resistance of isolates were found to penicillin (53.5%), ampicillin (41.6%) and neomycin (38.6%). Multiple drug resistance to three or more drug was observed in 40 (39.6%) isolates. Media of somatic cell count encountered in animals with mastitis and controls were 175,742.67cs/mL and 58,227.6 cs/mL, respectively. Antimicrobials residues in milk were detected in four (2.7%) animals. The present findings showed the low somatic cell count of animals, indicative of good quality of milk. However, pointed the need of control measures for contagious pathogens of bovine mastitis and more attention for prohibition of antimicrobial use in organic dairy farms.
