Ocorrência e distribuição de esporos de Clostridium botulinum tipos C e D em áreas de criação de búfalos na Baixada Maranhense

Botulismo é enzoótico na criação de búfalos da Baixada Maranhense, Estado do Maranhão. No presente trabalho foram realizados estudos para verificar a ocorrência e distribuição de esporos de Clostridium botulinum tipos C e D em amostras de solo, limo e fezes de búfalos, colhidas aleatoriamente em áreas inundáveis da criação de búfalos nessa Baixada. A evidenciação de esporos foi realizada em 40 amostras de fezes, 65 de limo e 35 de solo, provenientes de quatro munic��pios, pelo cultivo em meio de cultura com carne cozida e posterior inoculação do sobrenadante filtrado em camundongo, na tentativa de verificação da presença de toxina botulínica. A tipificação de amostras positivas foi realizada pela microfixação de complemento. Os resultados revelaram que 104 (74,28%) das 140 amostras examinadas foram positivas para a presença de esporos de C. botulinum pelo teste indireto. Não houve diferença significativa (P>0,05) entre os valores obtidos quando das análises das amostras de solo (77,1%), limo (60,0%) e fezes (95,0%). Das 28 amostras de solo, limo e fezes positivas, que foram utilizadas para a tipificação, quatro (14,29%) foram classificadas como tipo C, 23 (82,14%) como tipo D e uma (3,5%) como pertencente ao complexo CD. Os resultados revelaram uma alta contaminação ambiental por C. botulinum em áreas de criação de búfalos da Baixada Maranhen-se. A identificação de outros tipos e de subtipos de C. botulinum não foi realizada.

Esporos e toxinas de Clostridium botulinum dos tipos C e D em cacimbas no Vale do Araguaia, Goiás

Foram avaliadas a ocorrência e distribuição de esporos e toxinas de Clostridium botulinum tipos C e D em 300 cacimbas empregadas como bebedouro de bovinos em 130 propriedades rurais localizadas em 12 munic��pios do Vale do Araguaia, Estado de Goiás. A presença de esporos foi determinada indiretamente pelo cultivo em meio de cultura, seguido da inoculação e neutralização em camundongo das amostras de sedimento do interior das cacimbas, e do solo superficial e fezes de bovinos, coletadas ao seu redor. A presença de toxina foi avaliada diretamente pela inoculação em camundongo do sedimento filtrado das cacimbas, também seguida da neutralização em camundongo com antitoxinas C e D. A presença de esporos de C. botulinum foi significativamente maior (p<0,05) nas fezes de bovinos (31%), quando comparadas com os resultados das amostras de solo superficial (19%) e dos sedimentos (10%). Foram detectadas toxinas botulínicas dos tipos C, D, ou classificadas como pertencentes ao complexo CD, em seis amostras (2%) das 300 cacimbas. Das 130 propriedades trabalhadas, em 122(93,85%) foram encontrados esporos ou toxinas de Clostridium botulinum em pelo menos uma das variáveis pesquisadas, enquanto somente 8(6,15%) não apresentaram qualquer contaminação A idade e profundidade das cacimbas estiveram associadas com a freqüência de detec��ão de esporos e toxinas. Assim, quanto mais velhas e rasas, maior a freqüência do isolamento de esporos e toxinas. A contaminação das cacimbas do Vale do Araguaia goiano com esporos e toxinas do Clostridium botulinum tipos C e D demonstra o risco potencial permanente e crescente para a ocorrência da intoxicação botulínica de origem hídrica nos bovinos.

Botulism by Clostridium botulinum type C in goats associated with osteophagia

An outbreak of botulism was detected in goats in the semiarid region of Brazil. In a flock of 460 goats, 38 does were affected and 37 died. Kids and younger goats were not affected. The main clinical signs were flaccid tetraparesis leading to tetraplegia that was often accompanied by twisted neck, tongue paralysis, and muscle tremors. At the time of the visit, 4 out of 11 affected goats were recumbent. Ambulatory goats had uncoordinated and swaying gaits with hypometria and weakness, mainly of the hind limbs. Two recumbent and four ambulatory goats showed twisted neck. Two recumbent goats were euthanized and necropsied. Non-significant gross and histologic lesions were observed. Samples of the liver, gut and rumen content were collected from the two goats and examined for botulinum toxins using the mouse serum neutralization test. The three samples from one goat were positive for type C toxin. Marked osteophagia was observed when the goats had access to bones in the pasture, and the farmer mentioned that osteophagia was common among goats of the flock. A sample of the plant Hybantus ipecaconha, the most abundant forage available for the goats, contained 2800 mg/kg of Ca and 450 mg/kg of P. One soil sample contained 58.12 mg/kg of Ca and 2.02 mg/kg of P. It was concluded that in this outbreak, botulism was associated with osteophagia probably due to phosphorus deficiency.

Intoxicação natural por Clostridium botulinum tipo C: em grupo de aves domésticas

Clostridium botulinum causative of toxic infections due to toxin ingestion previously formed, occur in several ingestion species, mainly birds. In a poultry farm, located at São Paulo State, more than 3,000 birds have been attacked by this toxic infections, when the birds showed motionless, loss of weight, accelerated, breathing, resulting in death of the birds. The blood harvest for attainment of the serum and later necropsy was carried out throwgh the following samples: liver, gizzard, crop, feed, water and litter. After that, the toxin was extracted by gelatin-phosphate buffer and inoculation in mice, isolation of the agent in Blood. Ágar and Reinforced Clostridium Ágar and neutralization of toxin determine its type. The inoculation in mice showed positive results in samples of liver, gizzad, crop and symptoms like was waist, and death of the birds by limp paralysis. The colonies that have been isolated, suspected of Clostridium botulinum showed expected results and further analysis revealed positive results to botulinical toxin type C. The farms have to pay attention in the routine jobs, choicer, and elimination of carcass because they are essential to keep this problem away.

Ocorrência de Clostridium botulinum tipos C e D em criatórios de bovinos no munic��pio de Cocalinho, Vale do Araguaia, Mato Grosso

In order to assess the occurrence and distribution of spores and toxins of Clostridium botulinum types C and D in three farms in Cocalinho, at the Araguaia River valley, State of Mato Grosso, Brazil, we analyzed sediment samples from 40 water holes, soil and cattle feces, collected around water holes. Sediments were analyzed by direct method, whilst feces, soil and also sediment samples were individually analyzed by indirect method. The detection of spores and botulinum toxins in the filtered material was performed by bioassay in Swiss Webster mice strain, as well as the serum-neutralization of the positive materials for typing. Samples of cattle feces showed the largest positive rate for C. botulinum, with 25/40 (62.5%), followed by soil, 12/40 (30%), and by sediment, 13/40 (32.5%). From the 40 cattle feces samples, 25 (62.00%) were positive for Clostridium botulinum; six samples were identified as type C, other six as type D, and 13 samples were classified as CD complex. From the equal number (40) of soil samples, 12 (30%) were positive for C. botulinum; two samples were identified as type C, other three as type D, and seven samples were classified as CD complex. Regarding the 40 sediment samples, 13 (32.5%) were positive for C. botulinum; two samples were identified as type C, other three as type D, and eight samples were classified as CD complex. No botulism toxin was detected by indirect method.

[Occurrence of Clostridium perfringens type A and type C in piglets of the Swiss swine population]

Necrotizing enteritis (NE) of newborn piglets still represents an economical problem in Swiss pig breeding and production. The aim of our study was to identify risk factors for NE and evaluate the prevalence of C. perfringens with the toxingenes cpb and cpb2 in Swiss pig breeding farms. The prevalence of theses C. perfringens was investigated using fecal swabs followed by bacteriological culturing and genotyping. Close proximity to other breeding farms and large herd sizes were shown to predispose to NE. C. perfringens type C, carrying the genes cpa, cpb and cpb2 were frequently identified in herds with acute outbreaks of NE. Farms not affected by NE or those using prophylactic vaccination against NE were predominantly positive for C. perfringens type A strains with cpb2 and showed much lower prevalence of C. perfringens type C, compared to acutely affected herds. Our results demonstrate that C. perfringens type A strains with cpb2 are not associated with NE. Besides typical necropsy finding, only the identification of cpb can be used for the diagnosis of NE in affected herds.

Detection of Clostridium perfringens type C in pig herds following disease outbreak and subsequent vaccination

Immunisation of sows using Clostridium perfringens type C toxoid vaccines is recommended to prevent necrotising enteritis (NE) on pig breeding farms. Absence of disease, however, oftentimes leads to the false assumption of pathogens being eradicated. The prevalence of C perfringens type C was determined by PCR in faecal samples of piglets and sows in three Swiss pig breeding farms two to four years after implementation of a vaccination programme following disease outbreaks. C perfringens type C could still be detected several years after an outbreak despite absence of NE. In-herd prevalence of the pathogens varied significantly between the farms and was also lower compared with a farm which experienced a recent outbreak. In conclusion, C perfringens type C can be detected on once-affected farms, even in the absence of NE for several years.
