Brucellosis due to Brucella suis in a swine herd associated with a human clinical case in the State of São Paulo, Brazil

Brucella suis has been recognized as the major etiological agent of human brucellosis in areas free from Brucella melitensis infection. However, with changes in swine management, the occurrence of swine brucellosis has decreased as has the human incidence of B. suis infection. A swine brucellosis outbreak within a herd from Jaboticabal (So Paulo, Brazil) was detected in July 2006. The herd comprised approximately 300 sows and 1,500 finishing animals. Many sows within this herd experienced abortions, while others exhibited vaginal discharge; three sows suffered posterior paralysis. Among 271 sows, 254 (93.7%) tested positive for brucellosis by complement fixation, and among 62 randomly bled finishing animals, 17 (27.4%) also tested positive. The B. suis biovar 1 was cultured from 14 aborted fetuses and six sows. Brucella was identified using routine methods. Fourteen farm workers were tested using agglutination tests, with three workers showing evidence of Brucella antibody titers. A 39-year-old woman, who worked with maternal pigs and had direct contact with aborted fetuses, presented an agglutinating titer of 480 IU/mL and displayed clinical signs of infection. Our findings suggest that despite a reduction of swine brucellosis throughout Brazil, B. suis infection still occurs, thereby posing a zoonotic risk.

Prevalência de Streptococcus suis sorotipo 2: discussão da literatura brasileira

Streptococcus suis is considered worldwide as one of the pathogens of biggest health and economic impact in the swine industry. Among the serotypes described as zoonotic, serotype 2 is the most frequently isolated from diseased animals and humans in most countries. The study of the epidemiology of S. suis infections in Brazil is important and may help in the development of effective control measures. The aim of this study was to conduct a critical review of Brazilian literature, with support of the world literature, addressing the diagnosis of the agent and its prevalence in clinically ill animals and healthy carriers, especially regarding to the prevalence of the serotype 2 in the country.

Infecções por helmintos em Javalis (Sus scrofa scrofa) criados em cativeiro na região Noroeste do Estado de São Paulo, Brasil

O estudo foi desenvolvido no período de outubro de 2001 a maio de 2002, com 51 javalis (Sus scrofa scrofa) proveniente de duas propriedades situadas nos municípios de Mirassol e Fernandópolis, Estado de São Paulo, sendo 18 animais variando de 150 a 360 dias (Grupo I) e 33 animais entre 30 a 120 dias de vida (Grupo II). O objetivo da investigação foi identificar a helmintofauna e obter subsídio para melhor conhecimento da instalação das infecções helmínticas. Foram identificadas nos dois grupos, respectivamente, oito espécies de nematódeos com as seguintes prevalências: Trichuris suis (16,7% e 30,3%); Metastrongylus salmi (50,0% e 15,2%), Metastrongylus pudendotectus (5,6% e 3,0%); Strongyloides ransomi (27,8% e 12,1%); Ascaris suum (0,0% e 3,0%), Ascarops strongylina (27,8% e 0,0%); Physocephalus sexalatus (5,6% e 0,0%); Oesophagostomum dentatum (22,2% e 0,0%). O total de nematódeos colhidos e identificados nos dois grupos de animais foi de 7958, assim distribuídos: 6573 no intestino grosso (82,6%), 1246 no pulmão (15,7%), 89 no intestino delgado (1,1%), e 50 no estômago (0,6%). As maiores variações de intensidade foram obtidas por T. suis de 1 a 1764 e por M. salmi 1 a 248 exemplares.

Anthelmintic efficacy of ivermectin and abamectin, administered orally for seven consecutive days (100 mu g/kg/day), against nematodes in naturally infected pigs

The present study aimed to evaluate ivermectin and abamectin, both administered orally in naturally infected domestic swine, as well as analysing if the EPG (eggs per gram of faeces) values were equivalent with the ivermectin and abamectin efficacy obtained by 'parasitological necropsies. The animals were randomly selected based on the average of three consecutive EPG counts of Strongylida, Ascaris suum and Trichuris for experiment I, and of Strongylida and Trichuris for experiment II. After the random draw, eight animals were treated, orally, during seven consecutive days with 100 mu g/kg/day ivermectin (Ivermectina (R) premix, Ouro Fino Agronegocios), eight other animals were treated, orally, during seven consecutive days with 100 mu g/kg/clay abamectin (Virbamax (R) premix - Virbac do Brasil Industria e Comercio Ltda.), and eight pigs were kept as controls. EPG counts were performed for each individual animal at 14th day post-treatment (DPT). All animals (control and treatment) were necropsied at the 14th DPT. The results from both experiments demonstrate that both ivermectin and abamectin, administered orally for a continuous period of seven days, at a daily dosage of 100 mu g/kg, were highly effective (>95%) against Hyostrongylus rubidus, Strongyloides ransomi, Ascaris suum and Metastrongylus salmi. Against Oesophagostomum dentatum, abamectin presented over 95% efficacy against both evaluated strains, while ivermectin reached other strain as resistant. Regarding T. suis, both ivermectin and abamectin were effective (efficacies >90%) against one of the tested strains, while the other one was classified as resistant. Furthermore, the EPG values were equivalent with the ivermectin and abamectin efficacy obtained by parasitological necropsies. (C) 2014 Elsevier Ltd. All rights reserved.

Retorno à atividade reprodutiva de touro angus após fimose traumática com obliteração parcial da luz prepucial: relato de caso

The main disturbs affecting the genital segment of bulls are balanitis, phimosis and preputial injuries, abscesses or prolapses, resulting in decreased libido or mating ability. One case of traumatic phimosis with partial obliteration of preputial lumen is reported in Aberdeen Angus bull. During anamnesis, it was reported that the animal was unable to expose the penis and presented increased penile and preputial volume of unknown etiology after being submitted to a libido test. During clinical examination, a firm preputial mass of 15 cm in diameter was observed in the middle third of the prepuce and stenosis of preputial lumen was detected approximately 17 cm from the preputial orifice. Reconstructive surgery was the chosen therapy, with amputation of the affected foreskin portion. A skin segment of about 12 cm and affected mucosal portion were removed. Postoperative therapy consisted of dressing with chlorhexidine digluconate based ointment, povidone iodine and topical insect repellent (cypermethrin and carbamyl), systemic antibiotic therapy with benzathine penicillin (30,000 IU / kg, repeated after 48 hours) and anti-inflammatory therapy with flunixin meglumine (2 , 0 mg / kg SID) for three days. After twenty days, semen was collected by massage of the accessory glands. The ejaculate volume was 3 mL, with 200x106 spermatozoa / mL, white color, "suis generis" odor, 88% of motile sperm, 64% of progressively motile sperm and 82% of rapid sperm. Thus, the chosen surgical treatment was effective to correct the pathology and reintroduce the animal into reproductive activity
