Toxoplasma gondii genotyping in a dog co-infected with distemper virus and ehrlichiosis rickettsia

Abstract: This paper reports a toxoplasmosis, erhlichiosis and distemper co-infection in a dog with an exuberant neuropathological clinical picture. Primary involvement was discussed based on information collected in the analysis of the clinical case, such as neurological impairment, epidemiological data, poor immunoprophylactic scheme of the dog affected and the role of these diseases on immunosuppression. Canine distemper and ehrlichiosis were diagnosed based on epidemiologic data, clinical signs, hematological and cytological evaluation. Toxoplasma gondii was isolated and genetically characterized as Type I using restriction analysis (RFLP) with SAG-2 genes. Immunosuppression features of both dogs and human beings are discussed, as well as implications on animal and public health. This is the first report on toxoplasmosis, ehrlichiosis and distemper co-infection in a dog in Brazil, associated with genotyping determination of the T. gondii strain involved.

Feeding bottle teats

Abstract: The disclosure relates to a teat, particularly for feeding bottles for babies, which teat has a nipple portion made particularly with a conically orthopaedic shape upon a base portion with an opening away from the nipple portion, which base portion can be fitted upon a bottle neck so as to grip around the latter with a cylindrical wall portion and also has inwardly directed projections.

Occurrence of antibodies to Toxoplasma gondii in mules and donkeys in the northeast of Brazil.

Abstract: The aim of the present study was to investigate antibodies to Toxoplasma gondii in the serum of mules and donkeys bred in the northeast of Brazil In total, 483 samples were used (395 mules and 88 donkeys) from 4 states (Pernambuco, Rio Grande do Norte, Paraiba, and Sergipe) The indirect immunofluorescence reaction (IFI) technique was used to investigate antibodies to T gondii with a cut-off point of 64 Positive frequencies of 238% and 432% were recorded for mules and donkeys, respectively The state of Pernambuco had the highest prevalence of positive samples (29%) with statistically significant differences for species (P < 0001) and state (P = 0048) This is the first study of antibodies to T gondii in mules and donkeys in these 4 states of the northeastern region of Brazil and serves as a warning to health authorities regarding the risks of ingesting equine meat

β-Lactam Resistance Genes: Characterization, Epidemiology, and First Detection of blaCTX-M-1 and blaCTX-M-14 in Salmonella spp. Isolated from Poultry in Brazil—Brazil Ministry of Agriculture's Pathogen Reduction Program

Abstract: Salmonella spp. are widespread in nature; however, human infections occur mainly through ingestion of contaminated food, specially poultry and eggs. In Brazil, the Ministry of Agriculture (MAPA) oversees food production in general, with the goal of preventing transmission of pathogens through the food chain. In 2004, MAPA initiated a program to monitor and control levels of Salmonella in poultry during slaughter. This study analyzes isolates from MAPA's program for β-lactam resistance and the resistance genes involved, as well as the geographic distributions of potentially clonal populations of resistant isolates within Brazil. Initially, 1,939 Salmonella spp. isolated between 2004 and 2011 were examined. These isolates were tested for antimicrobial susceptibility, and 100 isolates resistant or intermediate to ampicillin and ceftriaxone were screened initially for the presence of blaSHV, blaTEM, blaOXA, blaPSA, blaCMY-1, and blaCMY-2 genes. There were 55 isolates whose resistance genes were not identified by this panel and these isolates are the subject of this report. These 55 isolates were differentiated into 31 distinct ribogroups, with multiple β-lactam resistance genes, including AmpC blaCMY, blaTEM, blaCTX-M-1, blaCTX-M-2, blaCTX-M-8, and blaCTX-M-14. Isolates carrying variants of blaCTX-M were identified in three geographic regions. Salmonella carrying particular genetic variants of blaCTX-M and belonging to the same ribogroup were identified from multiple poultry slaughtering facilities. In some instances, these presumptive clonal-related isolates were from facilities over 300 miles apart, indicating potential clonal spread between two geographic regions. This is the first report of blaCTX-M-1 and blaCTX-M-14 in Salmonella in Brazil.

Mineral characterization of native fruits from the southern region of Brazil

Abstract: Although the greatest variety of Brazilian flora is in the Amazon region, the Southern region of Brazil also has an estimated number of at least 5,000 species of vascular native plants. These species have been neglected as potential food sources, remaining unknown and under-utilized and limiting the potential variety in the diet of Brazilians and other peoples. Therefore the aim of this study was to characterize the mineral composition and content present in seven native fruit species of Southern Brazil using inductively coupled plasma optical emission spectrometry (ICP-OES). The essential element concentrations in the fruit samples were higher or similar to the values reported for traditional fruits. The araticum-do-mato fruit samples had high concentrations of the elements Ca, K, and Cu, and trace elements such as Pb and Sr. Mandacaru-de-tres-quinas had predominance of Ba, Bi, and Ga, and the essential elements Mg and Mn. Uvaia and guabiroba had the highest levels of Al and Cr, but uvaia had high levels of Fe and Zn. The pindo palm had high amounts of Cd and Ni, and the yellow guava had high concentrations of Na, while red guava had high levels of Co.
