Highlights CPPV-1 was found in all females of the study, tested with qPCR. Was found CPPV-1 in fetal/maternal tissue in the post-mortem examination. Feline females (with and without Reproductive Failures) were negative for commonly-occurring RF viruses in the same (FIV, FeLV e FHV-1). Females showed clinical signs only related to RF and abnormalities WBCC. These results provide the first description of an FPV agent causing only RF-related clinical signs in queens.

In order to investigate the prevalence of viral diseases in vaquejada horses, samples were collected from Quarter Horse and Paint Horse breeds (males and females, aged between 2 and 15 years) from rural and urban areas of Mossoró, Rio Grande do Norte, Brazil were collected. The number of samples collected and tested varied with the techniques used: 132 serum samples were tested for vesicular stomatitis (VS) and equine viral arteritis (EVA), 118 for western and eastern equine encephalomyelitis (WEE/EEE), 114 for equine herpesvirus 1 (EHV-1), and 61 for equine influenza (EI). The techniques used varied according to the disease studied: tests for VS (Ribeirão and Alagoas strains), EVA, EHV-1, and WEE/EEE were performed using the seroneutralization technique in Vero cell cultures, while the test for for EI type-2 (H3N8) was performed using the hemagglutination inhibition technique. The following results were obtained: 39 (29.55%) and 6 (4.54%) VS-positive horses (n=132) harbored the Alagoas and Ribeirão strains, respectively; no animal tested positive for EVA (n=132); 11.01% (n=13) and 0.84% (n=1) animals tested positive for EEE and WEE (total n=118), respectively; and 22 out of 114 (19.29%) horses tested positive for EHV-1. The history of respiratory and reproductive diseases was statistically significantly (p = 0.02) related to the presence of antibodies against EHV-1. This is the first report of the seroprevalence of viral diseases in vaquejada horses in Rio Grande do Norte.

-The objective to evaluate antimicrobial activity of propolis and wax different species of stingless bees front of the pathogenic bacteria. Bees wax were collected Canudo (Scaptotrigona sp.), Jandaíra (Melipona subnitida) and Jati (Plebéia sp.), and two samples of propolis species Cupira (Partamona sp.) and Jati (Plebléia sp). For the analysis of the antimicrobial activity of wax and propolis in hydroalcoholic extracts were produced concentrations of 100, 75 and 50 µg/mL -1 and used diffusion technique discs. To evaluate the antimicrobial activity of the extracts were used strains Enterobacter aerogenes (ATCC 1304), Escherichia coli (ATCC 25922) and Staphylococcus aureus (ATCC 6538). It was observed that the extracts of Canudo bees wax, and Jandaíra Jati showed activity against the tested microorganisms. As for the propolis extracts was verified that the Cupira at concentration of 100 µg/mL -1 had activity against all the tested bacterial strains, as in other concentrations, only Staphylococcus aureus was inhibited their growth. The Jati propolis extract inhibited the bacteria Enterobacter aerogenes and Staphylococcus aureus at a concentration of 100 µg/mL -1 and E. coli suffered no inhibition. So the wax and propolis extracts of bee species assessed sting have antimicrobial potential against strains of microorganisms tested.

Mannheimia haemolytica (MH) é uma das principais causas da doença do complexo respiratório dos bovinos (DCRB) que causa grandes perdas econômicas. Até os dias atuais, não há relato de aves acometidas por tal bactéria. Relata-se um surto atípico de mannheimiose em emas em cativeiro (Rhea americana).

Article historyThis study aimed to evaluate the influence of sanitary inspection on the physicochemical characteristics, colour and texture of coalho cheese commercialised in the semiarid region of Brazil. One hundred and thirty-eight coalho cheese samples from commercial establishments in 46 Brazilian cities were evaluated, and physicochemical analyses (acidity, moisture, fat content, pH and ashes), as well as colour and texture tests were performed. The averages for the parameters in cheeses without the official sanitary inspection seal were 4,31, 0.34%, 50.34%, 55.9 and 4.83, for ash, relative acidity, moisture, fat content and pH and in samples with the official sanitary inspection seals we found values of 4,41, 0.32%, 51.51%, 55.37 and 4.92, for the same parameters, respectively. There was no difference in the colour and texture parameters, which for the samples with the official seal were 71.15, 1.43, 13.52 and 1.65; and for the ones without the official seal were 69.58, 1.50, 13.15 and 1.71 for L*, a*, b* and texture, respectively. The fact that the coalho cheese was commercialised with an official inspection seal did not influence the physicochemical, texture or colour analyses.
