| The reduction in time required to identify vancomycin-resistant enterococci (VRE) has gained increased importance during hospital outbreaks. In the present study, we implemented a laboratory protocol to speed up the VRE screening from rectal samples. The protocol combines a medium for selective VRE isolation (VREBAC®, Probac, São Paulo) and a multiplex PCR for detection and identification of vanA and vanB resistance genes. The screening performance was analyzed in 114 specimens collected from four intensive care units. The swabs were collected at two periods: (1) during a VRE outbreak (February 2006, n=83 patients) and (2) at the post-outbreak period, after adoption of infection control measures (June 2006, n=31 patients). Forty-one/83 VRE (49.4%) and... |

| Amebiasis is one of the twenty major causes of disease in Mexico; however, the diagnosis is difficult due to limitations of conventional microscopy-based techniques. In this study, we analyzed stool samples using polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) to differentiate between Entamoeba histolytica (pathogenic) and E. dispar (non-pathogenic). The target for the PCR amplification was a small region (228 bp) of the adh112 gene selected to increase the sensitivity of the test. The study involved 62 stool samples that were collected from individuals with complaints of gastrointestinal discomfort. Of the 62 samples, 10 (16.1%) were positive for E. histolytica while 52 (83.9%) were negative. No sample was positive for E.... |

| Swine leptospirosis is recognized world wide as an important cause of reproductive failure. Serum and histo-pathological examinations have been constantly used to diagnose this disease. This study was carried out on slaughtered sows from Northern Paraná State to compare serum findings with kidney, liver, ovary and uterus histo-pathological examinations. The microscopic serum-agglutination carried out on 36 animals detected 24 with titles > 100 and 12 negative (< 100). The histopathological examinations made on livers, kidneys, ovaries and uterus stained with hematoxylin-eosin, were carried out on 16 randomly chosen animals, 11 from the groups with > 100 serological titles and five from the negative group. The results showed that all the 16 animals... |

| M. hyorhinis is considered one of the etiological agents of arthritis in sucking pigs, but recently as seen, some strains can produce pneumonia that could not be distinguished from the mycoplasmosis caused by M. hyopneumoniae. The study was conducted to research the presence of Mycoplasma hyorhinis (M. hyorhinis ) in different regions of the country from exudates of pig lungs with typical EP lesions. Exudates from 280 pig lungs with typical EP lesions were studied using molecular techniques such as PCR, real time PCR and amplification of the 16S-23S rRNA. It was detected that the 66% of the samples studied resulted positive to M. hyorhinis, and the presence of this species was detected in all the provinces. Amplification and studies on the intergenic... |

| ABSTRACT: This study investigated the suitability of virus isolation (VI) in mouse neuroblastoma cells (N2A) and baby hamster kidney cells (BHK-21) as a confirmatory test for diagnosis of bovine rabies. Fourty-eight brain samples from cattle suspected of rabies were initially submitted to fluorescent antibody test (FAT) and mouse inoculation test (MIT) for routine diagnostic. Subsequently, these specimens were submitted to three protocols of VI in each cell line: a single 24h or 72h passage (T1, T2), or three 48h passages (T3). The FAT and MIT combined detected 32/48 positive samples, from which MIT detected 32 and FAT 31. The average time required for final MIT results was 12.3 days (8 - 21). VI in BHK-21 cells provided definitive, positive results in... |

| ABSTRACT: The present study aimed to investigate contagious agalactia (CA) in flocks from Pernambuco State. The study involved 225 goats and 63 ewes; 288 milk samples and 100 vaginal swabs were collected in total. The PCR assays were carried out using specific primers to Mycoplasma agalactiae and the Mycoplasma mycoides cluster. Among the goat’s milk samples,12.0% (27/225) were positive for Mycoplasma agalactiae DNA, while 5.3% (12/225) contained the Mycoplasma mycoides cluster. Of the vaginal swabs taken from goats, 15.4% (12/78) were positive for Mycoplasma agalactiae DNA and 3.8% (3/78) contained the Mycoplasma mycoides cluster. In the case of ewes, 4.3% (1/23) of the milk samples contained Mycoplasma agalactiae DNA, and 7.5% (3/40) were positive for... |

| Leptospira isolation allows definitive diagnosis of the infection. Contamination by microorganisms is one of the inconveniences of the culture. The objective of this study was to describe the isolation of Leptospira from dogs, bovine and swine naturally infected. Urine samples from 14 dogs and three bovines, and kidney, liver, ovary, and uterus body samples from 36 slaughtered sows with unknown health history, were used. The urine and organ samples were cultured in culture medium. Modified Ellinghausen-McCullough-Johnson-Harris medium (EMJH) culture medium was used with addition of 5-fluorouracil, chloramphenicol, vancomycin, nalidixic acid and neomycin. Incubation was performed at 28oC for 24 hours, followed by subculture in modified EMJH without... |

| ABSTRACT: Pythiosis in felines is a rare disease associated with the oomycete Pythium insidiosum. The aim of this report was to describe the macroscopic, histopathological, and molecular characteristics of P. insidiosum infection in a 2-year-old cat, with a localized invasive subcutaneous mass. The feline had an increase of volume near the anal region since it was younger. The cat died just after surgery. The necropsy was performed, and samples were collected for histopathological examination. Microscopically, the skin lesion was characterized by necro-eosinophilic dermatitis, panniculitis, and myositis surrounding negatively stained hyphal structures. In the sections stained with GMS, dark brown hyphae were clearly seen inside the affected tissue. They... |
