| In 1995 and 1996, prices for weaned calves were at the lowest point for the current cattle market cycle. The National Animal Health Monitoring System (NAHMS) Beef ,97 Study examined the effects of the down market on beef cow-calf herd management practices. Most producers did not alter management practices in response to the down market. Among producers who made changes, costs were cut largely in the area of herd health management. Specific management practices in which costs were cut included decreases in use of vaccinations (7.4% of operations), herd medications (7.7% of operations), individual cow medications (5.0% of operations), and veterinary services (14.1% of operations). Other ways that producers altered management practices in response to the down... |

| This report presents a modeling framework in which epidemiological model results are integrated with an economic model of the U.S. agricultural sector to enable estimation of the economic impacts of outbreaks of foreign-source livestock diseases. To demonstrate the model, the study assessed results of a hypothetical outbreak of foot-and-mouth disease (FMD). The modeling framework includes effects of the FMD episode on all major agricultural products and assesses these effects on aggregate supply, demand, and trade over 16 quarters. Model results show a potential for large trade-related losses for beef, beef cattle, hogs, and pork, though relatively few animals are destroyed. The swine and pork sectors recover shortly after assumed export restrictions end,... |

| Due to a lack of national information about cull dairy cows, the USDA's National Animal Health Monitoring System (NAHMS) Dairy '96 Study investigated culling management practices. Operations included in the study represented 83.1 percent of U.S. milk cows. Most dairy cows were culled for reasons associated with their inability to profitably produce high-quality milk and calves; reasons for culling were not usually related to ill health or systemic disease. Results showed that almost all cull dairy cows in the US are intended for beef slaughter, as only about 4.4 percent were sent to other dairy operations. Nearly 77 percent of cows intended for beef slaughter were sent to markets, auctions, and sale barns, while 22 percent were sent straight to slaughter... |

| OBJECTIVE: To evaluate clinical, epidemiological and laboratorial aspects for the understanding of the disease characteristics and its relationship with diagnostic tests. METHODS: A retrospective, descriptive and analytical study involving 2,660 American cutaneous leishmaniasis (ACL) suspected patients from southern Brazil was undertaken between April 1986 and December 2005. Data on population characteristics and laboratory tests were obtained. Diagnostic laboratory tests used were direct search for Leishmania spp. (DS), Montenegro skin test (MST) and indirect immunofluorescent assay (IFA). RESULTS: 62.3% of patients were positive for at least one laboratory test. DS test was positive in 65.1%; MST in 92.3% and IFA in 70.0%. Although Cohen's Kappa test did... |

| Ventilator-associated pneumonia (VAP) is the most commonly-acquired infection in patients in intensive care units. We analyzed epidemiological and microbiological characteristics and the outcome, in a cohort of critically-ill patients with confirmed diagnosis of VAP. All patients who had been on mechanical ventilation (MV) for more than 48 hours were included in our study; material collection for microbiological analysis was done within the first 24 hours after beginning treatment or after changing antibiotics. There were 55/265 (20.7%) VAP cases diagnosed, at a rate of 21.6 episodes per 1,000 days of mechanical ventilation. Mean age of the patients was 66 years, with a mean APACHE II score of 26.7 + 7.0; male patients were more prevalent. The mortality... |

| In the few cases of acute childhood diarrhea that require antimicrobial therapy, the correct choice of the drug depends on detailed previous knowledge of local strains. In order to establish such parameters in our city, we reviewed the results of all 260 positive stool cultures of children between 0 and 15 years of age during two years at a pediatric tertiary care facility in Salvador, Brazil. Bacterial strains had been presumptively identified by culturing in selective media and by biochemical testing, and their antimicrobial susceptibility patterns were automatically detected by the MicroScan Walkaway System. Data about patients' sex and age, monthly distribution of the cases, pathogens isolated and their antimicrobial resistance patterns were recorded.... |

| The cat is becoming the most popular pet, especially due to people’s actual life style. This specie possesses peculiarities and requires different maintenance conditions, besides presents different clinical characteristics from other animals. Thus, a feline epidemiologic profile was traced using the medical records from the Veterinary Hospital of the University of Marília, in the period of 2007 to 2009. It was observed that out of the pets attended for, 8.62% were felines, of which 52.47% were female and 47.53% were male. As for breeds, 77.20% had undefined breeds, 14.83% were Siamese and 7.97% were Persians, with age ranging from 45 days to 26 years. The main affections diagnosed were divided in the areas of internal medicine and surgery, and classified... |

| OBJECTIVES: To compare epidemiological aspects of young (15 to 49 years old) and older (more than 50 years old) AIDS patients. METHODS: We analyzed 511,633 AIDS cases notified to the Brazilian Ministry of Health in the period of 1980-2008 looking at sex, age ranges, educational level and exposure category. Patients were divided into three age groups: under 15, from 15 to 49 and over 50 years old. Using a comparative approach, we analyzed data with regard to category of exposure, education (expressed in years of schooling), and sex ratio among younger (15-49) and older adults (over 50 years old). Time series data were log-transformed and normalized, and the temporal trend was evaluated. RESULTS: AIDS incidence is increasing among people over 50 years old in... |

| The aim of this paper was to study some epidemiological aspects of the infection by Brucella abortus in risk occupational groups in the microregion of Araguaína, Tocantins. For antibody research, 645 serum samples were analyzed by the complement fixation test (CF). A 4.0% frequency was found (26/645) in patients' serum and among those 4.1% (23/551) were slaughterhouses employees and 8.1% (3/37) rural workers. Of the total positive samples, three (2.0%) were women and 23 (4.7%) men; ten (2.9%) were between the ages of 18 and 30, six (3.4%) between 31 and 40, and nine (8.0%) were above 41 years of age. Risk factors for brucellosis in the study groups were age, background (OR = 2.45; CI 95% = 0.98 to 6.10) and previous work conducted with production animals... |

| Observou-se brucelose canina em quatro canis diferentes. Os canis apresentaram animais com história de aborto, mortalidade em neonatos e nascimentos prematuros. A porcentagem de animais soropositivos para brucelose canina, pela prova de imunodifusão em ágar gel, variou de 4,6 a 57,1%. Observou-se correlação positiva entre porcentagem de animais positivos e aspectos reprodutivos e condições de aglomeração. |
