Caseous lymphadenitis (CLA) caused by the pathogenic bacterium, Corynebacterium pseudotuberculosis, results in economic loss in goat farming. Its prevalence in Brazilian herds varies from 5 to 50%, generating expenses with treatment, loss in production, carcass and organ condemnation, and reduced price of the hide. This study aimed to describe the distribution of lesions and quantify the loss associated with CLA in goat breeding due to condemnation in a slaughterhouse located in a semiarid region. The study was conducted at the municipal slaughterhouse of the city of Patos, State of Paraíba, Northeastern Brazil, where goats from this intermediate geographical region are slaughtered. In 2017, 3,662 animals were slaughtered, an average of 305 per month. During the study period, from March to August 2017, 304 goats of both sexes and different ages of undefined breed were assessed. In the ante-mortem examination, inspection and palpation of the superficial lymph nodes was done; in the post-mortem examination, organ and viscera were assessed. The caseous material collected was sent for microbiological analysis. Of the 304 individuals, 227 [74.67% (95% CI: 69.50-79.23)] did not have any lesions, while 77 [25.33% (95% CI: 20.77-30.50)] showed abscesses suggestive of CLA, which was confirmed in 65 goats [84.41% (95% CI: 76.30-92.50)]. Sex (P = 0.044) and age (P = 0.002) were associated with infection. While the sex of the animals affected carcass and viscera weights and carcass yield, their age affected live weight, carcass, organ, and viscera weights; conversely, the incidence of CLA did not affect these variables. The average price in Real (R$) of a kilogram (kg) of goat meat cuts and "offal" was used to calculate the economic loss. Considering the average carcass weight (11,485 kg), organ weight (1,085 kg), and viscera weight (2,013 kg), 4,433.232 kg of meat was produced, resulting in R$ 72,945.43. The condemnations resulted in the loss of 269.894 kg, which is equivalent to R$ 4,540.33. CLA is responsible for a negative impact of 6.09% on production. Implementing control measures for this disease is important to increase the financial return in goat farming.

Over two million tonnes of fertiliser are applied to New Zealand pastures and crops annually and there is an increasing desire by farmers to ensure that the best possible economic return is gained from this investment. Spreading distribution measurements undertaken by Lincoln Ventures Ltd (LVL) have identified large variations in the evenness of fertiliser application by spreading machines which could lead to a failure to achieve optimum potential in some crop yields and to significant associated economic losses. To quantify these losses, a study was undertaken to calculate the effect of uneven fertiliser application on crop yield. From LVL's spreader database, spread patterns from many machines were categorised by spread pattern type and by coefficient of variation (CV). These patterns were then used to calculate yield losses when they were combined with the response data from five representative cropping and pastoral situations. Nitrogen fertiliser on ryegrass seed crops shows significant production losses at a spread pattern CV between 30% and 40%. For P and S on pasture, the cumulative effect of uneven spreading accrues, until there is significant economic loss occurring by year 3 for both the Waikato dairy and Southland sheep and beef systems at CV values between 30% and 40%. For nitrogen on pasture, significant loss in a dairy system occurs at a CV of approximately 40% whereas for a sheep and beef system it is at a CV of 50%, where the financial return from nitrogen application has been calculated at the average gross revenue of the farming system. The conclusion of this study is that the current Spreadmark standards are a satisfactory basis for defining the evenness requirements of fertiliser applications in most circumstances. On the basis of Spreadmark testing to date, more than 50% of the national commercial spreading fleet fails to meet the standard for nitrogenous fertilisers and 40% fails to meet the standard for phosphatic fertilisers.Keywords: aerial spreading, crop response, economic loss, fertiliser, ground spreading, striping, uneven application, uneven spreading, yield loss

Toxic Blooms

We report the occurrence of cyanobacterial blooms and the presence of cyanotoxins in water samples from the Armando Ribeiro Gonçalves reservoir (06° 08’ S and 37° 07’ W), located in the state of Rio Grande do Norte, in the semiarid region of northeastern Brazil. The cyanobacterial species were identified and quantified during the rainy and dry seasons in the year 2000. Cyanotoxins such as microcystins, saxitoxins and cylindrospermopsins were analyzed and quantified using HPLC and ELISA methods. The mixed toxic blooms of Cylindrospermopsis raciborskii, Microcystis spp (M. panniformis, M. protocystis, M. novacekii) and Aphanizomenon spp (Aphanizomenon gracile, A. cf. manguinii, A. cf. issastschenkoi) were persistent and represented 90-100% of the total phytoplankton species. Toxic cyanobacterial blooms from the Armando Ribeiro Gonçalves reservoir were analyzed and found to have three phases in relation to the annual cycle. During the rainy season, an intense toxic bloom of Cylindrospermopsis raciborskii was recorded along with saxitoxins (3.14 µg.L-1). During the transition period, between the rainy and dry seasons, different species of Microscytis occurred and microcystin as high as 8.8 µg.L-1 was recorded. In the dry season, co-dominance of Cylindrospermopsis raciborskii, Microcystis spp and Aphanizomenon spp occurred and the concentrations of saxitoxin remained very low. Our results indicate the presence of microcystins (8.8 µg.L-1) and saxitoxins (3.14 µg.L-1) into the crude water, with increasing concentrations from the second fortnight of April to late May 2000. The occurrence of toxic blooms in this reservoir points to a permanent risk of cyanotoxins in supply waters, indicating the need for the implementation of bloom control measures to improve the water quality. Exposure of the local population to cyanotoxins through their potential accumulation in fish muscle must also be considered.

Chicken Eggs

Background: Food contamination is an important and growing public health concern due to the risk of foodborne illnesses. In this context, the egg, consumed all over the world, stands out. This food has been pointed out as a carrier of several bacteria, causing outbreaks of food toxinfection. The production of free-range chicken eggs (Gallus gallusdomesticus) has been an alternative for generating income for producers in Brazil; however, there is no monitoring of the sanitary quality of this product. The objective of this study was to identify microorganisms in 128 free-range chicken eggs sold in open markets in the semiarid region of Northeastern Brazil.Discussion: The frequency of bacterial isolation obtained in this study was high and reflects contamination of the eggs, which can occur through the shell, and factors such as air humidity, time and temperature favor the migration of bacteria from the shell to the internal content of egg. Food toxinfection occurs due to improper conditions in food processing, and it is essential to guarantee correct handling, promoting health quality. Therefore, some care related to egg management is necessary, from primary production to commercialization, ensuring food safety for consumers. Another point to be highlighted concerns the way of marketing this product. Eggs from free-range chickens are usually sold in open markets, kept at room temperature from production to final distribution, mainly in the semiarid region of Northeastern Brazil. Temperature, storage time and chicken’s characteristics (lineage, age, nutritional management and health status) are factors that have a direct influence on the quality of the food offered to the consumer. The high frequency of isolated bacteria warns of the implementation of control measures to avoid contamination of this product and the importance of the correct use of antimicrobials in poultry, in order to avoid the spread of resistance-carrying pathogens, minimizing economic, health and environmental impacts.

Abstract This study aimed to determine the seroprevalence, factors associated with seropositivity to Leishmania infection in dogs and spatial analysis in six municipalities in the semiarid region of Pernambuco, Brazil. Blood samples were collected from 462 dogs, 77 in each municipality, and used for serological analysis [dual path platform (DPP®) and enzyme-linked immunosorbent assay (ELISA)]. Clinical signs of dogs were evaluated and associated factors for Leishmania infection were analyzed using robust Poisson regression model. A seroprevalence of 42.8% (198/462, IC: 95% = 38.6%-47.6%) was detected in dogs that tested positive in both tests, ranging from 29.8% to 55.8%, with higher prevalence in the municipality of Cabrobó (55.8%; P = 0.006). About 67% (132/198) of the seropositive dogs showed one or more clinical signs suggestive of canine leishmaniasis (CanL), such as lymphadenomegaly, skin lesions and conjunctivitis, which were associated with seropositivity. High seroprevalence levels were identified in urban and rural areas in all the municipalities, and the buffer for sand flies around cases covered almost these entire areas. Spatial analysis revealed a significant cluster, showing a relative risk of 1.88 in the urban area of Cabrobó. The higher density of seropositive dogs in urban areas indicates the need effective control measures against CanL to prevent the emergence of canine and human diseases.

Constriction cankers, caused by Phomopsis amygdali, girdle and kill fruiting twigs which results in a direct crop loss. To quantitatively determine this loss from 1996 to 1998, the number of fruit lost per infected shoot was estimated as a function of disease incidence in 21 severely infected orchards in New Jersey. For each cultivar in 1997 and 1998, the distribution of fruit sizes at harvest and prices at shipping were used to calculate total crop value for typical expected yields. Economic loss was then calculated from yield loss and crop value estimates. The overall percent yield loss mean across all sites and cultivars, unadjusted for fruit remaining on infected shoots, was 22.2, 30.7, and 23.7% for 1996, 1997, and 1998, respectively. The frequency of these losses were not normally distributed, and the nonparametric Friedman test indicated that yield loss was significantly different among years. Assuming the remaining fruit on infected shoots were harvested, yield losses for 1997 and 1998 were 28.5 and 21.0%, which translated into average economic losses of $4,009 and 2,803/ha, respectively, for an expected yield level of 14,010 kg/ha. These loss values justify control measures for management of constriction canker in severely infected orchards.

This paper reports the occurrence and epidemiology of outbreaks of foot rot and other foot diseases in goats and sheep in the semiarid region of Paraíba, northeastern Brazil. Four farms were inspected for the presence of foot lesion in sheep and goats and for environmental conditions, general hygiene, pastures, and disease control measures. The prevalence of foot lesions was 19.41% (170/876) in sheep and 17.99% (52/289) in goats, ranging between 5.77% and 33.85% in different farms. Foot rot was the most common disease, affecting 12.1% of the animals examined (141/1165), but with significantly higher (p<0.05) prevalence in sheep (13.69%) than in goats (7.27%). The frequency of malignant foot rot was also significantly lower (p<0.05) in goats (9.53%) than in the sheep (40.83%). On one farm, Dorper sheep showed significantly higher (p<0.05) prevalence of foot rot (17.5%) than Santa Inês sheep (6.79%), and the number of digits affected was also higher in the former. Dichelobacter nodosus and Fusobacterium necrophorum were isolated from cases of foot rot. White line disease was found in 3.95% of the animals, sole ulcers in 1.29%, foot abscess in 1.03% and hoof overgrowth in 0.5%. The high rainfall at the time of occurrence, grazing in wetlands, clay soils with poor drainage, presence of numerous stony grounds, closure of the flocks in pens at night, and introduction of affected animals were considered predisposing factors for the occurrence of foot diseases.

Background: Histomoniasis is a disease caused by Histomonas meleagridis, a flagellated protozoan that can cause severe necrotizing hepatitis and typhlitis in several bird species. The disease has a cosmopolitan distribution. In experimental infection, peacocks (Pavo spp.) showed susceptibility to histomoniasis, however there are few reports on natural histomoniasis in this species. In northeastern Brazil, reports about its occurrence in avian species are scarce and nonexistent in peacocks. Therefore, this report aims to describe the epidemiological and clinicopathological aspects of a histomoniasis case in a peacock (Pavo cristatus) in the Brazilian semiarid region.Case: A 3-month-old male peacock with a history of apathy and anorexia was attended in the Veterinary Hospital of the Universidade Federal Rural do Semi-Árido (UFERSA), Mossoró, RN, Brazil. The animal was raised extensively in a farm without basic sanitary measures, also with a history of living with animals of different species. After clinical examination, in which intense apathy and weight loss were confirmed, the bird was submitted to emergency therapeutic measures, however there was no clinical improvement and the bird died. At necropsy, intense diffuse bilateral necrotizing typhlitis and multifocal to coalescent necrotizing hepatitis were observed. Fragments of the organs were collected in 10% formaldehyde buffered with phosphate-saline buffer for histopathological analysis and cecal content were collected for microbiological analysis. Histopathology of the cecum revealed transmural necrotizing typhlitis associated with myriads of trophozoites morphologically compatible with Histomonas meleagridis. The same microorganisms observed in association with necrotizing hepatitis lesions, which allowed the diagnosis of histomoniasis. Also, the bacterium Pantoea agglomerans was isolated from the cecal content.Discussion: The macroscopic and microscopic findings allowed the diagnosis and the first recording of histomoniasis in peacock in the semi-arid region of Rio Grande do Norte. The bird was raised in an extensive breeding and without sanitary management, such as the use of anthelmintics, which may favor infection by the nematode Heterakis gallinarum, that’ transmits the protozoan Histomonas meleagridis. The contamination, which begins by the orofecal route, happens through the ingestion of eggs of the nematode contaminated with H. meleagridis that pass through the gastrointestinal tract, reaching the ceca and causing intense lesions in the organ, such as the bilateral transmural typhlitis that we observed in this case. From ceca, the protozoan has access to the bloodstream and reaches the liver, where it causes necrotic hepatitis, also present in the peacock. Both cecal and hepatic lesions were associated with myriads of microorganisms morphologically compatible with H. meleagridis, which allowed the diagnosis of the disease. The challenge in diagnosing this disease occurs mainly due to nonspecific clinical signs, such as apathy and weight loss, the only signs reported by the breeder and observed in this peacock. Confirmation of the occurrence of histomoniasis in any region is important to establish the disease among the differential diagnoses for the species, as in this case. Since this is the first report of peacock histomoniasis in the semi-arid region of Rio Grande do Norte, it is evident the need to consider the disease among possible diagnoses in cases of nonspecific symptoms and it also demonstrates the need to implement control and prophylaxis measures in peacock breeding aiming to avoid losses of birds and economic losses to the breeders and to promote quality of life to the animals.

Loss in the supply chain of small ruminants owing to condemnations of carcasses in the abattoirs and slaughterhouses is common in northeastern Brazil. This study aims to identify bacterial agents, including Mycobacterium spp., in the abscesses found in the postmortem analysis of the carcasses of sheep and goats bred in northeastern Brazil. Our analysis involved 679 goats and 1,838 sheep carcasses. Abscess samples were extracted and inoculated on blood agar and Lowenstein Jensen with pyruvate or glycerol for bacterial isolation. We then performed polymerase chain reaction of the hps 65 gene; samples positive for Mycobacterium spp. were subjected to DNA sequencing. Relative frequencies of abscesses in goats and sheep were 5.44 and 3.26%, respectively. Microbiological analysis revealed 87.7% bacterial growth in the inoculated samples. Among these, Corynebacterium pseudotuberculosis represented 67.7% of the isolates. We observed 1.9% mycobacteria growth in the abscess samples inoculated on Lowenstein-Jensen medium. PCR of DNA extracted from abscesses samples showed amplification of 0.9% of samples. After sequencing, Mycobacterium spp. isolate was identified as M. novocastrense. C. pseudotuberculosis was the main agent responsible for the formation of abscesses in the examined animals, and we did not identify any species of the M. tuberculosis complex in the examined small ruminants.

Caseous lymphadenitis is one of the main concerns in the health management of sheep and goats and, therefore, this work sought to identify the occurrence of this disease in herds in the metropolitan region of Manaus - AM. Visits were made to seven properties, collecting data through investigative questionnaires, physical examinations on 562 animals and microbiological analysis of the samples. Caseous lymphadenitis was observed in 1.78% (10/562) of the animals evaluated, where five (0.89%) of the animals presented reactive lymph nodes and five (0.89%) presented healing processes suggestive of lymphadenitis. Despite the low prevalence in the region, it was noted that there is a need for the dissemination of good agricultural practices and sanitary management in sheep and goat farming in the region.
