“…The monthly prevalence (66.6-100%) found in this study is similar to that observed in goats in the states of Acre (89%), Rio de Janeiro (70%), Minas Gerais (70%) (FACCINI & COSTA, 1992), and Paraíba (73%) (SANTOS et al, 2006a). However, in other northeastern states the prevalence reported for P. ovis was smaller: 37% in Bahia (BAVIA et al 1984(BAVIA et al /1985 and 36.2% for does, 41.7% for bucks, and 34.2% for kids in Ceará (COSTA & VIEIRA, 1984).…”

“…The increase in the infestation by P. ovis in goats during drier years and during the dry period of the year may be associated with the deficient nutritional state resulting from the scarcity of food during this period. Other factors, such as the agglomeration of animals in small places, the goat's physiological status (pregnancy), age, and stress may increase the susceptibility of goats to ectoparasites (SANTOS, et al, 2006a;LITTLEJONH, 1968). In this study, only 4.4% of goats presented mild to moderate clinical signs, in accordance with the classification of Littlejonh (1968).…”

“…In addition to the possible economic losses caused by the parasitism, P. ovis transmits mycoplasmas (COTTEW & YEATS, 1982;DAMASSA, 1990;SINCLAIR & FILAN, 1991), including Mycoplasma agalactiae, which is responsible for outbreaks of contagious agalactia in Paraíba (AZEVEDO et al, 2006) In northeastern Brazil, some goat ectoparasites, such as Bovicola caprae (SANTOS et al, 2006a) and P. ovis, (COSTA & VIEIRA, 1984) increase their population during the drier months, most likely due to poor nutrition due to reduced pasture and inadequate husbandry practices instead of the influence of abiotic factors. Despite its frequency, there is only one report, from the state of Ceará, on the seasonal fluctuation of P. ovis in goats in Brazil, which verified a rise in parasitism during the drier months of the year (COSTA & VIEIRA, 1984).…”

To determine the prevalence and seasonal variation of Psoroptes ovis (Delafond, 1858) mange in goats in the semiarid region of Paraíba, 541 crossbred goats of both sexes and different ages were examined between June 1999 and May 2001 and between August 2011 and December 2012, by washing their ear canals. The monthly prevalence of the infestation varied between 66.66% and 100% without significant differences (p = 0.10) among months and years. The intensity of infestation was higher between 2011-2012 (p < 0.05), with an annual rainfall of 123 mm, than between 1999-2000, which had an annual rainfall of 614.9 mm. By the Spearman test there was a negative correlation between the relative humidity and the rainfall of the intensity of the P. ovis infestation. It is concluded that parasitism by P. ovis occurs at a similar prevalence rate during the entire year but increases during dry years.Keywords: Mite, goats, prevalence, Psoroptes, semiarid. ResumoCom o objetivo de avaliar a prevalência e a flutuação sazonal da sarna por Psoroptes ovis (Delafond, 1858) em caprinos, na mesorregião do sertão paraibano, foram examinados, mediante lavagem dos condutos auditivos, 541 caprinos sem raça definida, de ambos os sexos e várias idades, nos períodos compreendidos entre junho de 1999 e maio de 2001 e entre agosto de 2011 e dezembro de 2012. A prevalência de P. ovis nos caprinos variou de 66,66% a 100%, não apresentando diferença estatística significativa (p = 0,10) entre os meses e entre os anos em que foi realizado o estudo. A intensidade de infestação foi maior no ano de 2011-2012 (p < 0,05) em comparação com o ano de 1999-2000. Pelo teste de Spermann (r 2 ), observou-se uma correlação negativa entre a umidade relativa e a precipitação pluvial com a intensidade de infestação por P. ovis. Conclui-se que o parasitismo em caprinos, na mesorregião do sertão paraibano, ocorre durante todo o ano, mas aumenta nos meses secos.

Image monitoring on the behavior study of three genetic groups of confined goats

et al. 2014

-The objective of this study was to analyze the behavior of three genetic groups of confined goats by image monitoring using nine unneutered goats of the Azul, Graúna and Moxotó genotypes. The experimental design was completely randomized, in a 3 × 3 factorial arrangement (genetic groups × periods -morning, afternoon and night), with three replications. Animals were monitored by video cameras placed at the ceiling of each stall for 10 days. There were interaction factors in the frequency of behavioral categories: interaction with the trough, self-cleaning, standing bipedally, social interaction, and other activities. Azul, Graúna and Moxotó native goats kept in the same environment under the same system of containment and feeding show different frequencies and durations in their behaviors, which are influenced by the period of the day.

The present study examined occurrences of ectoparasites and identified them on dogs in rural regions in Brazil, and assessed the influence of climate on these parasites. Ectoparasites were randomly collected from 194 dogs living on farms located in Lavras (n = 92) and Nanuque (n = 102) during the dry season. During the subsequent rainy season, the same dogs in Lavras (n = 71) and Nanuque (n = 66) were resampled. During the experiment, fleas, ticks, lice and fly larvae were collected. The flea species Ctenocephalides felis was the most common ectoparasite collected from these dogs. The main tick species that infested the dogs in rural areas of Nanuque and Lavras was Amblyomma cajennense. In Lavras, the dogs had high levels of flea infestation (80.4 and 88.7% in the dry and rainy seasons, respectively) and low levels of tick infestation (19.6 and 28.2% in the dry and rainy seasons, respectively), without any significant differences in infestation rates between the seasons. In Nanuque, moderate levels of flea infestation (68.6 and 43.9% in the dry and rainy seasons, respectively) and A. cajennense (65.7 and 47.0% in the dry and rainy seasons, respectively) were observed, with significantly lower prevalence in the rainy season (p < 0.05). The presence of ectoparasites was evident at both times of the year, but the different temperatures may have influenced the occurrences of parasites in Lavras and Nanuque.Keywords: Ectoparasites, tick, fleas, dog, rural regions, Brazil. ResumoO presente estudo examinou a ocorrência e identificação de ectoparasitas em cães de áreas rurais no Brasil, e a influência do clima sobre esses parasitas. Ectoparasitas foram aleatoriamente coletados de 194 cães provenientes de fazendas localizadas em Lavras (n = 92) e Nanuque (n = 102) durante o período seco. No período chuvoso subsequente, os mesmos cães de Lavras (n = 71) e Nanuque (n = 66) foram re-amostrados. Durante o experimento, pulgas, carrapatos, piolhos e larvas de diptera foram coletados. A espécie de pulga Ctenocephalides felis foi o ectoparasita mais comumente encontrado desses cães. A principal espécie de carrapato que infestava os cães nas áreas rurais de Nanuque e Lavras foi Amblyomma cajennense. Em Lavras, os cães tinham altos níveis de infestação de pulgas (80,4 e 88,7% nas estações seca e chuvosa, respectivamente) e baixos níveis de infestação por carrapatos (19,6 e 28,2% nas estações seca e chuvosa, respectivamente), não sendo observada diferença significativa nas taxas de infestação entre as estações. Em Nanuque, níveis moderados de infestação por pulgas (68,6 e 43,9% nas estações seca e chuvosa, respectivamente) e A. cajennense (65,7 e 47,0% na estação seca e chuvosa, respectivamente) foram observadas, com prevalência significativamente menor na estação chuvosa (p < 0,05). A presença de ectoparasitas foi evidente em ambas as épocas do ano, mas as diferentes temperaturas poderiam ter influenciado a ocorrência de parasitas em Lavras e Nanuque.
