The 21st Supply Deposit of the Brazilian Army (21st DSup), located in the city of São Paulo provides food raw materials for 16000 meals daily, and frozen fish is among the foodstuffs distributed. The objective of this study was to evaluate the good practices of seafood storage in the 21st DSup, identify issues of non-compliance that compromise food quality, and propose solutions. The system was evaluated, applying a checklist (RDC 275/2002) to evaluate the percentage of requirements in compliance with good practices. The 21st DSup was classified in Group 3, with 41% of items in conformance (< 50%), and we found that there is no hygienic-sanitary self-control program for storing cold seafood and other food supplies. The cold stores’ temperatures are not able to maintain products within the required standards of conservation. The seafood cold storage protocol of the 21st DSup does not guarantee temperature conformity. It is necessary to implement a hygienic-sanitary self-control program for food supply storage, which should begin with the development of a food safety culture.

Several studies show the presence of protozoa of the genus Nematopsis Schneider, 1892, in many species of bivalves. The pathogenicity of this Apicomplexa is still much debated, which is possibly related to the parasitism degree and host habitat. In this context, this study investigated parasitism by Nematopsis sp. in Mytella guyanensis (Bivalvia: Mytilidae) in a mangrove of the Marine Extractive Reserve Baía do Iguape, Bahia, Brazil. The collections were made monthly, from March 2014 to March 2015, consisting of 30 adults with shell height above 40 mm per month, totaling 360 specimens. The specimens were measured, weighed, opened, and macroscopically examined for identifying parasites and/or signs of morphological changes. After that, they were fixed in Davidson’s solution and processed according to classical histological techniques, with inclusion in paraffin, obtaining 5 μm-thick sections by microtomy, and stained by Harris’ Hematoxylin and Eosin (HE). The water temperature ranged from 25.5 to 33.6 ºC and the salinity from 21.1 to 34.3 Practical Salinity Units (PSU). The specimens measured between 41.1 and 68.6 mm and had an average weight of 7.24 g. Macroscopically, there was no presence of the parasite or any morphological changes related its presence. The frequency percentage of Nematopsis sp. was 99.45%. The mantle was the organ with the highest frequency of infection (46.26%), followed by the gonads (18.36%). Among the analyzed organs, all presented the parasite and, in a few severely infected cases, microscopical changes were observed in the mantle conformation. The infection intensity for most of the sessions analyzed was 1 to 3 oocysts/phagocyte; however, in one of the sessions, 9 oocysts/phagocytes were recorded. The parasite had a negative correlation with salinity. The high frequency of Nematopsis sp. should be considered for the sustainability of natural stocks, especially if such parasitism occurs simultaneously with other pathogens and stressful environmental conditions.

O frênulo peniano é uma fina faixa de tecido conectivo que une a glânde ao prepúcio que pode se romper sob a ação da testosterona quando o animal inicia a puberdade. Devido a escassez de relatos desta afecção o presente trabalho relata a ocorrência de frênulo peniano persistente em um gato doméstico, sem raça definida, de sete meses de idade e 5,2 kg. O frênulo peniano foi um achado incidental durante o exame clínico do animal. O animal já apresentava‑se em puberdade, caracterizando o quadro de frênulo peniano. A resolução do caso ocorreu de maneira espontânea previamente a orquiectomia eletiva. Dessa forma, as alterações observadas no pênis devido a alteração congênita em gatos são descritas neste relato.

Previous studies have reported on the phytotherapeutic potential of propolis from southern Brazil (Urupema, Santa Catarina State), in particular, its efficacy in the treatment of bovine mastitis. The present study evaluates the effect of seasonal variation on the chemical composition of propolis from southern Brazil and its resultant antimicrobial and cytotoxic activities in the context of treating bovine mastitis. Antimicrobial activity against Staphylococcus aureus was assessed, along with the cytotoxicity and induction of apoptosis in MAC-T bovine mammary epithelial cells. With the exception of spring propolis, the flavonoid quercetin was the main compound present in all samples. The minimum inhibitory concentration (MIC) of propolis against S. aureus from mastitic milk was 140 μg/mL for samples collected during the spring, autumn, and winter seasons, but 280 μg/mL for samples collected in summer. For MAC-T cells, the spring propolis extract was more toxic with an IC50 of 120 μg/mL. However, for 120 μg/mL of spring propolis extract, only 0.77% of necrotic and 37% of apoptotic MAC-T cells were found, respectively. Nonetheless, the induction of cell deaththrough apoptosis by propolis extract suggests less severe damage to bovine mammary glands. Moreover, only negligible seasonal variation was found in the chemical composition of propolis from southern Brazil, and no biological activities were determined to be harmful. Therefore, this propolis shows promise as an alternative to commercial antimicrobials in the control of bovine mastitis, offering support for organic milk production.

Equine ocular Setariasis is a vision threatening disease of equine, caused by Setaria spp. This clinical communication describes two equine ocular Setariasis cases which were successfully treated with a single dose of ocular Ivermectin injection. Two ponies were referred to the Ambulatory clinic, Faculty of Veterinary Medicine, Peradeniya, Sri Lanka with the complaint of observation of a moving worm inside the anterior chamber of the eye since few days. The cloudiness of the cornea has been gradually increasing since the day the owner observed the worm inside the eye. Upon the clinical examination, both ponies were normal except the signs related to the eye condition including extent lacrimation, and moderate, unilateral corneal opacity. On close examination of the affected eye, the swirling movements of white thread like worm swimming continuously in aqueous humor of anterior chamber of the eye was evident in both cases. The ponies were properly restrained. 0.05ml of 1% ivermectin was loaded in to a sterile 1cc syringe with a 29G needle and was double diluted with normal saline. While the pony’s head was held firm, the needle was inserted in to the anterior chamber of the eye and the drug was released slowly. Prophylactic eye ointment containing an antibiotic i.e. 3% Tetracycline Hydrochloride (Galentic®) ointment was prescribed to be applied in the eye twice daily. Within an hour after the ivermectin treatment, the movements of the worm became sluggish and the movements were restricted to the most ventral part of the anterior chamber. The worm which was in the anterior chamber died on the same day of treatment. But few days later, the dead worms had triggered an inflammatory reaction in the eye, thus the animals were treated with an ophthalmic preparation containing NSAID i.e. 0.5% Ketorolac Tromethamine (Ketrosan®) ophthalmic solution. The condition recovered without any impairments of the vision or damages to the eye. Treatment of ocular Setariasis is always being a challenge. There are reported cases of successful surgical and medical interventions for ocular Setariasis in equids. This method would provide a less invasive, quick method done using only a single dose of ocular ivermectin injection in order to treat equine ocular Setariasis.

Mastitis is the most costly disease of dairy cows. A pro-active approach includes insuring adequate levels of selective trace minerals. The aim of this study was to determine the effect of two different commercially available, injectable selenium products, (sodium) Na-selenite (inorganic) and (selenium) Se-methionine (organic), on milk composition and on serum and milk selenium concentrations in high-yielding Holstein cows on total mix ration. Sixty multiparous cows were randomly selected into three groups of 20, one control group and two groups supplemented with injectable trace minerals. Blood and milk samples were collected over a period of 60 days. No specific change was indicated in milk yield, lactose, milk urea nitrogen (MUN) and milk pH levels compared with baseline values. The Se-methionine supplemented group showed a numerical increase in total milk protein percentage. In the group injected with Se-methionine, a negative correlation was present for the initial 72 hours between serum selenium concentration and somatic cell count (SCC) and a highly significant (p 0.001) increase in milk selenium concentration for the initial 24 hours. Serum selenium concentration of Se-methionine-supplemented cows was however not significantly changed. Injection of Na-selenite led to a 60-day initial increase in serum selenium concentration above baseline levels and a significant milk selenium concentration on day 1 but to a negative correlation between serum selenium concentration and SCC. Differences in serum and milk selenium concentrations followed with the use of organic and inorganic selenium injectables. Injectable Na-selenite, as selenium, can be of important value for cattle farmers if supplemented on strategically physiological periods to improve production, reproduction and immunity.

Akabane virus, a member of the Orthobunyavirus genus in the family Bunyaviridae, causes congenital abnormalities and arthrogryposis with hydrocephalus or hydroencephaly in ruminants. Tis study intends to describe the clinical signs, gross and histopathological features seen in 25 afected lambs in an outbreak of congenital arthrogryposis with hydrocephalus or hydranencephaly in Al-Muthanna governorate, Iraq afer a large number of stillbirths and musculoskeletal deformities from October 2017 to May 2018. Skeletal muscle hypoplasia was seen in the limbs of the afected lambs accompanied with severe arthrogryposis and gross visible brain malformations. In addition, fetal mummifcations, stillbirths, and dead lambs were also seen. Te most histopathological features in muscle fbers were degenerative lesions and absences of cross-striation accompanied with mild infltration of neutrophils and mononuclear cells in severely afected lambs. Te meninges of afected lambs revealed fused membranes with focal areas of fbrous thickenings and necrotic debris. In conclusion, according to clinical signs, gross and histopathological investigations, Akabane virus, a member of the Orthobunyavirus genus in the family Bunyaviridae, causes congenital abnormalities and arthrogryposis with hydrocephalus or hydroencephaly in ruminants and could be the cause of this outbreak, although future studies must be performed to confrm the etiology of this outbreak. Moreover, other causes of hydrocephalus or cerebellar malformation, such as Schmallenberg virus, bluetongue virus and border disease virus and teratogenic plants that lead to arthrogryposis, have to be investigated. Also, the authorities should take prevention and control measurements to stop the replication of arthropod vectors.

The aim of the present study is to investigate the effect of virgin olive oil on some blood parameters in male Albino rats supplemented with normal diet. thirty male Sprague Dawley rats, (90-110 g), were used in the present study, and were divided into three groups (10 in each), 1st group (control), received basal diet and supplemented with 1ml saline. 2nd and 3rd groups received basal diet, and supplemented daily with 1ml/100 gm B.W and 2ml/100 gm B.W of virgin olive oil (VOO), respectively for 4 weeks. Blood samples were collected weekly from all rats. Serum samples was obtained for assay of lipid profile levels and hepatic lipid peroxidation (MDA) enzyme. Blood lysate was used for antioxidant enzymes activities SOD, GPx and CAT.

E coli infection in poultry is one of the principle causes of mortality and morbidity in chickens and turkeys resulting in retardationof growth and decreased feed conversion rate . The most common form of collibacillosis is characterized as an initial respiratoryinfection (air sacculitis) followed by generalized septicemia, perihepatitis and pericarditis. The present study aimed to identify thebacteria associated with pericarditis , airsacculitis and perihapatitis in Egyptian broiler chickens. A total 300 samples of diseasedand dead broilers from 3-6 weeks age were collected. The isolated bacteria included E. coli, Klebsiella spp., Shigella spp. AndEnterobacter spp. Sero-grouping of the isolated E. coli strains revealed O125, O158, O55,O129, O20 , O6 , O8 , O27, O115,O142 and un-typed strains with prevalence of 16%, 12%, 8%, 8%, 8% , 8% , 8% , 8% ,4%,4% and 16% respectively. Themajority of E coli isolates were sensitive to colistin sulphate (38%) and Norofloxacin (38%) followed by ciprofloxacin (19%),cefotaxim (19%) and Ofloxacin (19%). On the other hand, E coli were resistant (100%)to amoxicillin, clindamycin ,Erythromycin and streptomycin. PCR analysis for antibiotic resistance genes of E coli detected that 12 serogroups isolates werepositive using the specific primers for Aada2 , BlaCTX and TetA(A) genes. The current study demonstrated the high prevalenceof E. coli indeed broilers suffered from pericarditis , perihepatitis and airsacculitis . Measures are needed to control E. colicontamination in poultry farms to reduce economic losses caused by infection of E.coli.

African trypanosomes are etiological agents of trypanosomosis transmitted by tsetse flies (Glossina spp). Thus, identifying them in vectors and hosts together with their classification into species, subspecies is crucial for effective control of the diseases they cause to animals and human. This study analysed 350 samples collected from cattle (100) and tsetse flies (250) of Meatu district for identification of trypanosomes through amplification of Internal transcribed spacer 1 (ITS-1) region in order to support formulation of tsetse and trypanosomosis control strategies within the district. Occurrence of trypanosomes in cattle was 15%, while in tsetse was 1.20%. Trypanosoma congolense was identified in cattle whereas; T. simiae and T. godfreyi were identified in tsetse flies. The tsetse and trypanosomosis control options were discussed.
