Veterinary sanitary assessment of mutton after application of antihelminth feed additive with albendazole / Avaliação sanitária veterinária de carneiro após aplicação de aditivo anti-helmíntico com albendazol

Abstract This study assessed the anthelminthic feed additive albendazole effect on the main indicators of the quality of sheep meat obtained from infected and deworming animals. A total of 20 heads of Akzhaik meat and wool sheep (i.e. 2 years of age, of different sex) were used in a 20-day experiment and 2 groups of 10 heads were formed (n = 4). The sheep were fed with the basic diet (i.e. control, group CON), without adding anything, and the second group was fed the basic diet orally with the addition of a dose of 1.2 g / head (an experimental group). At the end of the experiment, a control slaughter was carried out from each group in order to study the biochemical composition of meat and its quality. The anthelmintic feed additive albendazole did not have a significant effect on the indicators (organoleptic and physicochemical) of meat quality (P> 0.04). However, the ratio of fat and ash in the meat of the control group has differences in indicators and is reduced by 24.81% and 0.03%, respectively. The drug had a significant effect on the biological value of meat in the experimental group, where there is a higher content of essential amino acids (P = 0.06), nonessential (P = 0.05) concentrations in comparison with the CON groups. The results obtained show that the meat of the experimental groups of sheep, when using the anthelminthic feed additive albendazole, did not have a significant effect on organoleptic parameters, but significantly positively influenced the metabolism, live weight gain and biological value of meat.

Resumo Este estudo avaliou o efeito do aditivo anti-helmíntico albendazol sobre os principais indicadores de qualidade da carne ovina obtida de animais infectados e desparasitados. Um total de 20 cabeças de carne Akzhaik e ovelhas de lã (ou seja, 2 anos de idade, de sexo diferente) foi usado em um experimento de 20 dias e dois grupos de 10 cabeças foram formados (n = 4). As ovelhas foram alimentadas com dieta básica (ou seja, controle, grupo CON), sem adicionar nada, e o segundo grupo foi alimentado com dieta básica por via oral com a adição de uma dose de 1,2 g / cabeça (um grupo experimental). Ao final do experimento, foi realizado um abate controle de cada grupo para estudar a composição bioquímica da carne e sua qualidade. O aditivo anti-helmíntico albendazol não teve efeito significativo sobre os indicadores (organolépticos e físico-químicos) de qualidade da carne (P > 0,04). No entanto, a proporção de gordura e cinzas na carne do grupo de controle tem diferenças nos indicadores e é reduzida em 24,81% e 0,03%, respectivamente. A droga teve efeito significativo sobre o valor biológico da carne no grupo experimental, onde há maior teor de aminoácidos essenciais (P = 0,06), concentrações não essenciais (P = 0,05) em comparação com os grupos CON. Os resultados obtidos mostram que a carne dos grupos experimentais de ovinos, ao utilizar o aditivo anti-helmíntico albendazol, não teve efeito significativo nos parâmetros organolépticos, mas influenciou positivamente de forma significativa no metabolismo, ganho de peso vivo e valor biológico da carne.

Pulmonary Hydatid without Liver Involvement: A Case Series

Pulmonary hydatid is not a rare disease. But raising a suspicion for its diagnosis is limited. There are limited approaches for the diagnosis and treatment of the same. We present here four cases of pulmonary hydatid, without liver involvement, with emphasis on how it was misdiagnosed and received multiple treatment and landed into complications. Most of our cases presented with cough, sputum and hemoptysis. For these nonspecific signs and symptoms, patient is generally treated on a different line of diagnosis. Two of the cases were already treated for abscess and fungal infection. One of the patients was on antitubercular treatment. One of our cases was secondarily infected with aspergilloma. One of the cases was referred to oncologist to start chemotherapy. Interestingly, to raise a suspicion, none of our cases had liver involvement. A detailed history revealed expectoration of white salty material in sputum, living with sheep and dog and expectorating grape-like vesicles in sputum. History helped us to put hydatid as one of our differentials. Echinococcal serology was positive in three cases. Only three cases had on-table appearance of hydatid cyst. All four cases underwent surgical management for complete cure. There is need for strong suspicion and a detailed history and proper set of investigations help in timely diagnosis and management of pulmonary hydatid disease.

Mielopatía dorsal aguda como presentación atípica de una neurocisticercosis espinal

La neurocisticercosis espinal es una enfermedad infecciosa poco frecuente. Su presentación puede ser extraespinal o intraespinal y la mayoría de casos es de evolución subaguda o crónica. Se presenta el caso de una paciente mujer de 55 años, natural y procedente de Lima, Perú, con cuadro clínico de una paraparesia aguda secundaria a una mielopatía dorsal por lesiones quísticas de cisticercosis espinal. La paciente recibió tratamiento médico y quirúrgico con una evolución clínica y de imágenes favorable. Es importante considerar en nuestro contexto epidemiológico, la cisticercosis espinal como diagnóstico diferencial, ante un cuadro clínico de mielopatía aguda, ya que el adecuado enfoque diagnóstico y tratamiento oportuno de esta rara entidad pueden mejorar el pronóstico de los pacientes.

Spinal neurocysticercosis is an infectious and rare disease. Its presentation can be extraspinal or intraspinal and most cases are of subacute or chronic evolution. We report the case of a 55-year-old female patient from Lima, Peru with a 2-day history of acute paraparesis secondary to dorsal myelopathy due to cystic lesions of spinal cysticercosis. The patient received medical and surgical treatment with a favorable clinical and imaging evolution. In our epidemiological context, it is important to consider a spinal cysticercosis as a differential diagnosis when faced with a clinical picture of acute myelopathy, since the appropriate diagnostic approach and timely treatment of this rare entity can improve the prognosis of patients.

Progress of researches on albendazole for treatment of alveolar echinococcosis / 中国血吸虫病防治杂志

Alveolar echinococcosis, caused by Echinococcus multilocularis infection, is a highly deadly zoonotic parasitic disease. As a benzimidazole compound, albendazole has a strong and broad-spectrum anti-parasitic action. For alveolar echinococcosis patients that are unwilling to receive surgical treatment, lose the timing for surgery, or are intolerant to surgery due to poor physical status, administration of albendazole may delay disease progression. Recently, a large number of advances have been achieved in experimental studies on alveolar echinococcosis. In order to increase the understanding of the therapeutic efficacy of albendazole for alveolar echinococcosis, this review summarizes the advances in albendazole treatment for alveolar echinococcosis, so as to provide insights into the clinical treatment of alveolar echinococcosis with albendazole.

Analysis of the effect of in vitro dissolution on the pharmacokinetics of albendazole

Abstract Albendazole is an anthelmintic drug commonly used in parenchymal neurocysticercosis and cystic echinococcosis. The aim of this study was to explore whether disparities in the dissolution profiles of albendazole products lead to significant differences in pharmacokinetic parameters. Three generic products and the innovator were evaluated in vitro. Quality control tests were performed, and dissolution profiles were obtained according to the Mexican Pharmacopeia. Although all products passed the quality control tests, none of the generic products complied with the similarity factor (f 2). The product with the lowest f 2 value in respect to the reference was chosen for in vivo evaluation. The study was carried out in 12 healthy volunteers who received 400 mg of the generic or reference product according to a crossover design. No significant differences were found in Cmax and AUC for albendazole and its main metabolite, albendazole sulfoxide, between products. Two absorption peaks were observed in the pharmacokinetic profile, and a population (22%) with different absorption rates and delay time for the the second peak was found. Based on the results, due to the high variability in the absorption process the differences observed in vitro could not be observed in vivo.

Hydatid Disease — An Overview

Human Hydatid Disease is a growing menace, a parasitic disease present in many countries all over the globe (more than 1 million people are affected throughout the World annually). Tape-worm is the main causative organism.In humans it is prevalent in two forms – Cystic Echinococcosis (CE) [caused by Echinococcus granulosus] and Alveolar Echinococcosis (AE)[caused by Echinococcus multilocularis]. Humans are the accidental intermediate host; they are being affected by drinking water or eating food contaminated with parasite eggs or by direct contact with infected animal hosts like dogs. In humans, the most commonly affected organ is Liver followed by the Lungs. The main investigational tool is Ultrasonography but Computed Tomography (CT) and serological tests are also helpful in the diagnosis of Liver Hydatid Cysts (LHC). Although PAIR technique is the most important modality of therapy along with medical treatment, surgery has got a great role in the management of the entire spectrum of the disease. Nowadays, various Laparoscopic techniques have been safely used to improve the morbidity and mortality associated with the surgical management of the disease, and is the only other therapeutic option used all over the World. Prevention programme includes, public awareness and Education, dog deworming and slaughterhouse hygiene.

Update on the diagnosis and management of neurocysticercosis / Atualização no diagnóstico e manejo da neurocisticercose

ABSTRACT Background: Neurocysticercosis (NCC) is a serious public health problem in several developing countries, including those in Latin America, Asia, and Africa. NCC is considered to be the main cause of late-onset epilepsy in endemic areas. Objective: This review summarizes recent advances in diagnosis and therapy of NCC. Methods: Relevant articles and books were reviewed and used as a source of information for this review. Results: The diagnosis of NCC is based upon neuroimaging studies (MRI and computed tomography) and laboratory analysis of the cerebrospinal fluid (CSF). Praziquantel and albendazole are considered parasiticidal drugs against NCC, but there is an intense debate over the value and safety of these drugs. Conclusion: Given the relative scarcity of clinical trials, more comparative interventional studies, especially randomized controlled trials in long-term clinical evolution, are required in order to clarify the controversy over the validity of parasitic therapy in patients with NCC.

RESUMO Antecedentes: A neurocisticercose (NCC) é grave problema de saúde pública nos países em desenvolvimento, especialmente na América Latina, Ásia e África. A NCC é considerada a principal causa de epilepsia de início tardio nas regiões endêmicas. Objetivo: Este artigo pretende discutir os recentes avanços no diagnóstico e tratamento da NCC. Métodos: Artigos científicos e livros relevantes serviram de fonte de informação para esta revisão. Resultados: O diagnóstico da NCC é fundamentado nos exames de neuroimagem (ressonância magnética e tomografia computadorizada) e do líquido cefalorraquiano (LCR). Atualmente, praziquantel e albendazole são considerados eficazes na terapêutica etiológica da NCC, mas há intenso debate quanto à validade e segurança desses medicamentos. Conclusão: Pela relativa carência de ensaios clínicos, são necessários novos estudos particularmente randomizados, controlados e com análise de desfechos clínicos a longo prazo para o esclarecimento da polêmica envolvendo a validade da terapêutica parasiticida na NCC.

Anthelmintic activity of seaweed extract of Padina boergesenii and Padina tetrastromatica acute subacute level in naturally infected sheep

Background: Seaweeds have showed a broad range of biological activities such as antiviral, cardiovascular, autoimmune diseases, antineoplastic antibacterial, anti-inflammatory, and antifungal activities. Aims and Objectives: This study was done to assess capability of Padina boergesenii and Padina tetrastromatica extract for anthelmintic activity in sheep agonized with clinical parasitic gastroenteritis in different concentrations and compared it against the standard drug albendazole using natural acute/subacute parasitic gastroenteritis due primarily to mixed nematode species. Materials and Methods: The anthelmintic activity of ethanolic extract of seaweed of P. boergesenii was studied in sheep with natural acute/subacute parasitic gastroenteritis due primarily to mixed nematode species. Graded doses of the extract (100, 200, and 300 mg/kg, p.o for 5 consecutive days) significantly reduced fecal egg counts in infected animals. The percentage reduction (96.1%) by 300 mg/kg of the extract was comparable to that of 5 mg/kg of albendazole (94.3%). Results: The administration of the extract resulted in improved hemoglobin and leukocytosis values in worm infected sheep. Conclusion: The current study evidence that the anthelmintic activity of the ethanolic extract of seaweed of P. boergesenii and P. tetrastromatica has promising anthelmintic activity against strongyle, Strongyloides papillosus, and Taenia ovis. However, the anthelmintic activity of P. boergesenii was superior to P. tetrastromatica.

Proteinuria associated with hookworm infection: a case report / 中国血吸虫病防治杂志

As a common soil-borne nematode, hookworm is mainly parasitized in the intestine, and the clinical manifestations of hookworm infections mainly include gastrointestinal symptoms and iron-deficiency anemia. In addition, hookworm may be also parasitized in other organs in addition to gastrointestinal system, resulting in development of disorders in other systems. Proteinuria caused by hookworm infections is rare and easy to be misdiagnosed in clinical practices. Hereby, the diagnosis and treatment of a case of proteinuria associated with hookworm infections was reported, in order to increase the understanding of hookworm infection-associated proteinuria among clinicians.

Higher efficacy of a single dosage albendazole and different soil-transmitted helminths re-infection profiles amongst indigenous Negritos from inland jungle versus those in resettlement at town peripheries

@#Demarginalization through initiation of resettlement program since 1978 is an inevitable progress faced by the indigenous Orang Asli (OA) population in Peninsular Malaysia. As Malaysian huntergatherers, the Negrito has been exposed to various environmental-cultural variations. These changes may influence the pattern of soil-transmitted helminth (STH) infections, the common malady amongst OA. This study evaluated the deworming effects of single-dosage albendazole (400 mg) and STH-reinfection rate between Negritos who are still living in the inland jungle versus those living in resettlements at town peripheries (RPS). Stool samples from the consented participants were first examined using the direct faecal smear, formalin-ether sedimentation and Kato Katz techniques. Subsequently, stool collections were carried out in three time points following treatment (i.e., 21 days, 3 months and 6 months). In brief, a total number of 54 Negritos (inland: 24; RPS: 30) with a complete set of stool collection was included in this longitudinal study. This study revealed 72.2% cure rate against T. trichiura in the inland but only 15.0% in the RPS. Although the efficacy of albendazole against T. trichiura was ultimately low in the RPS, 62.6% egg reduction rate (ERR) (arithmetic mean) was noted (p = 0.001). For A. lumbricoides and hookworm, high cure rates were found in both communities (85.7–100.0%). Reinfection for T. trichiura was seen in less than 1 month with higher rate in the RPS (90.0%) as opposed to the inland (44.4%) at 21 days following treatment. This study found that the inland OA had better tolerability to single-dosage albendazole and experienced slower STH reinfection rates versus the RPS. Hence, the selection of albendazole dosage should be targeted and the use of single- dosage albendazole (biannually) would be more suitable for the inland OA. Conversely, we propose the use of 3-days albendazole regimens in the resettled RPS population.

Brain lesions associated with eosinophilia. A useful clue for neurotoxocariasis. Report of one case

ABSTRACT Neurotoxocariasis is uncommon. Its manifestations include events of meningitis, encephalitis and less frequently vasculitis, which manifest as headache, seizures, focalization, confusion, cognitive alterations and /or fever. Peripheral eosinophilia with clinical and neurological imaging elements, allow its early suspicion. We report a 48-year-old agricultural worker, admitted in our hospital for one week of gastrointestinal complaints, headache, progressive left hemiparesis and impaired consciousness. He had leukocytosis (13,530/μL) with peripheral eosinophilia (25%, absolute count 3,400 /μL). CSF analysis revealed no abnormalities and brain CT showed poorly defined hypodense lesions on subcortical areas and semioval centers. Magnetic resonance imaging showed multiple foci with increased signals predominantly in the white matter in both hemispheres, especially at frontal and occipital regions and at semioval centers. Lesions reinforced after paramagnetic contrast. Serological studies found specific IgG antibodies by ELISA against antigens of the genus Toxocara, which were confirmed by a positive IgG Western Blot. The patient was treated with albendazole (800 mg/d) for 14 days associated with parenteral and then oral corticosteroids with a favorable response and gradual complete recovery.

La neurotoxocariasis es infrecuente. Sus manifestaciones incluyen eventos de meningitis, encefalitis y con menor frecuencia vasculitis, que se manifiestan como cefalea, convulsiones, focalización, confusión, alteraciones cognitivas o fiebre. La eosinofilia periférica, junto a elementos clínicos e imágenes compatibles, permiten su sospecha. Informamos el caso de un trabajador agrícola de 48 años que ingresó por una semana de molestias gastrointestinales, cefalea, hemiparesia izquierda progresiva y deterioro de conciencia. Los exámenes revelaron leucocitosis (13.530/μL) con eosinofilia periférica (25%, recuento absoluto 3.400/μL). El análisis del LCR sin anomalías y la tomografía computada cerebral mostró lesiones hipodensas mal definidas en áreas subcorticales y centros semiovales. La resonancia magnética mostró múltiples focos con aumento de la señal predominantemente en la sustancia blanca en ambos hemisferios. Las lesiones presentaron refuerzo tras contraste paramagnético. Los estudios serológicos indicaron anticuerpos IgG específicos por ELISA contra antígenos del género Toxocara. El paciente fue tratado con albendazol (800 mg /día) durante 14 días asociado a corticoides con respuesta favorable y una recuperación gradual completa.

Punica granatum and amygdalin extracts plus cobalamin combined with albendazole reduce larval burden and myositis in experimental trichinosis / Extratos de Punica granatum e amígdalina mais cobalamina combinado com albendazol reduzem a carga larvar e a miosite na triquinose experimental

Abstract Trichinellosis is a zoonosis results from eating raw or semi-cooked meat of infected animals. Medicinal plants have been used lately as alternatives and/or combined therapies to resolve some drawbacks of the current regimens. This work analyzed the effect of albendazole monotherapy on Trichinella spiralis experimental infection (group A), in comparison to P. granatum and amygdalin extracts +cobalamin (group B), plus its combination with albendazole (group C). The study revealed that the extracts alone or combined with albendazole had an inferior effect to albendazole monotherapy regarding number of adult worms (40.83 ±3.82, 18.67 ±1.86 and 16.83 ±2.32, respectively). However, their effect was more obvious in muscle phase combined with albendazole, achieving the lower number of larvae/mL tissue homogenate (22.33 ±3.27 in comparison to 39.67 ±2.58 achieved by albendazole monotherapy). The extracts exerted a significant immunomodulatory effect by reducing the local CD4+ expression in the intestine as well as in muscle phase (1.15 ±0.25 and 3.80 ±0.65 in comparison to 4.97 ±0.37 and 12.20 ±0.87 with albendazole monotherapy, respectively). So, these extracts improved the therapeutic efficacy of albendazole, specifically in muscle phase and counteracted the inflammatory reaction caused by albendazole monotherapy, thus extensively alleviating the resulting myositis.

Resumo Trichinellosis é uma zoonose resultante da ingestão de carne crua ou semicozida de animais infectados. As plantas medicinais têm sido usadas, ultimamente, como alternativas e/ou terapias combinadas, para resolver algumas desvantagens dos regimes atuais. Este trabalho analisou o efeito da monoterapia albendazole na infecção experimental por Trichinella spiralis (grupo A), em comparação com extratos de P. granatum e amígdalina +cobalamina (grupo B), além de sua combinação com albendazol (grupo C). O estudo revelou que os extratos sozinho ou combinado com albendazol teve efeito inferior à monoterapia albendazol em relação ao número de vermes adultos (40,83 ±3,82, 18,67 ±1,86 e 16,83 ±2,32, respectivamente). No entanto, seu efeito foi mais óbvio na fase muscular combinado com o albendazol, alcançando o menor número de larvas/mL homogeneizado de tecido (22,33 ±3,27 em comparação com 39,67 ±2,58 obtidos pela monoterapia albendazol). Os extratos exerceram um efeito imunomodulatório significativo, ao reduzir a expressão local CD4+ no intestino, bem como na fase muscular (1,15 ±0,25 e 3,80 ±0,65 em comparação com 4,97 ±0,37 e 12,20 ±0,87 com monoterapia albendazol, respectivamente). Assim, esses extratos melhoraram a eficácia terapêutica do albendazol, especificamente na fase muscular e neutralizaram a reação inflamatória causada pela monoterapia albendazol, aliviando extensivamente a miosite resultante.

COVID-19: The Ivermectin African Enigma / COVID-19: El enigma de la Ivermectina en Africa

Abstract Introduction: The low frequency of cases and deaths from the SARS-CoV-2 COVID-19 virus in some countries of Africa has called our attention about the unusual behavior of this disease. The ivermectin is considered a drug of choice for various parasitic and viral diseases and shown to have in vitro effects against SARS-CoV-2. Aims: Our study aimed to describe SARS-CoV2 infection and death rates in African countries that participated in an intensive Ivermectin mass campaign carried out to control onchocerciasis and compare them with those of countries that did not participate. Methods: Data from 19 countries that participated in the World Health Organization (WHO) sponsored African Programme for Onchocerciasis Control (APOC), from 1995 until 2015, were compared with thirty-five (Non-APOC), countries that were not included. Information was obtained from https://www.worldometers.info/coronavirus/ database. Generalized Poisson regression models were used to obtain estimates of the effect of APOC status on cumulative SARS-CoV-2 infection and mortality rates. Results: After controlling for different factors, including the Human Development Index (HDI), APOC countries (vs. non-APOC), show 28% lower mortality (0.72; 95% CI: 0.67-0.78) and 8% lower rate of infection (0.92; 95% CI: 0.91-0.93) due to COVID-19. Conclusions: The incidence in mortality rates and number of cases is significantly lower among the APOC countries compared to non-APOC countries. That a mass public health preventive campaign against COVID-19 may have taken place, inadvertently, in some African countries with massive community ivermectin use is an attractive hypothesis. Additional studies are needed to confirm it.

Resumen Introducción: La baja frecuencia de casos y muertes por el virus SARS-CoV-2 COVID-19 en algunos países de África llamó nuestra atención sobre el comportamiento inusual de esta enfermedad. La ivermectina se considera un fármaco de elección para diversas enfermedades parasitarias y virales, y se ha demostrado que tiene efectos in vitro contra el SARS-CoV-2. Objetivos: Nuestro estudio tiene el objetivo describir las tasas de infección y mortalidad del SARS-CoV-2 en los países africanos que participaron en una campaña intensiva masiva de ivermectina para el control de la oncocercosis y compararlas con las de los países que no participaron. Métodos: Los datos de 19 países que participaron en el Programa Africano para el Control de la Oncocercosis (APOC) patrocinado por la Organización Mundial de la Salud (OMS), desde 1995 hasta 2015, se compararon con 35 países que no fueron incluidos (NO APOC). La información sobre casos y muertes por COVID-19 se obtuvo de la base de datos https://www.worldometers.info/coronavirus/. Se utilizaron modelos de regresión de Poisson para obtener estimaciones del efecto del estado APOC sobre las tasas acumuladas de infección y mortalidad por SARS-CoV-2. Resultados: Después de controlar diferentes factores, incluido el Índice de Desarrollo Humano (IDH), los países APOC (frente a los no APOC) mostraron una mortalidad 28% menor (razón de tasas ajustada: RR= 0.72, IC 95%: 0.67-0.78) y una tasa de infección 8% menor (RR= 0.92, IC 95%: 0.91-0.93) por COVID-19. Conclusiones: Las tasas de mortalidad e infección son significativamente más bajas en países APOC en comparación con los países no APOC. Una campaña preventiva masiva de salud pública contra el COVID-19 pudo haber tenido lugar inadvertidamente en algunos países africanos con un uso masivo de ivermectina en la comunidad es una hipótesis atractiva. Se necesitan estudios adicionales para confirmarlo.

Hydatid disease in children: a single centre study with analysis of treatment protocol

Background: Hydatid disease or hydatidosis is a zoonosis which is still an important health hazard in the world. This disease is a parasitic infestation which is endemic in many sheep and cattle raising areas of the world including India. The aim of this study was to evaluate the clinical features, diagnosis, and treatment of hydatid cyst in pediatric population.Methods: This prospective study evaluated 32 pediatric patients with hydatid cyst who were treated at Geetanjali Hospital, Udaipur from 2016-2018. Medical records of these patients were studied and analyzed.Results: 32 cases were in the age group of 7 to 14 years and were from rural background/ farming community and of low socioeconomic status. Male children, lungs were predominantly involved. Cattle rearing were common to the households of all patients. Ultrasonography and computed tomography scan were done in all patients and was the main diagnostic modality. All cases were managed surgically along with albendazole therapy and had complete recovery with no recurrence till date in any of our patients.Conclusions: Hydatid disease is not rare in the pediatric age group. The liver and lung are commonly involved, but it may also present as primary disease in unusual sites like the spleen and brain. Careful surgery to avoid spillage with full course of drug therapy with albendazole can ensure permanent cure. A 28 day post-operative course was sufficient in majority of the cases. The disease can be prevented by proper community based measures like availability of clean water, sanitation and drug prophylaxis.

Baja prevalencia de Enterobius vermicularis en niños de los "Centros infantiles del Buen Vivir" Cantón Jipijapa, Ecuador / Low prevalence of Enterobius vermicularis in children of "Centros infantiles del Buen Vivir" Canton Jipijapa, Ecuador

Enterobius vermicularis es un helminto que afecta principalmente a niños. El objetivo del estudio fue determinar la prevalencia de E. vermicularis en 70 preescolares de Jipijapa, Ecuador. Se identificó un solo niño con el helminto; esto puede atribuirse al tratamiento con Albendazol que los niños escolarizados reciben regularmente en el país

Enterobius vermicularis, is a helminth that mainly affects children. The objective of the study was to determine the prevalence of E. vermicularis in 70 preschoolers in Jipijapa, Ecuador. A single child was identified with the helminth; this can be attributed to the Albendazole treatment that school children receive regularly in the country

Hydatid cyst of broad ligament: a rare case report

Hydatid cyst is a parasitic disease caused by tapeworm Echinococcus. It affects the liver and lung most commonly, but may rarely affect fallopian tube, broad ligament and other structures. One such peculiar case is where a 17 years old female presented with a rapidly growing cystic mass in lower abdomen, clinically suspicious of ovarian mass or mesentric cyst. Investigations failed to identify the nature. On laparotomy, excision of the mass was done. Suprisingly histopathological examination identified the lesion as hydatid cyst arising from the broad ligament. Patient responded well to surgical excision followed by albendazole administration. Female genital tract hydatidosis is a rare entity and in most cases the involvement is secondary. Primary hydatid disease of female genital tract is even very rarer and generates considerable diagnostic difficulty.

Gastrointestinal nematode infections do not hinder the development of Simmental X Nellore crossbred calves raised with a nutritionally enhanced diet / Infecções por nematódeos gastrintestinais não prejudicam o desenvolvimento de bezerros Simental x Nelore criados em plano nutricional elevado

Abstract An evaluation was made of the effect of anthelmintic treatments on the performance of Simmental X Nellore crossbred calves before and after weaning. To this end, the calves were divided into three groups: (1) treated monthly with a low efficacy anthelmintic drug, ivermectin; (2) treated monthly with a highly effective anthelmintic drug, albendazole; and (3) untreated control group. All the groups in this experiment showed an average fecal egg count of less than 400 eggs per gram (EPG), and no clinical signs of parasitic gastroenteritis. The blood variables were within the normal range and no calf presented anemia. In most of the samplings, mean EPGs were significantly lower (P<0.05) in the group treated with albendazole. The calves received dietary supplementation before and after weaning, which enabled them to gain weight in every month of the experiment and reach a body weight of about 250 kg on the last sampling date, before turning one year old. The anthelmintic treatments did not affect body weight gain, leading to the conclusion that, when fed with suitable dietary supplements, Simmental X Nellore crossbred calves are not affected by gastrointestinal nematode parasites acquired by grazing.

Resumo O objetivo do experimento foi avaliar o efeito de tratamentos anti-helmínticos no desempenho de bezerros Simental x Nelore antes e após o desmame. Os bezerros foram alocados em três grupos: (1) tratado mensalmente com anti-helmínticos de baixa eficácia, ivermectina; (2) tratado mensalmente com anti-helmíntico de alta eficácia, albendazol e (3) controle não tratado. A média das contagens de ovos de nematoides durante o experimento foi inferior a 400 ovos por grama (OPG) em todos os grupos sem manifestação clínica de gastroenterite parasitária. As variáveis ​​sanguíneas mantiveram-se dentro dos limites de normalidade e nenhum bezerro apresentou anemia. Na maioria das coletas, as médias de OPG foram significativamente inferiores (P<0,05) no grupo tratado com albendazol. Os bezerros receberam suplementação antes e depois do desmame, o que lhes permitiu ganhar peso em todos os meses do experimento, atingindo peso corporal em torno de 250 kg, ao final do experimento, antes de completarem um ano de idade. Não houve efeito dos tratamentos anti-helmínticos no ganho em peso, o que permitiu concluir que bezerros Nelore x Simental não são afetados pelo parasitismo por nematoides gastrintestinais sob condições de pastejo, quando devidamente suplementados com concentrado.
