Infection of the peritoneal cavity with cestode larvae, presumptively diagnosed as tetrathyridia of the genus Mesocestoides, was found by exploratory celiotomy in a dog with clinical signs consisting of episodic anorexia, vomiting, and depression. Lymphopenia and hypoalbuminemia were associated clinicopathologic abnormalities. Dystrophic calcification and midline duodenal displacement were found on abdominal radiographs. Therapy with mebendazole was instituted after recurrence of the initial episodic clinical signs postoperatively. Daily use of mebendazole for intermittent periods of up to 3 months led to remission of gastrointestinal signs for 30 months. However, 17 months after the initial diagnosis, infection of the vaginal tunic of the testicle with similar cestode larvae necessitated castration and removal of the vaginal tunic to the inguinal ring. Mebendazole therapy was reinstituted and continued for 31/2 months postoperatively. The dog was free of clinical signs of infection during and for the 16 months since this period of treatment.

Giardia lamblia has a cosmopolitan distribution. The organism exists in two stages--the trophozoite and the cystic stage. Infected children may have acute or chronic diarrhea, crampy abdominal pain, anorexia, malasorption and poor weight gain and may be misdiagnosed as celiac disease. Infection may be selflimited or chronic even over years. Diagnosis is usually made by finding the characteristic cyst in stool specimens or by duodenal aspiration. Histological sections and impression smears (AMENT) of intestinal mucosa biopsies have been proved to be the most reliable method for detecting giardiasis. Evaluation of impression smears for parasites is easier and quicker than examining serial sections of biopsies. Out of 175 selected patients with intestinal complaints which were undergone small intestinal biopsy 11 were infected with giardia lamblia (6.2%). All infected children were symptomatic, malabsorption could be demonstrated in 5/8, lactase levels were reduced in most children. Examination of duodenal aspirates, stool specimens and histological sections (routine histology) alone would not have been diagnostic in every case. Evaluation of impression smears proved to be a reliable method in detecting giardia lamblia infection and is recommended whenever an intestinal biopsy is performed.

Groups of Swiss white mice weighing 25-28 grams were infected orally with 500, 2,000, 5,000 or 20,000 oocysts of Eimeria falciformis var pragensis. Depression, anorexia, weight loss, diarrhea or dysentery, and dehydration were most pronounced at eight to ten days postinfection. The highest mortality, 31%, occurred in mice infected with 20,000 oocysts. None of the mice infected with 500 oocysts died. The pathological findings were equally severe in mice infected with 5,000 and 20,000 oocysts. The enteric lesions, most pronounced at eight to ten days postinfection, were restricted mainly to the large intestine and consisted initially of both cryptal and absorptive epithelial cell destruction and submucosal edema. These changes were followed in 12 to 24 hours by a transient influx of neutrophils into the lamina propria followed by mononuclear cell infiltration which lasted for five to ten days. As the infective dose decreased, the inflammatory response occurred later and was less extensive. When seen, hemorrhage occurred seven to 11 days postinfection. In 50% of the mice infected with 5,000 and 20,000 oocysts, varying degrees of a nonselective mucosal necrosis were seen at eight to 12 days postinfection. In mice infected with 500 oocysts, mucosal destruction was restricted to the epithelium. Neutrophils predominated when necrosis was extensive, otherwise, mononuclear cells were the main inflammatory cells. Two to three days following necrosis, crypt hyperplasia was marked and mucosal integrity was restored. Ulcers, some of which extended into the submucosa, healed by days 14 to 20. Localized granulomatous colitis, induced by trapped oocysts within the lamina propria, was seen until the experiment was terminated at 25 days postinfection. Infection was followed by lymphoid hyperplasia in the lymph nodes and the spleen.

Interactions between malnutrition and infection contribute directly to the health of individuals and communities. The relevance of this concept to the practice of clinical medicine, dentistry, and public health is supported by an imposing collection of evidence from the clinic, laboratory, and field. Malnutrition can interfere with any body mechanism that acts as a barrier to the multiplication or progress of infectious agents. This includes formation of specific antibodies, number and activity of phagocytes, integrity of skin, mucous membranes, and other tissues. Some of the less definite, nonspecific protective substances in body fluids are also affected by malnutrition. Infectious disease adversely influences the nutritional state in several indirect ways. Loss of appetite and intolerance for food result in metabolic changes. Cultural factors lead to substitution of less nutritious diets as a presumed therapeutic measure and to administration of purgatives, antibiotics, and other medicines that reduce digestion or absorption of specific nutrients. All of these may help to precipitate kwashiorkor in children subsisting on protein-deficient diets. Classical nutritional deficiencies precipitated by infection in individuals with borderline nutrient depletion include: keratomalacia due t avitaminosis-A; scurvey from lack of ascorbic acid; beriberi as a consequence of inadequate thiamin; pellagra resulting from insufficient niacin; macrocytic anemia due to folic acid or vitamin B12 deficiency; and microcytic anemia resulting from a shortage of iron. In well nourished individuals, body reserves and normal dietary intake assure that malnutrition will not result unless infection is prolonged.

During neurophysiologic studies in the rat [Crl:COBS CD(SD)BR], chloral hydrate was given intraperitoneally to produce anesthesia for brain electrode implantation. The incidental occurrence of adynamic ileus in six of these rats, 5-16 days after surgery, prompted further investigation. Pathological evaluations and transmission experiments using ingesta and viscera from affected rats failed to reveal an infectious agent. Subsequently chloral hydrate-induced adynamic ileus leading to morbidity or death was experimentally produced in 14 of 27 rats, 3--36 days after intraperitoneal administration of the anesthetic at a dose of 400 mg/kg body weight and concentrations of 125--275 mg/ml. The experimentally produced condition was characterized by lethargy, anorexia, abdominal distension, ruffled hair coat, inactivity, drowsy expression, constipation, and death. Gross pathologic findings included gaseous distension and atony of the cecum and segments of the small intestine. Small intestine contents varied from liquid to solid. The colon and rectum contained only a few dry hard fecal pellets. A few animals showed excess abdominal fluid. Microscopic findings were limited to focal chronic serositis and serosal fibrosis affecting the visceral peritoneum. On the basis of the experimental studies, it was concluded that the condition described was not an infectious disease but was an abnormal physiologic condition produced by the irritating or pharmacologic action of chloral hydrate given at high concentrations in the abdominal cavity.

Bacterial endocarditis caused by Actinobacillus actinomycetemcomitans is a rare disease. A 48-year-old man who had a Starr-Edwards aortic valve prosthesis inserted in 1972 was admitted for evaluation of confusion, headaches, anorexia, weight loss, diarrhea and weakness. Six blood cultures yielded gram-negative organisms which were subsequently identified as A. actinomycetemcomitans. Treatment with ampicillin and gentamicin resulted in cure which has been maintained after an observation period of eleven months. This represents the second report of A. actinomycetemcomitans endocarditis in a patient with a prosthetic valve.

Infection of pigs by the whipworm (Trichuris suis) resulted in profuse diarrhea on postinfection days 17 to 21. Anorexia, retardation of growth, dehydration, and emaciation were observed in infected pigs. Scanning electron micrography showed nematodes embedded in the mucosa of the cecum and colon, with resultant disruption of the mucosa. Infected pigs had decreased values of albumin, amylase, calcium and creatine phosphokinase, but increased values of alpha-, beta-, and gamma- globulins, total iron-binding capacity, copper, potassium, uric acid, and aspartate aminotransferase.

A prospective study of a Guatemalan village population demonstrated the adverse effects of infection on the nutritional and growth status of the population from gestation onward. There was a higher rate of maternal morbidity and fetal antigenic stimulation compared to industrialized societies. Infection of the young child was common, and although many infections were silent, morbidity rates were extremenly high, particularly during the protracted weaning period (6 to 24 months). Infectious diseases contributed significantly to weight loss, arrest in height, and impaired physical growth, as well as to severe malnutrition and death. Although analysis of the dietary data of fully weaned children revealed no deficiency in protein intake, most children were found to have very low calorie intake. Infectious diseases were a common cause of anorexia and of marked reduction in calorie intake. A strong inverse relationship was found between infectious disease and calorie intake in the second year of life, when children were being weaned. Infection is the most critical factor in the causation of malnutrition in the village. Health and nutrition policies should be reoriented in view of failures of food supplement programs in many parts of the world.

10 patients with anorexia nervosa were compared with controls with normal weight, regarding their peripheral blood polymorphonuclear (PMN) granulocyte reactions. The anorexia patients showed a statistically significant decrease in PMN bactericidal capacity and PMN adherence. The mean chemotaxis did not differ, but in two of the anorexia patients chemotaxis was almost absent. The intracellular activity of alkaline phosphatase was below the reference values in 5 of the 6 patients in whom it was investigated. It is concluded that changes in granulocyte function may be noted in anorexia nervosa, but their clinical significance is uncertain, as no patients had recurrent or severe infectious diseases.

The objective of this paper is to characterize the fat cow syndrome. This condition refers to a combination of metabolic, digestive, infectious, and reproductive conditions which affects the obese periparturient cow. The condition develops primarily due to faulty feed management which permits excessive consumption of unbalanced diets. The syndrome is frequently a herd problem characterized by a high morbidity and mortality due to an increase in disease in periparturient cows. Clinical signs include depression, anorexia, ketonuria, marked decrease in production, progressive debilitation, weakness, nervous signs, and an elevation in temperature due to infectious disease. The obesity is generalized throughout the body with extensive fatty metamorphosis in the liver. Histological changes are primarily in the liver and kidney. Treatment of the condition consists of feeding a balanced diet, symptomatic treatment, and good supportive care. The condition can be prevented by feeding a balanced diet according to nutrient requirements of the National Research Council.
