Penicillium chrysogenum endophthalmitis

Infections caused byPenicillium chrysogenum are rare. The first case of posttraumatic endophthalmitis caused by this saprophytic fungus is reported. Therapy with amphotericin B and topical natamycin eradicated the organism.     

Orbital hydatid cyst of Echinococcus oligarthrus in a human in Venezuela

This study reports the first known case of human hydatid disease caused by the larval stage of Echinococcus oligarthrus. The patient, a native Venezuelan female, presented a single cyst localized intraorbitally behind the left eye (retroocular), which was discovered by computed tomography. The cyst was removed by surgery, and after parasitological studies it was identified as an E. oligarthrus hydatid cyst. This is also the first case of intraorbital hydatid cyst in humans in Venezuela.     

Guttural pouch mycosis by Emericella nidulans in a horse

A case of guttural pouch mycosis in a horse caused by Emericella nidulans is reported for the first time in Spain. The high incidence of E. nidulans in this special kind of mycoses is discussed.     

一种引致人体原发性皮肤毛霉病的非高温根毛霉属真菌

由石家庄中国人民解放军白求恩国际和平医院皮肤科李成龙大夫提供的一株人体皮肤病菌经我们研究鉴定为毛霉目(Mucorales)毛霉科(Mucoraceae)根毛霉属(Rhizomucor)的一个种,并定名为多变根毛霉新种(Rhizomucor variabilis Zheng & G.-q.Chen sp. nov.)。据李大夫介绍,这株菌是从一名居住在江苏农村到该医院看病的女病人的手上病部分离的。这个病人没有一般真菌病病人所患有的其他疾病如糖尿病、白血病等等。她也没有患有其他毛霉病,因此她的皮肤毛霉病是原发性的而不是继发性的。我们查阅文献结果,国内由根毛霉属真菌引致的毛霉病过去仅有过一次肺部感染的报道;国外则有过较多次数的由根毛霉引致的人体毛霉病,主要为肺部疾病并可引致继发性的皮肤病,尚未见有由根毛霉属引起的原发性皮肤毛霉病的报道。无论国内、外引起人体毛霉病的根毛霉均为微小根毛霉[Rhizomucor pusillus(Lindt) Schipper,包括Mucor pusillus Lindt,Mucor parasiticus Lucet & Costanin等异名]一种。因此,本病例为我国第二例由根毛霉弓l起的人体毛霉病及第一例由根毛霉引起的人体皮肤毛霉病,同时又是全世界第一例由根毛霉属除微小根毛霉以外的另外一个种引起的人体毛霉病,很可能还是全世界第一例由根毛霉引起的人体原发性皮肤毛霉病。多变根毛霉与根毛霉属内所有过去已报道过的种都有显著差异。它的最适生长温度为24-30℃,最低9℃,最高38℃;其他种均为高温真菌,它们的最高生长温度可达55℃或更高。形态方面,多变根毛霉也与属内其他已知种明显不同。它的菌落高达4-8 mm并呈鲜明的浅黄色;其他已知种菌落低矮,除奈尼塔尔根毛霉(Rhizomucor nainitalensis Joshi)外全部为深暗灰色,奈尼塔尔根毛霉菌落色泽虽然较浅,但为浅灰或灰黄色,与多变根毛霉的鲜明黄色不同。它的假根异常发达并可从菌体的各个部位如菌丝、匍匐丝、孢子枝、孢子囊、囊轴上长出;其他已知种的假根一般都不发达且从未见有从孢子枝、孢子囊、囊轴等处长出的描述。它的孢子枝的分枝常常长于主枝;其他已知种则分枝长度一般不超过主枝。它的囊轴形状多变:球形、近球形、扁球形、卵形、椭圆形、梨形等等,两边对称或不对称,溢缩或不绕缩,纵向深裂或不作纵向深裂;其他已知种的囊轴形状通常为倒卵形至梨形的规则形状。它的囊领明显;其他已知种的囊领均很不明显至缺如。它的孢囊孢子形状和大小变化都较大,卵形、椭圆形、矩圆形、近球形、近三角形或其他各种不规则形状,长度范围2.5-16.5 μm;其他已知种除上面已经提到过的奈尼塔尔根毛霉外,它们的孢囊孢子形状仅限于卵形、椭圆形、近球形等较规则的形状,长度范围总是在3-6 μm范围内,奈尼塔尔根毛霉的孢囊孢子形状虽然多变,但其决度亦在3-6 μm的范围内。此外,多变根毛霉的孢子囊、囊轴、孢囊孢子等各种构造均较大;其他已知种则较小,其中肿梗根毛霉[Rhizomucor tauricus (Milko & Schkurenko) Schipper]虽亦较大,但除此之外与多变根毛霉迥异。多变根毛霉未见有接合孢子,将我们保存的全部微小根毛霉菌株与它分别配对时,或将我们的几对别的属的(+)(-)测试菌株与它分别配对时,均未见形成接合孢子或有任何反应。     

Hydatid cyst of the uterine cervix

I report and discuss a very rare case of primary involvement of the uterine cervix by hydatid cyst a parasitic disease caused by Echinococcus granulosus, whose first and most important site is the liver. The case was misdiagnosed as an ovarian cyst until the time of operation. And this is to alert the gynaecologist to the possibility of hydatid cyst when a septated mass is found in the pelvis.     

Ophthalmomyiasis caused by a Phormia sp. (Diptera: Calliphoridae) larva in an enucleated patient

Ophthalmomyiasis rarely occurs worldwide, and has not been reported in Korea. We present here a case of ophthalmomyiasis caused by Phormia sp. fly larva in an enucleated eye of a patient. In June 2010, a 50-year-old man was admitted to Dankook University Hospital for surgical excision of a malignant melanoma located in the right auricular area. He had a clinical history of enucleation of his right eye due to squamous cell carcinoma 5 years ago. During hospitalization, foreign body sensation developed in his right eye, and close examination revealed a fly larva inside the eye, which was evacuated. The larva was proved to be Phormia sp. based on the morphology of the posterior spiracle. Subsequently, no larva was found, and the postoperative course was uneventful without any complaints of further myiasis. This is the first case of ophthalmomyiasis among the literature in Korea, and also the first myiasis case caused by Phormia sp. in Korea.     

Isolation of Epidermophyton floccosum from a dog in Norway

This report presents a case of dermatomycosis caused by Epidermophyton floccosum in a dog--the first recorded isolation of this fungus from animals in Norway.     

Kodamaea ohmeri fungemia associated with surgery

We report a case of fungemia caused by Kodamaea (Pichia) ohmeri associated with surgery in a patient with a history of diabetes and chronic renal failure. Kodamaea ohmeri is a yeast rarely involved in human infections. Since the first report of a case of fungemia in 1998, only thirteen cases of K. ohmeri infection have been so far described in the medical literature.     

The First Case of Phaeohyphomycosis Caused by Rhinocladiella basitona in an Immunocompetent Child in China

We present the first case of phaeohyphomycosis caused by Rhinocladiella basitona (R. basitona) in China and describe the mycological characteristics of this pathogen. A 11-year-old girl was presented with plaque on her face for 3 years. Diagnosis was based on histopathology, mycology, and molecular identification. The patient was treated with terbinafine and itraconazole. This case is the second of phaeohyphomycosis caused by R. basitona in the world (previously belonging to Geniculosporium).     

Effect of timing of first clinical mastitis occurrence on lactational and reproductive performance of Holstein dairy cows

Objectives of this study were to determine the influence of timing of first clinical mastitis case occurrence on lactational and reproductive performance in high producing lactating dairy cows during the first 320 days in milk (DIM). Holstein cows, 1001, from two commercial dairy farms in California were retrospectively divided into four treatment groups according to timing of first clinical mastitis case caused by environmental pathogens: control with no recorded clinical cases of mastitis (C; n=501); first clinical mastitis prior to first postpartum AI (MG1; n=250); first clinical mastitis between first postpartum AI and pregnancy diagnosis (MG2; n=147); and first clinical mastitis after diagnosed pregnant (MG3; n=103). Clinical cases of mastitis were identified at every milking by the herd personnel based on abnormal milk or swelling of the mammary gland. A fore sample of milk was aseptically collected from every clinical case for microbiological culture. Mastitis decreased yields of milk, 3.5% fat-corrected milk, and milk components, but the effect was only observed for MG1 and MG2. Cows in the control group had lower linear somatic cell count (SCC) score throughout the lactation. Culling was increased by mastitis, and cows in the mastitis groups left the study earlier than controls. Conception rate at first postpartum AI and pregnancy rate at the end of the study were both decreased by mastitis prior to or after first AI, and MG1 and MG2 cows had extended days open. Furthermore, cows experiencing mastitis during lactation had a higher incidence of abortions. The negative effects of mastitis on reproduction were observed regardless of clinical case being caused by either Gram positive or negative bacteria. Mastitis either prior to or after first postpartum AI impairs lactation performance, increases culling, and decreases reproductive efficiency in high producing Holstein dairy cows.     

Characterization of Edenia gomezpompae Isolated from a Patient with Keratitis

Edenia gomezpompae, isolated from a patient suffering from keratitis, who was an agricultural worker with a 4-year history of diabetes mellitus, is described. Fungal hyphae were detected in corneal scrapings after microscopic examination and repeated culture. Isolates were identified by morphology and by sequencing the internal transcribed spacer region of ribosomal DNA. Chlamydospore characteristics of E. gomezpompae are described for the first time. The in vitro antifungal susceptibilities of the isolate were tested using five antifungal agents. With the exception of fluconazole, the other drugs (natamycin, amphotericin B, itraconazole, and voriconazole) assayed were highly effective against this fungus. The keratitis was cured after debridement of the corneal ulcer and treatment with 5 % natamycin. After 3 months, when the patient was reexamined, the corneal ulcer showed signs of healing, with no recurrence. To our knowledge, this is the first reported case of keratitis caused by E. gomezpompae, as well as being the first known case of disease in humans caused by this species.     

First report of sylvatic DENV-2-associated dengue hemorrhagic fever in West Africa

Dengue virus (DENV) circulates in human and sylvatic cycles. Sylvatic strains are both ecologically and evolutionarily distinct from endemic viruses. Although sylvatic dengue cycles occur in West African countries and Malaysia, only a few cases of mild human disease caused by sylvatic strains and one single case of dengue hemorrhagic fever in Malaysia have been reported. Here we report a case of dengue hemorrhagic fever (DHF) with thrombocytopenia (13000/μl), a raised hematocrit (32% above baseline) and mucosal bleeding in a 27-year-old male returning to Spain in November 2009 after visiting his home country Guinea Bissau. Sylvatic DENV-2 West African lineage was isolated from blood and sera. This is the first case of DHF associated with sylvatic DENV-2 in Africa and the second case worldwide of DHF caused by a sylvatic strain.     

Septicemia due to Solobacterium moorei in a patient with multiple myeloma

We report a case of bacteremia caused by Solobacterium moorei, an anaerobic, non-sporulated Gram-positive bacillus in a patient with a multiple myeloma. The source of infection was presumably related to multiple dento-alveolar abscesses. This is the first recovery of S. moorei from blood cultures.     

Intrauterine contraceptive device-associated pelvic actinomycosis caused by Actinomyces urogenitalis

We report a case of intrauterine contraceptive device (IUD) associated pelvic actinomycosis due to Actinomyces urogenitalis in a previously healthy young adult woman. Diagnosis was confirmed by 16S ribosomal RNA gene sequencing of bacterial colonies growing from the extracted device. This is the first documented report of human infection caused by this micro-organism.     

Nosocomial submandibular infections with dipterous fly larvae

In September 1998, a case of nosocomial cutaneous myiasis caused by Lucilia sericata (Meigen, 1826) in a 77-year-old male was found. The patient had been receiving partial maxillectomy due to the presence of malignant tumor on premaxilla. This is the first verified case involving Lucilia sericata in Taegu, Korea. In the present paper, the salient morphological features of the third instar larvae involved have been studied.     

Complete genome sequence of Nocardia brasiliensis HUJEG-1

In Mexico, actinomycetoma is mainly caused by Nocardia brasiliensis, which is a soil inhabitant actinobacterium. Here, we report for the first time the draft genome of a strain isolated from a human case that has largely been found in in vitro and experimental models of actinomycetoma, N. brasiliensis HUJEG-1.     

Isolation and 16S ribosomal RNA gene sequence-based identification of Clostridium scindens from an intra-abdominal abscess

Clostridium scindens has not been previously associated with human infection. We describe a case of an adolescent female with Crohn's disease presenting with a post-surgical intra-abdominal abscess from which this organism was isolated in pure culture. This is the first documented report of human infection caused by this micro-organism.     

Gastrointestinal entomophthoramycosis caused by Basidiobolus haptosporus

There was described the first cultural proven case of gastrointestinal entomophthoramycosis caused by B. haptosporus. A review of the literature on gastrointestinal zygomycosis led us to presume that similar clinical reported cases have been also caused by this fungus. A commentary on the designation of the clinical forms of the infections caused by Zygomycetes was also made.Reprints request (Dr. Londero) Tuiuti 1809/201, 97100 Santa Maria, RS, Brazil.     

Identification of a novel IVD mutation in a consanguineous family with isovaleric acidemia

Isovaleric acidemia (IVA) is a rare autosomal recessive disorder caused by a deficiency of isovaleryl-CoA dehydrogenase encoded by IVD gene. In this case study we report the first Saudi IVA patients from a consanguineous family with a novel transversion (p.G362V) and briefly discuss likely phenotype–genotype correlation of the disease in the Saudi population. We explored the functional consequences of the mutation by using various bioinformatics prediction algorithms and discussed the likely mechanism of the disease caused by the mutation.     

Familial chylomicronemia caused by a novel type of mutation in the APOE-CI-CIV-CII gene cluster encompassing both the APOCII gene and the first APOCIV gene mutation: APOCII-CIV(Nijmegen)

Apolipoprotein CII (ApoCII) deficiency is a relatively rare cause of the chylomicronemia syndrome, a disorder characterized by severe fasting hypertriglyceridemia and massive accumulation of chylomicrons in plasma. Here we present a case which is the first example of apoCII deficiency caused by a major rearrangement in the APOCII gene. Southern blot analysis revealed an approximately 7.5-kb deletion disrupting the APOCII gene including the promotor region and first exon. Interestingly, the deletion also encompasses the APOCIV gene, a recently discovered novel gene upstream of APOCII. This deletion is the first mutation to be reported in the APOCIV gene.
